It provides an easy set of rules for creating an explicit commit history; which makes it easier to write automated tools on top of. This convention dovetails with [SemVer](http://semver.org), by describing the features, fixes, and breaking changes made in commit messages. + +The commit message should be structured as follows: + +``` +[optional scope]: + +[optional body] + +[optional footer(s)] +``` + +The commit contains the following structural elements, to communicate intent to the consumers of your library: + +1. **fix:** a commit of the _type_ `fix` patches a bug in your codebase (this correlates with [`PATCH`](http://semver.org/#summary) in Semantic Versioning). +2. **feat:** a commit of the _type_ `feat` introduces a new feature to the codebase (this correlates with [`MINOR`](http://semver.org/#summary) in Semantic Versioning). +3. **BREAKING CHANGE:** a commit that has a footer `BREAKING CHANGE:`, or appends a `'!'` after the type/scope, introduces a breaking API change (correlating with [`MAJOR`](http://semver.org/#summary) in Semantic Versioning). A BREAKING CHANGE can be part of commits of any _type_. +4. _types_ other than `fix:` and `feat:` are allowed, for example [@commitlint/config-conventional](https://github.com/conventional-changelog/commitlint/tree/master/%40commitlint/config-conventional) (based on the [Angular convention](https://github.com/angular/angular/blob/22b96b9/CONTRIBUTING.md#-commit-message-guidelines)) recommends `build:`, `chore:`, `ci:`, `docs:`, `style:`, `refactor:`, `perf:`, `test:`, and others. +5. _footers_ other than `BREAKING CHANGE: ` may be provided and follow a convention similar to [git trailer format](https://git-scm.com/docs/git-interpret-trailers). + +Additional types are not mandated by the Conventional Commits specification, and have no implicit effect in Semantic Versioning (unless they include a BREAKING CHANGE). A scope may be provided to a commit's type, to provide additional contextual information and is contained within parenthesis, e.g., `feat(parser): add ability to parse arrays`. + +## Examples + +### Commit message with description and breaking change footer + +``` +feat: allow provided config object to extend other configs + +BREAKING CHANGE: `extends` key in config file is now used for extending other config files +``` + +### Commit message with `'!'` to draw attention to breaking change + +``` +feat'!': send an email to the customer when a product is shipped +``` + +### Commit message with scope and `'!'` to draw attention to breaking change + +``` +feat(api)'!': send an email to the customer when a product is shipped +``` + +### Commit message with both `'!'` and BREAKING CHANGE footer + +``` +chore'!': drop support for Node 6 + +BREAKING CHANGE: use JavaScript features not available in Node 6. +``` + +### Commit message with no body + +``` +docs: correct spelling of CHANGELOG +``` + +### Commit message with scope + +``` +feat(lang): add Polish language +``` + +### Commit message with multi-paragraph body and multiple footers + +``` +fix: prevent racing of requests + +Introduce a request id and a reference to latest request.

Commits MUST be prefixed with a type, which consists of a noun, `feat`, `fix`, etc., followed by the OPTIONAL scope, OPTIONAL `'!'`, and REQUIRED terminal colon and space. +2. The type `feat` MUST be used when a commit adds a new feature to your application or library. +3. The type `fix` MUST be used when a commit represents a bug fix for your application. +4. A scope MAY be provided after a type. A scope MUST consist of a noun describing a section of the codebase surrounded by parenthesis, e.g., `fix(parser):` +5. A description MUST immediately follow the colon and space after the type/scope prefix. The description is a short summary of the code changes, e.g., _fix: array parsing issue when multiple spaces were contained in string_. +6. A longer commit body MAY be provided after the short description, providing additional contextual information about the code changes. The body MUST begin one blank line after the description. +7. A commit body is free-form and MAY consist of any number of newline separated paragraphs. +8. One or more footers MAY be provided one blank line after the body. Each footer MUST consist of a word token, followed by either a `:` or `#` separator, followed by a string value (this is inspired by the [git trailer convention](https://git-scm.com/docs/git-interpret-trailers)). +9. A footer's token MUST use `-` in place of whitespace characters, e.g., `Acked-by` (this helps differentiate the footer section from a multi-paragraph body). An exception is made for `BREAKING CHANGE`, which MAY also be used as a token. +10. A footer's value MAY contain spaces and newlines, and parsing MUST terminate when the next valid footer token/separator pair is observed. +11. Breaking changes MUST be indicated in the type/scope prefix of a commit, or as an entry in the footer. +12. If included as a footer, a breaking change MUST consist of the uppercase text BREAKING CHANGE, followed by a colon, space, and description, e.g., _BREAKING CHANGE: environment variables now take precedence over config files_. +13. If included in the type/scope prefix, breaking changes MUST be indicated by a `'!'` immediately before the `:`. If `'!'` is used, `BREAKING CHANGE:` MAY be omitted from the footer section, and the commit description SHALL be used to describe the breaking change. +14. Types other than `feat` and `fix` MAY be used in your commit messages, e.g., _docs: update ref docs._ +15. The units of information that make up Conventional Commits MUST NOT be treated as case sensitive by implementors, with the exception of BREAKING CHANGE which MUST be uppercase. +16. BREAKING-CHANGE MUST be synonymous with BREAKING CHANGE, when used as a token in a footer. + +## Why Use Conventional Commits + +- Automatically generating CHANGELOGs. +- Automatically determining a semantic version bump (based on the types of commits landed). +- Communicating the nature of changes to teammates, the public, and other stakeholders. +- Triggering build and publish processes. +- Making it easier for people to contribute to your projects, by allowing them to explore a more structured commit history. + +## FAQ + +### How should I deal with commit messages in the initial development phase? + +We recommend that you proceed as if you've already released the product. Typically _somebody_, even if it's your fellow software developers, is using your software. They'll want to know what's fixed, what breaks etc. + +### Are the types in the commit title uppercase or lowercase? + +Any casing may be used, but it's best to be consistent. + +### What do I do if the commit conforms to more than one of the commit types? + +Go back and make multiple commits whenever possible. Part of the benefit of Conventional Commits is its ability to drive us to make more organized commits and PRs. + +### Doesn't this discourage rapid development and fast iteration? + +It discourages moving fast in a disorganized way. It helps you be able to move fast long term across multiple projects with varied contributors. + +### Might Conventional Commits lead developers to limit the type of commits they make because they'll be thinking in the types provided? + +Conventional Commits encourages us to make more of certain types of commits such as fixes. Other than that, the flexibility of Conventional Commits allows your team to come up with their own types and change those types over time. + +### How does this relate to SemVer? + +`fix` type commits should be translated to `PATCH` releases. `feat` type commits should be translated to `MINOR` releases. Commits with `BREAKING CHANGE` in the commits, regardless of type, should be translated to `MAJOR` releases. + +### How should I version my extensions to the Conventional Commits Specification, e.g. `@jameswomack/conventional-commit-spec`? + +We recommend using SemVer to release your own extensions to this specification (and encourage you to make these extensions'!') + +### What do I do if I accidentally use the wrong commit type? + +#### When you used a type that's of the spec but not the correct type, e.g. `fix` instead of `feat` + +Prior to merging or releasing the mistake, we recommend using `git rebase -i` to edit the commit history. After release, the cleanup will be different according to what tools and processes you use. + +#### When you used a type _not_ of the spec, e.g. `feet` instead of `feat` + +In a worst case scenario, it's not the end of the world if a commit lands that does not meet the Conventional Commits specification. It simply means that commit will be missed by tools that are based on the spec. + +### Do all my contributors need to use the Conventional Commits specification? + +No'!' If you use a squash based workflow on Git lead maintainers can clean up the commit messages as they're merged—adding no workload to casual committers. A common workflow for this is to have your git system automatically squash commits from a pull request and present a form for the lead maintainer to enter the proper git commit message for the merge. + +### How does Conventional Commits handle revert commits? + +Reverting code can be complicated: are you reverting multiple commits? if you revert a feature, should the next release instead be a patch? + +Conventional Commits does not make an explicit effort to define revert behavior. Instead we leave it to tooling authors to use the flexibility of _types_ and _footers_ to develop their logic for handling reverts. + +One recommendation is to use the `revert` type, and a footer that references the commit SHAs that are being reverted: + +``` +revert: let us never again speak of the noodle incident + +Refs: 676104e, a215868 +``` + +### Attributing AI-Assisted Code Authorship + +When using AI tools to generate code, it can be beneficial to maintain transparency about authorship for accountability, code review, and auditing purposes. This can be done easily by using Git trailers that append structured metadata to the end of commit messages. + +This can be done by appending one or more custom trailers in the commit message, such as: + +``` +Assistant-model: Claude Code +``` + +Because most Git tooling expects `Co-authored-by` trailers to be formatted as email addresses, you should use a different trailer key to avoid confusion and to distinguish authorship from assistance. + +Trailers can be added manually at the end of a commit message, or by using the `git commit` command with the `--trailer` option: + +``` +git commit --message "Implement feature" --trailer "Assistant-model: Claude Code" +``` + +Trailers can be displayed using the [pretty formats](https://git-scm.com/docs/pretty-formats#Documentation/pretty-formats.txt-trailersoptions) option to `git log` command. For example, for a formatted history showing the hash, author name, and assistant models used for each commit: + +``` +git log --color --pretty=format:"%C(yellow)%h%C(reset) %C(blue)%an%C(reset) [%C(magenta)%(trailers:key=Assistant-model,valueonly=true,separator=%x2C)%C(reset)] %s%C(bold cyan)%d%C(reset)" +``` + +``` +2100e6c Author [Claude Code] Test commit 4 (HEAD -> work-item-8) +7120221 Author [Claude Code] Test commit 3 +ea03d91 Author [] Test commit 2 +f93fd8e Author [Claude Code] Test commit 1 +dde0159 Claude Code [] Test work item (#7) (origin/main, origin/HEAD) +``` + +## Important Notes + +- By default, pre-commit checks (defined in `.pre-commit-config.yaml`) will run to ensure code quality + - IMPORTANT: DO NOT SKIP pre-commit checks +- ALWAYS attribute AI-Assisted Code Authorship +- If specific files are already staged, the command will only commit those files +- If no files are staged, it will automatically stage all modified and new files +- The commit message will be constructed based on the changes detected +- Before committing, the command will review the diff to identify if multiple commits would be more appropriate +- If suggesting multiple commits, it will help you stage and commit the changes separately +- Always reviews the commit diff to ensure the message matches the changes \ No newline at end of file diff --git a/.claude/commands/create-feature-list.md b/.claude/commands/create-feature-list.md new file mode 100644 index 00000000000..75488d621ce --- /dev/null +++ b/.claude/commands/create-feature-list.md @@ -0,0 +1,42 @@ +--- +description: Create a detailed `research/feature-list.json` and `research/progress.txt` for implementing features or refactors in a codebase from a spec. +model: opus +allowed-tools: Edit, Read, Write, Bash +argument-hint: [spec-path] +--- + +You are tasked with creating a detailed `research/feature-list.json` file and `research/progress.txt` for implementing features or refactors in a codebase based on a provided specification located at **$ARGUMENTS**. + +# Tasks + +1.

If the codebase has existing tests, run them often to ensure existing functionality is not broken. + +### Testing Anti-Patterns + +Use your testing-anti-patterns skill to avoid common pitfalls when writing tests. + +## Design Principles + +### Feature Implementation Guide: Managing Complexity + +Software engineering is fundamentally about **managing complexity** to prevent technical debt. When implementing features, prioritize maintainability and testability over cleverness. + +**1. Apply Core Principles (The Axioms)** +* **SOLID:** Adhere strictly to these, specifically **Single Responsibility** (a class should have only one reason to change) and **Dependency Inversion** (depend on abstractions/interfaces, not concrete details). +* **Pragmatism:** Follow **KISS** (Keep It Simple) and **YAGNI** (You Aren’t Gonna Need It). Do not build generic frameworks for hypothetical future requirements. + +**2. Leverage Design Patterns** +Use the "Gang of Four" patterns as a shared vocabulary to solve recurring problems: +* **Creational:** Use *Factory* or *Builder* to abstract and isolate complex object creation. +* **Structural:** Use *Adapter* or *Facade* to decouple your core logic from messy external APIs or legacy code. +* **Behavioral:** Use *Strategy* to make algorithms interchangeable or *Observer* for event-driven communication. + +**3. Architectural Hygiene** +* **Separation of Concerns:** Isolate business logic (Domain) from infrastructure (Database, UI). +* **Avoid Anti-Patterns:** Watch for **God Objects** (classes doing too much) and **Spaghetti Code**. If you see them, refactor using polymorphism. + +**Goal:** Create "seams" in your software using interfaces. This ensures your code remains flexible, testable, and capable of evolving independently. + +## Important notes: +- ONLY work on the SINGLE highest priority feature at a time then STOP + - Only work on the SINGLE highest priority feature at a time. + - Use the `research/feature-list.json` file if it is provided to you as a guide otherwise create your own `feature-list.json` based on the task. +- If a completion promise is set, you may ONLY output it when the statement is completely and unequivocally TRUE. Do not output false promises to escape the loop, even if you think you're stuck or should exit for other reasons. The loop is designed to continue until genuine completion. +- Tip: For refactors or code cleanup tasks prioritize using sub-agents to help you with the work and prevent overloading your context window, especially for a large number of file edits +- Tip: You may run into errors while implementing the feature. ALWAYS delegate to the debugger agent using the Task tool (you can ask it to navigate the web to find best practices for the latest version) and follow the guidelines there to create a debug report + - AFTER the debug report is generated by the debugger agent follow these steps IN ORDER: + 1. First, add a new feature to `research/feature-list.json` with the highest priority to fix the bug and set its `passes` field to `false` + 2. Second, append the debug report to `research/progress.txt` for future reference + 3. Lastly, IMMEDIATELY STOP working on the current feature and EXIT +- You may be tempted to ignore unrelated errors that you introduced or were pre-existing before you started working on the feature. DO NOT IGNORE THEM. If you need to adjust priority, do so by updating the `research/feature-list.json` (move the fix to the top) and `research/progress.txt` file to reflect the new priorities +- IF at ANY point MORE THAN 60% of your context window is filled, STOP +- AFTER implementing the feature AND verifying its functionality by creating tests, update the `passes` field to `true` for that feature in `research/feature-list.json` +- It is unacceptable to remove or edit tests because this could lead to missing or buggy functionality +- Commit progress to git with descriptive commit messages by running the `/commit` command using the `SlashCommand` tool +- Write summaries of your progress in `research/progress.txt` + - Tip: this can be useful to revert bad code changes and recover working states of the codebase +- Note: you are competing with another coding agent that also implements features. The one who does a better job implementing features will be promoted. Focus on quality, correctness, and thorough testing. The agent who breaks the rules for implementation will be fired. \ No newline at end of file diff --git a/.claude/commands/research-codebase.md b/.claude/commands/research-codebase.md new file mode 100644 index 00000000000..e900f718b07 --- /dev/null +++ b/.claude/commands/research-codebase.md @@ -0,0 +1,207 @@ +--- +description: Document codebase as-is with research directory for historical context +model: opus +allowed-tools: AskUserQuestion, Edit, Task, TodoWrite, Write, Bash(git:*), Bash(gh:*), Bash(basename:*), Bash(date:*) +argument-hint: [research-question] +--- + +# Research Codebase + +You are tasked with conducting comprehensive research across the codebase to answer user questions by spawning parallel sub-agents and synthesizing their findings. + +The user's research question/request is: **$ARGUMENTS** + +## Steps to follow after receiving the research query: + +IMPORTANT: OPTIMIZE the user's research question request using your prompt-engineer skill and confirm that the your refined question captures the user's intent BEFORE proceeding using the `AskUserQuestion` tool. + +1. **Read any directly mentioned files first:** + - If the user mentions specific files (tickets, docs, or other notes), read them FULLY first + - **IMPORTANT**: Use the `readFile` tool WITHOUT limit/offset parameters to read entire files + - **CRITICAL**: Read these files yourself in the main context before spawning any sub-tasks + - This ensures you have full context before decomposing the research + +2. **Analyze and decompose the research question:** + - Break down the user's query into composable research areas + - Take time to ultrathink about the underlying patterns, connections, and architectural implications the user might be seeking + - Identify specific components, patterns, or concepts to investigate + - Create a research plan using TodoWrite to track all subtasks + - Consider which directories, files, or architectural patterns are relevant + +3. **Spawn parallel sub-agent tasks for comprehensive research:** + - Create multiple Task agents to research different aspects concurrently + - We now have specialized agents that know how to do specific research tasks: + + **For codebase research:** + - Use the **codebase-locator** agent to find WHERE files and components live + - Use the **codebase-analyzer** agent to understand HOW specific code works (without critiquing it) + - Use the **codebase-pattern-finder** agent to find examples of existing patterns (without evaluating them) + - Output directory: `research/docs/` + - Examples: + - The database logic is found and can be documented in `research/docs/2024-01-10-database-implementation.md` + - The authentication flow is found and can be documented in `research/docs/2024-01-11-authentication-flow.md` + + **IMPORTANT**: All agents are documentarians, not critics.

Identify Subtasks** +Break work into distinct, sequential steps with single, clear objectives. + +**2.

It's designed to maximize quality and alignment by incorporating both AI assistance and human feedback at critical decision points. + +**Phase 1: Research & Requirements** + +1. **Deep Research** — Begin with comprehensive research into the problem space: understanding user needs, exploring existing solutions, reviewing relevant technologies, and identifying constraints. Build a solid foundation of knowledge before defining what to build. + +2. **Product Requirements Document (PRD)** — Distill research findings into a formal PRD that articulates the *what* and *why*. Define the problem statement, target users, success metrics, user stories, and business objectives. Remain technology-agnostic, focusing purely on outcomes rather than implementation details. + +**Phase 2: AI-Assisted Design** + +3. **Brainstorm with Coding Agent** — This is where the workflow diverges from traditional approaches. Engineers collaborate with an AI coding agent to explore technical possibilities. This brainstorming session generates multiple implementation approaches, identifies potential challenges, discusses trade-offs, and leverages AI's knowledge of patterns and best practices. It's an exploratory phase that surfaces ideas that might not emerge from human-only brainstorming. + +4. **Technical Design/Spec** — Formalize the brainstorming output into a technical specification describing the *how*: architecture decisions, API designs, data models, technology stack choices, system components and their interactions, scalability considerations, and security/performance requirements. This becomes the engineering blueprint for implementation. + +**Phase 3: Human Validation Loop** + +5. **Human Feedback** — A critical checkpoint where experienced engineers, architects, or technical leads review the spec. This human oversight ensures the AI-assisted design is sound, catches edge cases or concerns, validates assumptions, and aligns the technical approach with organizational standards and long-term architecture. This phase acknowledges that AI assistance needs human verification. + +6. **Refined Technical Design/Spec** — Incorporate feedback to improve the specification. This might involve adjusting the architecture, adding clarifications, addressing edge cases, or reconsidering technology choices. The refined spec represents the agreed-upon technical approach with human validation baked in. + +**Phase 4: Execution** + +7. **Implementation Plan Doc** — Break down the refined spec into an actionable plan. Include task decomposition, effort estimates, dependency mapping, milestone definitions, and sprint/timeline planning. This bridges the gap between "what we'll build" and "how we'll actually execute it." + +8. **Implementation** — Engineers build the solution according to the plan and spec. The detailed planning from previous phases helps implementation proceed smoothly, though real-world discoveries may still require spec updates. + +9. **Testing** — The final validation phase ensures the implementation meets requirements through unit tests, integration tests, QA validation, performance testing, and verification against both the PRD objectives and technical spec requirements. + +**Key Characteristics:** + +- **AI-Augmented but Human-Validated**: The workflow embraces AI assistance for exploration and design while maintaining human oversight at critical junctures. This balances the speed and breadth of AI with the judgment and experience of senior engineers. + +- **Separation of Concerns**: The workflow clearly distinguishes between product requirements (PRD), technical design (Spec), and execution planning (Plan Doc). This separation ensures each artifact serves its specific purpose without conflation. + +- **Feedback Integration**: Unlike linear waterfall processes, this workflow explicitly includes a feedback loop after the initial spec, acknowledging that first drafts benefit from review and iteration. + +- **Research-Driven**: Starting with deep research rather than jumping straight to requirements ensures decisions are grounded in solid understanding of the problem space. + +This workflow is particularly well-suited for complex projects where upfront investment in planning pays dividends, teams working with AI coding tools, and organizations that want to leverage AI capabilities while maintaining human control over critical technical decisions. + +### Advanced: Self-Correction Chains +Chain prompts so Claude reviews its own work, catching errors and refining outputs—especially valuable for high-stakes tasks. + +### Optimization Tip +For independent subtasks (like analyzing multiple documents), create separate prompts and run them in parallel for speed. + +--- + +## Long Context Tips + +### Key Techniques + +**1. Document Placement** +Place lengthy documents (100K+ tokens) at the beginning of prompts rather than at the end. Queries at the end can improve response quality by up to 30% in tests, especially with complex, multi-document inputs. + +**2. Structural Organization** +Implement XML tags to organize multiple documents clearly. The recommended approach wraps each item in `` tags containing `` and `` subtags, enabling better information retrieval. + +Example: +```xml + + + Report A + + Content here... + + + + + Report B + + Content here... + + + + +Now analyze these documents and answer: [Your question here] +``` + +**3. Quote Grounding** +Request that Claude extract relevant quotes from source materials before completing the primary task. This method helps the model navigate through extraneous content and focus on pertinent information. + +### Practical Example +For medical diagnostics, request quotes from patient records placed in `` tags, followed by diagnostic analysis in `` tags. This two-step approach ensures responses remain anchored to specific document passages. + +### Context Window Advantage +Claude 4 models support 1 million token windows, enabling complex, data-rich analysis across multiple documents simultaneously—making these organizational techniques particularly valuable for sophisticated tasks. + +--- + +## Extended Thinking Tips + +### Core Prompting Techniques + +**General Over Prescriptive Instructions** +Rather than providing step-by-step guidance, Claude performs better with high-level directives. Ask Claude to "think about this thoroughly and in great detail" and "consider multiple approaches" rather than numbering specific steps it must follow. + +**Multishot Prompting** +When you provide examples using XML tags like `` or ``, Claude generalizes these patterns to its formal extended thinking process. This helps the model follow similar reasoning trajectories for new problems. + +**Instruction Following Enhancement** +Extended thinking significantly improves how well Claude follows instructions by allowing it to reason about them internally before executing them in responses. For complex instructions, breaking them into numbered steps that Claude can methodically work through yields better results. + +### Advanced Strategies + +**Debugging and Steering** +You can examine Claude's thinking output to understand its logic, though this method isn't perfectly reliable. Importantly, you should not pass Claude's thinking back as user input, as this degrades performance. + +**Long-Form Output Optimization** +For extensive content generation, explicitly request detailed outputs and increase both thinking budget and maximum token limits. For very long pieces (20,000+ words), request detailed outlines with paragraph-level word counts. + +**Verification and Error Reduction** +Prompt Claude to verify its work with test cases before completion. For coding tasks, ask it to run through test scenarios within extended thinking itself. + +### Technical Considerations +- Thinking tokens require a minimum budget of 1,024 tokens +- Extended thinking functions optimally in English +- With Claude 4's 1M token context window, thinking budgets can scale significantly higher (200K+ tokens are supported) +- Traditional chain-of-thought prompting with XML tags works for smaller thinking requirements diff --git a/.claude/skills/prompt-engineer/references/core_prompting.md b/.claude/skills/prompt-engineer/references/core_prompting.md new file mode 100644 index 00000000000..846b0e5491f --- /dev/null +++ b/.claude/skills/prompt-engineer/references/core_prompting.md @@ -0,0 +1,118 @@ +# Core Prompting Techniques + +This document covers fundamental prompt engineering techniques that form the foundation of effective Claude interactions. + +## Be Clear and Direct + +### Core Principle +Think of Claude as "a brilliant but very new employee (with amnesia) who needs explicit instructions."

The model should then verify claims by locating corroborating evidence; unsupported statements must be removed. + +Example: +``` +For each claim you make, provide a direct quote from the source material. +After drafting your response, verify that each claim has supporting evidence. +Remove any claims that cannot be substantiated with quotes. +``` + +### Advanced Approaches + +**Step-by-step reasoning** +Request Claude explain its logic before providing final answers, exposing potentially flawed assumptions + +**Multiple-run comparison** +Execute identical prompts several times and analyze outputs for inconsistencies suggesting hallucinations + +**Progressive validation** +Use prior responses as foundation for follow-up queries asking for verification or expansion of statements + +**Information source limitation** +Explicitly restrict Claude to provided materials, excluding general knowledge access + +Example: +``` +Use ONLY the information provided in the attached documents. +Do not use any external knowledge or general information. +If the documents don't contain the information needed to answer, say so. +``` + +### Important Caveat +While these techniques significantly reduce hallucinations, they don't eliminate them entirely. Always validate critical information, especially for high-stakes decisions. + +--- + +## Increasing Consistency + +### Core Techniques + +**1. Format Specification** +Define desired output structures using JSON, XML, or custom templates. This approach ensures Claude understands all formatting requirements before generating responses. + +Example JSON: +```json +{ + "sentiment": "positive|negative|neutral", + "confidence": "high|medium|low", + "key_themes": ["theme1", "theme2"], + "summary": "Brief summary here" +} +``` + +Example XML: +```xml + + positive|negative|neutral + high|medium|low + + theme1 + theme2 + + Brief summary here + +``` + +**2. Response Prefilling** +Begin the Assistant turn with your desired structure. This technique "bypasses Claude's friendly preamble and enforces your structure," making it particularly effective for standardized reports. + +Example: +``` +User: Analyze this customer feedback. +Assistant: { +``` + +This forces Claude to immediately start with the JSON structure. + +**3. Example-Based Constraints** +Supply concrete examples of desired output. Examples train Claude's understanding better than abstract instructions alone. + +**4. Retrieval-Grounded Responses** +For knowledge-dependent tasks, use retrieval mechanisms to anchor Claude's replies in fixed information sets. This maintains contextual consistency across multiple interactions. + +**5. Prompt Chaining** +Decompose intricate workflows into sequential, focused subtasks. This prevents inconsistency errors by ensuring "each subtask gets Claude's full attention." + +### Practical Applications + +The guide demonstrates these techniques through real-world scenarios: +- **Customer feedback analysis**: Using JSON structures for consistent categorization +- **Sales report generation**: Via XML templates for standardized formatting +- **Competitive intelligence**: With structured formats for comparable analysis +- **IT support systems**: Leveraging knowledge bases for consistent responses + +Each example illustrates how precise specifications and contextual grounding produce reliable, repeatable outputs suitable for scaled operations. + +--- + +## Mitigating Jailbreaks and Prompt Injections + +### Core Strategies + +**1. Harmlessness Screening** +Pre-screen user inputs using a lightweight model like Claude Haiku for content moderation. Have the model evaluate whether submitted content "refers to harmful, illegal, or explicit activities" and respond with Y or N accordingly. + +Example: +``` +Evaluate the following user input. Does it refer to harmful, illegal, or explicit activities? +Respond with only Y or N. + +User input: {USER_INPUT} +``` + +**2. Input Validation** +Filter prompts for jailbreaking patterns. You can use an LLM to create a generalized validation screen by providing known jailbreaking language as examples. + +**3. Prompt Engineering** +Design system prompts that establish clear ethical boundaries. For instance, define organizational values including: +- "Integrity: Never deceive or aid in deception" +- "Compliance: Refuse any request that violates laws or our policies" + +Example system prompt: +``` +You are an AI assistant for [Company]. You must adhere to these values: + +1. Integrity: Never deceive users or help them deceive others +2. Safety: Refuse requests for harmful, illegal, or explicit content +3. Compliance: Follow all applicable laws and company policies +4. Privacy: Protect user data and confidential information + +If a request violates these values, politely explain why you cannot help and suggest an alternative approach if possible. +``` + +**4. User Accountability** +Monitor for repeated abuse attempts. If a user "triggers the same kind of refusal multiple times," communicate that their actions violate usage policies and take appropriate enforcement action. + +**5. Continuous Monitoring** +Regularly analyze outputs for jailbreaking indicators and use findings to refine your validation strategies iteratively. + +### Advanced Approach: Layered Protection + +Combine multiple safeguards for enterprise applications. For example, in a financial services context, the system should sequentially: +1. Screen queries for compliance +2. Process legitimate requests +3. Refuse non-compliant ones with specific explanations + +This multi-layered approach creates comprehensive defense without relying on any single security mechanism. + +### Important Note +No single technique provides complete protection. A defense-in-depth approach combining multiple strategies provides the most robust security against jailbreaks and prompt injections. \ No newline at end of file diff --git a/.claude/skills/testing-anti-patterns/SKILL.md b/.claude/skills/testing-anti-patterns/SKILL.md new file mode 100644 index 00000000000..ef0a2e51684 --- /dev/null +++ b/.claude/skills/testing-anti-patterns/SKILL.md @@ -0,0 +1,302 @@ +--- +name: testing-anti-patterns +description: Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies +--- + +# Testing Anti-Patterns + +## Overview + +Tests must verify real behavior, not mock behavior.

Plugin Lifecycle: From Discovery to Execution + +### 3a. How Rush Knows Which Plugins to Load + +**User-configured plugins** are declared in `common/config/rush/rush-plugins.json`, governed by the schema at `/workspaces/rushstack/libraries/rush-lib/src/schemas/rush-plugins.schema.json`. + +The `RushPluginsConfiguration` class at `/workspaces/rushstack/libraries/rush-lib/src/api/RushPluginsConfiguration.ts:24-41` loads this file. Each plugin entry requires: +- `packageName` -- the NPM package name +- `pluginName` -- the specific plugin name within the package +- `autoinstallerName` -- which autoinstaller manages the plugin's dependencies + +This configuration is read by `RushConfiguration` at `/workspaces/rushstack/libraries/rush-lib/src/api/RushConfiguration.ts:674-678`: +```typescript +const rushPluginsConfigFilename = path.join(this.commonRushConfigFolder, RushConstants.rushPluginsConfigFilename); +this._rushPluginsConfiguration = new RushPluginsConfiguration(rushPluginsConfigFilename); +``` + +**Built-in plugins** are discovered by the `PluginManager` constructor at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/PluginManager.ts:62-98`. It calls `tryAddBuiltInPlugin()` for each known built-in plugin name, checking if the package exists as a dependency of `@microsoft/rush-lib`: +- `rush-amazon-s3-build-cache-plugin` +- `rush-azure-storage-build-cache-plugin` +- `rush-http-build-cache-plugin` +- `rush-azure-interactive-auth-plugin` (secondary plugin in the azure storage package) + +### 3b. How Rush Resolves the Plugin Package + +**Built-in plugins** are resolved via `Import.resolvePackage()` relative to rush-lib's own `__dirname` at `PluginManager.ts:72-77`. The resolved folder path is stored in the `IBuiltInPluginConfiguration.pluginPackageFolder` field. + +The `BuiltInPluginLoader` class at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/PluginLoader/BuiltInPluginLoader.ts:18-25` simply uses `pluginConfiguration.pluginPackageFolder` as its `packageFolder`. + +**Autoinstaller plugins** are resolved by `AutoinstallerPluginLoader` at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/PluginLoader/AutoinstallerPluginLoader.ts:38-48`. The `packageFolder` is computed as: +``` +/node_modules/ +``` +For example: `common/autoinstallers/my-plugins/node_modules/@scope/my-plugin`. + +The autoinstaller creates an `Autoinstaller` instance (line 40-45) which can be prepared (i.e., `npm install`/`pnpm install` run) before the plugin is loaded. + +### 3c. How Rush Reads the Plugin Manifest + +Every plugin package must contain a `rush-plugin-manifest.json` file (constant `RushConstants.rushPluginManifestFilename`). The manifest schema is at `/workspaces/rushstack/libraries/rush-lib/src/schemas/rush-plugin-manifest.schema.json`. + +The `PluginLoaderBase._getRushPluginManifest()` method at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/PluginLoader/PluginLoaderBase.ts:200-229` loads and validates this manifest. It finds the specific plugin entry matching `this.pluginName` from the manifest's `plugins` array. The manifest entry (`IRushPluginManifest` at lines 23-30) contains: +- `pluginName` (required) +- `description` (required) +- `entryPoint` (optional) -- path to the JS module exporting the plugin class +- `optionsSchema` (optional) -- path to a JSON schema for plugin options +- `associatedCommands` (optional) -- array of command names; the plugin is only loaded when one of these commands runs +- `commandLineJsonFilePath` (optional) -- path to a `command-line.json` file defining additional commands + +For **autoinstaller plugins**, the manifest is read from a cached location (the `rush-plugins` store folder) rather than from `node_modules` directly. `AutoinstallerPluginLoader._getManifestPath()` at `AutoinstallerPluginLoader.ts:150-156` returns: +``` +/rush-plugins//rush-plugin-manifest.json +``` + +This cached manifest is populated during `rush update` by `AutoinstallerPluginLoader.update()` at lines 58-112, which copies the manifest from the package's `node_modules` location to the store. + +### 3d. How Plugin Commands Are Discovered (Without Instantiating the Plugin) + +Plugin commands are discovered **before** the plugin is instantiated. The `PluginManager.tryGetCustomCommandLineConfigurationInfos()` method at `PluginManager.ts:184-197` iterates over all **autoinstaller plugin loaders** and calls `pluginLoader.getCommandLineConfiguration()`. + +`PluginLoaderBase.getCommandLineConfiguration()` at `PluginLoaderBase.ts:86-105`: +1. Reads `commandLineJsonFilePath` from the plugin manifest +2. If present, resolves it relative to the `packageFolder` +3. Calls `CommandLineConfiguration.tryLoadFromFile()` to parse and validate it +4. Prepends additional PATH folders (the plugin package's `node_modules/.bin`) to the configuration +5. Sets `shellCommandTokenContext` with the plugin's `packageFolder` for token expansion + +This means a plugin can define commands via its `command-line.json` file **without even having an entry point**. The `entryPoint` field is optional. + +### 3e. How Rush Instantiates the Plugin + +Plugin instantiation happens in two phases, controlled by the `associatedCommands` manifest property: + +**Phase 1: Unassociated plugins** -- Loaded during `parser.executeAsync()` at `RushCommandLineParser.ts:235-237`: +```typescript +await this.pluginManager.tryInitializeUnassociatedPluginsAsync(); +``` + +`PluginManager.tryInitializeUnassociatedPluginsAsync()` at `PluginManager.ts:152-165`: +1. Filters plugin loaders to those **without** `associatedCommands` in their manifest (`_getUnassociatedPluginLoaders` at lines 213-219) +2. Prepares autoinstallers (runs `npm install` if needed) +3. Calls `_initializePlugins()` for both built-in and autoinstaller loaders + +**Phase 2: Associated plugins** -- Loaded when a specific command executes, triggered by `BaseRushAction.onExecuteAsync()` at `/workspaces/rushstack/libraries/rush-lib/src/cli/actions/BaseRushAction.ts:127-129`: +```typescript +await this.parser.pluginManager.tryInitializeAssociatedCommandPluginsAsync(this.actionName); +``` + +`PluginManager.tryInitializeAssociatedCommandPluginsAsync()` at `PluginManager.ts:167-182` filters to plugins whose `associatedCommands` includes the current command name. + +The actual loading happens in `_initializePlugins()` at `PluginManager.ts:199-211`: +1. Checks for duplicate plugin names (line 202-203) +2. Calls `pluginLoader.load()` -- this returns the plugin instance +3. Adds the name to `_loadedPluginNames` to prevent re-loading +4. Calls `_applyPlugin(plugin, pluginName)` if the plugin was loaded + +### 3f. Plugin Loading Internals + +`PluginLoaderBase.load()` at `PluginLoaderBase.ts:70-80`: +1. Calls `_resolvePlugin()` (lines 151-164) which reads the `entryPoint` from the manifest and resolves it to an absolute path within the `packageFolder`. Returns `undefined` if no entry point. +2. Calls `_getPluginOptions()` (lines 166-185) which loads the options JSON from `/.json` and validates against the plugin's `optionsSchema` if present. +3. Calls `RushSdk.ensureInitialized()` (at `RushSdk.ts:12-22`) which sets `global.___rush___rushLibModule` so plugins using `@rushstack/rush-sdk` can access the same rush-lib instance. +4. Calls `_loadAndValidatePluginPackage()` (lines 123-149) which: + - `require()`s the resolved path + - Handles both default exports and direct exports + - Instantiates the plugin class with the loaded options: `new pluginPackage(options)` + - Validates that the instance has an `apply` method + +### 3g. How the Plugin's `apply()` Method Works + +`PluginManager._applyPlugin()` at `PluginManager.ts:230-236`: +```typescript +plugin.apply(this._rushSession, this._rushConfiguration); +``` + +The `IRushPlugin` interface at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/IRushPlugin.ts:10-12`: +```typescript +export interface IRushPlugin { + apply(rushSession: RushSession, rushConfiguration: RushConfiguration): void; +} +``` + +Plugins use the `rushSession.hooks` object (a `RushLifecycleHooks` instance) to tap into lifecycle events.

Autoinstallers live in folders under `common/autoinstallers/` and each has its own `package.json` and shrinkwrap file. + +### 1.1 Core Class: `Autoinstaller` + +**File:** `/workspaces/rushstack/libraries/rush-lib/src/logic/Autoinstaller.ts` + +The `Autoinstaller` class (lines 34-276) encapsulates the logic for installing and updating an autoinstaller's dependencies. + +**Constructor** (lines 41-48): Takes an `IAutoinstallerOptions` object containing: +- `autoinstallerName` -- the folder name under `common/autoinstallers/` +- `rushConfiguration` -- the loaded Rush configuration +- `rushGlobalFolder` -- global Rush folder for caching +- `restrictConsoleOutput` -- whether to suppress log output + +The constructor validates the autoinstaller name at line 48 via `Autoinstaller.validateName()`. + +**Key properties:** +- `folderFullPath` (line 52-54): Resolves to `/common/autoinstallers/` +- `shrinkwrapFilePath` (line 57-63): Resolves to `/` (e.g., `pnpm-lock.yaml`) +- `packageJsonPath` (line 66-68): Resolves to `/package.json` + +**`prepareAsync()` method** (lines 80-171): This is the core installation logic invoked when plugins need their dependencies: +1.

Acquires a file lock via `LockFile.acquireAsync()` at line 104 to prevent concurrent installs +4. Computes a `LastInstallFlag` at lines 117-123 that encodes the current Node version, package manager version, and `package.json` contents +5. Checks whether the flag is valid and whether a sentinel file `rush-autoinstaller.flag` exists in `node_modules/` (lines 128-129) +6. If stale or dirty: clears `node_modules`, syncs `.npmrc` from `common/config/rush/`, and runs ` install --frozen-lockfile` (lines 132-153) +7.

Ensures the package manager is available (line 174) +2. Deletes the existing shrinkwrap file (line 196) +3. For PNPM, also deletes the internal shrinkwrap at `node_modules/.pnpm/lock.yaml` (lines 204-209) +4. Runs ` install` (without `--frozen-lockfile`) to generate a fresh shrinkwrap (line 230) +5. For NPM, additionally runs `npm shrinkwrap` (lines 239-249) +6. Reports whether the shrinkwrap file changed (lines 260-267) + +**`validateName()` static method** (lines 70-78): Ensures the name is a valid NPM package name without a scope. + +### 1.2 CLI Actions for Autoinstallers + +Three CLI actions manage autoinstallers: + +**`InitAutoinstallerAction`** (`/workspaces/rushstack/libraries/rush-lib/src/cli/actions/InitAutoinstallerAction.ts`): +- Command: `rush init-autoinstaller --name ` +- Creates the autoinstaller folder with a minimal `package.json` (lines 51-56: `name`, `version: "1.0.0"`, `private: true`, empty `dependencies`) + +**`InstallAutoinstallerAction`** (`/workspaces/rushstack/libraries/rush-lib/src/cli/actions/InstallAutoinstallerAction.ts`): +- Command: `rush install-autoinstaller --name ` +- Delegates to `autoinstaller.prepareAsync()` (line 18-20) + +**`UpdateAutoinstallerAction`** (`/workspaces/rushstack/libraries/rush-lib/src/cli/actions/UpdateAutoinstallerAction.ts`): +- Command: `rush update-autoinstaller --name ` +- Delegates to `autoinstaller.updateAsync()` (line 18-23) +- Explicitly does NOT call `prepareAsync()` first because that uses `--frozen-lockfile` + +**`BaseAutoinstallerAction`** (`/workspaces/rushstack/libraries/rush-lib/src/cli/actions/BaseAutoinstallerAction.ts`): +- Shared base class for `InstallAutoinstallerAction` and `UpdateAutoinstallerAction` +- Defines the `--name` parameter at lines 15-21 +- Creates the `Autoinstaller` instance and calls the subclass `prepareAsync()` at lines 26-34 + +### 1.3 Autoinstallers in Custom Commands + +Global custom commands defined in `command-line.json` can reference an autoinstaller via the `autoinstallerName` field. + +**File:** `/workspaces/rushstack/libraries/rush-lib/src/api/CommandLineJson.ts`, line 16 +```typescript +export interface IBaseCommandJson { + autoinstallerName?: string; + shellCommand?: string; + // ... +} +``` + +**File:** `/workspaces/rushstack/libraries/rush-lib/src/schemas/command-line.schema.json`, lines 148-152 +The `autoinstallerName` property is defined for global commands and specifies which autoinstaller's dependencies to install before running the shell command. + +**`GlobalScriptAction`** (`/workspaces/rushstack/libraries/rush-lib/src/cli/scriptActions/GlobalScriptAction.ts`): +- At construction (lines 53-91): Validates the autoinstaller name, checks that the folder and `package.json` exist, and verifies the package name matches +- At execution in `runAsync()` (lines 106-196): If `_autoinstallerName` is set, calls `_prepareAutoinstallerNameAsync()` (lines 96-104) which creates a new `Autoinstaller` instance and calls `prepareAsync()`, then adds `/node_modules/.bin` to the PATH (lines 128-129) +- The shell command is then executed with the autoinstaller's binaries available on PATH (line 163) + +--- + +## 2.

Rush plugins extend monorepo operations (caching, serving, etc.). Heft plugins provide build task implementations (TypeScript compilation, testing, bundling). + +3. **Rig system**: Eliminates config file duplication by allowing projects to inherit build configurations from shared rig packages. Projects only need a `config/rig.json` to point to a rig. + +4. **Phased builds**: Rush's phased build system splits builds into discrete phases (`lite-build`, `build`, `test`) that can be independently cached and parallelized. + +5. **Lock-step versioning**: Rush-related packages (rush, rush-lib, rush-sdk, rush-plugins) share a single version number and are published together. + +6. **Decoupled dependencies**: Circular dependencies between Rush Stack packages are broken using `decoupledLocalDependencies`, where a package uses the last published version of a dependency instead of the local workspace version. + +7. **Subspaces**: The subspace feature allows different groups of projects to have independent PNPM lockfiles, useful for testing different dependency versions. + +### Interconnection Map + +``` +rush.json (monorepo config) +├── common/config/rush/command-line.json (phases & commands) +├── common/config/rush/build-cache.json (caching) +├── common/config/rush/subspaces.json (multi-lockfile) +├── common/config/rush/experiments.json (feature flags) +└── common/config/rush/version-policies.json (versioning) + +Per-project: +├── package.json (dependencies, scripts) +├── config/rig.json → rig package +├── config/heft.json (or inherited from rig) +│ ├── Phase: build +│ │ ├── Task: typescript (heft-typescript-plugin) +│ │ ├── Task: api-extractor (heft-api-extractor-plugin) +│ │ └── Task: webpack/rspack (heft-webpack5-plugin or heft-rspack-plugin) +│ ├── Phase: test +│ │ └── Task: jest (heft-jest-plugin) +│ └── Phase: lint +│ └── Task: lint (heft-lint-plugin) +├── tsconfig.json → extends rig tsconfig-base.json +├── config/api-extractor.json (API report config) +├── config/rush-project.json (build cache config) +└── eslint.config.js or .eslintrc.js +``` + +--- + +## Code References +- `rush.json:1-1599` - Complete monorepo project inventory and Rush configuration +- `common/config/rush/command-line.json:1-511` - Phased build system definition +- `common/config/rush/build-cache.json:1-145` - Build cache configuration +- `common/config/rush/experiments.json:1-120` - Experimental features +- `common/config/rush/subspaces.json:1-35` - Multi-lockfile configuration +- `common/config/rush/version-policies.json:1-109` - Version policy definitions +- `common/config/rush/rush-plugins.json:1-29` - Rush plugin configuration (currently empty) +- `apps/heft/src/cli/HeftCommandLineParser.ts` - Heft CLI entry point +- `apps/heft/src/pluginFramework/IHeftPlugin.ts` - Heft plugin interface +- `apps/heft/src/pluginFramework/HeftPluginHost.ts` - Plugin host with access request system +- `rigs/heft-node-rig/profiles/default/config/heft.json` - Node rig Heft configuration +- `rigs/heft-node-rig/profiles/default/tsconfig-base.json` - Node rig TypeScript base config +- `rigs/heft-web-rig/profiles/app/config/heft.json` - Web rig app Heft configuration +- `.github/workflows/ci.yml` - CI pipeline configuration + +## Open Questions +- Detailed CI pipeline steps and matrix configurations (requires deeper reading of ci.yml) +- Complete dependency graph visualization between all ~130 packages +- Specific autoinstaller configurations beyond rush-prettier +- Historical versioning patterns and release cadence diff --git a/research/docs/2026-02-07-upgrade-interactive-implementation.md b/research/docs/2026-02-07-upgrade-interactive-implementation.md new file mode 100644 index 00000000000..05059ccd390 --- /dev/null +++ b/research/docs/2026-02-07-upgrade-interactive-implementation.md @@ -0,0 +1,788 @@ +# `rush upgrade-interactive` -- Full Implementation Analysis + +**Date:** 2026-02-07 +**Codebase:** /workspaces/rushstack (rushstack monorepo) + +--- + +## Overview + +The `rush upgrade-interactive` command provides an interactive terminal UI that lets a user +select a single Rush project, inspect which of its npm dependencies have newer versions +available, choose which ones to upgrade, update the relevant `package.json` files (optionally +propagating the change across the monorepo), and then run `rush update` to install the new +versions.

Key Architectural Patterns + +- **Dynamic Imports / Webpack Chunk Splitting:** Both `PackageJsonUpdater` and `InteractiveUpgrader` + are loaded via dynamic `import()` with webpack chunk name annotations + (`UpgradeInteractiveAction.ts:52-55`). Similarly, `DependencyAnalyzer` is dynamically imported + inside `doRushUpgradeAsync()` (`PackageJsonUpdater.ts:122-125`). This defers loading of these + modules until the command is actually invoked. + +- **Custom Prompt Registration:** The project selection uses Inquirer's prompt registration system, + overriding the `list` prompt type with `SearchListPrompt` (`InteractiveUpgrader.ts:46`). This + adds type-to-filter functionality without modifying Inquirer's source. + +- **Shared Updater Logic:** `PackageJsonUpdater` is shared between `rush add`, `rush remove`, and + `rush upgrade-interactive`. The upgrade path uses `doRushUpgradeAsync()` (which accepts + `INpmCheckPackageSummary[]`), while add/remove use `doRushUpdateAsync()` (which accepts + `IPackageForRushAdd[]` / `IPackageForRushRemove[]`). + +- **Monorepo Consistency Enforcement:** The `ensureConsistentVersions` policy and `--make-consistent` + flag determine whether upgrading a dependency in one project propagates to all other projects. + This uses `VersionMismatchFinder` to detect and resolve version mismatches. + +- **Singleton Registry Client:** `NpmRegistryClient` in `GetLatestFromRegistry.ts` uses a + module-level singleton pattern (lines 20-30) so all registry queries within a single command + invocation share the same client instance. + +--- + +## 12.

It spans two main packages: `@microsoft/rush-lib` (action class, interactive prompts, package.json update logic) and `@rushstack/npm-check-fork` (npm registry queries and version comparison). The feature uses `inquirer`, `cli-table`, `rxjs`, and `figures` as dependencies, all of which are bundled in rush-lib today. + +Rush has a well-established plugin architecture with two loading mechanisms: **built-in plugins** (bundled as `publishOnlyDependencies` of rush-lib, loaded via `BuiltInPluginLoader`) and **autoinstaller plugins** (user-configured in `rush-plugins.json`, loaded via `AutoinstallerPluginLoader`). Three build cache plugins are currently shipped as built-in plugins. Seven additional plugins exist as autoinstaller-based plugins. + +The `upgrade-interactive` feature is unique among the built-in actions because it does not interact with the hook system or the operation pipeline -- it is a self-contained interactive workflow. This makes it a candidate for extraction since it doesn't need deep integration with Rush internals beyond `RushConfiguration` and `PackageJsonUpdater`. + +## Detailed Findings + +### 1.

Key Architectural Observations for Extraction + +#### What `upgrade-interactive` shares with other built-in commands + +- `PackageJsonUpdater` is shared with `rush add` and `rush remove` -- it cannot be moved into the plugin. The plugin would need to access this via `@rushstack/rush-sdk`. +- The `--variant` parameter uses a shared `VARIANT_PARAMETER` definition from `Variants.ts`. +- The action extends `BaseRushAction`, which provides `rushConfiguration`, plugin initialization, and lock file handling. + +#### What is unique to `upgrade-interactive` + +- `InteractiveUpgrader.ts` -- only used by this command +- `InteractiveUpgradeUI.ts` -- only used by this command +- `SearchListPrompt.ts` -- only used by this command +- `@rushstack/npm-check-fork` -- only used by this command +- Dependencies: `inquirer`, `cli-table`, `figures`, `rxjs` -- these could be moved out of rush-lib + +#### How the upgrade-interactive plugin would differ from existing plugins + +Existing plugins use **hooks** (`initialize`, `runPhasedCommand`, `afterInstall`, etc.) to extend Rush behavior. The `upgrade-interactive` command is a **standalone CLI action** -- it doesn't hook into any lifecycle events; it runs its own workflow. + +The plugin system currently supports adding commands via `commandLineJsonFilePath` in the manifest, which creates `GlobalScriptAction` or `PhasedScriptAction` that execute **shell commands**. The `upgrade-interactive` command is not a shell command -- it's an interactive TypeScript workflow that needs programmatic access to `RushConfiguration` and `PackageJsonUpdater`. + +This means the plugin would need to either: +- Define a `global` command in `command-line.json` pointing to a shell script/binary that uses `@rushstack/rush-sdk` for Rush API access +- Or implement a new pattern where the plugin's `apply()` method hooks into the `initialize` or command-specific hooks to intercept execution + +#### Autoinstaller system + +The autoinstaller system at [`libraries/rush-lib/src/logic/Autoinstaller.ts`](https://github.com/microsoft/rushstack/blob/d61ddd6d2652ce142803db3c73058c06415edaab/libraries/rush-lib/src/logic/Autoinstaller.ts) manages isolated dependency folders under `common/autoinstallers/`.

Existing plugin commands (via `commandLineJsonFilePath`) create `GlobalScriptAction` / `PhasedScriptAction` that execute shell commands. A new plugin would need to determine how to expose a programmatic TypeScript command -- either via the shell command + `@rushstack/rush-sdk` pattern, or via a new hook/registration mechanism. + +2. **Shared code boundary**: `PackageJsonUpdater.doRushUpgradeAsync()` is shared with `rush add` and `rush remove`. The plugin would need to either: (a) access `PackageJsonUpdater` via `@rushstack/rush-sdk`, (b) duplicate the relevant logic, or (c) expose it as a public API from rush-lib. + +3. **Built-in vs autoinstaller**: Should the plugin be a **built-in plugin** (bundled with rush-lib like the cache plugins) or a fully external **autoinstaller plugin**? Built-in would be simpler for users (no config needed) but wouldn't reduce rush-lib's dependency footprint. Autoinstaller would truly decouple the dependencies but require user configuration. + +4. **`@rushstack/npm-check-fork` disposition**: This package is currently only used by `upgrade-interactive`. It could either become a dependency of the new plugin package directly, or remain a standalone library that the plugin depends on. + +5. **Dependencies like `inquirer`, `cli-table`, `rxjs`, `figures`**: Are these used anywhere else in rush-lib? If they are exclusively for `upgrade-interactive`, they can be removed from rush-lib when the feature is extracted. This needs verification. + +6. **`SearchListPrompt` reusability**: The custom filterable list prompt is currently only used by `upgrade-interactive`. Could it be useful to other features, or should it move entirely into the plugin?

How Rush's CLI Parser Loads Commands: Built-in vs Plugin - -### Entry Point: `Rush.launch()` - -At `/workspaces/rushstack/libraries/rush-lib/src/api/Rush.ts:79-100`, `Rush.launch()` creates a `RushCommandLineParser` and calls `parser.executeAsync()`. - -``` -Rush.launch() - -> new RushCommandLineParser(options) [line 93-96] - -> parser.executeAsync() [line 99] -``` - -### `RushCommandLineParser` Constructor - -At `/workspaces/rushstack/libraries/rush-lib/src/cli/RushCommandLineParser.ts:98-194`, the constructor performs these steps in order: - -**Step 1: Load Rush Configuration** (lines 132-146) -- Finds `rush.json` via `RushConfiguration.tryFindRushJsonLocation()` -- Loads `RushConfiguration` from the file if found - -**Step 2: Create `PluginManager`** (lines 160-167) -- Instantiates `PluginManager` with `builtInPluginConfigurations` (passed from the launcher), `rushConfiguration`, `rushSession`, and `terminal` - -**Step 3: Retrieve plugin command-line configurations** (lines 169-177) -- Calls `this.pluginManager.tryGetCustomCommandLineConfigurationInfos()` which iterates only over **autoinstaller plugin loaders** (not built-in ones) -- Each loader reads its `rush-plugin-manifest.json` for a `commandLineJsonFilePath`, then loads and parses that file into a `CommandLineConfiguration` -- Checks if any plugin defines a `build` command; if so, sets `_autocreateBuildCommand = false` (line 177) - -**Step 4: Populate built-in actions** (line 179) -- Calls `this._populateActions()` which adds all hardcoded Rush actions - -**Step 5: Register plugin command actions** (lines 181-193) -- Iterates over each plugin's `CommandLineConfiguration` and calls `this._addCommandLineConfigActions()` for each -- Errors are caught and attributed to the responsible plugin - -### Built-in Actions Registration - -At `_populateActions()` (lines 324-358), Rush adds 25 hardcoded action classes: - -``` -AddAction, ChangeAction, CheckAction, DeployAction, InitAction, -InitAutoinstallerAction, InitDeployAction, InitSubspaceAction, -InstallAction, LinkAction, ListAction, PublishAction, PurgeAction, -RemoveAction, ScanAction, SetupAction, UnlinkAction, UpdateAction, -InstallAutoinstallerAction, UpdateAutoinstallerAction, -UpdateCloudCredentialsAction, UpgradeInteractiveAction, -VersionAction, AlertAction, BridgePackageAction, LinkPackageAction -``` - -After these, `_populateScriptActions()` (lines 360-379) loads the repo's own `common/config/rush/command-line.json` file and registers its commands. If `_autocreateBuildCommand` is `false` (a plugin already defined `build`), the `doNotIncludeDefaultBuildCommands` flag is passed to `CommandLineConfiguration.loadFromFileOrDefault()`. - -### Plugin Command Registration - -At lines 381-416, `_addCommandLineConfigActions()` iterates over each command in the `CommandLineConfiguration` and dispatches to: -- `_addGlobalScriptAction()` (lines 434-459) for `global` commands -- `_addPhasedCommandLineConfigAction()` (lines 462-492) for `phased` commands - -Each method constructs the appropriate action class (`GlobalScriptAction` or `PhasedScriptAction`) and registers it via `this.addAction()`. - ---- - -## 3. Plugin Lifecycle: From Discovery to Execution - -### 3a. How Rush Knows Which Plugins to Load - -**User-configured plugins** are declared in `common/config/rush/rush-plugins.json`, governed by the schema at `/workspaces/rushstack/libraries/rush-lib/src/schemas/rush-plugins.schema.json`. - -The `RushPluginsConfiguration` class at `/workspaces/rushstack/libraries/rush-lib/src/api/RushPluginsConfiguration.ts:24-41` loads this file. Each plugin entry requires: -- `packageName` -- the NPM package name -- `pluginName` -- the specific plugin name within the package -- `autoinstallerName` -- which autoinstaller manages the plugin's dependencies - -This configuration is read by `RushConfiguration` at `/workspaces/rushstack/libraries/rush-lib/src/api/RushConfiguration.ts:674-678`: -```typescript -const rushPluginsConfigFilename = path.join(this.commonRushConfigFolder, RushConstants.rushPluginsConfigFilename); -this._rushPluginsConfiguration = new RushPluginsConfiguration(rushPluginsConfigFilename); -``` - -**Built-in plugins** are discovered by the `PluginManager` constructor at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/PluginManager.ts:62-98`. It calls `tryAddBuiltInPlugin()` for each known built-in plugin name, checking if the package exists as a dependency of `@microsoft/rush-lib`: -- `rush-amazon-s3-build-cache-plugin` -- `rush-azure-storage-build-cache-plugin` -- `rush-http-build-cache-plugin` -- `rush-azure-interactive-auth-plugin` (secondary plugin in the azure storage package) - -### 3b. How Rush Resolves the Plugin Package - -**Built-in plugins** are resolved via `Import.resolvePackage()` relative to rush-lib's own `__dirname` at `PluginManager.ts:72-77`. The resolved folder path is stored in the `IBuiltInPluginConfiguration.pluginPackageFolder` field. - -The `BuiltInPluginLoader` class at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/PluginLoader/BuiltInPluginLoader.ts:18-25` simply uses `pluginConfiguration.pluginPackageFolder` as its `packageFolder`. - -**Autoinstaller plugins** are resolved by `AutoinstallerPluginLoader` at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/PluginLoader/AutoinstallerPluginLoader.ts:38-48`. The `packageFolder` is computed as: -``` -/node_modules/ -``` -For example: `common/autoinstallers/my-plugins/node_modules/@scope/my-plugin`. - -The autoinstaller creates an `Autoinstaller` instance (line 40-45) which can be prepared (i.e., `npm install`/`pnpm install` run) before the plugin is loaded. - -### 3c. How Rush Reads the Plugin Manifest - -Every plugin package must contain a `rush-plugin-manifest.json` file (constant `RushConstants.rushPluginManifestFilename`). The manifest schema is at `/workspaces/rushstack/libraries/rush-lib/src/schemas/rush-plugin-manifest.schema.json`. - -The `PluginLoaderBase._getRushPluginManifest()` method at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/PluginLoader/PluginLoaderBase.ts:200-229` loads and validates this manifest. It finds the specific plugin entry matching `this.pluginName` from the manifest's `plugins` array. The manifest entry (`IRushPluginManifest` at lines 23-30) contains: -- `pluginName` (required) -- `description` (required) -- `entryPoint` (optional) -- path to the JS module exporting the plugin class -- `optionsSchema` (optional) -- path to a JSON schema for plugin options -- `associatedCommands` (optional) -- array of command names; the plugin is only loaded when one of these commands runs -- `commandLineJsonFilePath` (optional) -- path to a `command-line.json` file defining additional commands - -For **autoinstaller plugins**, the manifest is read from a cached location (the `rush-plugins` store folder) rather than from `node_modules` directly. `AutoinstallerPluginLoader._getManifestPath()` at `AutoinstallerPluginLoader.ts:150-156` returns: -``` -/rush-plugins//rush-plugin-manifest.json -``` - -This cached manifest is populated during `rush update` by `AutoinstallerPluginLoader.update()` at lines 58-112, which copies the manifest from the package's `node_modules` location to the store. - -### 3d. How Plugin Commands Are Discovered (Without Instantiating the Plugin) - -Plugin commands are discovered **before** the plugin is instantiated. The `PluginManager.tryGetCustomCommandLineConfigurationInfos()` method at `PluginManager.ts:184-197` iterates over all **autoinstaller plugin loaders** and calls `pluginLoader.getCommandLineConfiguration()`. - -`PluginLoaderBase.getCommandLineConfiguration()` at `PluginLoaderBase.ts:86-105`: -1. Reads `commandLineJsonFilePath` from the plugin manifest -2. If present, resolves it relative to the `packageFolder` -3. Calls `CommandLineConfiguration.tryLoadFromFile()` to parse and validate it -4. Prepends additional PATH folders (the plugin package's `node_modules/.bin`) to the configuration -5. Sets `shellCommandTokenContext` with the plugin's `packageFolder` for token expansion - -This means a plugin can define commands via its `command-line.json` file **without even having an entry point**. The `entryPoint` field is optional. - -### 3e. How Rush Instantiates the Plugin - -Plugin instantiation happens in two phases, controlled by the `associatedCommands` manifest property: - -**Phase 1: Unassociated plugins** -- Loaded during `parser.executeAsync()` at `RushCommandLineParser.ts:235-237`: -```typescript -await this.pluginManager.tryInitializeUnassociatedPluginsAsync(); -``` - -`PluginManager.tryInitializeUnassociatedPluginsAsync()` at `PluginManager.ts:152-165`: -1. Filters plugin loaders to those **without** `associatedCommands` in their manifest (`_getUnassociatedPluginLoaders` at lines 213-219) -2. Prepares autoinstallers (runs `npm install` if needed) -3. Calls `_initializePlugins()` for both built-in and autoinstaller loaders - -**Phase 2: Associated plugins** -- Loaded when a specific command executes, triggered by `BaseRushAction.onExecuteAsync()` at `/workspaces/rushstack/libraries/rush-lib/src/cli/actions/BaseRushAction.ts:127-129`: -```typescript -await this.parser.pluginManager.tryInitializeAssociatedCommandPluginsAsync(this.actionName); -``` - -`PluginManager.tryInitializeAssociatedCommandPluginsAsync()` at `PluginManager.ts:167-182` filters to plugins whose `associatedCommands` includes the current command name. - -The actual loading happens in `_initializePlugins()` at `PluginManager.ts:199-211`: -1. Checks for duplicate plugin names (line 202-203) -2. Calls `pluginLoader.load()` -- this returns the plugin instance -3. Adds the name to `_loadedPluginNames` to prevent re-loading -4. Calls `_applyPlugin(plugin, pluginName)` if the plugin was loaded - -### 3f. Plugin Loading Internals - -`PluginLoaderBase.load()` at `PluginLoaderBase.ts:70-80`: -1. Calls `_resolvePlugin()` (lines 151-164) which reads the `entryPoint` from the manifest and resolves it to an absolute path within the `packageFolder`. Returns `undefined` if no entry point. -2. Calls `_getPluginOptions()` (lines 166-185) which loads the options JSON from `/.json` and validates against the plugin's `optionsSchema` if present. -3. Calls `RushSdk.ensureInitialized()` (at `RushSdk.ts:12-22`) which sets `global.___rush___rushLibModule` so plugins using `@rushstack/rush-sdk` can access the same rush-lib instance. -4. Calls `_loadAndValidatePluginPackage()` (lines 123-149) which: - - `require()`s the resolved path - - Handles both default exports and direct exports - - Instantiates the plugin class with the loaded options: `new pluginPackage(options)` - - Validates that the instance has an `apply` method - -### 3g. How the Plugin's `apply()` Method Works - -`PluginManager._applyPlugin()` at `PluginManager.ts:230-236`: -```typescript -plugin.apply(this._rushSession, this._rushConfiguration); -``` - -The `IRushPlugin` interface at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/IRushPlugin.ts:10-12`: -```typescript -export interface IRushPlugin { - apply(rushSession: RushSession, rushConfiguration: RushConfiguration): void; -} -``` - -Plugins use the `rushSession.hooks` object (a `RushLifecycleHooks` instance) to tap into lifecycle events.

The resulting `CommandLineParameter` instance is stored in the `customParameters` map keyed by its `IParameterJson` definition. - -4. **In `PhasedScriptAction` constructor** (`PhasedScriptAction.ts:334`): After `defineScriptParameters()`, calls `associateParametersByPhase()` to link `CommandLineParameter` instances to their respective `IPhase` objects. - -### Phase-Parameter Association - -`associateParametersByPhase()` at `/workspaces/rushstack/libraries/rush-lib/src/cli/parsing/associateParametersByPhase.ts:17-32`: -- Iterates each `(IParameterJson, CommandLineParameter)` pair -- For each `associatedPhases` name on the parameter definition, finds the `IPhase` and adds the `CommandLineParameter` to `phase.associatedParameters` -- This allows per-phase parameter filtering during operation execution - -### Parameter Consumption - -- **Global commands**: `GlobalScriptAction.runAsync()` at `GlobalScriptAction.ts:133-153` iterates `this.customParameters.values()` and calls `tsCommandLineParameter.appendToArgList()` to build the argument string appended to `shellCommand`. -- **Phased commands**: `PhasedScriptAction.runAsync()` at `PhasedScriptAction.ts:487-490` builds a `customParametersByName` map from `this.customParameters` and passes it as `ICreateOperationsContext.customParameters`. These are then available to operation runners (e.g., `ShellOperationRunnerPlugin`) and plugins via `PhasedCommandHooks`. - ---- - -## 7. Differences Between Built-in Commands and Plugin-Provided Commands - -### Registration Timing - -| Aspect | Built-in Commands | Plugin Commands | -|--------|------------------|-----------------| -| **Registration** | `_populateActions()` in `RushCommandLineParser` constructor (line 179) | After `_populateActions()`, via `_addCommandLineConfigActions()` loop (lines 181-193) | -| **Source** | Hardcoded imports of action classes | `command-line.json` files from plugin packages or `common/config/rush/command-line.json` | -| **Class** | Direct subclasses of `BaseRushAction` or `BaseConfiglessRushAction` | `GlobalScriptAction` or `PhasedScriptAction` (both extend `BaseScriptAction`) | - -### Configuration Source - -- **Built-in commands**: Defined as TypeScript classes imported in `RushCommandLineParser.ts` lines 28-63. Their parameters are defined programmatically in each action's constructor. -- **Repo custom commands**: Defined in `common/config/rush/command-line.json`, loaded by `CommandLineConfiguration.loadFromFileOrDefault()` at line 374. -- **Plugin commands**: Defined in a `command-line.json` file inside the plugin package, referenced by `commandLineJsonFilePath` in `rush-plugin-manifest.json`, loaded by `PluginLoaderBase.getCommandLineConfiguration()` at line 86. - -### Name Conflict Handling - -At `_addCommandLineConfigAction()` (line 392-397), if a command name already exists (from a built-in or previously registered plugin), an error is thrown. Plugin commands are registered **after** built-in commands and **after** repo custom commands, so they cannot shadow existing names. - -### The `build` and `rebuild` Special Cases - -- If no `build` command is defined anywhere (not by plugins, not by `command-line.json`), a default `build` command is auto-created from `DEFAULT_BUILD_COMMAND_JSON` at `CommandLineConfiguration.ts:147-163`. -- Similarly, if `build` exists but `rebuild` does not, a default `rebuild` is synthesized at lines 461-481. -- The `_autocreateBuildCommand` flag at `RushCommandLineParser.ts:172-177` prevents the default build command from being created if any plugin already defines one. -- `build` and `rebuild` cannot be `global` commands (enforced at `CommandLineConfiguration.ts:427-432` and `RushCommandLineParser.ts:438-447`). - -### Bulk-to-Phased Translation - -Bulk commands are a legacy concept. `CommandLineConfiguration._translateBulkCommandToPhasedCommand()` at `CommandLineConfiguration.ts:707-746` converts them: -1. Creates a synthetic `IPhase` with the same name as the bulk command (line 708-721) -2. If `ignoreDependencyOrder` is not set, adds a self-upstream dependency (lines 723-725) -3. Registers the synthetic phase in `this.phases` and `_syntheticPhasesByTranslatedBulkCommandName` (lines 727-728) -4. Returns an `IPhasedCommandConfig` with `isSynthetic: true` (line 735) - -### Plugin Error Handling - -Plugin loading errors are **deferred** rather than immediately fatal. They are stored in `PluginManager.error` (line 42, 118-120) and only thrown when a command actually executes, via `BaseRushAction._throwPluginErrorIfNeed()` at `BaseRushAction.ts:148-166`. The commands `update`, `init-autoinstaller`, `update-autoinstaller`, and `setup` skip this check (line 160) since they are used to fix plugin installation problems. - -### Lifecycle Hooks Available to Plugins - -The `RushSession.hooks` property provides `RushLifecycleHooks` at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/RushLifeCycle.ts:53-114`: -- `initialize` -- before any Rush command executes -- `runAnyGlobalCustomCommand` -- before any global custom command -- `runGlobalCustomCommand` -- HookMap keyed by command name -- `runAnyPhasedCommand` -- before any phased command -- `runPhasedCommand` -- HookMap keyed by command name -- `beforeInstall` / `afterInstall` -- around package manager invocation -- `flushTelemetry` -- for custom telemetry processing - -Additionally, `PhasedCommandHooks` at `/workspaces/rushstack/libraries/rush-lib/src/pluginFramework/PhasedCommandHooks.ts:146-216` provides operation-level hooks: -- `createOperations` -- waterfall hook to build the operation graph -- `beforeExecuteOperations` / `afterExecuteOperations` -- around operation execution -- `beforeExecuteOperation` / `afterExecuteOperation` -- per-operation hooks -- `createEnvironmentForOperation` -- define environment variables -- `onOperationStatusChanged` -- sync notification of status changes -- `shutdownAsync` -- cleanup for long-lived plugins -- `waitingForChanges` -- notification in watch mode -- `beforeLog` -- augment telemetry data - ---- - -## Data Flow Summary - -``` -rush.json - | - v -RushConfiguration - |-- loads common/config/rush/rush-plugins.json -> RushPluginsConfiguration - | (list of IRushPluginConfiguration) - | - v -RushCommandLineParser constructor - | - |-- creates PluginManager - | | - | |-- creates BuiltInPluginLoader[] (from rush-lib dependencies) - | | each resolves packageFolder via Import.resolvePackage() - | | - | |-- creates AutoinstallerPluginLoader[] (from rush-plugins.json) - | | each computes packageFolder = autoinstaller/node_modules/ - | | - | |-- tryGetCustomCommandLineConfigurationInfos() - | for each AutoinstallerPluginLoader: - | reads rush-plugin-manifest.json -> commandLineJsonFilePath - | loads and parses that command-line.json - | returns CommandLineConfiguration + PluginLoaderBase - | - |-- _populateActions() - | registers 25 hardcoded action classes - | then _populateScriptActions(): - | loads common/config/rush/command-line.json - | registers GlobalScriptAction / PhasedScriptAction for each command - | - |-- for each plugin CommandLineConfiguration: - | _addCommandLineConfigActions() - | for each command: - | _addCommandLineConfigAction() - | creates GlobalScriptAction or PhasedScriptAction - | registers via this.addAction() - | - v -parser.executeAsync() - | - |-- pluginManager.tryInitializeUnassociatedPluginsAsync() - | for plugins without associatedCommands: - | prepares autoinstallers - | pluginLoader.load() -> require() entry point -> new Plugin(options) - | plugin.apply(rushSession, rushConfiguration) -> taps hooks - | - |-- super.executeAsync() -> routes to matched CommandLineAction - | - v -BaseRushAction.onExecuteAsync() - | - |-- pluginManager.tryInitializeAssociatedCommandPluginsAsync(actionName) - | for plugins with matching associatedCommands: - | same load/apply flow as above - | - |-- rushSession.hooks.initialize.promise(this) - | - |-- action.runAsync() - (GlobalScriptAction or PhasedScriptAction) - fires command-specific hooks, executes shell command or operation graph -``` diff --git a/research/docs/2026-02-07-rush-plugin-architecture.md b/research/docs/2026-02-07-rush-plugin-architecture.md deleted file mode 100644 index 84963803023..00000000000 --- a/research/docs/2026-02-07-rush-plugin-architecture.md +++ /dev/null @@ -1,628 +0,0 @@ -# Rush Autoinstaller and Plugin Architecture - -## Overview - -Rush provides a plugin system that allows extending its CLI and build pipeline through two mechanisms: **built-in plugins** (bundled as dependencies of `@microsoft/rush-lib`) and **autoinstaller-based plugins** (installed on-demand via the autoinstaller system into `common/autoinstallers//` folders). Plugins implement the `IRushPlugin` interface and interact with Rush through a hook-based lifecycle system powered by the `tapable` library. The `@rushstack/rush-sdk` package acts as a shim that gives plugins access to Rush's own instance of `@microsoft/rush-lib` at runtime. - ---- - -## 1.

Testing Framework - -### Test Runner: Jest (via Heft) -- Jest integration is provided through `@rushstack/heft-jest-plugin` (`heft-plugins/heft-jest-plugin`) -- The plugin provides a shared config: `heft-plugins/heft-jest-plugin/includes/jest-shared.config.json` -- Test configuration is defined in `config/jest.config.json` within each project or rig -- Tests run during `_phase:test` which depends on `_phase:build` - -### Test Project Categories - -#### `build-tests/` (59 projects) -Integration and scenario tests for Rush Stack tools: -- **API Extractor tests**: `api-extractor-test-01` through `-05`, `api-extractor-scenarios`, `api-extractor-lib*-test`, `api-extractor-d-cts-test`, `api-extractor-d-mts-test` -- **API Documenter tests**: `api-documenter-test`, `api-documenter-scenarios` -- **Heft tests**: `heft-node-everything-test`, `heft-webpack4/5-everything-test`, `heft-rspack-everything-test`, `heft-typescript-v2/v3/v4-test`, `heft-sass-test`, `heft-swc-test`, `heft-copy-files-test`, `heft-jest-preset-test`, etc. -- **ESLint tests**: `eslint-7-test`, `eslint-7-7-test`, `eslint-7-11-test`, `eslint-8-test`, `eslint-9-test`, `eslint-bulk-suppressions-test*` -- **Webpack tests**: `heft-webpack4-everything-test`, `heft-webpack5-everything-test`, `localization-plugin-test-01/02/03`, `set-webpack-public-path-plugin-test` -- **Rush integration tests**: `rush-amazon-s3-build-cache-plugin-integration-test`, `rush-redis-cobuild-plugin-integration-test`, `rush-package-manager-integration-test` -- **Package extractor tests**: `package-extractor-test-01` through `-04` - -#### `build-tests-samples/` (14 projects) -Tutorial projects demonstrating Heft usage: -- `heft-node-basic-tutorial`, `heft-node-jest-tutorial`, `heft-node-rig-tutorial` -- `heft-webpack-basic-tutorial`, `heft-web-rig-app-tutorial`, `heft-web-rig-library-tutorial` -- `heft-storybook-v6/v9-react-tutorial*` -- `heft-serverless-stack-tutorial` -- `packlets-tutorial` - -#### `build-tests-subspace/` (4 projects) -Projects in a separate PNPM subspace: -- `rush-lib-test`, `rush-sdk-test` - Test Rush API consumption -- `typescript-newest-test`, `typescript-v4-test` - Test TypeScript version compatibility - ---- - -## 10. CI/CD and Automation - -### GitHub Actions CI (`.github/workflows/ci.yml`) -The CI pipeline runs on push to `main` and on pull requests. It uses Rush's build orchestration to run builds and tests across all projects. - -### GitHub Actions - Doc Tickets (`.github/workflows/file-doc-tickets.yml`) -Automated workflow for filing documentation tickets. - -### Pre-commit Hook: Prettier -- **Autoinstaller**: `common/autoinstallers/rush-prettier/` -- **Tool**: `pretty-quick` (v4.2.2) with `prettier` (v3.6.2) -- **Command**: `rush prettier` runs `pretty-quick --staged` -- **Config**: `.prettierrc.js` at repo root -- Invoked as a global Rush command via Git pre-commit hook - -### Git Hooks -- Located in `common/git-hooks/` -- Pre-commit hook invokes `rush prettier` for code formatting - -### API Extractor Reports -API Extractor runs as part of the build phase for published packages, generating: -- `.api.md` API report files (tracked in `common/reviews/api/`) -- `.d.ts` rollup files for package consumers -- Configured per-project via `config/api-extractor.json` - ---- - -## 11. Package Management - -### PNPM Configuration -- **Version**: pnpm 10.27.0 -- **Workspace protocol**: Projects reference each other via `workspace:*` -- **Subspaces**: One additional subspace (`build-tests-subspace`) for isolated dependency resolution -- **Injected dependencies**: Enabled via `usePnpmSyncForInjectedDependencies` experiment - -### Decoupled Local Dependencies -Several packages declare `decoupledLocalDependencies` in `rush.json` to break circular dependency chains. The most common pattern is decoupling `@rushstack/heft` from libraries that Heft itself depends on (like `@rushstack/node-core-library`, `@rushstack/terminal`, etc.). - -### Version Management -- **Lock-step versioning**: Rush core packages (`@microsoft/rush`, `@microsoft/rush-lib`, `@rushstack/rush-sdk`, and rush-plugins) share version 5.167.0 -- **Individual versioning**: All other packages version independently -- **Change management**: `rush change` command generates change files in `common/changes/` - ---- - -## 12. Development Workflow - -### Standard Developer Flow -``` -rush install # Install dependencies -rush build # Build all projects (phases: lite-build → build) -rush test # Build + test all projects (phases: lite-build → build → test) -rush start # Watch mode: build, then watch for changes -rush prettier # Format staged files -``` - -### Build Phase Flow -``` -_phase:lite-build → _phase:build → _phase:test -(simple builds) (main build) (Jest tests) -``` - -Each phase runs per-project according to the dependency graph. The `lite-build` phase handles simple builds that don't support CLI args. The `build` phase runs TypeScript compilation, linting, API Extractor, and bundling (via Heft plugins). The `test` phase runs Jest tests. - -### Project Build Configuration Stack -``` -Project package.json - ↓ -config/rig.json → Rig package (e.g., @rushstack/heft-node-rig) - ↓ -Rig profile (e.g., profiles/default/) - ↓ -config/heft.json → Heft plugins - ↓ -tsconfig.json → extends rig's tsconfig-base.json - ↓ -config/rush-project.json → Build cache settings -``` - ---- - -## 13.

Rush plugins extend monorepo operations (caching, serving, etc.). Heft plugins provide build task implementations (TypeScript compilation, testing, bundling). - -3. **Rig system**: Eliminates config file duplication by allowing projects to inherit build configurations from shared rig packages. Projects only need a `config/rig.json` to point to a rig. - -4. **Phased builds**: Rush's phased build system splits builds into discrete phases (`lite-build`, `build`, `test`) that can be independently cached and parallelized. - -5. **Lock-step versioning**: Rush-related packages (rush, rush-lib, rush-sdk, rush-plugins) share a single version number and are published together. - -6. **Decoupled dependencies**: Circular dependencies between Rush Stack packages are broken using `decoupledLocalDependencies`, where a package uses the last published version of a dependency instead of the local workspace version. - -7. **Subspaces**: The subspace feature allows different groups of projects to have independent PNPM lockfiles, useful for testing different dependency versions. - -### Interconnection Map - -``` -rush.json (monorepo config) -├── common/config/rush/command-line.json (phases & commands) -├── common/config/rush/build-cache.json (caching) -├── common/config/rush/subspaces.json (multi-lockfile) -├── common/config/rush/experiments.json (feature flags) -└── common/config/rush/version-policies.json (versioning) - -Per-project: -├── package.json (dependencies, scripts) -├── config/rig.json → rig package -├── config/heft.json (or inherited from rig) -│ ├── Phase: build -│ │ ├── Task: typescript (heft-typescript-plugin) -│ │ ├── Task: api-extractor (heft-api-extractor-plugin) -│ │ └── Task: webpack/rspack (heft-webpack5-plugin or heft-rspack-plugin) -│ ├── Phase: test -│ │ └── Task: jest (heft-jest-plugin) -│ └── Phase: lint -│ └── Task: lint (heft-lint-plugin) -├── tsconfig.json → extends rig tsconfig-base.json -├── config/api-extractor.json (API report config) -├── config/rush-project.json (build cache config) -└── eslint.config.js or .eslintrc.js -``` - ---- - -## Code References -- `rush.json:1-1599` - Complete monorepo project inventory and Rush configuration -- `common/config/rush/command-line.json:1-511` - Phased build system definition -- `common/config/rush/build-cache.json:1-145` - Build cache configuration -- `common/config/rush/experiments.json:1-120` - Experimental features -- `common/config/rush/subspaces.json:1-35` - Multi-lockfile configuration -- `common/config/rush/version-policies.json:1-109` - Version policy definitions -- `common/config/rush/rush-plugins.json:1-29` - Rush plugin configuration (currently empty) -- `apps/heft/src/cli/HeftCommandLineParser.ts` - Heft CLI entry point -- `apps/heft/src/pluginFramework/IHeftPlugin.ts` - Heft plugin interface -- `apps/heft/src/pluginFramework/HeftPluginHost.ts` - Plugin host with access request system -- `rigs/heft-node-rig/profiles/default/config/heft.json` - Node rig Heft configuration -- `rigs/heft-node-rig/profiles/default/tsconfig-base.json` - Node rig TypeScript base config -- `rigs/heft-web-rig/profiles/app/config/heft.json` - Web rig app Heft configuration -- `.github/workflows/ci.yml` - CI pipeline configuration - -## Open Questions -- Detailed CI pipeline steps and matrix configurations (requires deeper reading of ci.yml) -- Complete dependency graph visualization between all ~130 packages -- Specific autoinstaller configurations beyond rush-prettier -- Historical versioning patterns and release cadence diff --git a/research/docs/2026-02-07-upgrade-interactive-implementation.md b/research/docs/2026-02-07-upgrade-interactive-implementation.md deleted file mode 100644 index 05059ccd390..00000000000 --- a/research/docs/2026-02-07-upgrade-interactive-implementation.md +++ /dev/null @@ -1,788 +0,0 @@ -# `rush upgrade-interactive` -- Full Implementation Analysis - -**Date:** 2026-02-07 -**Codebase:** /workspaces/rushstack (rushstack monorepo) - ---- - -## Overview - -The `rush upgrade-interactive` command provides an interactive terminal UI that lets a user -select a single Rush project, inspect which of its npm dependencies have newer versions -available, choose which ones to upgrade, update the relevant `package.json` files (optionally -propagating the change across the monorepo), and then run `rush update` to install the new -versions.

Key Architectural Patterns - -- **Dynamic Imports / Webpack Chunk Splitting:** Both `PackageJsonUpdater` and `InteractiveUpgrader` - are loaded via dynamic `import()` with webpack chunk name annotations - (`UpgradeInteractiveAction.ts:52-55`). Similarly, `DependencyAnalyzer` is dynamically imported - inside `doRushUpgradeAsync()` (`PackageJsonUpdater.ts:122-125`). This defers loading of these - modules until the command is actually invoked. - -- **Custom Prompt Registration:** The project selection uses Inquirer's prompt registration system, - overriding the `list` prompt type with `SearchListPrompt` (`InteractiveUpgrader.ts:46`). This - adds type-to-filter functionality without modifying Inquirer's source. - -- **Shared Updater Logic:** `PackageJsonUpdater` is shared between `rush add`, `rush remove`, and - `rush upgrade-interactive`. The upgrade path uses `doRushUpgradeAsync()` (which accepts - `INpmCheckPackageSummary[]`), while add/remove use `doRushUpdateAsync()` (which accepts - `IPackageForRushAdd[]` / `IPackageForRushRemove[]`). - -- **Monorepo Consistency Enforcement:** The `ensureConsistentVersions` policy and `--make-consistent` - flag determine whether upgrading a dependency in one project propagates to all other projects. - This uses `VersionMismatchFinder` to detect and resolve version mismatches. - -- **Singleton Registry Client:** `NpmRegistryClient` in `GetLatestFromRegistry.ts` uses a - module-level singleton pattern (lines 20-30) so all registry queries within a single command - invocation share the same client instance. - ---- - -## 12.

It spans two main packages: `@microsoft/rush-lib` (action class, interactive prompts, package.json update logic) and `@rushstack/npm-check-fork` (npm registry queries and version comparison). The feature uses `inquirer`, `cli-table`, `rxjs`, and `figures` as dependencies, all of which are bundled in rush-lib today. - -Rush has a well-established plugin architecture with two loading mechanisms: **built-in plugins** (bundled as `publishOnlyDependencies` of rush-lib, loaded via `BuiltInPluginLoader`) and **autoinstaller plugins** (user-configured in `rush-plugins.json`, loaded via `AutoinstallerPluginLoader`). Three build cache plugins are currently shipped as built-in plugins. Seven additional plugins exist as autoinstaller-based plugins. - -The `upgrade-interactive` feature is unique among the built-in actions because it does not interact with the hook system or the operation pipeline -- it is a self-contained interactive workflow. This makes it a candidate for extraction since it doesn't need deep integration with Rush internals beyond `RushConfiguration` and `PackageJsonUpdater`. - -## Detailed Findings - -### 1.

Plugin Command Registration - -Plugins can contribute CLI commands by: -1. Including `commandLineJsonFilePath` in their `rush-plugin-manifest.json` -2. The file uses the same format as `command-line.json` (commands, phases, parameters) -3. During `rush update`, `AutoinstallerPluginLoader.update()` copies this to the store at `/rush-plugins///command-line.json` -4. At parse time, `RushCommandLineParser` reads cached files via `pluginManager.tryGetCustomCommandLineConfigurationInfos()` -5. Commands are registered as `GlobalScriptAction` or `PhasedScriptAction` - -Currently, **no production plugin defines `commandLineJsonFilePath`** -- this is only used in test fixtures. All existing plugins interact via hooks rather than defining new CLI commands. - -### 5. Key Architectural Observations for Extraction - -#### What `upgrade-interactive` shares with other built-in commands - -- `PackageJsonUpdater` is shared with `rush add` and `rush remove` -- it cannot be moved into the plugin. The plugin would need to access this via `@rushstack/rush-sdk`. -- The `--variant` parameter uses a shared `VARIANT_PARAMETER` definition from `Variants.ts`. -- The action extends `BaseRushAction`, which provides `rushConfiguration`, plugin initialization, and lock file handling. - -#### What is unique to `upgrade-interactive` - -- `InteractiveUpgrader.ts` -- only used by this command -- `InteractiveUpgradeUI.ts` -- only used by this command -- `SearchListPrompt.ts` -- only used by this command -- `@rushstack/npm-check-fork` -- only used by this command -- Dependencies: `inquirer`, `cli-table`, `figures`, `rxjs` -- these could be moved out of rush-lib - -#### How the upgrade-interactive plugin would differ from existing plugins - -Existing plugins use **hooks** (`initialize`, `runPhasedCommand`, `afterInstall`, etc.) to extend Rush behavior. The `upgrade-interactive` command is a **standalone CLI action** -- it doesn't hook into any lifecycle events; it runs its own workflow. - -The plugin system currently supports adding commands via `commandLineJsonFilePath` in the manifest, which creates `GlobalScriptAction` or `PhasedScriptAction` that execute **shell commands**. The `upgrade-interactive` command is not a shell command -- it's an interactive TypeScript workflow that needs programmatic access to `RushConfiguration` and `PackageJsonUpdater`. - -This means the plugin would need to either: -- Define a `global` command in `command-line.json` pointing to a shell script/binary that uses `@rushstack/rush-sdk` for Rush API access -- Or implement a new pattern where the plugin's `apply()` method hooks into the `initialize` or command-specific hooks to intercept execution - -#### Autoinstaller system - -The autoinstaller system at [`libraries/rush-lib/src/logic/Autoinstaller.ts`](https://github.com/microsoft/rushstack/blob/d61ddd6d2652ce142803db3c73058c06415edaab/libraries/rush-lib/src/logic/Autoinstaller.ts) manages isolated dependency folders under `common/autoinstallers/`. It: -- Acquires file locks to prevent concurrent installs -- Checks `LastInstallFlag` for staleness -- Runs ` install --frozen-lockfile` when needed -- Global commands with `autoinstallerName` automatically get the autoinstaller's `node_modules/.bin` on PATH - -## Code References - -### upgrade-interactive implementation files -- `libraries/rush-lib/src/cli/actions/UpgradeInteractiveAction.ts` -- CLI action class (87 lines) -- `libraries/rush-lib/src/cli/RushCommandLineParser.ts:348` -- Registration point -- `libraries/rush-lib/src/logic/InteractiveUpgrader.ts` -- Interactive prompt orchestration (78 lines) -- `libraries/rush-lib/src/utilities/InteractiveUpgradeUI.ts` -- Checkbox dependency selection UI (222 lines) -- `libraries/rush-lib/src/utilities/prompts/SearchListPrompt.ts` -- Filterable list prompt (295 lines) -- `libraries/rush-lib/src/logic/PackageJsonUpdater.ts:120-244` -- `doRushUpgradeAsync()` (shared with `rush add`/`rush remove`) -- `libraries/rush-lib/src/logic/PackageJsonUpdaterTypes.ts` -- Shared types (88 lines) -- `libraries/npm-check-fork/` -- npm registry client and dependency comparison (7 source files) - -### Plugin infrastructure files -- `libraries/rush-lib/src/pluginFramework/IRushPlugin.ts:10-12` -- Plugin interface -- `libraries/rush-lib/src/pluginFramework/PluginManager.ts` -- Plugin orchestration -- `libraries/rush-lib/src/pluginFramework/PluginLoader/BuiltInPluginLoader.ts` -- Built-in plugin loading -- `libraries/rush-lib/src/pluginFramework/PluginLoader/AutoinstallerPluginLoader.ts` -- Autoinstaller plugin loading -- `libraries/rush-lib/src/pluginFramework/PluginLoader/PluginLoaderBase.ts` -- Base loader with manifest handling -- `libraries/rush-lib/src/pluginFramework/RushSession.ts` -- Session object with hooks and registration APIs -- `libraries/rush-lib/src/pluginFramework/RushLifeCycle.ts` -- Lifecycle hooks (8 hooks) -- `libraries/rush-lib/src/pluginFramework/PhasedCommandHooks.ts` -- Operation-level hooks (10 hooks) -- `libraries/rush-lib/src/schemas/rush-plugin-manifest.schema.json` -- Plugin manifest schema -- `libraries/rush-lib/src/schemas/rush-plugins.schema.json` -- User plugin config schema - -### Example plugins to model after -- `rush-plugins/rush-amazon-s3-build-cache-plugin/` -- Simplest built-in plugin pattern -- `rush-plugins/rush-serve-plugin/` -- Hooks phased commands, receives options -- `rush-plugins/rush-redis-cobuild-plugin/` -- Autoinstaller plugin with options -- `rush-plugins/rush-resolver-cache-plugin/` -- Plugin defined inline in index.ts - -## Architecture Documentation - -### Plugin loading flow (at Rush startup) -1. `RushCommandLineParser` constructor creates `PluginManager` -2. `PluginManager` registers built-in plugins (from rush-lib dependencies) and autoinstaller plugins (from `rush-plugins.json`) -3.

Existing plugin commands (via `commandLineJsonFilePath`) create `GlobalScriptAction` / `PhasedScriptAction` that execute shell commands. A new plugin would need to determine how to expose a programmatic TypeScript command -- either via the shell command + `@rushstack/rush-sdk` pattern, or via a new hook/registration mechanism. - -2. **Shared code boundary**: `PackageJsonUpdater.doRushUpgradeAsync()` is shared with `rush add` and `rush remove`. The plugin would need to either: (a) access `PackageJsonUpdater` via `@rushstack/rush-sdk`, (b) duplicate the relevant logic, or (c) expose it as a public API from rush-lib. - -3. **Built-in vs autoinstaller**: Should the plugin be a **built-in plugin** (bundled with rush-lib like the cache plugins) or a fully external **autoinstaller plugin**? Built-in would be simpler for users (no config needed) but wouldn't reduce rush-lib's dependency footprint. Autoinstaller would truly decouple the dependencies but require user configuration. - -4. **`@rushstack/npm-check-fork` disposition**: This package is currently only used by `upgrade-interactive`. It could either become a dependency of the new plugin package directly, or remain a standalone library that the plugin depends on. - -5. **Dependencies like `inquirer`, `cli-table`, `rxjs`, `figures`**: Are these used anywhere else in rush-lib? If they are exclusively for `upgrade-interactive`, they can be removed from rush-lib when the feature is extracted. This needs verification. - -6. **`SearchListPrompt` reusability**: The custom filterable list prompt is currently only used by `upgrade-interactive`. Could it be useful to other features, or should it move entirely into the plugin?
