From 3e9cc03c6e325a869c3335dab6fa330ca4b70430 Mon Sep 17 00:00:00 2001 From: bntvllnt <32437578+bntvllnt@users.noreply.github.com> Date: Wed, 11 Mar 2026 23:21:35 +0100 Subject: [PATCH 1/6] =?UTF-8?q?feat:=20full=20CLI=20parity=20with=20MCP=20?= =?UTF-8?q?=E2=80=94=2015=20commands,=20shared=20core,=20docs?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add 10 new CLI subcommands (dependents, modules, forces, dead-exports, groups, symbol, impact, rename, processes, clusters) giving the CLI full feature parity with all 15 MCP tools. Extract 8 compute functions into src/core/index.ts and refactor both MCP handlers and CLI to use the shared core — eliminating ~200 lines of duplicated logic. Add 22 integration tests for new compute functions. Update all docs (cli-reference, AGENTS.md, llms.txt, llms-full.txt).
