+
+## SKILLS
+
+### meta-skill-creator
+
+Create new skills with proper structure.
+
+```bash
+bun .claude/skills/meta-skill-creator/scripts/init-skill.ts <name> --path <dir>
+bun .claude/skills/meta-skill-creator/scripts/validate-skill.ts <folder>
+```
+
+### meta-agent-creator
+
+Create new agents for multi-agent orchestration.
+
+```bash
+bun .claude/skills/meta-agent-creator/scripts/init-agent.ts <name> --path <dir> --platform <platform>
+bun .claude/skills/meta-agent-creator/scripts/validate-agent.ts <file>
+```
+
+## CONVENTIONS
+
+### Command Format
+
+- Markdown files with frontmatter-style instruction blocks
+- Use `<command-instruction>` wrapper for main logic
+- Include examples for all usage patterns
+
+### Skill Structure
+
+```
+skill-name/
+├── SKILL.md          # Main doc (<500 lines)
+├── scripts/          # Automation scripts (TypeScript)
+├── references/       # Extended documentation
+└── assets/           # Templates, static files
+```
+
+### SKILL.md Requirements
+
+- Frontmatter: `name` (kebab-case), `description` (what + when)
+- Body: <500 lines, use references/ for overflow
+- No README.md, CHANGELOG.md, or redundant files
+
+## ANTI-PATTERNS
+
+- **Long SKILL.md** - Split to references/ if >500 lines
+- **Vague descriptions** - Include specific trigger contexts
+- **Untested scripts** - Run all scripts before packaging
+- **Generic agents** - Each agent needs single, clear purpose

+Labels PRs based on title prefix (e.g., `feat:` adds `feat` label).
+
+### auto-assign.yml
+
+Auto-assigns PR creator as assignee.
+
+## CONVENTIONS
+
+### Issue Title Format
+
+```
+<type>: <description>
+```

+
+### PR Title Format

+## ANTI-PATTERNS (THIS PROJECT)
+
+- **No `chore` type** - Use `config` instead (work is never unimportant)
+- **No npm/yarn** - pnpm only
+- **No README.md in skills** - Only SKILL.md per meta-skill-creator spec
+- **No generic "helper" agents** - Single responsibility per agent
+
+## NOTES
+
+- **Template repo**: This is a GitHub template - use "Use this template" button
+- **Under development**: External contributions not yet accepted
+- **Bilingual docs**: README.md + README.ko.md pattern
