description	Bootstrap AI-collaborative dev environment for existing codebases. TRIGGER when: user says "setup ai dev", "bootstrap project docs", "create CLAUDE.md", "generate project documentation", "setup development workflow", "initialize dev environment", "init project docs", "/ai-dev-setup", or mentions setting up AI assistant for a codebase, or wants CLAUDE.md created. Also trigger when user asks to "set up this project for AI" or "make this project AI-ready". DO NOT TRIGGER when: project is new/empty, or user only wants to explore without setup.

AI Development Environment Setup

Set up a complete AI-collaborative development environment for an existing codebase.

Usage

/ai-dev-setup [doc-directory-name]

Default doc directory: .docs. Override with argument, e.g., /ai-dev-setup docs.

Context Budget Rules

Load reference files on demand — not all at once. Each step specifies which file to load.

• Do NOT read all source files. Use directory listing + targeted sampling.
• Skip: vendor/, node_modules/, .git/, dist/, build/, pycache/, .venv/, target/, *.min.js, *.lock
• For large codebases (>50 source files): read 2-3 representative files per component, not every file.
• Keep generated docs concise — summaries, not code transcription.

---

Step 1: Environment Detection

Load: references/env-detection.md

1. Check project root config files → detect LANG, BUILD_CMD, TEST_CMD, LINT_CMD, TEST_COVER_CMD, RACE_FLAG, DOC_DIR
2. Check for existing: CLAUDE.md, .claude/skills/, DOC_DIR — handle per env-detection.md conflict rules

Report detection results. Wait for user confirmation.

---

Step 2: Codebase Scan

Context-efficient — do NOT read all source files.

1. List top-level structure (2 levels deep) to map components
2. Read dependency files: go.mod, package.json, requirements.txt, Cargo.toml, etc.
3. For each component directory: read 1-2 representative files to understand patterns
4. git log --oneline -20 for recent history
5. Grep for TODO/FIXME/HACK/XXX → collect file:line only, do not read surrounding code
6. Run TEST_COVER_CMD for coverage baseline (skip if no tests)

---

Step 3: Generate Documentation

Load: references/doc-templates.md

Create DOC_DIR/ and generate per templates. Rules:

• All content from actual code — never fabricate
• Mark unknowns as __% or [TBD]
• Each file max ~100 lines — link to code rather than quoting it

Files: README.md, ARCHITECTURE.md, CONVENTIONS.md, ROADMAP.md, TODO.md, TEST_PLAN.md, BACKLOG.md

---

Step 4: Create CLAUDE.md

# {Project Name}

## Build & Run
- Build: {BUILD_CMD}
- Run: [how to run]

## Testing
- Test: {TEST_CMD}
- Coverage: {TEST_COVER_CMD}

## Architecture
[One paragraph: purpose and structure]

## Dependencies
[External deps with purpose]

## Coding Conventions
See {DOC_DIR}/CONVENTIONS.md. Core principles:
1. [From actual code]
2. [From actual code]

## Documentation
- [Architecture](./{DOC_DIR}/ARCHITECTURE.md)
- [Conventions](./{DOC_DIR}/CONVENTIONS.md)
- [Roadmap](./{DOC_DIR}/ROADMAP.md)
- [TODO](./{DOC_DIR}/TODO.md)
- [Test Plan](./{DOC_DIR}/TEST_PLAN.md)
- [Backlog](./{DOC_DIR}/BACKLOG.md)

Append: templates/claude-md-appendix.md

If CLAUDE.md exists: show sections, offer augment (recommended) / backup+overwrite / cancel. Wait.

---

Step 5: Create Project Skills

Load: references/skill-templates.md

Generate into .claude/skills/: plan, dev, dev-resume, test, test-resume, sync-docs.

Replace: {DOC_DIR}, {TEST_CMD}, {LINT_CMD}, {TEST_COVER_CMD}, {RACE_FLAG}

If skills directory exists: list existing, warn overwrites, wait for confirmation.

---

Step 6: Verify & Report

• Commands in CLAUDE.md execute successfully
• Directory structure in ARCHITECTURE.md matches reality
• All DOC_DIR files non-empty, all SKILL.md files have valid frontmatter

## Setup Complete

Project: {name} | Language: {LANG} | Source files: {count}
Coverage baseline: {coverage}%
Issues: BUG {n} / OPT {n} / DEBT {n}

Generated:
- CLAUDE.md
- .claude/skills/{plan,dev,dev-resume,test,test-resume,sync-docs}/SKILL.md
- {DOC_DIR}/[README,ARCHITECTURE,CONVENTIONS,ROADMAP,TODO,TEST_PLAN,BACKLOG].md

Next: review CLAUDE.md → add to BACKLOG.md → /plan → /test

Error Handling

Situation	Action
Unknown language	Ask user for commands
No tests	Note 0% coverage, suggest /test
Command fails	Report, continue with available info
User rejects detection	Ask which commands to adjust, re-detect
User cancels	Clean up partial files, exit
