Analyze Repo

Purpose

Build a complete mental model of the project and write it to SESSION_STATE.md. This is the "repo memory reload" skill — it turns a cold start into a warm start.

Steps

1. Discover Structure

# Get top-level layout
ls -la
# Find key config files
ls package.json tsconfig.json pyproject.toml Cargo.toml go.mod 2>/dev/null
# Framework detection
cat package.json | grep -E '"next"|"react"|"vue"|"express"|"fastapi"|"django"' 2>/dev/null

2. Read Key Config Files

Read (do not dump into conversation — just extract key info):

• package.json / pyproject.toml / Cargo.toml — dependencies and scripts
• .env.example — what environment variables are needed
• Existing CLAUDE.md if present — don't overwrite it, extend it

3. Map the Codebase

Use the explorer sub-agent to explore large codebases:

Use the explorer agent to: map the top 3 levels of directory structure and identify what each major directory contains

For smaller repos, read directly.

4. Identify Key Patterns

• Auth pattern (JWT, session, OAuth?)
• Database access pattern (ORM, raw SQL, query builder?)
• API style (REST, GraphQL, tRPC?)
• State management (if frontend)
• Test setup (unit? integration? e2e?)

5. Find Existing Scripts

cat package.json | python3 -c "import sys,json; d=json.load(sys.stdin); [print(k,':',v) for k,v in d.get('scripts',{}).items()]" 2>/dev/null

6. Write SESSION_STATE.md

Write a clean, structured summary:

# Session State
*Analyzed: [date]*

## Project
- **Name**: [name]
- **Stack**: [e.g., Next.js 14 + Supabase + Tailwind + TypeScript]
- **Package Manager**: [npm/pnpm/yarn]

## Key Commands
- Dev: `[command]`
- Test: `[command]`
- Build: `[command]`
- Lint: `[command]`

## Directory Map
- `/src/app` — Next.js App Router pages
- `/src/components` — Reusable UI components
- `/src/lib` — Utilities and helpers
- `/api` — API routes
- `/tests` — Test files

## Architecture Notes
[Key architectural decisions, patterns, and things Claude needs to know]

## Active Work
[What was being worked on — if any TODO.md or recent commits indicate this]

## Agents Available
[List the .claude/agents/ files found]

## Skills Available  
[List the .claude/skills/ directories found]

7. Report to User

Print a short 5-line summary:

• Stack detected
• Key commands found
• Number of agents/skills configured
• Anything unexpected or worth noting
• "SESSION_STATE.md updated. Ready to work."

Final Step — Surface Tips

After the analysis is complete, call the tips skill to show 2-3 relevant tips:

Skill("tips")

When calling from analyze-repo context:

• Show only 2-3 tips (not 5)
• Prioritize based on what the analysis revealed:
• Large files found → tip about targeted reads
• No tests found → tip about /test workflow
• No SESSION_STATE.md → tip about session continuity
• Many agents → tip about context window
• Label them: "Quick wins for this setup"
