/auto-setup

Inspect the current project and propose configuration additions for the detected toolchain. Apply nothing without user approval at the end.

Step 1 — Detect

Check for these manifests in the project root and immediate subdirectories:

• package.json → Node.js / TypeScript
• pyproject.toml, setup.py, requirements.txt, Pipfile → Python
• Cargo.toml → Rust
• go.mod → Go
• pom.xml, build.gradle → JVM
• Multiple of the above → Monorepo / mixed

For each detected stack, identify:

• Package manager (npm/pnpm/yarn/poetry/pip/cargo/go/etc.)
• Lint command (e.g. npm run lint, ruff check, cargo clippy, golangci-lint run)
• Typecheck command (e.g. tsc --noEmit, mypy, none for Rust/Go which check at build)
• Test command (e.g. npm test, pytest, cargo test, go test ./...)

Read the actual scripts from package.json / pyproject.toml / etc. — don't assume names exist.

Step 2 — Propose CLAUDE.md additions

Show a diff block of what should be appended to the project's CLAUDE.md under a ## Project Toolchain heading:

## Project Toolchain

- **Stack:** <detected>
- **Lint:** `<command>`
- **Typecheck:** `<command>` (or "n/a — checked at build")
- **Test:** `<command>`
- **Run before commit:** `<lint && typecheck && test>`

Step 3 — Propose settings.json additions

If the project has .claude/settings.json, show a diff block adding permissions.allow entries for the detected commands so they don't prompt every time:

{
  "permissions": {
    "allow": [
      "Bash(<lint command>)",
      "Bash(<typecheck command>)",
      "Bash(<test command>)"
    ]
  }
}

Step 4 — Present and wait for approval

Output a single message containing:

1. Detected: the stack(s) found and where (paths to manifests).
2. Proposed CLAUDE.md addition: the markdown diff block from Step 2.
3. Proposed settings.json addition: the JSON diff block from Step 3.
4. Verification commands to run after applying (e.g. <lint command> should exit 0 on a clean tree).
5. Ask: "Apply both changes? (yes / only CLAUDE.md / only settings.json / no)"
