# claude-playground

A tiny zero-dependency Node.js todo CLI, used as a sandbox for trying Claude Code features.

## Commands
- `npm test` — run the test suite (built-in `node:test`, no install needed)
- `npm start -- add "something"` / `npm start -- ls` — run the CLI (data in `todos.json`, override with `TODO_FILE`)

## Conventions
- ES modules, Node >= 20, no third-party dependencies.
- `src/todo.js` holds pure functions; keep I/O in `load`/`save` and `src/cli.js`.
- Every behavior change gets a test in `test/`.
- Commit messages: short imperative subject line.

## Workflow (required)
Never commit, merge, or push to `main`. Only a human (Christian) merges into `main`.
1. Branch off an up-to-date `main` before any change: `git switch -c <type>/<short-name>` (e.g. `fix/duplicate-ids`, `docs/readme`).
2. Commit on that branch; run `npm test` before pushing.
3. Push the branch and open a PR against `main`.
4. Run `/code-review` on the PR branch.
5. Post the result as a PR comment that starts with either **Approved** or **Needs fixes**, followed by the findings. If it needs fixes, fix them on the same branch, push, and repeat steps 4–5.
6. Stop there. Do not merge the PR, even if approved — tell the human it's ready.
