- #9: standardize the test chain on stdlib unittest (nothing-to-install, which keeps M13's claims true and its planted bug intact). Aligned M5/M14/M16 prose, M14 lab/test_tasks.py, and ci/gitlab starters; ruff stays the only pip install. - #20: add venv / PEP 668 / which-python guidance to M20 (+ M14/M15 local installs); point MCP config at the venv's absolute python. - #21: replace M21 Part D's empty `git diff HEAD~1` with `git log -p` (no .gitignore added — device preserved). - #22: add a dependency-install step before M23's green baseline on a fresh clone. - #23: M24 reviewer/triage now tolerate code-fence-wrapped JSON (stdlib only); feature.patch trap untouched. - #28: fix M27 Part D CI snippet path (working-directory) and require the gate to target a varying candidate; swapped_model regression kept as the fixture.

Instructions for AI agents working on tasks-app
A tiny command-line task tracker. The point of this project is to be small enough to read in a minute but real enough to have more than one file. Keep it that way — don't grow it into a product.
Project layout
tasks.py— core logic (Task,TaskList). New behavior that isn't about the command line goes here.cli.py— the command-line front end. Argument parsing and printing only; it calls intotasks.py. Reads and writestasks.json.tasks.json— generated state. See "Don't touch" below.
Build and test commands
- Run the app:
python cli.py <command>(e.g.python cli.py list). - Run the tests:
python -m unittest - Do not claim a change works until you have actually run it. If tests exist, they must pass first.
Coding standards
- Python 3.10+ . Standard library only — no third-party packages without being asked.
- Type-hint public functions and methods. Match the existing dataclass style in
tasks.py. - Handle bad input gracefully (e.g. a non-numeric index) rather than letting a raw traceback escape.
Don't touch
- Never edit
tasks.jsonby hand. It is generated by the app; hand-editing it corrupts state. Read it if you need to, but change it only by running the CLI. - Don't reformat or rewrite files you aren't actively changing. Keep diffs small and focused.
House style
- Keep functions small and single-purpose. Prefer clarity over cleverness.
- Match the surrounding code's style; don't introduce a new pattern for something the project already does one way.
- When you add a command, wire it into
cli.py's dispatch and update the usage string.
