Aider Auto-Lint and Test

Configures Aider to automatically run Python linting and testing after making code changes, ensuring code quality and catching issues early.

What This Does

This skill configures Aider with:

**Model**: Uses Claude Sonnet for code generation

**Auto-linting**: Runs `ruff check --fix` and `ruff format` on Python files after changes

**Auto-testing**: Runs `pytest -vv` after changes to verify nothing broke

**Git ignore management**: Uses global git ignore file instead of per-repo

When this skill is active, follow these behaviors:

1. **Use Claude Sonnet model** for all code generation and modifications

2. **After any Python file changes**:

- Automatically run `ruff check --fix` to fix linting issues

- Automatically run `ruff format` to format code

- If lint fixes are applied, inform the user what was fixed

3. **After code changes complete**:

- Automatically run `uv run pytest -vv` to execute tests

- Report test results to the user

- If tests fail, offer to help fix the issues

4. **Git ignore handling**:

- Do not modify `.gitignore` files in repositories

- Assume user has global git ignore configured at `~/.config/git/ignore`

5. **Workflow**:

- Make requested code changes

- Run linting automatically (auto-lint: true)

- Run tests automatically (auto-test: true)

- Report results of both steps

- Iterate if issues found
