Pull Request Overview
This PR establishes a comprehensive CI/CD foundation for the Watchman project, adding automated quality assurance infrastructure to support the project's progression from 75% to 100% completion.
Purpose: Add GitHub Actions CI/CD pipeline, pre-commit hooks, and tool configurations to enforce code quality, security, and testing standards before the remaining ~1,500 LOC implementation.
Key Changes:
- GitHub Actions workflow with 4 parallel jobs (code quality, tests, Docker build, security scanning)
- Comprehensive tool configuration in pyproject.toml for Black, Ruff, isort, mypy, pytest, and Bandit
- Pre-commit hooks infrastructure with 10 hook categories for local enforcement
- Enhanced development dependencies with version-pinned quality tools and type stubs
- Extensive documentation covering setup, usage, and troubleshooting

The Bandit tests configuration uses a very long, hardcoded list of test IDs. This is fragile and difficult to maintain. Consider using a more declarative approach by specifying only the tests to skip rather than all tests to run. For example:
[tool.bandit]
exclude_dirs = ["/tests", "/scripts"]
skips = ["B101", "B201", "B301", "B601", "B602", "B603", "B604", "B605", "B606", "B607"]This is clearer and will automatically include any new tests added in future Bandit versions.

The needs: code-quality dependency on line 53 creates a serial execution where tests only run after code quality checks pass. This increases total CI time. Since both jobs are independent (both check code but in different ways), consider removing this dependency to allow parallel execution and faster feedback. If code quality fails, the overall CI will still fail, but developers get test results simultaneously.

The needs: test dependency on line 130 creates unnecessary serialization. The Docker build test is independent of test results and could run in parallel with the test job. This would reduce total CI time. Consider removing this dependency to improve CI performance.

The safety check on line 177 may fail in CI without proper authentication. Safety 3.0+ requires an API key for full functionality. Since this is set to continue-on-error: true, failures will be silent. Consider either:
- Adding a SAFETY_API_KEY secret to the repository
- Downgrading to Safety 2.x in requirements-dev.txt
- Removing this check if API key management is not desired
This aligns with the issue identified in requirements-dev.txt regarding Safety version.

The version constraint safety>=3.0.0 may be problematic. Safety 3.0+ introduced breaking changes and requires an API key for full functionality. The free tier has significant limitations. Consider using safety>=2.3.0,<3.0.0 to avoid potential CI failures or pinning to a specific 2.x version that works without authentication.

There was a problem hiding this comment.
The workflow introduced in this commit only triggers on pushes to main, develop, or claude/** and on PRs targeting main/develop. However, the repository’s current work happens on the work branch (this commit itself is on work), so developers pushing to the branch they actively collaborate on will never get any CI feedback. That defeats the purpose of adding this pipeline because regressions can land on work unchecked until someone happens to open a PR to main. Please include the work branch (or broaden the glob) in both the push and pull_request triggers so every change in this repo actually runs the new checks.
