Code Quality Automation

Automated detection of code quality issues in Elixir projects. These checks run automatically via hooks when files are written, and can be run on-demand for full project analysis.

RULES — Follow these with no exceptions

1. Duplicated functions must be extracted — when 2+ modules share >70% identical function implementations, create a shared module
2. Functions must stay below ABC complexity 30 — break complex functions into smaller helpers with single responsibilities
3. Unused private functions must be removed — dead code increases maintenance burden and confusion
4. Duplicated templates must become components — when 2+ HEEx files share >40% identical markup, extract to a function component
5. Run full analysis before major refactors — use run_analysis.sh to establish a baseline before and after
6. Address duplication before complexity — extracting shared code often reduces complexity as a side effect
7. Prefer composition over inheritance — extract shared functions into modules imported/used where needed, not into base modules
