feat: codebase-analysis skill
8-phase methodology for extracting architectural conventions from
open source repositories:
1. Clone & Shape — measure repo dimensions
2. Import Hierarchy — find foundational packages
3. Interface Contracts — key abstractions
4. Error Handling & Quality Markers — TODOs, style
5. Unique Patterns — project-specific infrastructure
6. Git Archaeology — trace WHY decisions were made
7. PR Discussions — read the actual debates
8. Synthesis — produce analysis.md + conventions.md
Includes pattern-breaks reference (4 categories of why
conventions are violated, with real examples from CockroachDB,
Prometheus, Temporal, Ecto, Oban).
Output: Gitea repos named <project>-conventions.
