Codebase Analysis

Folder: .github/skills/tsh-codebase-analysing/
Used by: Architect, Business Analyst, Software Engineer

Provides a comprehensive 12-step process for analyzing an entire codebase, with support for monorepos.

12-Step Analysis Checklist​

  1. Repository structure — File organization, folder hierarchy.
  2. Dependencies — Package audit, outdated dependencies.
  3. Scripts — Build, test, lint, deploy scripts.
  4. High-level architecture — System components and interactions.
  5. Backend — API structure, data access, business logic.
  6. Frontend — Components, state management, routing.
  7. Infrastructure — Deployment config, CI/CD, environment setup.
  8. Third-party integrations — External services, APIs.
  9. Testing — Test coverage, patterns, gaps.
  10. Security — Security approach and vulnerabilities.
  11. Improvements — Prioritized improvement opportunities.
  12. Dead code & duplications — Unused code and duplication detection.

Key Capabilities​

  • Repository type identification (monorepo vs single system).
  • Architecture diagramming from code.
  • Dependency audit and outdated dependency detection.
  • Dead code and duplication detection.
  • Security approach rating.
  • Improvement prioritization (Critical / To be implemented / Nice to have).

Output​

A structured report (codebase-analysis.example.md template) covering all 12 steps. For monorepos, findings are organized per app/package.
