codebase-mapping
Generate structured codebase maps with dependency graphs, file relationships, and architectural patterns. Use when exploring unfamiliar codebases or documenting project structure.
npx skills add majiayu000/claude-skill-registry --skill codebase-mapping-junior-frontend-dev-hi-u-ng --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Codebase Mapping Skill ## Purpose Produce consistent, structured documentation of codebase organization. ## When to Use - Starting work on unfamiliar project - Onboarding new team members - Documenting architecture decisions - Before major refactoring ## Output Template Use the template in [templates/structure-report.md](templates/structure-report.md) ## Mapping Process ### Step 1: Project Identification Identify project type from configuration files: - `package.json` → Node.js - `pyproject.toml` / `setup.py` → Python - `go.mod` → Go - `Cargo.toml` → Rust - `pom.xml` / `build.gradle` → Java ### Step 2: Structure Analysis Map directories to their purposes: - `src/` or `lib/` → Source code - `tests/` or `__tests__/` → Test files - `docs/` → Documentation - `scripts/` → Build/utility scripts - `config/` → Configuration files ### Step 3: Dependency Graph Create simplified dependency visualization: ``` Entry Point ├── Core Module A │ ├── Utility 1 │ └── Utility 2 ├── Core Module B │ └── External Lib └── Shared Components ``` ### Step 4: Key Files Identify and document: - Entry points (main.ts, index.js, app.py) - Configuration (tsconfig, eslint, etc.) - Environment handling - Build co

What does the codebase-mapping skill do?
Generate structured codebase maps with dependency graphs, file relationships, and architectural patterns. Use when exploring unfamiliar codebases or documenting project structure.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill codebase-mapping-junior-frontend-dev-hi-u-ng --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
