Automatic codebase indexing for invisible context injection. Catalogs project structure, file types, entry points, dependencies, and test layout.
npx skills add majiayu000/claude-skill-registry --skill codebase-mapping-a5c-ai-babysitter --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 ## Overview Auto-indexes the project structure to build a comprehensive codebase map. This map is used for invisible context injection via the UserPromptSubmit hook, providing Claude with project awareness without explicit user prompting. ## Map Contents ### Project Structure - Directory tree with depth-limited enumeration - Key file identification (entry points, configs, lock files) ### File Type Distribution - Language breakdown (TypeScript, JavaScript, Python, etc.) - Framework detection (React, Next.js, Express, etc.) ### Entry Points - Main entry files (index, main, app) - CLI entry points - API route definitions ### Module Dependencies - Import graph analysis - Package boundary mapping - Circular dependency detection ### Test Layout - Test directory structure - Test file patterns and conventions - Test framework identification ## Context Injection The codebase map is injected as invisible context during UserPromptSubmit, providing: - Project type and framework awareness - Convention awareness for code generation - Dependency awareness for import suggestions - Test pattern awareness for test generation ## When to Use - Automatically at ClaudeKit session star

What does the codebase-mapping skill do?
Automatic codebase indexing for invisible context injection. Catalogs project structure, file types, entry points, dependencies, and test layout.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill codebase-mapping-a5c-ai-babysitter --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.
