# Code Index Skill Use CTags to generate a searchable symbol index for quick navigation. ## When to use - Exploring an unfamiliar codebase - Locating definitions without opening full files - Mapping file structure before deep reads ## Scripts Scripts live in `scripts/codeindex/`: - `generate-index.sh [project-root]` - `lookup.sh <symbol-pattern> [project-root]` - `file-symbols.sh <file-path> [project-root]` ## Workflow 1. Generate the index for a project: ```bash ./scripts/codeindex/generate-index.sh /path/to/project ``` 2. Search symbols before reading files: ```bash ./scripts/codeindex/lookup.sh handleAuth /path/to/project ``` 3. Inspect a file's symbols: ```bash ./scripts/codeindex/file-symbols.sh src/api/auth.ts /path/to/project ``` 4. Regenerate after edits to keep the index fresh. ## Index location Indexes are written to `.codex/codeindex/` inside the target project: - `.codex/codeindex/tags` - `.codex/codeindex/files.txt`
