About map
map is a codebase symbol-map generator for developers exploring or refactoring a project. It detects supported languages and records exported symbols with precise file and line locations.
Key features
- 01Detect TypeScript, JavaScript, Python, Rust, and Go
- 02Extract exported symbols
- 03Record file and line locations
- 04Generate a Markdown symbol map
Use cases
- 01Explore an unfamiliar codebase
- 02Locate symbols before refactoring
Install
Copy the command and run it in a terminal.

Details
From the project READMECodebase Symbol Map Generator
Generate a semantic symbol map showing where all exports, classes, functions, and interfaces are defined. This eliminates guessing with rg by providing precise file:line locations.
When to Use
- Starting work on an unfamiliar codebase
- Before large-scale refactoring
- When needing to understand code structure
- To avoid
rgtext-matching confusion (same name in comments/strings)
Execution
Run the generator script:
python3 ~/.claude/skills/map/scripts/symbol_map.py
The script will:
- Detect project language (TypeScript/JavaScript/Python/Rust/Go)
- Extract all exported symbols with their locations
- Generate a markdown map at
~/.claude/codebase-maps/{project}_symbols.md
Output Format
## Symbol Index by Type
### Classes
| Symbol | Location |
| -------------- | ------------------------- |
| `AuthProvider` | `src/auth/provider.ts:15` |
### Functions
| Symbol | Location |
| ------------ | ---------------------- |
| `formatDate` | `src/utils/date.ts:42` |
Usage After Generation
After running /map, use the symbol locations directly:
- "Read
src/auth/provider.ts:15to check AuthProvider" - "The
formatDatefunction atsrc/utils/date.ts:42needs modification"
No more grepping and guessing.
