Map

Codebase 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 rg text-matching confusion (same name in comments/strings)

Execution

Run the generator script:

python3 ~/.claude/skills/map/scripts/symbol_map.py

The script will:

1. Detect project language (TypeScript/JavaScript/Python/Rust/Go)
2. Extract all exported symbols with their locations
3. 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:15 to check AuthProvider"
• "The formatDate function at src/utils/date.ts:42 needs modification"

No more grepping and guessing.
