# LSP Code Navigation

Multi-language LSP client that manages per-language background daemons. Auto-detects the language from file extension and routes queries to the correct server. Each server lazy-starts on first use and idles out after 5 minutes of inactivity.

**Use this instead of grep/read when you need to:**
- Find where something is defined
- Find all usages of a symbol
- Get type signatures or docstrings
- List all classes/functions in a file
- Check for type errors before running code
- Search for a symbol across an entire workspace

## Supported Languages

| Rust | `rust-analyzer` | .rs | `rustup component add rust-analyzer` |
| Go | `gopls` | .go | `go install golang.org/x/tools/gopls@latest` |
| C/C++ | `clangd` | .c, .h, .cpp, .cc, .hpp | `apt install clangd` or `brew install llvm` |

Only install the servers you need. The skill auto-detects which are available and reports helpful install commands for missing ones.
