SKILL.md

The typescript-lsp plugin provides semantic code intelligence for TypeScript and JavaScript. Use LSP tools instead of grep/read when you need semantic accuracy - LSP understands TypeScript's type system, inheritance, interfaces, and symbol relationships.

| Find all callers of a function | findReferences | Grep for function name | | Get function/variable type | hover | Read file + parse | | Jump to definition | goToDefinition | Grep + Read | | Check type errors | getDiagnostics | Run tsc CLI | | View file structure | documentSymbol | Read entire file |

| Grep for symbol before rename | Text search misses aliased imports, re-exports | Use findReferences | | Read entire file for one type | Wastes context, slow | Use hover | | Run tsc after every change | Slow, external tool | Use getDiagnostics | | Grep to find definition | May find wrong match (same name, different module) | Use goToDefinition |
