Plugins

tsgo-lsp

Fast TypeScript/JavaScript LSP backed by tsgo — Microsoft's native Go port of tsc. Drop-in replacement for the stock typescript-language-server, significantly faster on large codebases.

Includes a skill that nudges Claude to prefer LSP operations over Grep for symbol-level work (definitions, references, callers, implementations).

Install

/plugin marketplace add minhpg/claude-plugins
/plugin install tsgo-lsp@minhpg-claude-plugins

Then install the tsgo binary:

npm install -g @typescript/native-preview

Reload plugins and verify:

/reload-plugins

You should see 1 plugin LSP server in the output.

Recommended: add an always-on rule to CLAUDE.md

The bundled skill nudges Claude toward LSP when it judges the context relevant, but skills aren't sticky. For an always-on default, paste this into your ~/.claude/CLAUDE.md (personal) or project CLAUDE.md (team-shared):

## LSP over Grep for TS/JS symbols

When searching TypeScript/JavaScript code, default to the `LSP` tool — not `Grep` — for any symbol-level question: finding a definition, references, callers, implementations, or a type signature. Grep misses re-exports, type-only references, and import aliases that LSP resolves correctly.

Use `LSP workspaceSymbol` to locate a symbol by name, then chain `goToDefinition`, `findReferences`, `prepareCallHierarchy` → `incomingCalls`/`outgoingCalls`, `goToImplementation`, or `hover`. Use `documentSymbol` to list symbols in a single file.

Reach for Grep only when the target isn't a symbol: string literals, comments, TODOs, file paths, non-TS/JS files, or when you don't yet have a file+position to anchor on.

## LSP DECISION CHECK: Before every Grep call on TS/JS code, answer in
  one line:
    - Is the target a named symbol (function/type/var/component)? → LSP
    - Is it a string literal, comment, or TODO? → Grep
    - Is it a cross-file rename or reference hunt? → LSP findReferences
    - Am I trying to see a type's resolved shape? → LSP hover, not Read
  If you skip this check, you are violating rule.
