TypeScript LSP Plugin for Cline CLI

A Cline CLI plugin that gives Cline a goto_definition tool powered by the TypeScript Language Service API.

Instead of relying on grep or text search, this plugin resolves symbol definitions through imports, re-exports, type aliases, barrel files, and more. It uses the same engine that powers "Go to Definition" in VS Code.

Install

cline plugin install https://github.com/cline/typescript-lsp-plugin.git

Verify it's loaded:

cline config  # check the plugin tab

How it works

Cline passes a file path and line number to the goto_definition tool. The plugin:

1. Walks up from the file to find the nearest tsconfig.json
2. Creates a TypeScript Language Service for that project
3. Scans the AST to find all identifiers on the given line
4. Resolves each identifier to its definition using getDefinitionAtPosition

The Language Service is cached per tsconfig, so repeated calls in the same project are fast.

TypeScript itself is resolved from the target project's node_modules at runtime, so this plugin has zero dependencies and uses whatever TS version the project is compiled with.

Example

Given a file with this import on line 4:

import { disposeAll, initVcr } from "@cline/shared"

The plugin resolves both symbols through the workspace package alias:

disposeAll -> packages/shared/src/dispose.ts:19
initVcr    -> packages/shared/src/vcr.ts:699

Plugin manifest

This repo follows the Cline plugin manifest format. The package.json declares plugin entry points in a cline field:

{
  "cline": {
    "plugins": [
      {
        "paths": ["./src/index.ts"],
        "capabilities": ["tools"]
      }
    ]
  }
}
