Guide on how to use external libraries in this project. Use when asked about installation, configuration, or API usage examples for any package referenced in app/package.json or the VSCode extension ecosystem.
Analyze and document the app/ codebase structure. Use when asked to understand the architecture, trace data flow, audit dependencies, or produce a structural overview of the VSCode extension source.
Review code changes, identify potential bugs, and suggest improvements. Use when reviewing pull requests or any code change in this repository.

Every piece of technical information must include a source reference:
| Information type | Required source |
|---|---|
| API usage / method signatures | Official documentation URL, or "see project usage at <file>:<line>" |
| Configuration options | File path where the config lives (e.g. app/eslint.config.mjs) |
| Version numbers | app/package.json (field: dependencies or devDependencies) |
| Installation commands | Official documentation or app/package.json scripts |
If a version cannot be confirmed from app/package.json, state: "version not pinned in this project — check the official release page."
All libraries used in this project are listed under devDependencies in app/package.json. There are no runtime dependencies (the extension uses only the built-in vscode module injected by VSCode at runtime).
| Package | Version | Role |
|---|---|---|
vscode (built-in) | ^1.120.0 (via engines.vscode) | VSCode Extension API — injected at runtime, not installed via npm |
@types/vscode | ^1.120.0 | TypeScript type definitions for the VSCode API |
@types/mocha | ^10.0.10 | TypeScript type definitions for Mocha test assertions |
@types/node | 22.x | Node.js built-in type definitions |
eslint | ^9.39.3 | JavaScript linter (flat config via eslint.config.mjs) |
@vscode/test-cli | ^0.0.12 | VSCode extension test runner (CLI wrapper) |
@vscode/test-electron | ^2.5.2 | Launches an Electron-based VSCode instance for integration tests |
Follow these steps in order:
Read app/package.json. Check both dependencies and devDependencies. State the version found, or note if it is absent.
Search the app/ source tree for imports or require calls referencing the library. If found:
app/src/providers/completionProvider.js:3)If the library is already installed (present in package.json), state that. If it needs to be added:
# devDependency (tooling, testing, types)
npm install --save-dev <package>
# runtime dependency (used at extension runtime)
npm install <package>
Note: for VSCode extensions, the vscode API itself is never installed — it is provided by the host.
If configuration is needed (e.g. ESLint, test runner), reference the actual config file in this project:
app/eslint.config.mjsapp/.vscode-test.mjsapp/jsconfig.jsonProvide a minimal code snippet. Prefer examples drawn from this project's source over generic documentation examples. Always cite the source:
app/src/views/servicesTreeProvider.js:42"Structure every library guide response as follows:
## <Library Name> (<version from package.json or "version TBD">)
**Role in this project**: <one sentence>
### Installation
<command or "already installed — see app/package.json">
(Source: <official docs URL or "app/package.json">)
### Configuration
<config snippet or "no configuration required">
(Source: <file path or official docs URL>)
### Usage Example
<code snippet>
(Source: <project file:line or official docs URL>)
### Notes
<any version-specific caveats, known issues, or links to changelog>
If the library is not present in the project and cannot be confirmed from official docs, state: "This information could not be confirmed from project files or official documentation. Please verify directly at ."
