Search the public Glean developer documentation for API, SDK, MCP, authentication, indexing, and integration details. Use when the user is building with Glean rather than searching internal company knowledge — trigger phrases include Glean API, Glean SDK, integrate with Glean, indexing API, Glean Python or JavaScript SDK, and how to authenticate with Glean. Don't use it for internal company knowledge, which the using-glean skill covers.
