description: 'Jules is Google''s autonomous, asynchronous AI coding agent, developed inside Google Labs and powered by the
  Gemini family of models (currently Gemini 2.5 Pro on the free tier and Gemini 3 Pro on paid tiers). Jules connects to a
  user''s GitHub repositories, clones the target repo into a sandboxed Google Cloud VM, generates a multi-step plan, and then
  executes coding tasks such as bug fixes, refactors, dependency bumps, test authoring, and small feature builds, ultimately
  opening a pull request for human review. Jules ships three surfaces beyond the web app at jules.google.com: a documented
  REST API in alpha at jules.googleapis.com/v1alpha (Sources, Sessions, Activities) authenticated via X-Goog-Api-Key, a lightweight
  CLI called Jules Tools installable via npm, and a Gemini CLI extension that exposes Jules as a /jules slash command. Access
  is gated to Google account holders and the API is experimental. Jules is sold as part of the Google AI subscription bundles,
  with a free introductory plan (15 tasks/day, 3 concurrent), Google AI Pro at $19.99/month (100 tasks/day, 15 concurrent,
  Gemini 3 Pro), and Google AI Ultra at $124.99/month (300 tasks/day, 60 concurrent, priority Gemini 3 Pro access).'

  description: Alpha REST API for Google's Jules autonomous coding agent. Exposes Sources (connected GitHub repositories),
    Sessions (units of work against a source with a prompt and optional plan-approval workflow), and Activities (per-session
    events such as plans, messages, and progress updates). Supports creating sessions, listing sources and sessions, approving
    plans, sending messages to the agent, and listing activities, with optional automationMode AUTO_CREATE_PR for automatic
    pull-request creation. Authenticated via the X-Goog-Api-Key HTTP header; API keys are generated in the Jules web app Settings
    (maximum three active keys per user) and are auto-disabled if leaked.
