Example: Asking Claude a Question

- id: claude
  tool: ANTHROPIC_INVOKE
  config:
    - name: version
      value: claude-3-7-sonnet-20250219
    - name: token
      value: "{{secrets.ANTHROPIC_API_KEY}}"
  input:
    - name: prompt
      value: What is the capital of France?

Example: Running a Claude Managed Agent

ANTHROPIC_AGENT runs a Claude Managed Agent that can read, write, and edit files and use web tools autonomously. Input files (up to 20, passed via files) are mounted under /workspace/inputs/ for the agent, and files the agent writes to /mnt/session/outputs/ are returned as result.files — each entry has content, filename, and fileType, shaped so it can be passed directly to a downstream OUTPUT_FILE step. The agent’s final text output is returned as result.content, along with stop_reason and timed_out.

Available models are claude-opus-4-7 (default), claude-sonnet-4-6, and claude-haiku-4-5-20251001. The timeout_sec input sets a hard wall-clock timeout in seconds (60–1800, default 600). If you bring your own Anthropic API key, you must also supply your own agent_id and environment_id in config; in that case the model is fixed on your Anthropic-side Agent and the model selector is ignored.

  tool: ANTHROPIC_AGENT
