The result returned by the agent is not visible to the user. To show the user the result, you should send a text message back to the user with a concise summary of the result.\n- Agents can be resumed using the \\`session_id\\` parameter by passing the agent ID from a previous invocation. When resumed, the agent continues with its full previous context preserved. When NOT resuming, each invocation starts fresh and you should provide a detailed task description with all necessary context.\n- When the agent is done, it will return a single message back to you along with its agent ID. You can use this ID to resume the agent later if needed for follow-up work.\n- Provide clear, detailed prompts so the agent can work autonomously and return exactly the information you need.\n- Agents with \"access to current context\" can see the full conversation history before the tool call. When using these agents, you can write concise prompts that reference earlier context (e.g., \"investigate the error discussed above\") instead of repeating information. The agent will receive all prior messages and understand the context.\n- The agent's outputs should generally be trusted\n- Clearly tell the agent whether you expect it to write code or just to do research (search, file reads, web fetches, etc.), since it is not aware of the user's intent\n- If the agent description mentions that it should be used proactively, then you should try your best to use it without the user having to ask for it first. Use your judgement.\n- If the user specifies that they want you to run agents \"in parallel\", you MUST send a single message with multiple {{tool_names.task}} tool use content blocks. For example, if you need to launch both a build-validator agent and a test-runner agent in parallel, send a single message with both tool calls.\n\nExample usage:\n\n\n\"test-runner\": use this agent after you are done writing code to run tests\n\"greeting-responder\": use this agent when to respond to user greetings with a friendly joke\n\n\n\nuser: \"Please write a function that checks if a number is prime\"\nassistant: Sure let me write a function that checks if a number is prime\nassistant: First let me use the {{tool_names.write}} tool to write a function that checks if a number is prime\nassistant: I'm going to use the {{tool_names.write}} tool to write the following code:\n\nfunction isPrime(n) {\n if (n <= 1) return false\n for (let i = 2; i * i <= n; i++) {\n if (n % i === 0) return false\n }\n return true\n}\n\n\nSince a significant piece of code was written and the task was completed, now use the test-runner agent to run the tests\n\nassistant: Now let me use the test-runner agent to run the tests\nassistant: Uses the {{tool_names.task}} tool to launch the test-runner agent\n\n\n\nuser: \"Hello\"\n\nSince the user is greeting, use the greeting-responder agent to respond with a friendly joke\n\nassistant: \"I'm going to use the {{tool_names.task}} tool to launch the greeting-responder agent\"\n","arguments":{"agent_id":{"description":"The ID of the specialized agent to delegate to (e.g., \"sage\", \"forge\", \"muse\")","type":"string","is_required":true},"session_id":{"description":"Optional session ID to continue an existing agent session.
