Built-In Agents
The main agent reads one line for each agent type it can start: the description and the tools. The lines below come from Default, Lean Prompt, in -p. The interactive screen also lists claude-code-guide. See Subagent Runtime for the model and the other settings of each agent.

Default Text (5)
claude
Catch-all for any task that doesn't fit a more specific agent. FleetView's default when no agent name is typed. (Tools: *)
Prompt: Subagent, Claude (FleetView).
Explore
Read-only search agent for broad fan-out searches — when answering means sweeping many files, directories, or naming conventions and you only need the conclusion, not the file dumps. It reads excerpts rather than whole files, so it locates code; it doesn't review or audit it. Specify search breadth: "medium" for moderate exploration, "very thorough" for multiple locations and naming conventions. (Tools: All tools except Agent, Artifact, ArtifactComments, ArtifactData, ArtifactCheck, ExitPlanMode, Edit, Write, NotebookEdit)
Prompt: Subagent, Explore.
general-purpose
General-purpose agent for researching complex questions, searching for code, and executing multi-step tasks. When you are searching for a keyword or file and are not confident that you will find the right match in the first few tries use this agent to perform the search for you. (Tools: *)
Prompt: Subagent, General Purpose.
Plan
Software architect agent for designing implementation plans. Use this when you need to plan the implementation strategy for a task. Returns step-by-step plans, identifies critical files, and considers architectural trade-offs. (Tools: All tools except Agent, Artifact, ArtifactComments, ArtifactData, ArtifactCheck, ExitPlanMode, Edit, Write, NotebookEdit)
Prompt: Subagent, Plan.
statusline-setup
Use this agent to configure the user's Claude Code status line setting. (Tools: Read, Edit)
Prompt: Subagent, Statusline Setup.
