Sub-Agents Documentation
Overview
Sub-agents are background agent processes spawned from a parent agent run. They execute in isolated sessions and report results back to the requesting chat channel upon completion.
Key Commands
The /subagents slash command manages sub-agent runs:
list: View all active sub-agentsstop: Terminate specific or all sub-agentslog: Access execution logs with optional filtersinfo: Display run metadata and session detailssend: Transmit messages to running sub-agents
Spawning Sub-Agents
The sessions_spawn tool initiates sub-agent runs with these parameters:
task(required): The work assignmentlabel,agentId,model,thinking: Optional configuration overridesrunTimeoutSeconds: Execution time limitcleanup: Archive behavior (deleteorkeep)
Design Principles
Sub-agents do not get session tools by default, maintaining security boundaries. They cannot spawn their own sub-agents, preventing cascade complexity. Each maintains separate token accounting for cost management.
Session Management
Sub-agent sessions use the format agent:<agentId>:subagent:<uuid>. Authentication resolves through the target agent's configuration, with main agent profiles available as fallbacks. Sessions auto-archive after 60 minutes by default.
Announce Mechanism
Upon completion, sub-agents report results through an announce step. These messages include:
- Status (success, error, timeout, unknown)
- Result summary from the announce step
- Error details and contextual notes
- Runtime metrics and token usage statistics
Tool Restrictions
By default, sub-agents cannot access session-specific tools like sessions_list, sessions_history, sessions_send, or sessions_spawn. Administrators can customize allowed tools through configuration.
Concurrency & Performance
Sub-agents operate on a dedicated queue lane with configurable maximum concurrent runs (default: 8). Each maintains independent context and resource usage for cost optimization on heavy workloads.
