Agent Pool
What the Agent Pool is
When AI Partner runs a complex goal, it can spawn multiple sub-agents to work in parallel. Each sub-agent is an independent execution context with its own task, tools, and ReAct loop.
The Agent Pool Monitor (sidebar → Agent Pool) gives you a live view of all sub-agents: how many are active, what each one is doing, and the option to cancel any individual agent or all of them.
Agent Pool limits
| Limit | Default |
|---|---|
| Agents running at once | 5 |
| How deep delegation can nest | 3 |
Depth means how many levels of delegation can nest. A goal spawns sub-agents (depth 1). Those sub-agents can themselves delegate further (depth 2). Depth 3 is the maximum — sub-sub-sub-agents cannot delegate further.

What each field means
| Field | Description |
|---|---|
| Active | Sub-agents currently running (counts toward the 5-agent limit) |
| Total spawned | All agents started since the current goal began |
| depth | How deep in the delegation chain this agent is (1 = direct child of the main executor) |
| role | The agent profile assigned to this sub-task |
| Task | What this agent was asked to do |
| Status | Running / Waiting for dependency / Completed / Failed |
| Parent | Which agent delegated to this one (depth 2+ only) |
Real-time updates
The panel updates itself — no refreshing. An agent appears as Running the moment it starts, and moves to Completed with its result, or its error, the moment it finishes.
Cancelling agents
Cancel one agent: click Stop (⏹) next to any running agent. It stops immediately, not at the end of its current step. Any files or partial results it already produced are kept — cancelling never throws away work that was already done.
Cancel all agents: click Cancel All at the top of the panel. This cancels the main goal and all sub-agents simultaneously.
Cancelling a sub-agent does not automatically cancel the parent goal. The parent goal may continue with the partial results from completed sub-agents, or it may escalate to you with an HITL prompt if a cancelled sub-task was required for goal completion.
When parallel agents help
The main executor decides whether to run agents in parallel based on the goal's task graph. Tasks with no dependencies run simultaneously:
Example goal:
Research OpenAI, Anthropic, and Google DeepMind:
their latest funding, key hires, and product announcements.
Write a comparison report.
What runs:
Main agent: decompose into 4 tasks
Task 1: Research OpenAI → Agent A (parallel)
Task 2: Research Anthropic → Agent B (parallel)
Task 3: Research DeepMind → Agent C (parallel)
[all three run simultaneously — ~45 seconds total instead of ~135 sequential]
Task 4: Write comparison report (depends on 1+2+3) → runs after all three complete
The Agent Pool Monitor shows all three research agents active at the same time.
When agents wait
If a sub-task depends on another, the waiting agent shows ⏳ Waiting for [parent task]. It starts automatically when the dependency completes — you don't need to do anything.
If a dependency fails, the waiting agent is marked ⏭ Skipped — it was never started because its prerequisite didn't complete.
