Parallel specialist lanes let one Gateway route different chats or rooms to different agents, while keeping the user experience fast. The trick is to treat parallelism as a scarce-resource design problem, not just as “more agents”.

​
First principles

A specialist lane only improves throughput when it reduces contention for the real bottlenecks:
  • Session locks: only one run should mutate a given session at a time.
  • Global model capacity: all visible chat runs still share provider limits.
  • Tool capacity: shell, browser, network, and repository work can be slower than the model turn itself.
  • Context budget: long transcripts make every future turn slower and less focused.
  • Ownership ambiguity: duplicate agents doing the same job waste capacity.
OpenClaw already serializes runs per session and caps global parallelism through the command queue. Specialist lanes add policy on top: which agent owns which work, what stays in chat, and what becomes background work.

​
Phase 1: lane contracts + background heavy work

Give every lane a written contract in its workspace and system prompt:
  • Purpose: the work this lane owns.
  • Non-goals: work it should hand off instead of attempting.
  • Chat budget: quick answers stay in chat; long tasks should acknowledge briefly, then run in a background sub-agent or task.
  • Handoff rule: when another lane owns the work, say where it should go and provide a compact handoff summary.
  • Tool-risk rule: prefer the smallest tool surface that can do the job.
This is the cheapest phase and fixes most clogging: one coding job no longer turns the research lane into molasses, and each chat keeps its own context clean.

​
Phase 2: priority and concurrency controls

Tune queue and model capacity around the business value of each lane: 
{
  agents: {
    defaults: {
      maxConcurrent: 4,
      subagents: { maxConcurrent: 8 },
    },
  },
  messages: {
    queue: {
      mode: "collect",
      debounceMs: 1000,
      cap: 20,
      drop: "summarize",
    },
  },
}
Use direct/personal chats and production-ops agents for high-priority work. Let research, drafting, and batch coding move to background tasks when the system is busy.

​
Phase 3: coordinator / traffic controller

Add a small coordinator pattern once multiple lanes are active:
  • Track active lane tasks and owners.
  • Detect duplicate requests across groups.
  • Route handoff summaries between lanes.
  • Surface only blockers, completed results, and decisions the human must make.
Do not start here. A coordinator without lane contracts just coordinates chaos.

Minimal lane contract template

# Lane contract

## Owns

- <job this lane is responsible for>

## Does not own

- <work to hand off>

## Chat budget

- Answer quick questions directly.
- For multi-step, slow, or tool-heavy work: acknowledge briefly, spawn/background
  the work, then return the result when complete.

## Handoff

If another lane owns the request, reply with:

- target lane
- objective
- relevant context
- exact next action

## Tool posture

Use the smallest tool surface that can complete the task. Avoid broad shell or
network work unless this lane explicitly owns it.
