A mob is Meerkat’s durable multi-agent unit. It turns several agent sessions into a coordinated team with stable member identities, role profiles, peer wiring, shared lifecycle events, and optional flows.

Why Mobs Exist

Single sessions are excellent for linear work. Mobs are for work that benefits from separate participants:
  • one lead plus several analysts
  • independent reviewers that compare findings
  • long-lived helper pools
  • incident rooms with specialized roles
  • browser-deployed teams packaged as mobpacks
Meerkat does not maintain a separate “sub-agent” substrate. Delegation and multi-agent orchestration compile to mob members.

The Objects

Stable Identity

Public mob APIs use AgentIdentity. Runtime bindings can rotate when a member respawns, moves, or reconnects, but the member’s public identity remains the key for status, wiring, work, and events.
This is why callers wire lead-1 to analyst-1 instead of wiring internal session IDs.

Host Vs Agent Surfaces

Mobs deliberately expose two kinds of interfaces: Agent tools let an agent create or coordinate helpers while it is working. Host APIs let applications create, supervise, inspect, and drive teams directly.

Runtime Modes

autonomous_host is the default when a member’s runtime mode is omitted. The member behaves like a long-lived peer and receives work through the mob runtime. turn_driven is explicit. Use it when the host wants tighter control over when the member starts turns.

Flows And Work

Flows are repeatable workflows over members. Work lanes are tracked, cancellable pieces of work sent to a mob or member. Use a flow when the workflow itself is reusable; use work submission when an application needs a handle for one unit of work.

Portability

Mobpacks package a mob definition and optional assets into a .mobpack file. They are the portable deployment shape for signed teams, repeatable CLI/service deployment, and browser-target builds.
