Meta loop

As explained in AI Agents in Action, Second Edition

A meta loop is an agent-controlled runtime loop in which an agent manages decisions, state, planning, delegation, and continuation across subtasks.

A meta loop is a layer-3 agentic loop in which an agent or agents control the decisions, state, and plan of internal or task-level processes. Unlike a task loop directed mainly by code, a meta loop reasons about delegation, progress, replanning, and completion. section 9.1 section 9.1.3

Use the subtype that matches how control is distributed:

  • Orchestration uses one delegating agent that maintains global state and the plan, calls specialized worker agents as tools, evaluates their results, and decides whether to delegate, replan, or finalize. section 9.3
  • Collaboration uses peer agents that share state, contribute, critique, refine one another’s work, and collectively decide when the goal is met. section 9.4

Research orchestration

A research orchestrator keeps an overall strategy, current focus, subtasks, and progress state. It delegates searching to a research worker and analysis to another worker, evaluates the findings, adds or reprioritizes subtasks when gaps appear, and finalizes only when the collective output satisfies the goal. section 9.3

How AI Agents in Action, Second Edition covers it

How deep it goes
Explains layer distinctions, orchestration and collaboration, typed state, delegation, evaluation, replanning, and termination; it builds on internal-loop concepts.
Examples
Uses research and analysis workers, typed orchestration decisions, and researcher-critic-synthesizer collaboration rounds.
What it assumes
Assumes familiarity with the internal agent loop and task loop while extending those ideas with agent-controlled planning and state.
What you can do after
Builds adaptive orchestration or collaboration loops that delegate work, revise plans, validate results, and stop on completion conditions.
How it connects
Connects agent loops with task loops, planning, state management, delegation, orchestration, collaboration, and shared-state consensus.
