Lab Notebook · Production orchestration

The production agent hierarchy — Director → Manager → Worker → Tool

The orchestration pattern that turned 'everything is an agent' into production-grade software: a four-tier hierarchy that reached >90% test coverage in 2025 and hardened, in 2026, into a deterministic planner grounding plans in 200+ real agent packs. This is the engine behind our commercial builds — the deep report is protected.

Honest evaluation

Proven

The Director → Manager → Worker → Tool hierarchy is measured, not just claimed: >90% test coverage at production form, 219 planner/executor tests, and it is live and load-bearing in commercial work.

Runnable proof — see it work

What we learned — a preview

The honest edges are open even when the engine is not. The full report — what it was, what we built, and the measured internals — is protected.

  • The deterministic planner grounds in real on-disk agent packs; a subset are execution-proven, and that ratio is tracked honestly rather than rounded up.
  • The right abstraction was found empirically, after cheaper agent structures were tried and discarded.
  • Commercial specifics are deliberately withheld — this report describes the pattern, not the client engagements it runs.
Protected report

The deep body of “The production agent hierarchy — Director → Manager → Worker → Tool” is behind access.

We open the demos, the specs, and the method; we protect the engines, the model internals, and anything that touches commercial, safety-critical work. This report describes an engine — so its details are gated, and no client, company, or project is named. Members can read it in full; if you have a genuine reason to see it, tell us who you are and why.
