pb-nested-orchestrator SKILL.md skillA
pb-nested-orchestrator from agentproto/ts is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Spawn a parent agent that spawns and supervises its own sub-agents, forming a two-level tree on the agentproto daemon. Trigger for delegation depth - 'agent that spawns sub-agents', 'two-level agent tree', 'let an agent orchestrate on its own'.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# pb-nested-orchestrator — an agent that spawns its own sub-agents
## Goal
Build a two-level tree: you spawn ONE parent; the parent spawns and
supervises its own children through a scoped orchestration gateway; you
inspect the whole tree from the root and tear it all down at the end.
## Golden rule
The nesting PARENT must be adapter `claude-code` or `claude-sdk`. A `hermes`
parent ignores the injected orchestration gateway (proven) and simply cannot
spawn. Children can be any adapter.
Prerequisites (reference by name): `ap-spawn-agent`, `ap-wait-fanin`,
`ap-lifecycle`, and the `drive-agents` group. Single-level supervision is
`pb-supervise-parallel-mission`.
## Steps
### 1. Spawn the parent as an orchestrator
```
agent_start({
adapter: 'claude-code',
cwd: '<ABSOLUTE host path>',
label: 'orch-parent',
orchestrator: true,
prompt: '<parent brief - see step 3>'
})
```
`orchestrator: true` mounts a scoped sub-gateway in the parent: a curated
tool subset — start/prompt/wait/poll/output + session_tree + subtree kill —
with a per-child scope token that is revoked when the parent exits.
### 2. Prove the mount

How to install
mdr add agentproto/ts/pb-nested-orchestrator@sha256:3c54833dc9517e62The line at the top of this page pins the label git:20260901.0259d5f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
