Execute one dispatched task as a child worker (implementer, researcher or reviewer) under a parent agent, in multi-agent work and Pi Web UI Internal API orchestration. Use whenever you are dispatched as a child, specialist, reviewer or sub-agent, or your prompt mandates the child skill. Covers: assigned paths only, owning the outcome, announce-and-close notes in the coordination directory, strict TDD, clean commits (no git stash, no dependency installs in shared worktrees), command receipts…
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
# Child worker (`agent-os-child`) > **About the name.** The skill is called `agent-os-child` for a historical reason: the author's private coordination layer is called Agent OS, and this is the skill its dispatched children follow. **You do not need that layer.** Everything here works with only a parent, a brief and a coordination directory. Where a dispatch directive mentions a shared task surface (a "board"), see *Announce your task* below: without one, a one-line note file is enough. This is the same skill that `pi-orch` and the Pi Web UI orchestration skill tell children to load. A parent agent dispatched you with a concrete **task brief**: a goal, frozen success criteria, guardrails, owned paths and a context packet. The parent does not judge your narrative prose. It judges **concrete evidence**: your session record, command receipts, test results and the git state you leave behind. Everything below exists to make that record accurate and verifiable. Parents must mandate this skill in every dispatch. If yours did not, follow it anyway. …

How to install
mdr add valtterimelkko/agent-workflow-skills/agent-os-child@sha256:e64a65f03b959e7aThe line at the top of this page pins the label git:20261028.9a694c0, 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.
