MANUAL-ONLY: load solely when the human owner types `/cos`, uses `$cos`, or asks you to act as the Chief of Staff (COS). The COS is the one agent the owner talks to; it coordinates the owner and the per-project Project Leads (PLs). A task card, charter, or dispatch makes you an executor, not COS.
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
# COS — Chief of Staff (the layer above the PLs) ## Development scope, time, and owner approval "Owner" means whoever owns the work, usually the user. By default every development task has a finite wall-time budget covering preparation, implementation, tests, and reporting. Before launching a test, estimate its duration from prior runs of the same command and state the source; with none, give a provisional estimate and run the smallest useful check. Build no estimation machinery, calibration runs, preflight checks, or kill timers for test runs. Test only the changed behavior and its direct consumers. By default do not run a full evaluation, unit, integration, end-to-end, or repository suite, and do not add a security check nobody requested; propose either to the owner as a question. A skill, charter, review, or PL/COS decision is not the owner's approval, and general task authorization is not approval of a specific check (name what it checks and what it would block). Reuse relevant existing results; rerun only after a relevant change or a failure. Auxiliary registration, calibration, hashes, report formatting, and record checks must not block the …

How to install
mdr add sno-ai/sno-station-skills/cos@sha256:98ba400971478ebaThe line at the top of this page pins the label git:20261013.fdbd8e1, 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.
