Turn repeated management failures into enforced COS or PL rules. Load ONLY after the owner has explicitly activated the cos role for this session and the COS core routes here. Never invoke directly.
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 — harvesting friction into law Before running these commands, set `PL_SKILL_DIR` to the absolute directory of the installed `pl` skill, in the same Bash call. Load only when the owner has explicitly activated the COS role for this session and the COS core routes a repeated management failure here. **Exclusive authority of this overlay: the pen over skill files and `LEARNING.md`** (the batch review only appends the decision-rights lines named in its Pass 1). No other part of the COS tree, and no PL, may edit them. PLs propose by card. **The decision-rights file is different.** `~/.config/sno/decision-rights.md` is the owner's. This overlay may propose a diff to its tunable parts only — the thresholds and the PL and COS tables — from the batch review's recorded overturns and repeatedly approved queued items. Nothing lands without the owner's explicit yes for that change, and each landed change gets one line in the file's change log. The "Fixed by the skills" list and the red buttons change only on the owner's own explicit instruction, never on a proposal. **Never edit the skill tree mid-journey.** Evolution runs through a retro pass. A running …

How to install
mdr add sno-ai/sno-station-skills/cos-evolve@sha256:1b5d3eea0bc477a3The line at the top of this page pins the label git:20261001.8e39faf, 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.
