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
# System One decision models Use a model for a constrained judgment, not for permissions or side effects: ```text authorized state + trusted typed questions -> validated model answers -> deterministic policy -> act / wait / review / abstain -> observed outcome ``` Keep hard business rules, authority checks, thresholds, action execution, confirmation, and rollback in code or human control. A legal response shape does not imply a correct judgment; a high probability is not permission. ## Start here 1. Inspect the real application's state source, action boundary, tests, and deployment before changing it. Preserve existing deterministic/no-key behavior unless explicitly changing it is in scope. 2. Fill `templates/decision-contract.md`: trusted state, question IDs/types, allowed answers, unknown/review lane, side effects, owner, deadlines, and rollback. For tool control, also use `templates/action-control-contract.md`. New to this model class? Start with `references/worked-decision-pilot.md` to choose one bounded decision, then use `references/concepts-and-patterns.md` for primitive semantics and composition. …

How to install
mdr add magnus919/agent-skills/system-one@sha256:f42c069e05cd2b31The line at the top of this page pins the label v1.1, 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.
