Use when a high-impact plan, migration or architecture claim needs a bounded adversarial challenge before commitment. Isolates claims from persuasion, attacks assumptions, reconciles doubts with evidence and emits proceed/hold/stop. NOT a finished-diff review (`review`/`code-review`), NOT SDD artifact consistency (`analyze`).
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
# decision-challenge — doubt with a stopping rule Use this immediately before a consequential commitment: an irreversible migration, a production-auth change, a costly architecture bet, a launch exception, or a plan whose confidence is higher than its evidence. The purpose is to find the decision-changing doubt, not to perform scepticism forever. This skill is read-only unless the user also asks to change the artifact. It emits a challenge record and a verdict. Finished code review stays with `../review/SKILL.md` or `../code-review/SKILL.md`; consistency across constitution/spec/plan/tasks stays with `../analyze/SKILL.md`. ## One bounded cycle ```text MATERIALIZE → ISOLATE → ATTACK → TEST → RECONCILE → VERDICT ``` ### 1. MATERIALIZE the decision Do not challenge a cloud of conversation. Write the concrete packet: - decision or claim being made; - artifact and exact revision it applies to; - constraints and invariants that must hold; - evidence the author relies on; - known unknowns; - cost of a false positive (unnecessary stop) and false negative (unsafe proceed). …

How to install
mdr add ericrisco/rsc-harness/decision-challenge@sha256:68a98fecdcffe476The line at the top of this page pins the label git:20261003.f0c84d6, 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.
