Test a plan, decision, design, or just-finished work against its goal and agreed reference, using code, evidence, and safe commands, then recommend proceed, fix first, or stop, and name the smaller version if one exists. Returns a verdict, not design questions. --premortem assumes the goal failed and traces present weaknesses to that failure. --lens reviews through one fixed method (minimalist, failure-hunter, data-model, distributed, operability, boring-stack, agent-tooling, teacher…
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
# Challenge Input: `[plan/decision text, path, diff or ref range, or empty for the last proposal or work] [--premortem | --lens [<lens>] | --panel]` Rules for every mode, including referenced instructions: Do not retry a permission-denied action through another command, tool, path, or environment. Report the blocker. Ground factual claims in supplied evidence or results you observed in this session. - Take line numbers from numbered reads, not list-item numbers. Copy hashes, quotes, and errors exactly; verify stated counts. - Report another agent's findings only after its result returns and you check them. - Separate observations, inferences, and estimates. An outside fact without a checked source is unverified, not an estimate. - Scope all, only, and none to what you checked. A code-backed prediction is not an observed run. - Missing evidence: say what is unknown. Name a file or function instead of inventing a line number. - Before drafting, record each executed probe's full command and literal inputs and outputs. Build observed examples and execution counts from those records; label unexecuted examples as predictions. …

How to install
mdr add hugolopes45/hl-skills/hl-challenge@sha256:f081afd11b7b6743The line at the top of this page pins the label git:20261023.8a53261, 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.
