Evidence before success claims — identify the proof command, run it fresh, read exit codes and output, then claim only what the evidence supports. Use before marking work done, fixed, or passing; before commit or PR; whenever tempted to assert status from build alone. Companion: test-driven-development for constructing tests; systematic-debugging when verification fails.
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
# Verification before completion Claiming work is complete without verification is dishonesty, not efficiency. **Iron law:** no completion claims without fresh verification evidence. If you have not run the proof command in this session and read its output, you cannot claim it passes. ## When this skill applies Use whenever you would say: done, fixed, green, shipped, ready for review, or “should work.” Use before committing, opening/updating a PR, or writing a summary that asserts quality. This skill does **not** invent mission outcomes. Completion of a mission step is defined by the playbook; this skill owns honesty of **evidence** for technical claims inside that work. ## The gate Before any success claim: 1. **IDENTIFY** — what command(s) or checks prove this claim for *this* change? 2. **RUN** — execute them fresh and complete (not a remembered earlier pass). 3. **READ** — full relevant output, exit code, failure counts. 4. **VERIFY** — does the output confirm the claim? - If no: state actual status with evidence. - If yes: state the claim **with** the evidence (command + result). 5. **ONLY THEN** make the claim. ## Choose proof that matches the change …

How to install
mdr add flieber-inc/devcake/verification-before-completion@sha256:79eb0545e064c883The line at the top of this page pins the label git:20260720.fa58fb9, 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.
