# verification-before-completion

Agent skill by Jesse Vincent (https://blog.fsck.com)

Fires the moment the agent is about to say something is done, fixed or passing. It has to run the verification and read the output first. If you have ever been told the build is green when it is not, this is the skill for that.

Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
