What problem does it solve? Agents often claim tasks are done without fresh evidence, collapse verification failures into success, or guess at fixes when user feedback is vague. This Skill enforces an evidence-first verification gate so no workflow task closes without validated results. ## Core Features & Use Cases - Evidence-Gated Closure: Blocks completion claims without fresh verification evidence and routes failures to changes_requested, blocked, or debugging states instead of done. - Correction Feedback Handling: Translates vague user corrections into new validation revisions, routing ambiguous drift back to socratic-clarification rather than guessing at fixes. - Analysis Confidence Gate: Requires analytical conclusions to state confidence level, evidence basis, alternative explanations, and falsifiers to prevent false certainty. - Use Case: After an implementation pass, run this Skill to verify results against the task brief, produce a BLUF-style report under 300 characters, create a checkpoint commit, and archive the task via the complete-verification command. ## Quick Start Verify the current task implementation against its brief and report whether it is ready for closure.
