What problem does it solve? After completing a coding or operational task, it is easy to miss bugs, incomplete requirements, or broken builds. This Skill adds an independent verification pass that reviews the session's work, runs builds and tests, and reports a clear PASS or FAIL verdict before you consider the task done. ## Core Features & Use Cases - Subagent-Based Verification: Spawns a general-purpose verifier subagent that independently reviews the conversation trace, inspects the environment, and validates outcomes rather than trusting claims. - Two-Phase Review: Always performs a trace review of what was asked versus what was done, and runs a code review phase (diff inspection, build, tests, linters) whenever code is involved. - Iterative Fix Loop: On a FAIL verdict, the identified issues are fixed and verification repeats up to three times until the work passes. - Use Case: After implementing an authentication fix, invoke the skill with a focus area like "auth logic and JWT handling" to have the verifier confirm the fix compiles, passes tests, and fully addresses the request. ## Quick Start Ask the assistant to run /check-work after finishing a task to verify the changes with an independent review.
