What problem does it solve? When a task is implemented, someone must objectively determine whether the result actually matches the planned expectation. This Skill provides a disciplined validation workflow that compares expected versus observed behavior, records concrete evidence, and delivers a clear Pass, Fail, or Blocked verdict without drifting into re-implementation. ## Core Features & Use Cases - Expectation-to-Observation Comparison: Reads the plan expectation, acceptance conditions, and implementation result, then selects the smallest validation surface that proves the expected behavior. - Evidence Recording: Captures exact validation commands, observations, and limits so results are reproducible and auditable. - Gate-Based Validation: For experiments, records a gate disposition (Stop, Rework, Investigate, Next Gate Unlocked, Complete) so a failed prerequisite gate never unlocks a larger experiment. - Use Case: After an engineer implements a micro-task in a multi-agent delivery workflow, run this Skill to verify the result against the planner's expectation and produce a structured validation-result.md with feedback and residual risks for the planner's next-step decision. ## Quick Start Validate the latest implementation result against the planner's expectation and produce a validation-result.md using the provided template.
