What problem does it solve? Documentation drifts out of sync with the actual CLI behavior, commands, and examples it describes. This Skill catches factual errors in OpenSpec user docs before they reach readers by having an independent reviewer verify every claim against the repository source. ## Core Features & Use Cases - Fresh-context verification: Spawns a general-purpose subagent per section or claim list, so the reviewer has not watched the prose being written and cannot inherit the author's assumptions. - Command re-execution: Re-runs terminal commands from the docs, checks output blocks against real output, and validates example specs with openspec validate. - Style and structure checks: Flags duplicated canonical content, hype adjectives, vague claims, and violations of the docs tree README invariants and house writing rules. - Use Case: After drafting a new OpenSpec docs page, ask for a verification pass on a specific section; the reviewer reports findings ranked by severity with quoted lines, one-line fixes, and exactly how each fact was verified. ## Quick Start Ask the agent to verify the 'Getting Started' section of the OpenSpec docs page against the repository source.
