What problem does it solve? Starting work in an unfamiliar domain or codebase area often fails because of blind spots: decisions you didn't know existed, conventions you never saw, and failure modes invisible from the entry point. This Skill runs a structured blind spot pass before work begins so those gaps surface early instead of mid-implementation. ## Core Features & Use Cases - Calibrated gap analysis: Anchors on what the user already knows, then sweeps code paths, git history, prior PRs, and repo conventions for what would surprise them. - Categorized report: Groups findings into architecture-changing decisions, what good looks like, prior art and potholes, and vocabulary needed to prompt precisely. - Rewritten prompt: Ends by producing the prompt the user should have written, with resolved unknowns folded in, and offers to proceed with it. - Use Case: Before modifying an unfamiliar payment module, run the pass to discover a deprecated API migration in progress, a known race condition guard, and the team's naming conventions, then start work with a corrected prompt. ## Quick Start Run a blind spot pass on my plan to add caching to the search service and tell me what I'm missing.
