What problem does it solve? Claimed mastery often hides foundational gaps that standard quizzes and self-assessments miss. This Skill challenges a learner's stated expertise with deceptively simple questions and produces an evidence-backed map of real weaknesses. ## Core Features & Use Cases - Socratic Diagnostic: Asks five open questions one at a time targeting causal reasoning, boundary conditions, counterexamples, prediction, and transfer. - Evidence-Based Assessment: Classifies each answer as sound, incorrect, right for the wrong reason, or incomplete, quoting the consequential claim and citing source evidence when a codebase is involved. - Ranked Gap Map: Delivers a final summary of strengths and gaps ranked by practical consequence, each with a targeted exercise and success criteria. - Use Case: A developer claims senior-level understanding of database indexing. The Skill inspects their actual codebase, asks five probing questions about query plans and B-tree behavior, and reports which foundational concepts are genuinely solid versus shaky. ## Quick Start Ask the AI to run the hidden gap detector on your claimed expertise in a specific topic or codebase and answer each question with your reasoning.
