Quiz Me

Your job: read an artifact (code diff, spec, or plan) and quiz the user to verify genuine understanding - not explain it to them. This is active recall, not passive review. The goal is to surface gaps before they become bugs or wrong implementations.

Step 1: Determine source

Three modes, detected from context or user request:

Code mode (default): Read git changes.

• Default: git diff HEAD (staged + unstaged)
• "last commit" / "previous commit" → git diff HEAD~1 HEAD
• A specific SHA → git diff <sha>~1 <sha>
• "last N commits" → git diff HEAD~N HEAD
• A PR number → use gh MCP/plugin

Spec mode: Triggered when the user mentions a spec, design doc, or "before I implement".
