feat(thinking-tools): add quiz-me skill

[mickzijdel]

Summary

• Adds a quiz-me skill to thinking-tools (v1.2.1 → v1.3.0)
• Inspired by Geoffrey Litt's feed item (2026-06-28): have coding agents quiz developers on their modifications to build genuine comprehension
• Active recall beats passive reading: instead of the agent explaining, the developer is questioned on key decisions, patterns, and edge cases in the change

What the skill does

1. Surveys the current diff — identifies 3–5 key decisions, mechanisms, and non-obvious constraints introduced
2. Constructs 4–6 targeted questions covering five types: recall (basic concept), reasoning (why this approach), implication (what follows), trace (follow the execution), and edge case (boundary condition) — at least one trace and one implication required
3. Presents questions one at a time — no list upfront (prevents skimming ahead); waits for each answer
4. Scores and explains each answer — confirms what was right, fills gaps, explains the principle behind wrong answers so the mistake doesn't recur
5. Ends with a comprehension summary and any follow-up action (e.g. "worth adding a comment to X")

What changed

• plugins/thinking-tools/skills/quiz-me/SKILL.md — new skill
• plugins/thinking-tools/.claude-plugin/plugin.json — version bump, description updated, comprehension/learning keywords added
• plugins/thinking-tools/README.md — new row in skills table + usage example
• README.md — thinking-tools entry updated to include quiz-me

How it's distinct from existing skills

Skill	Focus
grill-me	Attacks the code for bugs, security holes, edge cases
but-for-real	Verifies the agent's claims about the change
code-simplifier	Style, clarity, and refactoring
self-rate	Grades the agent's own work quality
quiz-me	Builds the developer's comprehension of what the agent just did

Test plan

• uv run pytest -q — no test changes needed; quiz-me is a pure skill
• Verify skill table in plugins/thinking-tools/README.md renders correctly
• Invoke /quiz-me after a small implementation and confirm it goes straight to Q1 without preamble
