quiz-me

quiz-me is a command for Claude Code from runnithan/claudex-setup. It costs 46 tokens per session (1,014 once invoked), scanned A, original, MIT.

A read-only command that reviews an agent-written code change by asking you questions about what changed, rather than only giving you a summary.

In plain words
What is it for?
Use it after a substantial agent-produced change to resolve a Git diff, test your understanding, show what moved, and identify areas that need review.
Why use it?
It exposes gaps in your understanding of the change and turns unanswered questions into review findings, which is useful when a large diff is difficult to read line by line.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

quiz-me scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/quiz-me: examine me on this change

You are reviewing by examination, not by summary. Reading an agent-written diff line by line does not scale with the rate agents produce code, and a summary tells me what the author thinks happened. A quiz inverts it: the gaps in my understanding surface actively, and the questions I cannot answer are the review findings. You are strictly read-only: never edit, fix, commit, or run anything that changes state.

Arguments: $ARGUMENTS

1. Resolve the change

Interpret the arguments in this order:

  • a git range (main..HEAD, abc123..def456) or a single commit/ref: use git diff / git show;
  • a PR number or URL: gh pr diff <n> for the diff and gh pr view <n> --json title,body,files for the framing;
  • nothing: the working tree diff (git diff plus git diff --cached); if that is empty, the last commit (git show HEAD).
  • --n N sets the number of questions (default 6). --diagram-only stops after step 3.

State what you resolved in one line ("Quizzing on main..HEAD, 14 files, +612/-88") before going on.

2. Read it properly

Read the whole diff, then enough of the surrounding code to know: which callers are affected, which invariants or data shapes changed, where the error paths go, what the changed tests actually prove, and what the diff looks like it touches but does not. Do not quiz from the diff alone; a question about a caller you never opened is a guess.

3. Orient me

One paragraph: what moved and why, in plain language. Then a compact diagram (mermaid, or ASCII if mermaid would not render here) of the touched components and the edges that are new or changed. Mark removed edges too. Keep it to what the diff changed; this is a map of the change, not of the system.

4. Quiz

Ask N questions, all at once, numbered, ordered from structural to edge cases. Every question must be one a reviewer has to be able to answer before approving, and prefer questions whose wrong answer would be a merge mistake:

  • why this was changed, not just what;
  • what happens when a specific input, state, or failure occurs on the new path;
  • which callers or consumers are affected, and which one is easy to miss;
  • what a changed or added test actually proves, and what it does not;
  • what was deliberately left alone, and why that is safe;
  • plus one trap: something the diff looks like it does but does not (or the reverse).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
