exam-audit

Purpose

Inspect a prep workspace built by exam-ingest and report health issues. This is a read-only inspector. Do NOT fix anything by default; only fix after the user explicitly grants permission. Emit a concrete issue report; never silently modify or delete files.

Activation

Activate when the user suspects the workspace is broken (missing chapters, ungradable quiz items, inconsistent progress), or when the user wants a pre-review health check before studying. Do not activate to build, teach, or grade.

Inputs

• references/wiki/ — chapter knowledge files (chN_*.md).
• references/quiz_bank.json — quiz items.
• study_plan.md — phase plan with chapter anchors.
• study_state.json — the structured progress state (the SINGLE SOURCE OF TRUTH when present: phase_checklist, mistake_archive, confusion_log).
• study_progress.md — a GENERATED VIEW of the state (rendered phase checkpoints and recorded wrong-question IDs); stale/hand-edited when it drifts from study_state.json.

Workflow

Inspect read-only. Open and parse files; never write, rename, or delete. Check each item below and record every failure as a concrete issue (file path + what is wrong).

1. Structure. For each phase listed in study_plan.md, confirm a matching references/wiki/chN_*.md file exists. Flag orphan chapters (wiki files no phase references) and broken links (phases pointing to absent chapters).
2. Quiz bank. For each item in references/quiz_bank.json: confirm type is one of the six allowed types (choice / subjective / diagram / fill_blank / true_false / code); confirm choice items carry options; confirm subjective items carry keywords; confirm any item missing answer carries the ⚠️ marker or source: ai_generated.
3. Provenance honesty. Flag any AI-generated answer presented as the teacher's standard answer (missing the ⚠️ marker). Flag any AI-supplement wiki passage that should carry 🟡 but does not.
4. Plan/progress consistency. When study_state.json exists, treat it as the source of truth: confirm study_progress.md is a faithful render of it (flag drift / stale hand-edits where the md disagrees with the state), and check the state's phase_checklist phases map to study_plan.md. When no study_state.json exists, audit study_progress.md directly. Either way, confirm each rendered phase-checkpoint line maps to a phase in study_plan.md and every wrong-question ID exists in references/quiz_bank.json. Note: the template anchor <!-- PHASE_CHECKLIST --> is replaced by scripts/ingest.py at generation time and is absent from a correct finished workspace — do NOT report its absence as a problem.
5. Path safety. Flag suspicious writes outside references/wiki/ and any residual ../ or absolute paths.

Output Contract

Emit a single issue list. Each entry contains: 【级别(阻断/警告/提示)】 (severity: blocker / warning / notice) + 【位置文件】 (file path) + 【现象】 (concrete symptom) + 【建议修法】 (suggested fix). End with an overall verdict: 可用 (usable) or 需修 (needs repair).

Do NOT auto-fix. After reporting, fix item-by-item only if the user grants permission, or hand the workspace back to exam-ingest for rebuild.

Student-facing output defaults to English (Simplified Chinese if the student opened in Chinese); a persisted study_state.json language (中文/English/双语) switches it per exam-cram's dispatch rule with single-language purity.

Language packs

This skill produces no student-facing template; its report is agent-composed in the student's language. There are no locales/zh/skills/exam-audit.md or locales/en/skills/exam-audit.md pack files — compose the issue report directly in the language given by study_state.json.language:

• zh → Simplified Chinese, using the zh canonical wording in ../../docs/language-policy.md
• en → English, using the EN canonical vocabulary in ../../docs/language-policy.md
• bilingual → compose zh-first with a > EN: mirror line per block (rules in ../../docs/language-policy.md) Unset language → this is the first conversation: the merged first-ask (mode × time budget × language) decides it; default en unless the student opened in Chinese.

Boundaries

• Zero modifications and zero deletions by default — this is an inspection, not construction.
• Do not infer the teacher's intent; report only objective inconsistencies and leave the judgment to the student.
