| 1 | # exam-cheatsheet — pre-exam cheatsheet compiler |
| 2 | |
| 3 | ## Purpose |
| 4 | Compile, rather than free-generate, mastered content into workspace-root `cheatsheet.md`. Every top-level bullet must link into `notebook/`, `mistakes/`, or `references/wiki/`. Do not teach new material or invent questions. Render the requested-page-count PDF only for standing `visual` mode or an explicit PDF/print request. Never write the retired `walkthrough.md`; leave an existing copy untouched. |
| 5 | |
| 6 | ## Activation |
| 7 | Trigger on an explicit request for 「考前小抄 / 速记 / 总复习」, or when review is wrapping up after all phases and persisted `artifact_mode=visual`. Automatic final review under `chat` stays a conversational `exam-review` summary. |
| 8 | |
| 9 | ## Inputs |
| 10 | - Weak-spot source: `study_state.json` (`mistake_archive`, `confusion_log`, and `phase_checklist`) when it exists; otherwise the possibly stale generated `study_progress.md`. Read these first, then `mistakes/index.md` and `notebook/index.md` when present; their full entries provide preferred ready-made anchors. |
| 11 | - Rank `knowledge_window` status `out_window` above `in_window` and `verified` (codes are defined by `scripts/i18n.py`). |
| 12 | - Read core conclusions and formulas from every mastered chapter in `references/wiki/`, derived from `study_state.json`'s `current_phase`/`phase_checklist` when it exists, otherwise `study_progress.md`, checked against `study_plan.md`. Lazy-load one chapter at a time. |
| 13 | - Use `references/quiz_bank.json` for teacher-flagged items and answer frameworks. Resolve `scripts/select_hard_questions.py` from `${CLAUDE_SKILL_DIR}`, never the student workspace; it returns a flat ranked list which the agent groups by knowledge point. |
| 14 | |
| 15 | ## Workflow |
| 16 | 1. **Gate artifacts.** Read `study_state.json.artifact_mode`; missing, legacy, or unknown means `chat`. Never infer a subscription tier or add a fourth required first-contact question. Automatic `chat` review creates no sheet; an explicit sheet request may create Markdown. Only standing `visual` or an explicit one-shot PDF/print request authorizes rendering. A one-shot request does not modify the persisted value. Never install dependencies or skills silently. |
| 17 | 2. **Build the skeleton.** Weak spots come first. Per chapter retain only high-frequency or high-scoring formulas, conclusions, and one-sentence definitions. |
| 18 | 3. **Select one hard example per key point.** For each mastered chapter run `python "${CLAUDE_SKILL_DIR}/scripts/select_hard_questions.py" --workspace <ws> --chapter <N> --mode 查缺补漏 -n <M> --json`. Both `--chapter` and `--mode` are required: they avoid a missing-range failure in `某章起步补弱` and override easy-first `零基础从头讲`. Set `<M>` at least to the bank length so the default top ten cannot starve later points. Group the flat result, prioritize points linked to mistakes/confusions, and choose the hardest candidate per point. With no linked bank item, emit 「无题库例题」 and only the 「必背结论/公式」 and 「要点解释」 sections; never invent a replacement. |
| 19 | 4. **Fail closed on prompt assets.** For `requires_assets=true` or `maybe_requires_assets=true`, embed every `question_context`, `figure`, `diagram`, and `table` as workspace-relative `references/assets/` links, labeled `题面图` for `zh`/`bilingual` or `Question-side asset` for `en`. Preserve but never embed `student_attempt`; one declaration taints the same physical path across the complete quiz, teaching, and content-unit layers, including a duplicate official-looking declaration. Missing or unusable assets require a self-contained alternative. A `stub` or `page_reference` item likewise needs its original-page render or replacement by a `full` item. Never include an example whose prompt figure/page is invisible. `cheatsheet_render.py` performs the shared three-layer policy and canonical-path gate; do not bypass it with a custom Markdown/image renderer. |
| 20 | 5. **Write the four sections.** The worked solution states the formula, substituted values, and result; only intermediate arithmetic may be omitted. The takeaway starts with the recognition cue and then the answer framework. Material-backed lines may remain unlabeled; AI supplements require 🟡 AI补充,可能与你老师讲的不完全一致, AI answers require ⚠️ AI生成答案,非老师/教材提供, and missing/unknown bank answer provenance requires 「来源未知」. Do not let uncertain content inherit the material default; see [`docs/language-policy.md`](../../docs/language-policy.md). |
| 21 | 6. **Attach traceability.** End every top-level `- ` bullet with `[→](notebook/chNN.md#<anchor>)`, `[→](mistakes/chNN.md#<anchor>)`, or `[→](references/wiki/<file>.md)`, preferring notebook/mistake evidence. Run `python "${CLAUDE_SKILL_DIR}/scripts/validate_workspace.py" <ws>` and fix every untraced or dead link before delivery. |
| 22 | 7. **Write only when authorized.** Create workspace-root `c |
