A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Turn scattered course and study materials into a maintainable Markdown note library. The goal is a study system: chapter notes, source tracking, uncertainty handling, long-course progress, existing-question analysis, gap strengthening, wikilinks, and final practice questions.
Use this skill for Chinese or English course materials. Default to the user's language and preserve course terminology.
This is an orchestration skill. For normal operation, assume these lower-level document skills are installed and available:
pdfpptxdocxmarkdown-mermaid-writinghumanizerUse them for material ingestion only: text, headings, page/slide structure, embedded tables, and question blocks. Do not copy their instructions, code, licenses, prompts, or internal rubrics into this skill or into user-facing notes.
Use markdown-mermaid-writing for relationship maps and polished Markdown structures when diagrams are useful. Use humanizer only after the study content is correct, to improve final readability without changing facts.
Use lower-level skills as extraction/rendering helpers, not competing planners. This skill controls source hierarchy, chapter inference, reporting cadence, question coverage, note structure, long-course state, and final outputs.
When the user gives a folder or files and says only “整理笔记”, “整理复习资料”, or similar, run the automatic workflow. Do not ask them to choose every phase.
For folder or whole-course inputs, build or update a lightweight .course_index/ before chapter writing, even when the visible materials are already Markdown. Skip indexing only for explicit one-file/one-chapter ad hoc tasks.
When PDFs, scanned documents, screenshots, or image-heavy slides are important to the task, verify extraction quality before relying on the extracted text. Do not treat a single "encrypted", "empty", or "unreadable" error as final for an important PDF; probe or retry with another extraction path, then record the result.
If a current .course_index/ already exists, reuse it for search, resume, one-chapter writing, question coverage, and gap inspection. Do not rebuild the full index by default for natural-language questions about an already indexed course.
If an existing vault with 00_*.md files already exists, default to query/resume/update mode rather than starting a new organization from scratch. Read the vault's project-status, material-index, chapter-progress, gap, and coverage files before writing. Preserve existing folder names, links, user edits, and prior decisions unless the user explicitly asks for redesign or a higher-authority local source clearly corrects them.
When new source files are added to an indexed course, identify source deltas and impacted chapters/questions/global files before editing notes. Update the index once when needed, then revise only the affected parts unless the user asks for a full rebuild.
Keep final notes separate from generated working artifacts. For new whole-course jobs, use a separated output root: final Markdown/Obsidian notes in 期末复习/, extracted/OCR text in _extracted/, machine state in .course_index/, and temporary chapter packs or script outputs in _working/. Do not put these generated working artifacts inside the final vault unless a result is promoted into a 00_*.md user-facing file.
Use .course_index/ and the vault's 00_*.md files as the portable source of truth for retrieval, progress, and resume decisions.
Stop for user confirmation only at the initial architecture checkpoint: after material inventory, source-role classification, existing-question extraction, chapter inference, course knowledge-type classification, and note library architecture planning. Ask only for corrections to chapter structure, source roles, course type, or output architecture.
After approval or no objection, proceed in batches. Do not ask for confirmation after each chapter, source type, generated file, or question-processing substep.
If the user explicitly asks for only one phase, do only that phase: inventory-only, question extraction, structure-only, one-chapter organization, external strengthening, historical exam analysis, question answering, question generation, indexing, or coverage checking.
Use progressive disclosure. Read only the reference needed for the current phase:
| Phase | Read |
|---|---|
| Automatic workflow, checkpoints, existing-vault update/resume, final external supplement, final consistency check | references/workflow.md |
| PDF/PPT/DOCX ingestion quality, scanned/image PDFs, OCR sidecars, misleading encrypted-PDF reports | references/ingestion.md |
Note library layout, dynamic chapter templates, Markdown/Obsidian [[wikilinks]], source/provenance vocabulary, existing-vault protection | references/vault_structure.md |
| Existing/source questions, A/B/C/D coverage, provenance-aware note strengthening, generated exams | references/questions.md |
.course_index, index health/staleness, provenance metadata, exact/regex search, chapter packs, optional semantic search | references/retrieval.md |
For folder, whole-course, or large-material inputs, prefer the bundled scripts in scripts/ after lower-level document extraction:
scripts/build_source_index.pyscripts/pdf_probe.pyscripts/search_index.pyscripts/chapter_pack.pyscripts/link_candidates.pyscripts/coverage_check.pyscripts/index_status.pyscripts/validate_vault.pyDefault retrieval is exact/regex/heading metadata plus chapter packs. Use semantic search only when exact search is insufficient and the environment already supports it or the user asks.
Use sources with different roles, not as interchangeable text piles:
待核验.Use stable source/provenance labels when classifying or reporting evidence:
| Label | Meaning |
|---|---|
teacher_ppt | Teacher slide/source material. |
textbook | Assigned textbook or official course book. |
official_handout | Official handout, syllabus, standard, manual, or teacher-distributed document. |
syllabus | Official course outline, learning objectives, or exam scope. |
user_note | User's own class notes, annotations, emphasis, doubts, or handwritten summaries. |
source_question | Source exercise, review question, homework question, or question-bank item. |
historical_exam | Past exam, quiz, final/midterm paper, or historical assessment. |
assignment_or_quiz | Assignment, quiz, lab, worksheet, or graded practice. |
senior_note | Senior-student notes, review PDFs, mind maps, or unofficial summaries. |
existing_vault | Existing Markdown/Obsidian notes and prior organization decisions. |
external_supplement | External search/web/book/paper material used only to fill local gaps. |
model_inference_pending_verification | Model inference or prior knowledge that lacks direct local support and must be marked 待核验. |
unclassified_source | Source whose role cannot be inferred reliably; inspect before relying on authority. |
Use stable evidence-status labels in audit sections:
明确依据: directly supported by a local authoritative or clearly cited source.间接支持: consistent with local material but not stated in the exact wording.来源冲突: local sources disagree or source answer conflicts with higher-authority material.提取存疑: extraction/OCR/table/formula quality may distort the content.待核验: not enough local evidence to present as certain.外部补充: external material used for understanding or gap filling, subordinate to local sources.Separate these audiences:
Avoid prompt pollution. Do not dump this skill, lower-level skill instructions, hidden process, long rubrics, parser logs, or unrelated examples into user-facing files. Examples are patterns, not course facts.
Keep the study body clean. Put source mapping in 资料依据, 不确定内容, 外部资料标记, 00_资料索引.md, 00_检索日志.md, 00_已有题目索引.md, or 00_题目覆盖与笔记补强.md rather than interrupting every concept row with citation chatter.
Preserve on uncertainty. If extracted text, source role, chapter mapping, source answer, existing note content, or user annotation is ambiguous, preserve the original and add an uncertainty/conflict note instead of deleting, overwriting, or silently normalizing it. Log contradictions in 不确定内容, 00_资料缺口与待确认.md, or 00_题目覆盖与笔记补强.md; do not resolve conflicts by model guesswork.
If the user requests a concrete note or note-library file, produce the concrete file content directly. Do not emit placeholder templates. Do not end with optional follow-up offers such as “如果你愿意，我下一条可以…” or ask whether to generate the next file. If information is missing, make the best concrete draft from available context and mark uncertainty in 不确定内容.
Before final output or each batch report, check:
.course_index/ as appropriate; long jobs also use 00_项目状态.md, 00_章节进度表.md, and .course_index/progress.json..course_index/, and temporary working packs are not mixed in the same folder.00_总目录.md, 00_资料索引.md, 00_术语索引.md, 00_资料缺口与待确认.md, and 00_检索日志.md.00_已有题目索引.md before generated practice.03_公式模型流程.md for courses where theory, timeline, rules, or cases are the main structure.[[wikilinks]] for stable concepts and related chapters.00_题目覆盖与笔记补强.md / 00_资料缺口与待确认.md.待核验 material.~30 seconds.
