Health-check the wiki and apply confidence decay. This skill should be used when the user says "lint", "检查wiki", "check the wiki", or wants to find orphan pages, broken links, contradictions, or stale concepts. Runs the 30-day confidence decay rule and reports issues for the user to fix.
Core operating rules for the student knowledge wiki. This skill should be used whenever working inside an Obsidian vault that contains a wiki/ folder with hot.md, or when the user mentions ingest, lint, review, exam-prep, or asks to build/maintain their course knowledge base. Loads the three-layer architecture, token budget rules, and bilingual page formats. Always loads first.
Digest a course source file into the wiki. This skill should be used when the user says "ingest", "消化", "process this PDF/slide", or drops a course file into raw/ and wants it turned into wiki pages. Reads the source, deduplicates via manifest, creates source + concept pages, and finds cross-course connections.
Add Mermaid diagrams to wiki pages to aid understanding. This skill should be used during ingest/review when a concept involves a process, architecture, sequence, hierarchy, or comparison that is easier to grasp visually, or when the user explicitly asks to "画图"/"配图"/"diagram"/"visualize" a concept.
Generate practice exam questions from weak concepts. This skill should be used when the user says "exam-prep", "备考", "make practice questions", "generate a quiz", or is preparing for an exam in a specific course. Scans concept pages, prioritizes low-confidence ones, and writes a practice question set.
Feynman-technique review mode for studying. This skill should be used when the user says "review", "复习", "quiz me", "test my understanding", or names a course/concept they want to study. Quizzes the user, adjusts confidence based on answers, and generates practice questions for weak concepts.
