1Code Review Expertcode-review-expert is a sanyuan-skills agent workflow that performs structured review of current git changes with a senior engineer lens. Findings are classified into severity levels—P0 critical blockers for security and correctness, P1 high issues for logic and SOLID violations, and lower tiers for smaller concerns—with explicit merge guidance per level. The skill defaults to review-only output unless the user requests fixes, covering architecture smells, dead-code removal candidates, and security risks. Developers invoke code-review-expert on active branches or pull requests when they want actionable, prioritized feedback instead of generic style nitpicks.7.7kinstalls2Sigmasigma is an agent skill implementing a personalized one-on-one tutor based on Bloom's 2-Sigma mastery learning with Socratic questioning, adaptive pacing, and rich visual outputs. Core rules forbid giving answers directly, require diagnosis before teaching, gate advancement on roughly 80 percent mastery, limit rounds to one or two questions, and match the user's language while keeping technical terms in English when helpful. Sessions persist under sigma/ with learner-profile.md, per-topic session.md, roadmap.html, Excalidraw concept maps, visuals, and summary.html artifacts. The workflow loads profile, diagnoses level, builds a concept roadmap, runs a tutor loop with misconception tracking and spaced repetition on resume, and supports /sigma topic arguments with --level, --lang, --resume, and --visual flags. Developers reach for sigma when learning frameworks, languages, or system design concepts through guided discovery rather than copy-paste explanations from the agent.2.8kinstalls3Skill ForgeIRON LAW Every line in a skill must justify its token cost If it doesn t make the model s output better more consistent or more reliable cut it A skill is an onboarding guide for Claude transforming it from a general purpose agent into a specialized one with procedural knowledge domain expertise and bundled tools skill name SKILL md Required workflow instructions 500 lines scripts Optional deterministic repeatable operations references Optional loaded into context on demand assets Optional used in output never loaded into context Default assumption Claude is already very smart Only add what Claude doesn t already know Challenge every paragraph Does this justify its token cost Copy this checklist and check off items as you complete them The skill forge agent skill provides documented workflows prerequisites triggers and safety guidance from its SKILL md source Agents load it when user requests match the description and follow step by step instructions without inventing capabilities It integrates with standard agent tooling for the tasks inputs outputs and failure2.2kinstalls4Book StudyBook Study is a reading coach agent that guides developers and learners through books with structured knowledge management. It covers four core workflows: pre-reading activation (connecting to user goals, priming prior knowledge), knowledge ingestion (extracting concepts, models, cases, quotes), Socratic mastery testing (explanation + example + application), and spaced-repetition review (1-day, 3-day, 7-day, 14-day, 30-day, 60-day intervals). The system maintains a local wiki (book-wiki/) organized by book slug, with chapters, concepts, cases, models, quotes, and questions directories. Cross-book concept aggregation tracks shared ideas across multiple books. Users invoke via /book-study <book-name> or sub-commands (ingest, query, review, compare, status). State restoration on each session ensures continuous progress tracking and adaptive next-step suggestions.1.7kinstalls5Wiki IngestThe wiki-ingest skill compile articles, documents, or notes into a structured wiki knowledge base. Use when user says 'ingest to wiki', 'compile to knowledge base', 'update wiki', 'wiki ingest', 'add this to wiki', or invokes /wiki-ingest. Supports single or batch ingest. Triggers: wiki, ingest, knowledge base, compile, digest, index, catalog. # Wiki Ingest - Knowledge Base Compiler Compile any text content (articles, documents, notes) into structured wiki pages with cross-references, building a searchable, interconnected knowledge network. IRON LAW: One wiki page = one knowledge entity. Never cram multiple concepts into one page. ## Wiki Directory Structure Wiki defaults to `wiki/` under the current project root. User may specify a different path. ``` wiki/ ├── index.md # Full table of contents ├── log.md # Append-only operation log ├── concepts/ # Core concept pages ├── products/ # Product/tool entity pages ├── patterns/ # Engineering patterns & design decisions └── comparisons/ # Cross-topic comparison pages ``` ## Workflow ### 1. Confirm Input Accept user-specified content source: - Pasted text directly - File path(s) (md, txt, pdf, etc.) - Directory path (batch processing).1.3kinstalls6Skill ReviewSkill Review is a quality audit skill from sanyuan0704/sanyuan-skills for Claude Code skill authors. It analyzes skill structure, description quality, workflow design, token efficiency, and anti-patterns against documented best practices. The iron law requires every critique to state exactly what to change and why it matters for model behavior—never vague "could be improved" feedback. Trigger phrases include review skill, audit skill, skill quality, check my skill, evaluate skill, skill lint, validate skill, and improve this skill. Developers reach for Skill Review after drafting a SKILL.md and before sharing it with a team or publishing to a skill catalog, when they need a structured pass that catches weak descriptions, bloated prompts, and workflow gaps.1kinstalls
