Documentation

Storybook stories, CSF3 format, autodocs. Use for component documentation.

Create documentation optimized for ADHD and neurodivergent readers with short scannable content, clear hierarchy, progressive disclosure, actionable steps, and reduced cognitive load. Use when creating or improving any technical documentation (README files, API docs, tutorials, guides, onboarding materials) or when users request accessible, easy-to-scan, or beginner-friendly documentation.

Expert knowledge for testing Composable Rust applications. Use when writing unit tests for reducers, setting up integration tests with real dependencies, using test utilities (TestStore, FixedClock, mocks), working with testcontainers for PostgreSQL/Redpanda, property-based testing, or questions about testing patterns and best practices.

PRIMARY tool for fetching library/framework documentation. PROACTIVELY use instead of WebFetch/WebSearch when user requests docs, API references, setup guides, or code examples for any programming library or framework. Use this skill immediately when detecting queries like "show me X docs", "how do I use Y", "get Z documentation", etc. Token-efficient alternative to MCP servers.

Guide development following Kent Beck's Test-Driven Development (TDD) using Red → Green → Refactor cycle. Use when writing tests first, implementing features with TDD, need to write failing tests, make tests pass, refactoring after tests pass, following red-green-refactor, fixing defects with tests, or practicing test-driven development methodology.

Transform organizational knowledge into professional, compliance-ready workflow documentation including SOPs, process maps, runbooks, and operational playbooks with built-in quality assurance and change management frameworks.

Convert Obsidian vaults to EPUB ebooks. Use when the user wants to create an ebook from Obsidian notes, export a vault as EPUB, or convert markdown notes to an ebook format.

Create, validate, and enhance blog posts. Use when creating new blog posts, validating frontmatter, checking post structure, suggesting categories, extracting images for social sharing, or managing blog content. Handles markdown posts with YAML frontmatter.

Convert Markdown documents to professional PDF files with syntax highlighting, custom templates, and BibTeX citations. Use when creating printable documents, reports, or academic papers from Markdown.

Flowcharts are composed of **nodes** (geometric shapes) and **edges** (arrows or lines). The Mermaid code defines how nodes and edges are made and accommodates different arrow types, multi-directional arrows, and any linking to and from subgraphs.

Create interactive data visualizations using D3.js. Use this when creating charts, graphs, network diagrams, geographic visualizations, or custom SVG-based data visualization.

specialized agent for writing high-quality, educational technical content for Docusaurus books. Focuses on clarity, engagement, and technical accuracy using modern documentation standards.

General software development practices including code review, testing strategies, and CI/CD integration. Use when implementing features, writing tests, setting up deployment pipelines, or conducting peer reviews.

TDD for process documentation - test with subagents before writing, iterate until bulletproof

Enforce strict TypeScript type safety rules including no 'any' types, explicit return types, proper interfaces, and type guards. Use when writing TypeScript code, reviewing code, refactoring, or when user mentions TypeScript, types, interfaces, or type safety.

Use when upgrading .c3/ documentation to current skill version - reads VERSION, applies transforms from migrations/ directory in batches

Guide for writing effective prompt specifications (specs) for the GPT-5.2 Codex agent. Use when the user asks to "write a prompt spec", "create a system prompt for GPT-5.2", "design a spec for an agent", or "how to prompt GPT-5.2".

Writing TypeScript predicate functions (type guards, boolean checks, validation functions). Use when creating functions that return boolean or perform type narrowing. Follows Sitebender's curried, pure function patterns with named function declarations.

Standards for documenting codebases. Use when writing documentation, deciding where docs should go, reviewing doc quality, or updating docs after code changes. Covers folder structure, content guidelines, and maintenance workflows.

This skill should be used when creating, editing, or debugging Mermaid diagrams. It provides comprehensive syntax references for all 20+ Mermaid diagram types including flowcharts, sequence diagrams, class diagrams, ER diagrams, Gantt charts, and more. Use this skill when users ask for diagrams, visualizations, flowcharts, or any Mermaid-related assistance.
