Effect v4 (beta) development and v3 → v4 migration guidance. Use when building new Effect v4 code or upgrading from v3, including API renames, behavior changes, before/after examples, and v4-specific patterns for services, layers, generators, yieldable, error handling, and schema codecs.
Execute an approved implementation plan exactly and safely. Use when a plan already exists (for example in docs/plans/...) and work must be carried out phase-by-phase with verification checkpoints, status tracking, and final execution reporting.
Quickly search the user's library of real experiences, opinions and case materials (over 1800 entries) to add authenticity and credibility to content. Use this skill when the user mentions "real experience", "personal case", "well-founded", "practical experience", "material library" or "looking for examples".
Visual UI annotation tool for AI agents. Drop the React toolbar into any app — humans click elements and leave feedback, agents receive structured CSS selectors, bounding boxes, and React component trees to find exact code. Supports MCP watch-loop, platform-specific hooks (Claude Code / Codex / Gemini CLI / OpenCode), webhook delivery, and autonomous self-driving critique with agent-browser.
Send emails through SMTP with optional local attachments and optional IMAP APPEND sync to Sent mailbox. Use when tasks need reliable outbound email delivery, attachment sending, SMTP connectivity checks, or cross-client sent-mail visibility (for example appending to "Sent Items" after SMTP send).
Use when researching React APIs or concepts for documentation. Use when you need authoritative usage examples, caveats, warnings, or errors for a React feature.
Create or update an operational runbook for a recurring task or procedure. Use when documenting a task that on-call or ops needs to run repeatably, turning tribal knowledge into exact step-by-step commands, adding troubleshooting and rollback steps to an existing procedure, or writing escalation paths for when things go wrong.
Create AI avatar videos with precise control over avatars, voices, scripts, scenes, and backgrounds using HeyGen's v2 API. Use when: (1) Choosing a specific avatar and voice for a video, (2) Writing exact scripts for an avatar to speak, (3) Building multi-scene videos with different backgrounds per scene, (4) Creating transparent WebM videos for compositing, (5) Using talking photos as video presenters, (6) Integrating HeyGen avatars with Remotion, (7) Batch video generation with exact specs, (8) Brand-consistent production videos with precise control.
Structure a pattern library entry with problem context, solution pattern, usage examples, and related patterns.
Best practices and example-driven guidance for building SwiftUI views and components. Use when creating or refactoring SwiftUI UI, designing tab architecture with TabView, composing screens, or needing component-specific patterns and examples.
Provides guidance for property-based testing across multiple languages and smart contracts. Use when writing tests, reviewing code with serialization/validation/parsing patterns, designing features, or when property-based testing would provide stronger coverage than example-based tests.
Generate comprehensive, developer-friendly API documentation from code, including endpoints, parameters, examples, and best practices
