Testing

Counts features marked as @failing in Gherkin files and writes the count to feature-status.json. Used by the autonomous coding harness to decide when to stop the coding loop when all features pass.

Development

Creates new evaluation metrics for the Fair-Forge AI library. Generates all required files including implementation, schema, tests, fixtures, optional dependency group, and example notebook following established patterns. Use when adding a new evaluation metric to Fair-Forge.

Productivity

Downloads YouTube video transcripts, translates them to Vietnamese, and provides AI-powered summarization. Saves outputs locally with metadata and structured files. Helps with learning English from YouTube, building a personal knowledge base, and extracting insights from video content.

Development

Provides performance optimization patterns covering Core Web Vitals, React render optimization with memoization and virtualization, lazy loading and code splitting, image optimization (AVIF/WebP, responsive images), backend profiling (py-spy, React DevTools), and LLM inference optimization (vLLM, quantization). Use when aiming to improve page speed, debug slow renders, optimize bundle size, reduce image payload, profile backend performance, or deploy LLMs efficiently.

Documentation

Synthesizes harvested session data and project analysis into structured Obsidian-compatible markdown notes with proper frontmatter, tags, and links. Creates daily session logs, project index files, and architecture notes. Helps maintain a connected knowledge base by automatically generating tags and bidirectional links between notes.

Content

A multi-agent video creation management tool with 11 agents and a 5-stage workflow to address video synthesis and quality control issues.

Development

Helps create and run custom Claude Code agents by defining agent configurations using --agents JSON and executing them via --agent flag. Useful when users need to build specialized agents for specific tasks or migrate agents from other formats like OpenCode.

Data & AI

Build an interactive technical analysis dashboard using Plotly Dash or Streamlit. Supports single-symbol, multi-symbol, and multi-timeframe layouts with real-time refresh. Helps visualize indicators and monitor financial markets in real time.

Testing

Extracts HTTP/HTTPS request/response data from Charles Proxy .chlsj files. Use it to analyze captured network traffic, debug API calls, or examine proxy logs.

Data & AI

Troubleshooting guide for common Runway errors in AI video generation and creative AI tasks.

Development

This skill helps you create and modify Lua plugins for Open Brush, a VR painting application. It provides access to the complete Open Brush Lua API documentation. Use it when you want to develop plugins, write Lua scripts, or ask about Open Brush scripting APIs.

Productivity

Analyzes a Claude Code session transcript to auto-generate structured summaries: work done, decisions made, next steps, and notes. Helps keep session records concise and actionable without manually reviewing the full conversation.
