gemini
Execute Gemini CLI for AI-powered code analysis and generation. Use when you need to leverage Google's Gemini models for complex reasoning tasks.
docs-write
Write documentation following Metabase's conversational, clear, and user-focused style. Use when creating or editing documentation files (markdown, MDX, etc.).
excalidraw-architect
Create diagrams, flowcharts, and architecture visualizations using Excalidraw. Use when user requests "create diagram", "draw flowchart", "architecture diagram", or mentions Excalidraw, visualization, system design.
systematic-debugging
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes - four-phase framework (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures understanding before attempting solutions
canvas-design
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
market-analysis
Use when analyzing markets or interpreting charts - applies technical indicators (RSI, MACD, Moving Averages), identifies support/resistance, analyzes multi-timeframe trends, checks fundamentals and sentiment. Activates when user says "analyze BTC", "what's the trend", "check this chart", mentions ticker symbols, or uses /trading:analyze command.
qa-tester
"Browser automation QA testing skill. Systematically tests web applications for functionality, security, and usability issues. Reports findings by severity (CRITICAL/HIGH/MEDIUM/LOW) with immediate alerts for critical failures."
ultrathink
Invoke deep sequential thinking for complex problem-solving. Use when the user says 'use ultrathink', 'ultrathink', or when tackling problems that require careful step-by-step reasoning, planning, hypothesis generation, or multi-step analysis.
patent-search
Advanced prior art search using the PatentsView API. Use this skill when users need to search for patents, perform prior art searches, analyze patent landscapes, or find patents by inventor, title, date range, or technical fields. Helps with patent research, freedom to operate analysis, and competitive intelligence.
