Troubleshooting guide for IPC communication issues between Main and Renderer processes
Practical guidance for Claude Code status lines - what to display for real workflow benefits, not just configuration syntax. Use when setting up status lines or wondering what information would actually help.
Maps a code change or bug symptom to the smallest high-signal test subset. Use when deciding what tests to run (DET_/FLOW_/REG_), when a regression guard mentions a test ID, or when you need a minimal repro that matches tests/TEST_MATRIX_detection_and_flow.md.
Use when encountering n8n workflow issues, Code node errors, HTTP requests failing, data flow problems, environment variables not working, JSON parsing errors, or need n8n development patterns and debugging strategies
Evidence-based debugging protocol using the scientific method. REQUIRES ONE-TIME INITIALIZATION before use. Use when standard debugging has failed and maximum rigor is needed.
Preview and screenshot local dev servers and storybooks. Use when asked to view UI components, take screenshots of storybooks, or inspect the web/server apps.
Traces deoptimization events where execution falls back from compiled code to interpreter. Use to detect deoptimization loops, unstable assumptions, and type instability. Zero transfers in steady-state is the goal. Many transfers indicate severe performance problems. Critical for diagnosing compilation instability.
Analyze mobile device data for forensic investigation. Use when investigating incidents involving iOS or Android devices, mobile malware, data theft, or communications analysis. Supports logical and file system extractions.
Perform accessibility audit on web pages. Use when users ask to check accessibility, audit WCAG compliance, verify ARIA usage, check color contrast, audit keyboard navigation, or analyze screen reader compatibility. Detects ARIA issues, focus problems, contrast issues, and semantic HTML violations.
This skill should be used when the user asks to find and fix SwiftUI performance issues, optimize SwiftUI views, fix re-render problems, or analyze why their iOS/macOS app UI is slow. It handles the full workflow from code review to trace analysis.
Monitor and optimize search performance with Google Search Console.
Best practices for JavaScript/TypeScript development including modern ES6+ patterns, error handling, and performance optimization.
Use when optimizing code for performance, reducing bundle size, improving load times, or fixing performance bottlenecks. Emphasizes measurement-driven optimization.
Expert code review for TypeScript/Node.js applications focusing on quality and best practices
Systematic debugging by tracing data backwards from symptom to root cause. Uses HelixDB for relationships, Repo Prompt for inspection. Trigger when investigating bugs or unexpected behavior.
Query and analyze Cloudflare Workers logs. Use for debugging workers, checking error rates, viewing request logs. Activates with phrases like "check worker logs", "what errors are in the worker", "cloudflare logs", "worker observability".
Core exploitation techniques for binary vulnerabilities
Swift Concurrency review and remediation for Swift 6.2+. Use when asked to review Swift Concurrency usage, improve concurrency compliance, or fix Swift concurrency compiler errors in a feature or file.
