Essential command-line tools and system utilities.
Cursor context management with /summarize command, @ mentions for file inclusion, and @codebase discovery. Use when operating in Cursor IDE or when context exceeds 60%. Activate for context optimization in Cursor sessions.
This skill should be used when debugging web applications, diagnosing page errors, inspecting console output, or capturing screenshots of pages. It provides Chrome DevTools Protocol (CDP) automation via the chromectl.py script for collaborative or automated browser debugging.
Analyze and map code structure, data flow, and dependencies in legacy codebases. Use for understanding call stacks, dependency trees, side effects, risk profiles, and generating Mermaid diagrams. Ideal for legacy codebases with zero tests.
Parse and filter cargo build logs to extract errors, warnings, and diagnostics with regex-based filtering. Use when debugging Rust projects, analyzing cargo build output, filtering errors by file path or message pattern, or helping users understand compilation failures. Triggers on cargo build errors, rustc diagnostics, Rust compilation issues, or requests to parse .log files from cargo.
Debuggt VBA-Fehler in MS Access und fügt professionelles Error-Handling hinzu
Debug Express.js and Node.js applications with systematic diagnostic techniques. This skill provides comprehensive guidance for troubleshooting middleware execution issues, routing problems, CORS errors, async error handling, memory leaks, and unhandled promise rejections. Covers DEBUG environment variable usage, Node Inspector with Chrome DevTools, VS Code debugging, Morgan request logging, and diagnostic middleware patterns. Includes four-phase debugging methodology and common error message reference.
Checks current context window usage and provides recommendations. Use when sessions feel slow, responses seem degraded, or before starting complex work.
Performance optimization with profiling, bottleneck detection, and tuning strategies.
This skill should be used when the user asks about "lazy.nvim", "plugin performance", "neovim startup time", "slow neovim", "optimize plugins", "lazy-loading", "startuptime profiling", or wants to improve Neovim performance through better plugin management.
Find and fix unsafe error handling in Leavn - try! force unwraps, empty catch blocks, silent try? failures
Hybrid search strategy for finding relevant code: fast targeted search, then deep analysis if needed.
Expert in system optimization, profiling, and scalability. Specializes in eBPF, Flamegraphs, and kernel-level tuning.
Analyse throughput, case duration, and activity sojourn times from the filtered log.
