NetGraph contributor development workflow. Use when: setting up dev environment, running tests or lint, fixing CI failures, running performance benchmarks, troubleshooting venv issues, or asking about make targets. For running scenarios and interpreting results, use netgraph-dsl instead.
Four-phase structured debugging methodology. Use when (1) tests fail unexpectedly, (2) functions produce wrong values, (3) systems show anomalous results, (4) unexpected errors appear, (5) performance regresses, (6) multiple quick fixes have already failed. Enforces root cause investigation before any fix attempt.
外部公開を想定したphpフレームワークのコードレビューをする際に、破壊的変更（breaking change）の有無を確認し、破壊的変更がある場合は適切に処理されているかをチェックするスキルです。
Optimizes Python library performance through profiling (cProfile, PyInstrument), memory analysis (memray, tracemalloc), benchmarking (pytest-benchmark), and optimization strategies. Use when analyzing performance bottlenecks, finding memory leaks, or setting up performance regression testing.
Use when you need to understand the codebase structure, find definitions, or trace references without reading entire files.
WHEN: Performance analysis, bundle size optimization, rendering, Core Web Vitals, code splitting WHAT: Bundle analysis + large dependency detection + re-render issues + useMemo/useCallback suggestions + LCP/FID/CLS improvements WHEN NOT: Code quality → code-reviewer, Security → security-scanner
Experimental allocation profiler tracking memory allocations at guest-language level. Shows allocation sites, object types, and memory pressure patterns. Use to identify allocation-heavy locations, find unnecessary object creation, and understand memory behavior. High allocations in hot loops = optimization opportunity if escape analysis isn't eliminating them.
Analyze network traffic captures and artifacts for forensic investigation. Use when investigating data exfiltration, command and control communications, lateral movement, or network-based attacks. Supports PCAP, PCAPNG, and NetFlow analysis.
Navigates WPF Visual Tree and Logical Tree with VisualTreeHelper and LogicalTreeHelper patterns. Use when traversing elements, accessing template internals, or understanding event routing.
Master binary analysis patterns including disassembly, decompilation, control flow analysis, and code pattern recognition. Use when analyzing executables, understanding compiled code, or performing static analysis on binaries.
Static triage for macOS .app bundles and Mach-O binaries; bundle map, signature/entitlements, imports/symbol hints.
Detect N+1 query patterns in the codebase. Finds loops that contain database or API calls that should be batched. Works across all languages. Use when user asks to find performance issues or N+1 patterns.
Comprehensive guide for implementing Fullstory's Logging API (log method) for web applications. Teaches proper log level usage, message formatting, and capturing application logs in session replay. Includes detailed good/bad examples for error tracking, debugging, and operational monitoring to help developers add contextual log messages to Fullstory sessions.
MCP testing guidance and patterns. Loaded by /ops/test/mcp command or subagents for comprehensive Navigator MCP server testing.
