Essential command-line tools and system utilities.
Python >=3.11 performance optimization guidelines. This skill should be used when writing, reviewing, or refactoring Python code to ensure optimal performance patterns. Triggers on tasks involving asyncio, data structures, memory management, serialization, concurrency, or Python performance optimization.
解析云快充充电桩通信协议报文,支持CRC16校验、多种帧类型解析、错误诊断,返回标准JSON格式。用于处理云快充协议V1.6的报文数据。
Complete guide for Chrome DevTools CLI - browser automation, debugging, performance analysis, network inspection. Use when automating Chrome, taking screenshots, analyzing performance, monitoring network/console, device emulation, or user mentions chrome-devtools, browser automation, puppeteer, debugging, performance testing, screenshot, network monitoring, console monitoring, or 크롬 개발자도구, 브라우저 자동화, 디버깅, 성능 분석.
Use when comparing a frontend implementation against a reference design (Figma, mockup, screenshot). Performs pixel-level and structural analysis to identify discrepancies.
Processes and analyzes TiDB profiler zip packages (CPU or heap) for components like TiDB, TiKV, PD, or TiFlash. It unzips, aggregates the profiler data, and uses `go tool pprof` to report on the most time-consuming functions (CPU) or highest memory allocations (heap).
Performance optimization patterns for Mem0 memory operations including query optimization, caching strategies, embedding efficiency, database tuning, batch operations, and cost reduction for both Platform and OSS deployments. Use when optimizing memory performance, reducing costs, improving query speed, implementing caching, tuning database performance, analyzing bottlenecks, or when user mentions memory optimization, performance tuning, cost reduction, slow queries, caching, or Mem0 optimization.
Managing Claude Code Session Memory & Context. Understand session context limits, use just-in-time retrieval, cache insights, manage memory files. Use when optimizing context usage, handling large projects, or implementing efficient workflows.
Optimize caching strategies for performance. Use when analyzing cache effectiveness, implementing multi-layer caching, optimizing Redis/memory caches, or troubleshooting slow response times.
Quick RxSwift memory leak detection for iOS. Finds missing dispose bags, retain cycles, and strong self references. Use when debugging memory issues, checking Observable subscriptions, or investigating retain cycles in RxSwift code.
Detects optimization barriers during Truffle compilation. Identifies virtual calls, non-constant stores, unresolved type checks, and TruffleBoundary issues that prevent peak performance. Reports exact source locations with stack traces. Use as essential step for eliminating compilation warnings. ONLY works with traditional Truffle DSL nodes (NOT Bytecode DSL).
Confirm a requested feature change via AERA Debug mode (Debug view, console, logs). Use when validation must happen through Debug UI or when you need to add debug-only probes/commands to make a change observable.
Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack, adding instrumentation when needed, to identify source of invalid data or incorrect behavior
Setup VSCode for F5 Python debugging in UE5 editor. Use when users need to (1) configure VSCode for UE5 Python debugging, (2) setup debugpy remote debugging workflow, (3) enable breakpoint debugging in UE5 Python scripts, or (4) create VSCode launch/task configurations for UE5.
Debug Django web applications with systematic diagnostic approaches. This skill covers troubleshooting Django-specific errors including TemplateDoesNotExist, ImproperlyConfigured, IntegrityError, migration conflicts, CSRF failures, N+1 query problems, and circular imports. Includes Django Debug Toolbar setup, ORM query logging, pdb/ipdb usage, shell_plus debugging, and comprehensive logging configuration. Provides four-phase methodology for root cause analysis and regression prevention.
Performance optimization with profiling, memory analysis, and benchmarking
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.
Lightweight Chromium DevTools automation via the bundled browser-tools.ts CLI (Puppeteer connect). Use when you need to launch a Chromium-based browser with a remote-debugging port, navigate pages, run JS in the active tab, capture screenshots, inspect DevTools sessions, or extract readable content without a full browser automation server.
Retrieve Unity Console logs via uloop CLI. Use when you need to: (1) Check for errors or warnings after operations, (2) Debug runtime issues in Unity Editor, (3) Investigate unexpected behavior or exceptions.
This skill should be used when adding error handling to catch blocks, standardizing error handling across a codebase, or ensuring proper UX with user messages vs technical logs. Covers NotificationOptions, Hooks.onError, and preventing console noise.
Execute when you see "[MEMORY_KEEPER]" in hook output. Follow the numbered steps exactly to save session memory.
