Essential command-line tools and system utilities.
Debug “backend won’t start / first request 500 / ports stuck” quickly. Use when uvicorn reload behaves strangely, ports 8000/3000 are blocked, or you see first-request errors like “unexpected keyword argument” due to stale bytecode caches.
Hypothesis testing, root cause analysis, and debugging techniques. Use when debugging, testing hypotheses, validating solutions, proving correctness, or performing root cause analysis on failures.
Identify vulnerabilities in internet-facing systems using Shodan. Use for vulnerability assessment, CVE discovery, and security auditing. Triggers on requests for "vulnerability scan", "find vulns", "CVE check", or "security assessment".
ALWAYS USE FIRST when exploring, searching, or researching this codebase. Use symbol_tree MCP tool before grep/glob/read. Provides instant architecture overview, function relationships, and call graphs without reading full implementations.
Expanded smart-grep playbook for token-efficient rg --json searches with examples and budgeting.
Use when animation feels wrong and you need to diagnose which principle is failing or being misapplied
Start real-time log streaming from connected Android device using adb logcat. Shows only app's log messages. Use when monitoring app behavior, debugging, or viewing Android logs.
Initial reconnaissance on binaries including checksec, file analysis, strings, and symbols. First step for any new target.
Use when working with Ruby metaprogramming features including dynamic method definition, method_missing, class_eval, define_method, and reflection.
Show the name of the currently active profile
Tools and commands for debugging Rust OS kernel, UEFI bootloader, and user-space programs.
Expert on wgpu GPU rendering, WGSL shaders, and GPU pipeline configuration. Use when discussing rendering, shaders, GPU, textures, or graphics pipeline.
Use this skill when users need to conduct digital forensics investigations, perform timeline reconstruction, analyze memory dumps, examine artifacts, or build comprehensive forensic reports using LimaCharlie's forensic capabilities.
Xenium benchmarking 本地文档快照（全量 HTML）- 包含完整模块文档
Apply systematic debugging methodology using medical differential diagnosis principles. Trigger when AI modifies working code and anomalies occur, or when users report unexpected test results or execution failures. Use observation without preconception, fact isolation, differential diagnosis lists, deductive exclusion, experimental verification, precise fixes, and prevention mechanisms.
This skill should be used when the user asks about "Ruby performance", "optimization", "profiling", "benchmarking", "memory", "garbage collection", "GC", "benchmark-ips", "stackprof", "memory_profiler", "slow code", "speed up Ruby", or needs guidance on making Ruby code faster.
Use when facing any animation problem as a comprehensive diagnostic framework
ClickHouse incident response, periodic audits, and ad-hoc debugging via focused agents (run in waves). Uses ClickHouse system tables to diagnose slow queries/inserts, too many parts/merge backlog, wrong partitioning, log-table errors, replication/Keeper lag, and memory/disk pressure, producing an RCA-style report with reproducible artifacts.
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
Use when you need a detailed execution trace of a Python script using sys.monitoring, including logging every operation with include/exclude event controls.
3D Gaussian volumetric rendering specialist. Debugs anisotropic stretching, transparency artifacts, cube-like rendering, and particle visual quality. Uses gaussian-analyzer MCP tools for particle structure validation and shader optimization.
Checks code for accessibility issues including missing alt text, poor color contrast, missing ARIA labels, keyboard navigation issues, screen reader compatibility, and focus management. Returns structured accessibility issue reports with WCAG compliance information.
