Common errors and solutions for GPUI development. Use when debugging build errors, runtime panics, borrow checker issues, or unexpected behavior.
Simplified memory profiling and leak detection for SDL3 HammerEngine using valgrind memcheck, AddressSanitizer, and massif. Identifies memory leaks, allocation hotspots, buffer reuse violations, and provides system-by-system memory breakdown with optimization suggestions. Use after performance-critical changes or when investigating memory issues.
Systematic debugging mode with hypothesis-driven investigation. Use when user reports a bug, encounters an error, or needs help debugging a problem.
CRITICAL for ALL Elixir/Phoenix/Ash development work. Invoke when working with Elixir code, Ecto schemas, Ash resources, Phoenix applications, or databases in Elixir projects. Provides MCP tools for live code evaluation (via IEx), instant module navigation, direct SQL execution, schema introspection, and documentation access. Tidewave provides superior alternatives to bash/grep/read for Elixir tasks.
HTTP request and response analysis for debugging API calls, identifying failed requests, and understanding data flow. Use when investigating API issues, authentication problems, or data loading failures.

Network connectivity diagnostics including ping, DNS lookup, port scanning, and HTTP requests. Use when debugging network issues, checking connectivity, or testing endpoints.
Performance - Core Web Vitals, bundle size. Use when optimizing speed.
Find and fix issues from Sentry using MCP. Use when asked to fix Sentry errors, debug production issues, investigate exceptions, or resolve bugs reported in Sentry. Methodically analyzes stack traces, breadcrumbs, traces, and context to identify root causes.
Analyze and optimize system throughput including request handling, data processing, and resource utilization. Use when identifying capacity limits or evaluating scaling strategies. Trigger with phrases like "analyze throughput", "optimize capacity", or "identify bottlenecks".
Use when analyzing code structure, researching codebase, investigating architecture, exploring dependencies, creating reports, auditing code quality, or when asked to проанализировать, исследовать, изучить, составить отчёт, провести аудит - provides structured approach for exploration tasks without immediate code changes
Analyze network latency and optimize request patterns for faster communication. Use when diagnosing slow network performance or optimizing API calls. Trigger with phrases like "analyze network latency", "optimize API calls", or "reduce network delays".
Performance optimization specialist for improving application speed and efficiency. Use when investigating performance issues or optimizing code.
Monitor and analyze application error rates to improve reliability. Use when tracking errors in applications including HTTP errors, exceptions, and database issues. Trigger with phrases like "monitor error rates", "track application errors", or "analyze error patterns".
Systematically reproduce, diagnose, and analyze bugs to determine root cause, assess severity, and plan fix strategy
This skill should be used when the user asks to "write postmortem", "create postmortem document", "document code issue", "postmortem best practices", "postmortem format", or needs guidance on structuring and writing effective postmortem documentation for code fixes.
UniTask library expert specializing in allocation-free async/await patterns, coroutine migration, and Unity-optimized asynchronous programming. Masters UniTask performance optimizations, cancellation handling, and memory-efficient async operations. Use PROACTIVELY for UniTask implementation, async optimization, or coroutine replacement.
Analyze, consolidate, and document codebases through multi-perspective analysis. Identifies duplicate code, refactoring opportunities, architectural patterns, and generates comprehensive reports. Use when reviewing project structure, planning refactoring, creating documentation, or assessing technical debt.
Overview of protected quality thresholds and quick reference for all quality tools. Use when you need to understand quality metrics, run comprehensive quality checks, or learn which specialized skill to use. For specific issues, use dedicated skills (deptrac-fixer for Deptrac, complexity-management for PHPInsights, testing-workflow for coverage).
