Token-efficient codebase exploration using MCP servers (Serena, Context7, JetBrains, Claude-mem). Reduces token usage by 80-90% through structured queries. Use ALWAYS before reading files to minimize context wi...
Hypothesis-driven debugging with systematic investigation. Identifies root causes, creates minimal reproductions, and implements fixes. Use when investigating errors, bugs, crashes, or unexpected behavior.
Performance optimization and bottleneck detection. Identifies N+1 queries, memory leaks, async issues, and caching opportunities. Use when investigating slow operations, optimizing response times, or detecting...
Systematic code review with security, performance, and architecture analysis. Provides actionable fix suggestions and GitHub PR integration. Use when reviewing PRs, validating code changes, or checking code qua...
Hypothesis-driven debugging with systematic investigation. Identifies root causes, creates minimal reproductions, and implements fixes. Use when investigating errors, bugs, crashes, or unexpected behavior.
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 o...
Provides Go programming expertise, including language syntax, idiomatic patterns, concurrency, and standard library usage. Use when generating, analyzing, refactoring, or reviewing Go code.
Drupal cache debugging techniques and troubleshooting workflows. Use when asked about X-Drupal-Cache headers interpretation, finding max-age 0 sources, WebProfiler usage, cache hit/miss analysis, stale content...
Drupal cache max-age configuration and behavior. Use when asked about time-based cache expiration, Cache::PERMANENT, max-age 0 issues, why Page Cache ignores max-age, or when content appears stale despite time...
