Debugging Strategies

wshobson/agents
11.2k installs38.9k stars
Summary

When you're staring at a stack trace at 2 AM wondering why your code works locally but crashes in production, this skill walks you through systematic debugging instead of random console.log() hunting. It covers the scientific method for bug hunting, binary search techniques for isolating problems, and proper use of debuggers like Chrome DevTools, pdb, and Delve. The differential debugging approach is especially solid for those "works on my machine" situations where you methodically compare working vs broken environments. Less guesswork, more structured problem solving.

swiftui-performance-audit

dimillian/skills

Audit and improve SwiftUI runtime performance from code review and architecture. Use for requests to diagnose slow rendering, janky scrolling, high CPU/memory usage, excessive view updates, or layout thrash in SwiftUI apps, and to provide guidance for user-run Instruments profiling when code review alone is insufficient.

debug

anthropics/knowledge-work-plugins

Structured debugging session — reproduce, isolate, diagnose, and fix. Trigger with an error message or stack trace, "this works in staging but not prod", "something broke after the deploy", or when behavior diverges from expected and the cause isn't obvious.

debugging-wizard

jeffallan/claude-skills

Parses error messages, traces execution flow through stack traces, correlates log entries to identify failure points, and applies systematic hypothesis-driven methodology to isolate and resolve bugs. Use when investigating errors, analyzing stack traces, finding root causes of unexpected behavior, troubleshooting crashes, or performing log analysis, error investigation, or root cause analysis.

debug-mantra

thananon/9arm-skills

Four-mantra debugging discipline — reproduce, trace the fail path, falsify the hypothesis, cross-reference every breadcrumb. Recite the mantra block verbatim at the start of any debugging session, then apply the four steps in order before proposing any fix. Trigger on /debug-mantra and proactively whenever debugging starts — user reports a bug, says something is broken/throwing/failing, asks to debug/diagnose/investigate an issue, or pastes a stack trace or error log.

debugger

shubhamsaboo/awesome-llm-apps

Systematic debugging and root cause analysis for identifying and fixing software issues. Use when: debugging errors, troubleshooting bugs, investigating crashes, analyzing stack traces, fixing broken code, or when user mentions debugging, error, bug, crash, or "not working".

dpearson2699/swift-ios-skills

Debug iOS apps and profile performance using LLDB, the interactive Memory Graph Debugger, and Instruments. Use for crashes, retain-cycle inspection, hangs, build failures, and generic CPU, memory, energy, or network profiling. Use ios-memgraph-analysis for .memgraph capture, leaks CLI ownership paths, or persistent heap growth; use ios-ettrace-performance for ETTrace capture and JSON.
