Debugging

verification-loop is a Claude Code verification workflow for checking builds, types, lint, tests, security, and diffs after code changes. This verification-loop skill is useful before PRs and after refactors when you want a structured post-change guide instead of a generic prompt.

gateguard is a fact-forcing pre-action gate for Claude workflows. It blocks the first Edit, Write, or Bash attempt, then requires concrete investigation of importers, schemas, user instructions, and related files before allowing changes. Use this gateguard guide to reduce guessing and improve first-pass edits.

The cpp-testing skill helps you write, run, and debug C++ tests with GoogleTest, GoogleMock, CMake, and CTest. Use it for coverage, flaky-test fixes, sanitizer-backed diagnostics, and practical cpp-testing usage in modern C++ projects.

Learn the agentic-engineering skill for eval-first execution, task decomposition, model routing, and safer workflow automation with regression checks.

error-handling-patterns helps teams choose exceptions vs Result types, classify failures, propagate context, and design graceful degradation for more reliable APIs and services.

anti-reversing-techniques is a reverse-engineering skill for authorized malware analysis, CTF work, packed binary triage, and security audits. It helps you identify anti-debugging, anti-VM, packing, and obfuscation patterns, then choose a practical analysis workflow using the core skill and advanced reference.

fuzzing-obstacles helps you patch a target program so fuzzers can bypass checksums, global state, validation gates, and other blockers. Use this fuzzing-obstacles skill to make a System Under Test more fuzzable while keeping production behavior intact. It’s a practical guide for Security Audit workflows and deeper coverage.

dwarf-expert helps you inspect DWARF v3-v5 debug info, read DIE trees and attributes, verify data integrity, and review code that parses or emits DWARF. Use the dwarf-expert skill when you need accurate, evidence-based answers for compiled binaries, debug sections, or backend development tooling.

The wp-playground skill helps you create disposable, reproducible WordPress Playground environments for plugin and theme testing, version switching, blueprints, snapshots, and isolated debugging. It supports browser or CLI workflows via @wp-playground/cli and is especially useful for backend development, QA, and controlled issue reproduction.

react-native-best-practices is a practical React Native performance optimization guide for slow startup, dropped frames, heavy renders, memory leaks, bundle bloat, and animation jank. Use it when you need evidence-backed fixes for Hermes, bridge overhead, FlashList, native modules, or profiling a release regression.

The kaizen skill guides small, safe code improvements for refactoring, architecture, workflow fixes, error handling, and validation. It favors iterative changes, design-time prevention, and minimal scope. Use it when you want a practical kaizen guide that improves code without over-engineering.

Use the playwright skill to automate a real browser from the terminal with a wrapper script and `playwright-cli`. It fits browser automation tasks like navigation, form filling, screenshots, snapshots, extraction, and UI-flow debugging. Check `npx`, install the skill, set `PWCLI`, then follow the CLI-first workflow.

react-useeffect is a practical React guide for deciding when useEffect is needed, spotting anti-patterns, and choosing better alternatives like render logic, event handlers, useMemo, key resets, or cleaned-up fetch Effects.

pua-ja is a Japanese-language escalation skill that pushes stalled agents to investigate harder, use tools before asking users, and verify results after repeated failures. Best for teams that want a trigger-based behavior layer for debugging, research, writing, and pua-ja for Context Engineering.
