Use early when debugging a medium or hard bug, especially when tests alone may not reveal the real runtime failure. Trigger this before extended TDD iteration when a bug involves runtime state, ordering, persistence, streaming, concurrency, UI/manual reproduction, external services, or when a red or newly passing test may not model the real issue. Skip only when the root cause is already directly proven by a stack trace or deterministic test that exercises the real runtime path.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'debugging-difficult-bugs' ] || [ -L ~/.agents/skills/'debugging-difficult-bugs' ]; then echo 'A skill folder named debugging-difficult-bugs already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mastra-ai/mastra' "$d" && git -C "$d" checkout --quiet '43d1e9c16d6681a66636e318c34118597911f7c5' -- '.claude/skills/debugging-difficult-bugs' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/debugging-difficult-bugs' ~/.agents/skills/'debugging-difficult-bugs' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'debugging-difficult-bugs' ~/.claude/skills/'debugging-difficult-bugs' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
