Map Debug

Category: Engineering  ·  Sub-category: testing  ·  Last updated:
lang:pythontype:debug
Structured MAP debugging via task-decomposer, actor, and monitor agents. Use when reproducing a bug, isolating a regression, or diagnosing an error with specialized agents — including failing or flaky tests (pytest AssertionError), crashes and segmentation faults, memory-corruption or memory errors in native/C extensions, intermittent or load-dependent failures (e.g. 500s under load), data-corruption bugs that only appear in production, scripts or hooks that silently exit or produce no output, and any "find the root cause" / "walk me through diagnosing" / "help me investigate" request. Trigger on phrasing like "failing test", "mysterious error", "segfault", "memory error", "intermittently fails", "root cause", "isolate the cause", "debug why", "diagnose", or "investigate the error". Prefer this over generic investigation when the user wants a systematic decompose-reproduce-fix-verify workflow. Do NOT use for greenfield features; use map-plan or map-efficient.

What this skill does

Map Debug is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/map-debug/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when reproducing a bug, isolating a regression, or diagnosing an error with specialized agents — including failing or flaky tests (pytest AssertionError), crashes and segmentation faults, memory-corruption or memory errors in native/C extensions, intermittent or load-dependent failures (e.g.

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Map Debug skill?
Use Map Debug when your Claude Code task falls under the Engineering category — specifically in the testing area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Map Debug" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Map Debug skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Map Debug is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
