Debugging is a narrow discipline: find the smallest reproducer, isolate the cause, fix the actual problem — not a symptom. This pack keeps Claude focused on evidence over speculation.
What you can do with this pack
- Find a minimal reproducer for a bug
- Bisect a regression across commits
- Read a stack trace without guessing
- Debug flaky tests systematically
- Diagnose performance regressions
Skills in this pack
Minimal Repro Finder
Shrink a bug report into a minimal reproducible case. Trigger on 'repro this', 'minimal reproducer', 'how do I reproduce', 'can't reproduce', 'repro steps', or when the user has a bug and needs to isolate it.
Stack Trace Reader
Read and interpret stack traces, error logs, and crash reports. Trigger on 'read this stack trace', 'what does this error mean', 'interpret this log', 'crash report', or when the user pastes an error and wants a diagnosis.
Flaky Test Debugger
Diagnose and fix flaky tests. Trigger on 'flaky test', 'intermittent failure', 'test fails sometimes', 'sporadic failure', or when the user has a test that passes and fails unpredictably.

FAQ
What is a Claude skill?
A Claude skill is a folder containing a SKILL.md file. It tells Claude when to trigger the skill and how to execute the task. Skills live inside your Claude account once uploaded.
Do these work on Free, Pro and Max plans?
Yes, as long as code execution is enabled. On Team and Enterprise plans, an admin needs to enable skills at the organisation level first.
Can I edit the skills?
Yes — the skills are plain markdown files. Open SKILL.md in any editor and change the description, steps, templates, or output format to match how you work.
Do I need all the skills in the pack?
No. Upload only the ones you'll use. Too many active skills makes Claude less precise about which one to pick.
