How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
3 rules. 0 are common, 2 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 174 edited versions we read keep these.
2
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 9
Use for a concrete report such as an error, wrong result, broken interaction, or measurable slowdown.
- Distinctive: line 13
Write a short ranked list of hypotheses and choose the cheapest observation that can distinguish them.
- Very specific: line 17
Do not mask errors, broaden the rewrite, or claim a root cause without evidence.
“Common” is measured: kept by at least 6 in 10 of the 174 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Diagnose a failure
Use for a concrete report such as an error, wrong result, broken interaction, or measurable slowdown.
- Capture the exact symptom and expected behavior. Inspect logs, recent changes, relevant code, and the environment without exposing secrets.
- Reproduce the failure using the least disruptive path. If it cannot be reproduced, identify what evidence is missing.
- Write a short ranked list of hypotheses and choose the cheapest observation that can distinguish them.
- Trace the failing value or control path to its cause. Do not treat a correlation or a plausible code smell as proof.
- Make a targeted fix, inspect nearby paths for the same cause, and gather evidence that the original symptom is resolved.
Do not mask errors, broaden the rewrite, or claim a root cause without evidence. Run regression tests only when the user asks for testing or verification. This Kratos skill retains the requested diagnose name; upstream currently calls it diagnosing-bugs.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
