Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.
Of the AGENTS.md files we read, the 31,774 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.

The file
We split this AGENTS.md into the rules it gives an agent
4 rules. About 0 are common, 3 are distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈3
Distinctive · estimate
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
- Very specific: line 21
Every skill ships evals/scenarios.json with at least three scenarios and at least one mode: static (tool-free) scenario.
- Distinctive: line 26
Before proposing a change, run and paste the output of:
- Distinctive: line 33
Do not add a skill that is only a prompt.
- Distinctive: line 35
Do not add anything referencing an employer's internal systems.
≈ “Common” is an estimate: at least 1 in 5 of the 40,246 AGENTS.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

If you are using these skills
- Load a skill only when its
descriptionmatches the task. Descriptions are written as "use when …" triggers on purpose. code-quality-gateruns external tools (git,python3,cqa-analyzer). If the analyzer is missing the wrapper exits 3 with an install hint — relay that to the user. Never report findings you did not obtain from a real run.source-grounded-claimsapplies to your own output. If you cite a source, you opened it. If you did not, sayunverifiedand keep confidence below 80%.
If you are changing this repository
- One directory per skill under
skills/.namein the frontmatter must equal the directory name. Frontmatter keys are limited to the spec set (name,description,license,compatibility,metadata,allowed-tools); anything else goes undermetadata. - Every skill ships
evals/scenarios.jsonwith at least three scenarios and at least onemode: static(tool-free) scenario. Scenarios describe observable behaviour, not vibes. - Scripts are standard-library only and must fail loudly with an actionable message. No network calls.
- Before proposing a change, run and paste the output of:
Both must pass. CI runs the same two commands.python3 scripts/validate.py && python3 -m unittest discover -s tests - Bump
metadata.versionin the skill you changed andversionin.claude-plugin/plugin.jsonwhen behaviour changes. - Do not add a skill that is only a prompt. A skill earns a slot here by being backed by a runnable tool or by scenarios that have actually been exercised.
- Do not add anything referencing an employer's internal systems. This repository is public.
Does it work?

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.
