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.
In this repository32 other files it gives its agents.

The file
We split this AGENTS.md into the rules it gives an agent
3 rules. About 0 are common, 1 is distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 5
Use the ruby-rails profile with ruby-core-skills.
- Distinctive: line 8
Keep Rails-specific procedures here and Ruby language patterns in ruby-core-skills.
- Very specific: line 9
Run scripts/validate-skills.sh after registry changes.
≈ “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.
Files
Repository guidance
directory.jsonis the registry. Keep each registered skill path valid.- Continue only work authorized by the user; obtain authorization before beginning additional work or actions that require it.
- Use the
ruby-railsprofile withruby-core-skills; the shared router is inagnostic-planning-skills. - Behavior changes need focused evidence. Reviews, docs, setup, and mechanical changes do not inherit a TDD gate.
- Pause only for production data, security/authorization, deployment, irreversible actions, or unverified external APIs.
- Keep Rails-specific procedures here and Ruby language patterns in ruby-core-skills.
- Run
scripts/validate-skills.shafter registry changes.

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.
