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 31,439 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 repository17 other files it gives its agents.

The file
We split this AGENTS.md into the rules it gives an agent
10 rules. About 0 are common, 10 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈10
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 24
Never use hamburger menus — use a tab bar
- Distinctive: line 25
Never override swipe-from-left-edge back navigation
- Distinctive: line 26
Never hardcode text sizes — support Dynamic Type
- Distinctive: line 27
Never use only color to convey information
- Distinctive: line 28
Never request all permissions at launch
- Distinctive: line 29
Never place primary actions at the top of the screen (outside thumb zone)
- Distinctive: line 30
Never clip content under the status bar, home indicator, or Dynamic Island
- Distinctive: line 31
Never use blocking spinner overlays for loading states
- Distinctive: line 32
Never show splash screen logos — match the first screen of the app
- Distinctive: line 33
Never hide the tab bar during navigation within a tab
≈ “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.

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.
