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 repository13 other files it gives its agents.

The file
We split this AGENTS.md into the rules it gives an agent
1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈0
Distinctive · estimate
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.

- Distinctive
- Very specific
- Very specific: line 17
Update CHANGELOG.md for meaningful 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.

Writing
For anything I read (replies, docs, PR bodies, UI copy): plain words, active voice, one idea per sentence. Periods and commas only, never em dashes. No puffery, no chatbot phrases. Say what a thing does, not how it feels.
UI
Build every app's UI from its own component library: styles live only in src/components/ui/, screens compose those components with no className or style, and /dev/ui shows every one. The standards skill has the full setup.
