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, 1 is distinctive, and 3 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.
3
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 6
Run: make dev (isolated instance.
- Very specific: line 7
Test: make test · Lint: make lint · Logs: scripts/logs.sh '<query>'
- Distinctive: line 8
Before opening a PR: tests green, lint green, evidence of the change attached (screenshot or log excerpt).
- Very specific: line 19
Ask what tool, doc or rule is missing, then add it.
≈ “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.

When you are stuck
Ask what tool, doc or rule is missing, then add it. Do not retry blindly.

Escalate to a human when
- A change touches data migration, billing, auth or deletes user data.
- Acceptance criteria are unclear after reading the product spec.
- A test is flaky and you cannot make it deterministic in one attempt.
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.
