Jan 31, 2020Eugenp/Tutorials: Just Announced – “Learn Spring Security OAuth”3 points

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 31,542 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

3 rules. About 0 are common, 0 are distinctive, and 3 are 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.
3
Very specific
Tied to their project's names, files or tools. Probably skip.

Common
Distinctive
Very specific

Very specific:
Run the simulator with mvn -pl common cn1:run.
line 19
Very specific:
Run tests with mvn -pl common cn1:test (on Linux CI use xvfb-run -a).
line 20
Very specific:
When in doubt, open .agent-skills/codename-one/SKILL.md and follow the reference table at the bottom.
line 23

≈ “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.

Keep what fits and drop the rest. Your version, ready for your agents.

Files

AGENTS.md

Start here: .agent-skills/codename-one/SKILL.md
Topical references: .agent-skills/codename-one/references/
Runnable utilities (Java 17 single-file source mode): .agent-skills/codename-one/tools/

Tool integrations (Claude Code, Cursor, etc.) may also pick this skill up via their own conventions; the canonical source of truth is .agent-skills/.

Quick orientation for an agent

App source lives in common/src/main/java/.
Theme/styling lives in common/src/main/css/theme.css (Codename One CSS — a deliberate subset, see .agent-skills/codename-one/references/css.md).
Run the simulator with mvn -pl common cn1:run.
Run tests with mvn -pl common cn1:test (on Linux CI use xvfb-run -a).
Native cloud builds use mvn -pl <ios|android|javascript|javase> package -Dcodename1.platform=... -Dcodename1.buildTarget=....

When in doubt, open .agent-skills/codename-one/SKILL.md and follow the reference table at the bottom.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

It worked
Partly
It didn't

What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

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.
