Installing these skills for a user? Follow INSTALL.md instead of this file. This file is for agents that are editing this repository. Then update the matching portable/zh-CN/<name>.md so the Chinese version says the same thing. When releasing, bump metadata.version in every skill and version in both .claude-plugin/*.json together; the validator checks that they match.
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
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.

- Very specific: line 25
When releasing, bump metadata.version in every skill and version in both .claude-plugin/*.json together.
- Very specific: line 30
Every skill mirrors the user's language, never invents facts about the user's world, and uses [placeholders] for facts it doesn't have.
≈ “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.

Layout
skills/<name>/SKILL.md: the skills, in the open Agent Skills format. Frontmatter:name(matches the folder),description(≤ 1024 characters, no:sequences, says what the skill does and when to trigger it, including Chinese trigger phrases),license,metadata.version.skills/<name>/references/: detail loaded on demand. Keep eachSKILL.mdbody under 500 lines.portable/en/: generated single-file prompts for chat apps. Never edit by hand.portable/zh-CN/: hand-maintained Chinese versions of the portable prompts.site/index.html: the GitHub Pages template.scripts/build-site.mjsinjects the portable prompts and writes the site to_site/(not committed)..claude-plugin/: Claude Code plugin and marketplace manifests.
After changing a skill
node scripts/build-portable.mjs # regenerate portable/en
node scripts/validate.mjs # must pass; CI runs the same checkThen update the matching portable/zh-CN/<name>.md so the Chinese version says the same thing.
When releasing, bump metadata.version in every skill and version in both .claude-plugin/*.json together; the validator checks that they match.
Writing style for skills
- Imperative, specific and short. Tell the model exactly what to output and in what shape.
- Every skill mirrors the user's language, never invents facts about the user's world, and uses
[placeholders]for facts it doesn't have. - Hard on the argument, never on the person.

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.
