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 31,700 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
Show its rules and text
We split this AGENTS.md into the rules it gives an agent
14 rules. About 0 are common, 11 are distinctive, and 3 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈11
Distinctive · estimate
This author's own choices. Worth a look.
3
Very specific
Tied to their project's names, files or tools. Probably skip.

- Very specific: line 19
Follow the Agent Skills folder format with a required SKILL.md.

Keep names narrow and descriptions discriminating enough for routing.
- Very specific: line 21
Put conditional detail in linked references/ files.

Prefer observable workflows and decision criteria over generic design advice.

Test positive routing, negative routing, and realistic behavior.
- Very specific: line 29
Every released skill declares one provenance class: original, synthesized, adapted, or reference-only.
- Distinctive: line 33
Do not copy paid, source-available, Commons-Clause, redistribution-prohibited, or ambiguously licensed material.
- Distinctive: line 48
Use focused feature branches and reviewed pull requests.
- Distinctive: line 49
Use stacked pull requests only when their dependency is explicit.
- Distinctive: line 50
Run repository validation and inspect generated diffs before committing.
- Distinctive: line 52
Do not merge, publish a release, or connect deployment automation without explicit owner approval.
- Distinctive: line 54
Update documentation in the same PR as any behavior or contract change.
≈ “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.

Agent instructions
This repository is the canonical source for a standalone public library of design Agent Skills.
Source of truth
- Treat the current repository as authoritative; handoffs and memory may be stale.
- Edit canonical source and regenerate derived files. Never hand-edit generated catalog output.
- A directory is not evidence that a skill is supported. Metadata, validation, behavior evidence, and release state must agree.
- Keep DesignMD optional. Every public skill must deliver its core outcome without an account, key, MCP server, private catalog, or hosted service.
Skill authoring
- Follow the Agent Skills folder format with a required
SKILL.md. - Keep names narrow and descriptions discriminating enough for routing.
- Put conditional detail in linked
references/files. Add scripts only for repeated deterministic mechanics and test them. - Prefer observable workflows and decision criteria over generic design advice.
- Test positive routing, negative routing, and realistic behavior.
- Claim agent compatibility only after installation and execution are tested.
Licensing and provenance
- Every released skill declares one provenance class:
original,synthesized,adapted, orreference-only. - Original repository work is MIT-licensed. Adapted files retain all upstream licenses, notices, attribution, and modification markings.
- Do not copy paid, source-available, Commons-Clause, redistribution-prohibited, or ambiguously licensed material.
- Rewriting does not erase attribution or license obligations.
Security and privacy
- Skills must not contain secrets, shared keys, credential-shaped examples, hidden paid calls, telemetry, or undisclosed network behavior.
- Scripts, hooks, installers, and network actions require explicit review and the least authority needed.
- A public skill may describe optional third-party integrations, but it must not silently invoke them.
Working agreement
- Use focused feature branches and reviewed pull requests.
- Use stacked pull requests only when their dependency is explicit.
- Run repository validation and inspect generated diffs before committing.
- Review the exact commit that will be pushed.
- Do not merge, publish a release, or connect deployment automation without explicit owner approval.
- Update documentation in the same PR as any behavior or contract change.

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.
