AGENTS.md0 starsChanged 4 months agoMITView on GitHub
This repository publishes reusable Spec-Driven Development templates and agent workflows. The four supported workflows are add-spec, update-spec, implement-spec, and review-spec. Validate every changed canonical skill with the active skill-authoring environment. Do not commit while validation is failing.
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.
In this repository7 other files it gives its agents.

The file
We split this AGENTS.md into the rules it gives an agent
9 rules. About 1 is common, 3 are distinctive, and 5 are very specific to this project.
≈1
Common · estimate
Many files like this have a rule of this kind.
≈3
Distinctive · estimate
This author's own choices. Worth a look.
5
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- could be automatic: a setting could enforce it
- Very specific: line 7
Treat skills/ as the canonical workflow source.
- Very specific: line 8
Keep each commands/<name>.md file identical to its matching skills/<name>/SKILL.md.
- Very specific: line 9
Keep .claude/skills/ linked to the canonical skill folders.
- Very specific: line 10
Keep .claude/commands/ synchronized with the four command contracts.
- Very specific: line 11
Keep skills/add-spec/assets/ identical to templates/feature-spec/.
- Distinctive: line 12
Keep AGENTS.md and CLAUDE.md identical.
- Common: line 21
Do not add private URLs, credentials, customer names, or internal project details.
- Distinctive: line 22
Do not weaken scope, task-size, ownership, traceability, proof, or verification gates to make a workflow appear complete.
- Distinctive: line 23
Keep the example small and anonymized.
≈ “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.

Repository Instructions
This repository publishes reusable Spec-Driven Development templates and agent workflows.
Canonical Resources
- Treat
skills/as the canonical workflow source. - Keep each
commands/<name>.mdfile identical to its matchingskills/<name>/SKILL.md. - Keep
.claude/skills/linked to the canonical skill folders. - Keep
.claude/commands/synchronized with the four command contracts. - Keep
skills/add-spec/assets/identical totemplates/feature-spec/. - Keep
AGENTS.mdandCLAUDE.mdidentical. - Keep
templates/AGENTS.mdandtemplates/CLAUDE.mdidentical.
The four supported workflows are add-spec, update-spec, implement-spec, and review-spec.
Change Boundaries
- Inspect the working tree before editing and preserve unrelated changes.
- Preserve tool-neutral workflow rules unless a file is explicitly an adapter.
- Do not add private URLs, credentials, customer names, or internal project details.
- Do not weaken scope, task-size, ownership, traceability, proof, or verification gates to make a workflow appear complete.
- Keep the example small and anonymized.
Verification

git diff --checkValidate every changed canonical skill with the active skill-authoring environment. Do not commit while validation is failing.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

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.
