Where files are headingNew Copilot instructions files have more rules about branches and pull requests, and fewer about code style.
Of the Copilot instructions files we read, the 2,336 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.

≈ “Common” is an estimate: at least 1 in 5 of the 3,779 Copilot instructions 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.

Public API changes
- Check every diff for public API additions, removals, renames, and modifications, including exports, public members, signatures, types, configuration options, defaults, and observable behavior. Additive and non-breaking changes must also be called out.
- Whenever a public API changes, include a prominent Public API change warning in the PR description. List each affected package and API, what changed, and a clear reason why the change is necessary and intentional. Code comments, commit messages, or review discussions alone are not sufficient justification.
- State the compatibility impact of each change. For breaking changes, include migration guidance for existing callers.
- During review, explicitly flag public API changes. Report missing or unclear rationale in the PR description as [HIGH]; do not assume an API change was intentional.

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.
