This project uses Chiltepin: documentation-as-code where a doc is Markdown with typed, fenced YAML blocks, and the files on disk are the single source of truth. When creating or changing any document under docs/*/.md, follow the authoring skill at skills/chiltepin/SKILL.md. It defines the block grammar and the doc#id reference scheme; run node packages/cli/dist/bin.js block <type> for any block's fields and an example. In short: - Prose is plain Markdown; structure goes in typed blocks (e.g. sequence, erd, table, callout, c4,…
We split this copilot-instructions.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.
- Common
- Distinctive
- Very specific
- Very specific: line 8
When creating or changing any document under docs//*.md, follow the authoring skill at skills/chiltepin/SKILL.md.
- Distinctive: line 16
Use only the documented block types and their documented fields — the schemas are strict, so an unknown block or field fails validation.
- Very specific: line 20
Run chiltepin check and fix all diagnostics before finishing.
≈ “Common” is an estimate: at least 1 in 5 of the 3,669 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.

This project uses Chiltepin: documentation-as-code where a doc is Markdown with typed, fenced YAML blocks, and the files on disk are the single source of truth.
When creating or changing any document under docs/**/*.md, follow the authoring
skill at skills/chiltepin/SKILL.md. It defines the block grammar and the doc#id
reference scheme; run node packages/cli/dist/bin.js block <type> for any block's
fields and an example. In short:
- Prose is plain Markdown; structure goes in typed blocks (e.g.
sequence,erd,table,callout,c4,flow,timeline,userstory). Never paste raw HTML or inline SVG. - Use only the documented block types and their documented fields — the schemas are strict, so an unknown block or field fails validation. Bodies are YAML.
- Give a block an
id:when it needs to be referenced; reference it asdoc#id. - Edit the specific block surgically — don't regenerate whole files.
- Run
chiltepin checkand fix all diagnostics before finishing. A change isn't done until it passes.
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 2,297 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.

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.
