This repository is ai-engineer, a portable skill pack (home: https://rajeshpraharaj.com/). Skills must work in any coding agent that loads a SKILL.md folder (name + description frontmatter, markdown body).
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 31,843 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
5 rules. About 0 are common, 2 are distinctive, and 3 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈2
Distinctive · estimate
This author's own choices. Worth a look.
3
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 10
Do not add host-only frontmatter (when-to-use, argument-hint, disable-model-invocation, model, allowed-tools).
- Distinctive: line 11
Do not name host products, host tools, or host slash commands in skill bodies.
- Distinctive: line 12
Write procedures for one agent with a filesystem, a shell, and (usually) git.
- Very specific: line 13
Keep each SKILL.md under 500 lines.
- Very specific: line 18
Always-on defaults live in templates/AGENTS.md.
≈ “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.

Working on this pack
This repository is ai-engineer, a portable skill pack (home: https://rajeshpraharaj.com/). Skills must work in any coding agent that loads a SKILL.md folder (name + description frontmatter, markdown body).
Format
- One directory per skill under
skills/<name>/. namein frontmatter must match the directory name.- Frontmatter fields allowed:
name,description,license,metadata. Optionalcompatibilityonly for real environment needs (e.g.git). - Do not add host-only frontmatter (
when-to-use,argument-hint,disable-model-invocation,model,allowed-tools). - Do not name host products, host tools, or host slash commands in skill bodies.
- Write procedures for one agent with a filesystem, a shell, and (usually) git.
- Keep each
SKILL.mdunder 500 lines. Put long checklists and copy-templates inreferences/. descriptionmust say what the skill does and when to use it (max 1024 characters).
One home per fact
- Always-on defaults live in
templates/AGENTS.md. Keepskills/explore-codebase/references/agents-template.mdbyte-identical (python3 scripts/validate.pychecks). - Quality checks and secret-file patterns live in
skills/engineering-bar/SKILL.md. - Other skills point at those by name. Do not paste them in full.

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.
