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 repository4 other files it gives its agents.

The file
We split this AGENTS.md into the rules it gives an agent
1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.

No maintenance scan in a hook.
≈ “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.

Rules
- Preserve user changes. No destructive Git.
- Smallest change. Tests for behavior. ADR for durable design decisions.
- Public files: no private paths, credentials, PIDs, transcripts or host-only claims.
- Portable core first. Third-party CLIs are detected, never silently installed.
- Hook code receives JSON, returns JSON or nothing, and never changes approval, sandbox or stop ownership.
- No maintenance scan in a hook.
synx doctoris manual-only. - One controller; workers get one capsule, one oracle, zero or one skill and a compact evidence result. Three independent workers maximum by default.
Product boundary
minimal: CLI/ledger only.lean: compact host default, prompt gate, session guard and optional routing/projection CLIs.teams: Lean plus Claude's worker-capsule hook; no automatic fan-out.heavy: opt-in graph/large-context tools for one session.
Codex and Claude use merged JSON hooks plus compact global defaults. Hermes
uses a managed block in an existing SOUL.md; GG Coder uses the home
AGENTS.md; both retain installed skills for explicit full loading. Verify
active configuration with the doctor; files on disk are not proof.

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.
