How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.
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 repository19 other files it gives its agents.

≈ “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.
Keep what fits and drop the rest. Your version, ready for your agents.

SolidCraft: instructions for agents
SolidCraft is a clean-room, pure-Rust parametric 3D CAD app (sketch solver, feature timeline, B-rep kernel, an egui UI that agents drive). This file is a router: the hard rules, then the skill to read for your task. Humans: CONTRIBUTING.md.
Start here
Work: ROADMAP.md, "Where help is wanted most" in CONTRIBUTING.md, issues labelled help wanted, good first issue, needs-triage; architecture in docs/architecture.md. Local plan/ notes are optional.
Hard rules (what enforces each)
- Independent: never copy another product's code, icons, text or templates; never drive or take data from commercial CAD.
skills/solidcraft-ground-rules/SKILL.md. - No GPL/LGPL/AGPL code, not even reading it (OpenCASCADE, FreeCAD, SolveSpace, CadQuery, LibreCAD, QCAD):
cargo xtask licences --check. - Every asset is original or openly licensed with a row in ATTRIBUTION.md; read
assets/AGENTS.mdbefore icon work:cargo xtask assets,cargo xtask icons. - Never crash: no unwrap/expect/panic/unsafe in non-test code, errors are
Result, input is hostile: clippy-D warnings,hostile_params_never_panic. - Model decisions (what an operation does, which bodies it touches, which face or edge a point or name means, depths, nearness) use exact geometry; a mesh is for display, export, previews and mesh bodies (
xtask/mesh-decisions.txtonly shrinks):cargo xtask mesh-decisions. - New kernel cases go to solidcore:
cargo xtask lists. - Everything is a command and programmatic calls never open dialogs:
skills/solidcraft-commands/SKILL.md. - Layering (geom, sketch/kernel/render, doc, io, engine, ui-egui, apps); only
crates/kerneluses truck:cargo xtask layers. - One outer UI container, one camera path (
navigation::handle), colours from theme tokens:cargo xtask ui-containers. - Application code is Rust only and builds for wasm:
cargo xtask wasm,cargo xtask web-offline-test. - The product name is SolidCraft; the old name lives only in
docs/compatibility.md. - Sorted lists (message catalogs,
modlines, languages) stay sorted:cargo xtask lists. Never edit generated files (docs/features.md,THIRD-PARTY-LICENSES.txt) in a PR. - A design-format change is ONE new file in
crates/doc/src/format/pending/:scripts/test-format-pending.sh. - A command has input and output schemas (will become required;
schema/unconverted.txtonly shrinks):skills/solidcraft-commands/SKILL.md. - New UI strings go in
assets/locales/pending/<slug>.json, ATTRIBUTION rows inattribution/pending/<slug>.md:cargo xtask lists. - A changed default keeps the old behaviour behind a preference and fills the PR's
Changes a default:line:pr-checks.yml. - A regression test goes in the area's existing test file, never a per-bug file (#3226).
- Look at open PRs first, claim with a draft PR (lowest number wins), one topic per PR:
skills/solidcraft-contributing/SKILL.md. - A PR's title and first sentence make sense to someone who never saw your chat or the issue:
skills/solidcraft-contributing/SKILL.md. - Code, comments, commit messages and docs are in English, always:
skills/solidcraft-contributing/SKILL.md("Working as an agent"). - Independent work runs in parallel, dependent work stays sequential:
skills/solidcraft-contributing/SKILL.md("Working as an agent"). - Show observable changes with real screenshots or a recording, captured yourself.
- Run
cargo xtask cibefore every commit.cargo xtask skillskeeps this file andskills/honest.

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
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.
