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 31,774 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 repository57 other files it gives its agents.

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 11
Read and follow .cursor/skills/manage-stack/SKILL.md.
- Very specific: line 12
Prefer the repo-maintainer agent (.cursor/agents/repo-maintainer.md) for a bounded catalog edit.
- Distinctive: line 20
Do not invent a parallel workflow when a skill, agent, or rule already covers the work.
- Distinctive: line 63
Do not commit or push unless asked.
- Very specific: line 71
No employer-owned content, secrets, or personal paths.
≈ “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.
Files
levistack
One source tree of skills, rules, subagents, commands, and hooks for Claude Code, Cursor, Codex, and the skills CLI. CLAUDE.md is a symlink to this file.
Human install steps and the skill-group table live in README.md.
Before you change anything
Maintaining this repository (anything under the catalog tree or under .cursor/):
- Read and follow
.cursor/skills/manage-stack/SKILL.md. - Prefer the
repo-maintaineragent (.cursor/agents/repo-maintainer.md) for a bounded catalog edit.
Using the published catalog (explore, plan, implement, review in this or another repo):
- Load the skill whose
descriptionmatches the task (skills/<group>/<skill>/SKILL.md). - Delegate to a subagent when its
descriptionfits; roster and flow:docs/agents/README.md. - Apply rules from
rules/(Cursor:generated/cursor/rules/after sync). Project sessions in this repo also load.cursor/rules/(for examplemanage-stack.mdc).
Do not invent a parallel workflow when a skill, agent, or rule already covers the work.
Two write surfaces
| Surface | What it is | You edit |
| Catalog | Shipped by the plugins and npx skills add | skills/, agents/, rules/, commands/, hooks/ |
| Project agent tree | How agents work in this repo only | .cursor/agents/, .cursor/rules/, .cursor/skills/ |
Claude Code reads .claude/agents, .claude/rules, and .claude/skills as directory symlinks to .cursor/. npm run sync recreates them. Never add stack tooling under .claude/; change .cursor/ instead.
Catalog rules are authored as rules/<topic>/*.md. Sync writes Cursor .mdc files to generated/cursor/rules/ (see .cursor-plugin/plugin.json). Only alwaysApply: true files in rules/core/ feed the session-start hook (hooks/README.md).
Commands
Requires Node ≥ 20.
npm run sync # manifests, README group table, hooks.json, .claude → .cursor symlinks
npm run check # sync --check, validate, tests
npm run validate
npm test
npm run check:publish # strict; run before making the repo publicAfter editing a catalog skill or agent:
node skills/agent-authoring/create-agent/scripts/lint.mjs skills/<group>/<name>
node skills/agent-authoring/create-agent/scripts/lint.mjs agents/<name>.mdLocal dev (optional): ./scripts/link-skills.sh symlinks catalog skills into ~/.claude/skills and ~/.agents/skills. Statusline: node scripts/install-statusline.mjs (see statusline/README.md).
Verify before reporting done
npm run sync && git diff --exit-code # fail = generated output changed; stage it with your source edit
npm run validate
npm test
claude plugin validate . --strict # when plugin manifests or the tree changedDo not commit or push unless asked.
Boundaries
- Edit only catalog paths above, plus
docs/agents/README.mdwhen the agent roster changes,upstream.jsonwhen an upstream skill is added or removed, and.cursor/for stack tooling. - Upstream skills (
upstream.json) live in their own repos. Sync lists them in the marketplace as GitHub sources and as dependencies of the root plugin. Edit them in their own repo, never copy them intoskills/. - Never hand-edit
.claude-plugin/,.cursor-plugin/,.codex-plugin/,.antigravity-plugin/, the rootplugin.json,skills/<group>/.claude-plugin/,generated/,hooks/hooks.json, or the generated tables inREADME.mdandhooks/README.md. Runnpm run sync. - Skill folder name = frontmatter
name.descriptionis one quoted line, ≤ 1024 characters, and says when to use the skill. - No employer-owned content, secrets, or personal paths. No repo-root
THIRD_PARTY.md; keep import licenses andUPSTREAM.mdbeside copied code.
Where to look
| I want to… | Look at… |
| Add or change a shipped skill | skills/<group>/<name>/SKILL.md plus that group's DESCRIPTION.md; follow manage-stack |
| Add or change a catalog subagent | agents/<name>.md, docs/agents/README.md |
| Add or change a rule | rules/<topic>/<name>.md |
| Add a slash command | commands/<name>.md |
| Add or change a hook | hooks/<name>.mjs, hooks/lib/, hooks/README.md |
| Change how this repo is maintained | .cursor/skills/manage-stack/, .cursor/rules/manage-stack.mdc |
| Understand sync / validate | scripts/sync.mjs, scripts/validate.mjs |
| Install or group list | README.md |
Runtime entry points
| Runtime | Reads |
| Skills CLI | skills/**/SKILL.md via npx skills add |
| Claude Code plugin | .claude-plugin/, per-group skills/<group>/.claude-plugin/ |
| Claude Code (this repo) | .claude/{agents,rules,skills} → .cursor/, this file via CLAUDE.md |
| Cursor plugin | .cursor-plugin/ → every skill path listed, agents/, generated/cursor/rules/; or scripts/link-skills.sh --cursor |
| Cursor (this repo) | .cursor/{agents,rules,skills}/ (source) |
| Codex | the Claude marketplace in .claude-plugin/marketplace.json, then .codex-plugin/plugin.json, this file |
| Antigravity | root plugin.json (only name and description are allowed) and .antigravity-plugin/plugin.json, both generated, or scripts/link-skills.sh --antigravity |
| Trae | no plugin format: scripts/link-skills.sh --trae into ~/.trae/{skills,agents,rules} |
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.
