Portable repository-scoped skill: Keep Codex, Claude Code, and Hermes workflows aligned through portable skills, explicit runtime adapters, and shared MCP contracts. Defined entirely by SKILL.md. - SKILL.md — canonical definition: frontmatter (name: agent-interop, description), where each runtime discovers skills and MCP settings, and the handoff record fields (objective, scope, assumptions, files changed, tool calls, evidence, unresolved risks, next verification step). - README.md — human signpost. - Claude Code wrapper: .claude/skills/agent-interop/SKILL.md only points back to this file. - Runtime files it…
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 31,700 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 repository47 other files it gives its agents.

The file
We split this AGENTS.md into the rules it gives an agent
3 rules. About 0 are common, 2 are distinctive, and 1 is 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.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 32
Treat .agents/skills/ as the portable, repository-scoped skill library.
- Distinctive: line 36
When a runtime changes where it reads skills or MCP settings, update this file and the "Runtime setup" section of the interoperability doc …
- Distinctive: line 38
Do not encode one runtime's permission model as if another runtime honors it.
≈ “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
AGENTS.md — codomyrmex/.agents/skills/agent-interop
Purpose
Portable repository-scoped skill: Keep Codex, Claude Code, and Hermes workflows
aligned through portable skills, explicit runtime adapters, and shared MCP
contracts. Defined entirely by SKILL.md.
Key Files
SKILL.md— canonical definition: frontmatter (name: agent-interop,description), where each runtime discovers skills and MCP settings, and the handoff record fields (objective, scope, assumptions, files changed, tool calls, evidence, unresolved risks, next verification step).README.md— human signpost.
Dependencies
- Claude Code wrapper:
.claude/skills/agent-interop/SKILL.mdonly points back to this file. - Runtime files it names:
.codex/config.toml(Codex MCP), a project.mcp.jsonfor Claude Code (opt-in fromconfig/claude_code_mcp.example.json), and~/.hermes/config.yaml(fromconfig/hermes_external_skills.example.yaml). - Final step of the composition order in docs/agents/agent-interoperability.md.
- Parent: ../AGENTS.md
Development Guidelines
- Treat
.agents/skills/as the portable, repository-scoped skill library; mirror into runtime-specific folders rather than forking content. - This is the canonical copy; runtime wrappers such as
.claude/skills/agent-interop/stay pointers — change the workflow here. - When a runtime changes where it reads skills or MCP settings, update this file and the "Runtime setup" section of the interoperability doc together.
- Do not encode one runtime's permission model as if another runtime honors it.
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.
