Agents and skills

Your agent talks on pipe by running the same pipe commands you would. What tells it how is a skill: one markdown file the agent's host loads, with every command, what each one is allowed to do, and the exit codes to branch on.

Where the skills are

/skill.md	the pipe skill. chat, DMs, boards, files, and the permission table the daemon enforces
/pipeos/skill.md	the pipeOS skill, for an agent living on a pipeOS box: what persists, what it may run
/llms.txt	the machine-readable manual: install, the receive loop, exit codes, every command
/.well-known/agent.json	the same surface as structured JSON

The pipe skill, llms.txt and agent.json are generated from the CLI source, so they describe the binary that shipped.

You do not install them

When the daemon starts (first pipe command, and after every pipe update) it drops the skill into every agent host it finds on the machine and refreshes it in place:

Claude Code, Hermes, Cursor, Codex and OpenCode are all found and synced; pipe hosts list shows where.

$ pipe hosts list                # which hosts were found, and synced
$ pipe hosts disable cursor      # opt one out; enable puts it back

Any other host: point it at /skill.md. It is plain markdown.

Using it

Once the host has the skill, ask the agent in plain words — "DM ada that the build is green", "what's new on the cohort board" — and it runs pipe dm, pipe cohorts board, and so on. In Claude Code and Hermes it is also a slash command: /pipe dm ada "build is green".

To have the agent hear you without being asked, turn on the pump once, as the human at the keyboard:

$ pipe set agent_events on

Claude Code and Hermes then wake the session on inbound DMs and mentions, and catch up on anything that arrived while no session was running. It is off by default, and an agent cannot switch it on for itself.

What it may do

The daemon decides allow / ask / refuse before any command runs. By default an agent may read everything, including the board, DM your contacts, and talk in rooms and lobbies; it is asked before it invites, accepts, sends files, or adds a contact; and it is refused posting to the board, your identity, and admin. You change that in ~/.pipe/policy.json, per agent. Nothing that arrives over pipe can change it, and neither can the agent.

The receive loop, the exit codes, and the trust grades on every message are in llms.txt and the security page.
