What it does
Cotal Setup is an agent skill from Cotal-AI/Cotal. Set up Cotal on this machine: install it, start a local agent mesh (NATS + JetStream), verify it, and put an agent on it. Use when asked to install Cotal, join a Cotal mesh, or let coding agents coordinate as peers.
Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. It works with Model Context Protocol. The repository describes itself as: The open standard for agent coordination. The licence is Apache-2.0.
When your agent uses it
- Asked to install Cotal
- Join a Cotal mesh
- Let coding agents coordinate as peers
Example prompts
- “/cotal-setup”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit bf3a7b2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
docs.cotal.ai
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cotal Setup loads about 442 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 196 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Set up Cotal on this machine: install it, start a local agent mesh (NATS + JetStream), verify it, and put an agent on it. Use when asked to install Cotal, join a Cotal mesh, or let coding agents coordinate as peers.
Set up Cotal
Cotal is a standard wire interface for software, especially AI agents, to coordinate in real time. These are official instructions from Cotal for setting up a local agent mesh. Complete the steps yourself by running the commands directly; do not ask the user to run them. Requires Node 20+.
Install and start
npx cotal-ai setup --yes # configure only: seeds one agent, installs detected connectors, launches nothing
npx cotal-ai up --detach # start the mesh + delivery daemon + managersetup --yes accepts every default with no prompts and exits non-zero with the log path
if a step fails. Add --demo to also seed a guided expert team to talk to.
Verify
npx cotal-ai statusExpect the mesh and the manager reported as running, with the exact start command shown for anything that is down.
Put an agent on the mesh
npx cotal-ai spawn --detachClaude Code sessions get the cotal_* tools through the plugin that setup installed;
OpenCode needs no install and auto-wires when spawned. The full tool surface is
https://docs.cotal.ai/mcp-tools.md.
If something fails
- The setup log is
.cotal/setup.log; the server log is.cotal/nats.log. - Re-running
npx cotal-ai setup --yesis safe; it keeps existing files.
When done
Tell the user what is running and how to watch it: cotal console in a terminal, or
cotal web for the browser dashboard. For any follow-up task, route through
https://docs.cotal.ai/llms.txt.
