What it does

M0 is an agent skill from coco-research/coco. Use when the user says 'm0', 'm0 status', 'start m0', 'cross-tool memory', 'operational thread', or 'where is my memory stored', or when the M0 daemon or MCP wiring needs attention.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/m0_mcp.py` and `scripts/m0_server.py`).

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: CoCo Super Intelligence is the orchestration layer that turns Claude Code, Cursor, or Codex into an engineering department: a routed advisory board, 226 skills, 386 commands…

When your agent uses it

  • The user says m0
  • Cross-tool memory
  • Operational thread
  • Where is my memory stored

Example prompts

  • “m0 status”
  • “start m0”
  • “cross-tool memory”
  • “/m0”

Requirements

  • Python 3

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Daemon — reachable at $M0 or not.
  2. launchd — whether the job com.coco.m0-backend is loaded and running.

What it can do on your machine

Read from SKILL.md and the folder at commit 6036e9c. 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

    Ships 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    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

M0 loads about 755 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 356 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~755

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); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 356 words (~755 tokens).

“M0 keeps one local operational thread per project: what was done, what was verified, what is next. Any tool can write to it and read it back, so a session that starts cold can continue work another tool began.”

What does M0 do?

A skill your agent uses when the user says 'm0', 'm0 status', 'start m0', 'cross-tool memory', 'operational thread', or 'where is my memory stored', or when the M0 daemon or MCP wiring needs…. M0 is an agent skill from coco-research/coco. Use when the user says 'm0', 'm0 status', 'start m0', 'cross-tool memory', 'operational thread', or 'where is my memory stored', or when the M0 daemon or MCP wiring needs attention.

When should I use M0?

M0 fits situations like: the user says m0; cross-tool memory; operational thread; where is my memory stored.

How do I install M0 in Claude Code?

Run `npx skills add coco-research/coco --skill m0 -a claude-code`. Or copy the skill folder (systems/m0/skills/m0 in coco-research/coco) into .claude/skills/m0 in your project. Claude Code loads it when a task matches its description.

How do I install M0 in Codex?

Run `npx skills add coco-research/coco --skill m0 -a codex`. Or copy the skill folder (systems/m0/skills/m0 in coco-research/coco) into .agents/skills/m0 in your project. Codex loads it when a task matches its description.

Can I use M0 in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add coco-research/coco --skill m0 -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/m0, .gemini/skills/m0, .github/skills/m0 and .opencode/skills/m0 in your project.

What does M0 need to run?

Going by SKILL.md and its folder, M0 needs Python for the scripts in its folder and the command-line tools its instructions call (curl). Our summary lists: Python 3.

Does M0 access the network?

SKILL.md contains no URLs. Its commands use curl, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is M0 safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does M0 use?

M0 has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does M0 use?

About 755 tokens (SKILL.md is roughly 3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to M0?

Skills that share tags, products or a category with M0: MCP Server Builder (anthropics/skills, 180k stars), MCP Server Builder (shareAI-lab/learn-claude-code, 78k stars), MCP Integration for Plugins (anthropics/claude-plugins-official, 37k stars) and Fastmcp Client CLI (PrefectHQ/fastmcp, 28k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
