What it does

Metamask Agent Workflows is an agent skill from nirholas/three.ws. Use when the user needs to perform multi-step operations with the MetaMask Agentic CLI such as onboarding, login, swapping tokens, bridging across chains, opening/closing/modifying perpetual positions, prediction market trading, Aave V3 lending and borrowing, or troubleshooting CLI issues.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 25 other files, including scripts (for example `scripts/amount_to_hex.py`, `workflows/aave-borrow.md` and `workflows/aave-collateral.md`).

It sits in Business, Finance & HR, covering Banking and insurance and Trading and backtesting. The repository describes itself as: Open-source platform for 3D AI agents. Turn text or a photo into a rigged, animated GLB avatar, give it an LLM brain, memory and a wallet, and embed it anywhere with one web… The licence is MIT.

When your agent uses it

  • The user needs to perform multi-step operations with the MetaMask Agentic CLI such as onboarding
  • Swapping tokens
  • Bridging across chains
  • Opening/closing/modifying perpetual positions

Example prompts

  • “/metamask-agent-workflows”

Requirements

  • Python 3
  • Node.js

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Version compatibility
  2. Authentication

What it can do on your machine

Read from SKILL.md and the folder at commit 238ef60. 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 1 file in scripts/ (Python, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • npm
    • npx

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

  • Network

    No URLs in SKILL.md. Its commands use npm and npx, 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

Metamask Agent Workflows loads about 1.1k tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 395 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

Preflight

Run these checks before the first CLI operation in a session, in order.

Show full SKILL.md (207 more words)Show less
1. Version compatibility

This skill is written for @metamask/agentic-cli v1.0.0 (see cliVersion in the frontmatter). Check the installed version:

bash
mm --version

The installed version is the value after @metamask/agentic-cli/ (e.g. @metamask/agentic-cli/1.0.0 darwin-arm64 node-v24.14.1). Compare its major.minor against the pinned cliVersion. Optionally check the latest published version (best-effort; skip silently on network failure):

bash
npm view @metamask/agentic-cli version

If the installed major.minor differs from the pinned cliVersion, or the installed version is behind the latest release, warn the user once and continue:

Version mismatch: installed CLI <installed>, this skill is pinned to 1.0.0, latest release is <latest>. Command syntax in this skill may be inaccurate until they are aligned. Update the CLI with npm install -g @metamask/agentic-cli@latest, then re-install the skills with npx skills add metaMask/agent-skills.

Run this check once per session. Do not block operations on it.

2. Authentication
bash
mm auth status

If the user is not authenticated, follow workflows/onboarding.md for first time setup, or workflows/login.md for login.

Command Discovery

Before constructing any command, run mm <command> --help to confirm the exact flags, syntax, and defaults. Do not guess flags from memory.

Output Rules

  • Route silently. Do not announce which workflow you are loading.
  • Surface errors from commands verbatim. Do not mask or reword them.
  • If a command fails, check mm <command> --help and guide from there.
