# Agent Skills

> Install Aomi's build and transaction skills in an Agent Skills client or Codex.

Aomi publishes two operating procedures in the [`aomi-labs/skills`](https://github.com/aomi-labs/skills) repository:

| Skill                                                                          | What it teaches                                                                                                  |
| ------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------- |
| [`aomi-transact`](https://github.com/aomi-labs/skills/tree/main/aomi-transact) | Drive the npm client CLI through Agent chat, Action review, EVM batch simulation, and explicit wallet execution. |
| [`aomi-build`](https://github.com/aomi-labs/skills/tree/main/aomi-build)       | Turn an API, SDK, or product requirement into a Rust Aomi plugin that you ship as an App.                        |

Skills are markdown instructions and supporting references. Your coding agent reads them and uses the local tools declared by the skill.

## Install

<Tabs>
  <Tab title="Agent Skills clients">
    Install both skills from the canonical repository:

    ```bash theme={null}
    npx skills add aomi-labs/skills
    ```

    This path is intended for Agent Skills-compatible clients such as Claude Code, Cursor, Gemini CLI, and VS Code Copilot.
  </Tab>

  <Tab title="OpenAI Codex">
    Add the repository as a Codex plugin marketplace, then install the `aomi` bundle:

    ```bash theme={null}
    codex plugin marketplace add aomi-labs/skills
    codex plugin add aomi@aomi-skills
    ```

    The bundle contains the `aomi-transact` and `aomi-build` skills.
  </Tab>
</Tabs>

The skills and client CLI update independently. Installing or refreshing a skill does not upgrade a globally installed `aomi` binary.

For transaction work, install or update the npm client separately:

```bash theme={null}
npm install -g @aomi-labs/client@latest
aomi --version
```

`aomi-transact` requires client `0.6.0` or newer. Its first step checks the detected version and can use `npx @aomi-labs/client@latest` when no global binary is available.

## Transaction workflow

Ask your coding agent for a read or transaction in plain language. The skill turns that request into explicit CLI steps:

```bash theme={null}
aomi chat "swap 1 ETH for USDC" \
  --new-session \
  --public-key 0xYourAddress \
  --chain 1
aomi tx list
aomi tx simulate <action-id>
aomi tx sign <action-id>
```

The skill treats a quote or chat answer as different from a pending Action. It lists the current Action before signing and simulates dependent EVM execution Actions together.

Local CLI execution uses the configured wallet key. Account abstraction is prepared in the backend lane. The `--aa` and `--eoa` flags only assert the kind of the pending Action; the skill does not select an AA provider or implementation from the signing command.

## Security boundary

The canonical `aomi-transact` manifest declares `risk_tier: L2` because it can sign and broadcast onchain transactions. Its default permissions are narrow:

* shell commands are limited to `aomi` and `npx @aomi-labs/client@latest`;
* file reads and writes are limited to `~/.aomi/`, with identity files denied;
* network access is limited to `chat.aomi.dev` in the manifest;
* no MCP tools are granted by the skill;
* credential setup and transaction signing require an explicit user request;
* the procedure lists a pending Action and simulates dependent EVM steps before signing.

The CLI can also contact a user-supplied `--rpc-url` during wallet execution. Review that endpoint and the prepared Action before authorizing a signing run.

The skill never invents or echoes a credential value. `aomi secret add` sends a temporary secret value to the Aomi backend and stores only its handle locally, so the backend becomes part of the credential's trust boundary. Persistent per-user App credentials use a separate Account API and never return saved values.

| ------------------ | ---------------------------------------------------------------------------- | --------------------------------------------------------------------- |
| Control plane      | Instructions drive local CLI or build tools.                                 | A Streamable HTTP client calls the hosted Agent or Pipeline resource. |
| Installation       | Install the repository or Codex plugin bundle.                               | Add one MCP URL and complete OAuth.                                   |
| Transaction review | `aomi-transact` reviews and executes a local CLI Action with a local signer. | Agent MCP hands a pending Action to a human wallet surface.           |
| State              | Local CLI records plus backend Agent sessions.                               | Account-owned Agent sessions or stateless Pipeline calls.             |
| Best fit           | Guided transaction procedures and App authoring.                             | Hosted Agent turns or direct Pipeline discovery from any MCP client.  |

You can install both. Their credentials and execution boundaries remain separate.

## Update

Refresh the skills:

```bash theme={null}
npx skills add aomi-labs/skills
```

Then update the CLI independently if you use `aomi-transact`:

```bash theme={null}
npm install -g @aomi-labs/client@latest
aomi --help
```

Use the repository's current `SKILL.md` and references as the authority for the installed procedure. Use [Client CLI commands](/docs/reference/client-cli/commands) for the installed binary's command surface.
