# Runtimes

> Install and run Simmer trading skills from any agent runtime that supports the agentskills.io standard.

Simmer skills are **agent-runtime-agnostic**. Every skill is a portable folder with a `SKILL.md` file following the open [agentskills.io](https://agentskills.io/home) standard — the same format supported by Claude Code, Hermes, Cursor, Codex, and 30+ other clients. Pick whichever runtime fits your workflow; your skill library travels with you.

## Install on your runtime

<Tabs>
  <Tab title="OpenClaw / ClawHub">
    ```bash theme={null}
    clawhub install polymarket-weather-trader
    ```

    Installs the skill into OpenClaw's skill library. After install, your agent can invoke it like any other skill. See the [ClawHub CLI docs](https://clawhub.ai) for the full command reference.
  </Tab>

  <Tab title="Hermes">
    ```bash theme={null}
    hermes skills install skills-sh/spartanlabsxyz/simmer-sdk/polymarket-weather-trader
    ```

    Pulls the skill directly from the [skills.sh](https://www.skills.sh/) index into your Hermes skill folder.
  </Tab>
</Tabs>

<Note>
  Replace `polymarket-weather-trader` with any skill slug from [simmer.markets/skills](https://simmer.markets/skills?ref=docs\&utm_campaign=docs). The install command in the Skill Detail modal on that page is the canonical source — copy-paste it directly.

## Supported runtimes

| Runtime                                    | Status                    | Install command                                                                                                                                                                              |
| ------------------------------------------ | ------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **OpenClaw / ClawHub**                     | ✅ Supported               | `clawhub install <slug>`                                                                                                                                                                     |
| **Hermes**                                 | ✅ Supported               | `hermes skills install skills-sh/spartanlabsxyz/simmer-sdk/<slug>`                                                                                                                           |
| **Claude Code**                            | 🟡 Install syntax pending | Skills are [agentskills.io](https://agentskills.io)-compliant and load correctly once added to a project's skills directory. Official CLI-install flow pending Anthropic's registry rollout. |
| **Cursor**                                 | 🟡 Install syntax pending | Skills load from a project's skills directory per [Cursor's skills docs](https://cursor.com/docs/skills).                                                                                    |
| **Codex**                                  | 🟡 Install syntax pending | Skills compatible per [OpenAI Codex skills docs](https://learn.chatgpt.com/docs/build-skills).                                                                                               |
| **Cline, Goose, OpenHands, Factory, etc.** | 🟡 Install syntax pending | Most are agentskills.io-standard clients — our skills load as-is from a folder; check each runtime's skills guide.                                                                           |

We don't publish speculative install commands — if a runtime isn't explicitly confirmed, the syntax above gets added the moment we verify it end-to-end.

## Why portable skills matter

Before agentskills.io, installing a skill in OpenClaw vs Hermes vs Claude Code meant three different formats, three different packaging steps, and no way to move a strategy across runtimes without re-authoring it. The open standard fixed that: `SKILL.md` + frontmatter is universal, and a well-written skill runs anywhere the format is supported.

For Simmer users, this means:

* **Switch runtimes without losing your setup.** Move from OpenClaw to Hermes and your installed skills come with you.
* **Community skills inherit cross-runtime support automatically.** When a skill is published on ClawHub or skills.sh, it's instantly available in every supported runtime — no per-runtime port.
* **Your strategy is the portable asset.** Runtimes are fungible; the skill folder travels.

## Skill format reference

Every Simmer skill is validated against the official [agentskills.io specification](https://agentskills.io/specification) using the reference validator:

```bash theme={null}
npx skills-ref validate <skill-directory>
```

If you're building your own skill, see [Skills → Building your own](/skills/building) for the Simmer-specific patterns on top of the base spec.
