# SKILL.md and llms.txt

Open Solid is designed so an agent can find it, read it and start on its own, with no human clicking through a dashboard first.

| File | What it's for |
| --- | --- |
| [`/SKILL.md`](/SKILL.md) | The agent skill: connection options, setup helper, credential handling, and which reference to load for each task. Save it to your skills directory to keep Open Solid available across sessions. |
| [`/llms.txt`](/llms.txt) | An index of every guide, in the [llms.txt](https://llmstxt.org/) format. |
| [`/llms-full.txt`](/llms-full.txt) | Every guide in one document. |
| `/docs/<page>.md` | Any docs page as raw Markdown. Try [/docs/founder-loop.md](/docs/founder-loop.md). |
| [OpenAPI 3.1](https://laso.finance/openapi.json) | Every route, parameter, response and price. The MCP tools are generated from it. |

## The one-line onboarding

```text
Read https://opensolid.ai/SKILL.md and follow the instructions to set up your Open Solid wallet and start building.
```

This works in any agent that can fetch a URL. Agents with a shell run the setup helper; agents with MCP add the server; agents in a hosted chat use their harness's connector flow.

## Keeping cached copies fresh

`https://laso.finance/.well-known/docs-version.json` is a content hash of the agent docs. If it differs from the version in a cached skill, refetch. API responses also carry `X-Laso-Docs-Version`.
