## Agent Skills for building on Opencals

Most integrations are now written inside an AI coding agent. So we shipped
**Agent Skills** that give those agents ground-truth knowledge of the Opencals
API and SDK — real method names, argument shapes and flows, no guessing. They
follow the open [Agent Skills](https://code.claude.com/docs/en/skills) standard
and work in Claude Code, Cursor, OpenAI Codex, Gemini CLI and more.

Two skills, in one public repo
([github.com/letsopencals/skills](https://github.com/letsopencals/skills)):

* **`opencals-storefront-api`** — the ground-truth reference: availability (slots
  and ranges, custom durations), carts and expiry, appointments, checkout
  (addresses, marketing consent), customer accounts, guests and attendees,
  discounts (automatic, codes, balance credit), reschedule/cancel, and rate
  limiting.
* **`opencals-build-booking-site`** — builds a whole booking website: pick an
  official template, scaffold, wire it up, rebrand, deploy.

Install in Claude Code:

```
/plugin marketplace add letsopencals/skills
/plugin install opencals@opencals
```

Also new:

* A dedicated **[AI Agents](/docs/ai-agents/overview.md)** section in the docs, with
  per-tool install instructions (including v0 / Lovable / Bolt).
* Machine-readable docs at **[llms.txt](https://opencals.com/docs/llms.txt)** and
  **[llms-full.txt](https://opencals.com/docs/llms-full.txt)** for agents that
  consume docs directly.
