# SumUp Skills

[![Documentation][docs-badge]](https://developer.sumup.com)
[![License](https://img.shields.io/github/license/sumup/sumup-go)](./LICENSE)

</div>

A collection of [Agent Skills](https://agentskills.io/home) for building SumUp payment integrations across card-present (terminal) and card-not-present (online) checkout flows.

## Installing

These skills work with agents that support the Agent Skills standard, including Claude Code, Cursor, Gemini CLI, OpenCode, OpenAI Codex, and Pi.

### Claude Code

Install using the plugin marketplace:

```bash
/plugin marketplace add sumup/sumup-skills
/plugin install sumup@sumup
```

### Cursor

Install from the Cursor Marketplace or add manually via **Settings > Rules > Add Rule > Remote Rule (Github)** with `sumup/sumup-skills`.

### Gemini CLI

Install the extension from GitHub:

```bash
gemini extensions install https://github.com/sumup/sumup-skills --ref=main
```

### OpenAI Codex

Install using the Codex plugin marketplace:

```bash
codex plugin marketplace add sumup/sumup-skills
```

### Kiro

Import this repository as a custom power from Kiro: **Powers > Add Custom Power > Import power from GitHub**.

For local testing, use **Import power from a folder** and select this repository root.

### Agent Skills Discovery

Agents and tools that support the [Agent Skills Discovery RFC](https://github.com/cloudflare/agent-skills-discovery-rfc) can discover the SumUp skills from:

`https://developer.sumup.com/.well-known/agent-skills/index.json`

Use this URL in clients that accept a discovery index or start from `https://developer.sumup.com` when the client discovers well-known skill indexes automatically.

### Clone / Copy

Clone this repo and copy the skill folders into the appropriate directory for your agent:

| Agent | Skill Directory | Docs |
|-------|-----------------|------|
| Claude Code | `~/.claude/skills/` | [docs](https://code.claude.com/docs/en/skills) |
| Cursor | `~/.cursor/skills/` | [docs](https://cursor.com/docs/context/skills) |
| Gemini CLI | `~/.gemini/extensions/` | [docs](https://geminicli.com/docs/extensions/) |
| OpenCode | `~/.config/opencode/skills/` | [docs](https://opencode.ai/docs/skills/) |
| OpenAI Codex | `~/.codex/skills/` | [docs](https://developers.openai.com/codex/skills/) |
| Pi | `~/.pi/agent/skills/` | [docs](https://github.com/badlogic/pi-mono/tree/main/packages/coding-agent#skills) |

## Skills

Install using the `npx skills` CLI:

```bash
npx skills add https://github.com/sumup/sumup-skills
```

Skills are contextual and auto-loaded based on your conversation. When a request matches a skill's triggers, the agent loads and applies that skill.
