# Agent Skills

Official Agent Skills for Cursor, Claude Code, Codex, and other clients that support the [Agent Skills](https://agentskills.io) format.

Skills teach agents how to send with SuperSend TX, install MCP/CLI, and follow email deliverability basics — without stuffing the entire docs corpus into every prompt.

**Index:** [llms.txt](https://docs.supersendtx.com/llms.txt) · [Agent skill notes](./agent-skill.md) · [MCP server](./mcp.md) · [GitHub (public)](https://github.com/Super-Send/supersendtx-skills)

## Available skills

| Skill | When to use |
|-------|-------------|
| **supersendtx** | Send API, `stx_` auth, sandbox rules, domains, SDK / OpenAPI |
| **supersendtx-mcp** | Install and use `supersendtx-mcp` in Cursor or Claude Code |
| **supersendtx-cli** | Terminal flows (`emails`, `domains`, `webhooks`, `suppressions`, …) |
| **email-best-practices** | SPF/DKIM, suppressions, key hygiene, sandbox vs production |

For **React Email** authoring and preview, use React Email’s own tools and skills. Send with SuperSend TX — see [Send React Email](/guides/react-email) (`npm install supersendtx @react-email/render react`).

## Cursor / Claude / Codex

After `npx skills add …`, restart or reload the agent so skill names/descriptions are discovered. The agent loads full `SKILL.md` bodies only when a task matches the skill description.

Prefer:

1. Install **supersendtx** for any send/integration work
2. Add **supersendtx-mcp** when the user wants MCP tools instead of writing HTTP
3. Add **email-best-practices** when reviewing deliverability or production readiness

The dashboard **Get started** page can still generate a personalized setup prompt (API key + sandbox rules) for Cursor or Claude.
