SuperSend TXDocs

Agent Skills

Official Agent Skills for Cursor, Claude Code, Codex, and other clients that support the Agent Skills 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.

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 (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.
