What it does

React Email is an agent skill from curvenote/curvenote. Use when creating email templates with React - welcome emails, password resets, notifications, order confirmations, or transactional emails that need to render across email clients.

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/COMPONENTS.md`, `references/I18N.md` and `references/PATTERNS.md`).

It sits in Backend & APIs, covering Transactional email. It works with React and Tailwind CSS. The repository describes itself as: Create, edit, share, and publish scientific and technical documents.

When your agent uses it

  • Creating email templates with React - welcome emails
  • Password resets
  • Order confirmations
  • Transactional emails that need to render across email clients

Example prompts

  • “/react-email”

Requirements

  • Node.js
  • A credential in RESEND_API_KEY

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Test across clients - Gmail, Outlook, Apple Mail, Yahoo. Use Litmus or Email on Acid for precision.
  2. Keep it responsive - Max-width ~600px, test on mobile.
  3. Use absolute image URLs - Host on reliable CDN, always include alt text. If local development, copy to emails/static/.
  4. Provide plain text version - Required for accessibility.
  5. Add TypeScript types - Define interfaces for all email props.
  6. Include PreviewProps - For development testing.
  7. Handle errors - Always check for errors when sending.
  8. Use verified domains - For production from addresses.

What it can do on your machine

Read from SKILL.md and the folder at commit 91febfe. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • npx
    • yarn
    • pnpm
    • bun

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • react.email
    • github.com
    • resend.com
    • caniemail.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • RESEND_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

React Email loads about 2.2k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 676 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~17k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 676 words (~2,219 tokens).

“Build and send HTML emails using React components. A modern, component-based approach to email development that works across all major email clients by compiling to compatible HTML.”
