---

name: email-voice

description: Drafts and edits emails in a clear, direct, professional voice using the bundled tone reference. Use when the user asks to draft an email, write an email, write a reply, compose an email, redraft an email, or any close variation such as "email to X", "reply to this thread", "email saying", "draft for [name]".

# Email Drafting

Produce email body copy (and a subject line where appropriate) using the voice defined in the bundled reference document. The output is the email itself, ready to copy and send.

## When to fire

Trigger on explicit phrases including: "draft an email", "write an email", "write a reply", "email to [name]", "reply to this", "email saying", "redraft this email", "compose an email", "email response", "draft a reply".

Do not fire on requests that mention email only incidentally (e.g. "summarise this email thread").

## Reference

Consult `business-email-voice.md` in this Skill's folder for the full voice reference. The document covers:

- Core voice principles and the three registers (casual, professional, formal)

- Sentence rhythm (long-short alternation)

- Vocabulary (words to use, words to avoid)

- Punctuation and formatting (British spelling, spaced hyphens not em dashes, no formulaic filler)

- Email structure by type (first outreach, reply, internal, unwelcome news, mistake)

- Opening and closing patterns

- Subject line guidance

- A failure-mode checklist

## Register

Default to the professional register for client emails and external recipients. Switch to the casual register for clearly internal emails or established client relationships where the user signals informality. Use the formal register only for legal documents or executive summaries. Ask if genuinely unsure.

## Output

Produce the email only. No preamble, no commentary, no "here is a draft" framing. Subject line on the first line if appropriate, then the body.

Before returning the output, silently run it against the failure-mode checklist in the reference document. Fix anything caught.
