Professional Email Rewriter

What it does

This prompt instructs the AI to transform a provided email draft into a polished, professional business email that preserves the original intent while improving clarity, structure, tone, and correctness. It produces a complete email with a suggested subject line, proper greeting and closing, and a brief summary of the key edits made to enhance professionalism and concision.

Inputs

textInputs

Pass each text input using --input <key>=<value> flags.

Models and options

This skill's modality is: text.

To discover which model values you can use (and which options keys/values are valid for each model), run:

betterprompt resources --models-only --json

Then filter the returned JSON array to entries where modality is "text".

How to run

Step 1: Collect inputs

First, run betterprompt resources --models-only --json and filter to modality: "text" to discover valid models and available options:

betterprompt resources --models-only --json

Use only the models and option values that appear in the filtered results.

Then collect all inputs from the human:

• Required text inputs:
  • tone
  • purpose
• Optional text inputs (use defaults if not provided by the human):
  • emailDraft (default: hey john, can you send me that report by tomorrow? i really need it for the meeting. thanks)
• Optional: model and options.
  • Present the human with the default model claude-sonnet-4 and its available options. Look up claude-sonnet-4 in the betterprompt resources output (filtered to modality "text") and show its availableOptions as: key: val1, val2 (default), val3 | key2: .... Mark a value (default) if it matches these defaults: {}.
  • If the human does not specify, defaults are used: model claude-sonnet-4, options {}. Other models from the resources call are also available.

If any required text input is missing, ask the human for what's missing. Do not assume or fabricate values.

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use professional-email-rewriter).

Command form:

betterprompt generate professional-email-rewriter \
  [--input <key>=<value>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• If the human does not mention a model, omit --model and BetterPrompt will use the default model: claude-sonnet-4.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {}.
• If the run times out, the response will include a runId you can use to fetch the result later.

Example (using defaults shown above):

betterprompt generate professional-email-rewriter \
  --input tone=formal \
  --input purpose=apology \
  --input 'emailDraft=hey john, can you send me that report by tomorrow? i really need it for the meeting. thanks' \
  --model claude-sonnet-4 \
  --options '{}'
