## What it does

The skill kicks in when you draft an email, a chat message, a proposal or web copy for an American audience. The agent edits the draft, checks the tone and fixes spelling: `color`, `organize`, `center`, `license` as both noun and verb. Dates follow Month Day, Year.

Inside there is a spelling table with the British variants to replace, a tone ladder from Slack messages up to legal letters, and a list of corporate buzzwords with plain swaps. "Leverage" becomes "use", "circle back" becomes "follow up". Sign-offs get their own ranking: `Best` as the default, `Thanks` when you are asking for something, and `Cheers` is advised against.

One thing to know: the skill does not translate. It edits English you already wrote. If your draft is in another language, translate it first or the agent has nothing to clean up. No environment requirements — it is a single `SKILL.md` file of instructions.

description: "American business English writing style for professional communications — direct, action-oriented, EN-US spelling (color, organize, center).

Apply to drafting, editing, and tone-checking professional text."

# US Business English

Professional and direct. Confident without being pushy. Friendly without being sloppy. Write like a competent American professional who gets things done -- not like a Silicon Valley bro, not like a Wall Street memo, and not like a corporate buzzword machine.

## Spelling (EN-US)

| Pattern | American | Not |
|---------|----------|-----|
| -or | color, favor, honor, behavior | colour, favour |
| -ize | organize, realize, specialize, recognize | organise, realise |
| -er | center, fiber, meter, theater | centre, fibre |
| -ense | license (noun and verb), defense, offense | licence (noun), defence |
| Single L | traveling, canceling, modeling | travelling, cancelling |
| -og | catalog, dialog, analog | catalogue, dialogue |
| -ment | judgment, acknowledgment | judgement, acknowledgement |

**Noun/verb note:** Unlike British/Australian English, American English uses "license" and "practice" for both noun and verb forms. No split needed.

**Common traps:** inquiry (standard, not enquiry), curb (road edge), tire (wheel), program (all contexts), check (not cheque), gray (not grey).

**Date format:** Month Day, Year -- January 15, 2026. Use this in all written communications unless matching a specific system format.

## Tone Ladder

Match formality to context. Default to "professional friendly" -- clear and personable.

| Context | Formality | Greeting | Sign-off |
|---------|-----------|----------|----------|
| Slack/Teams (internal) | Casual | "Hey" / first name | None needed |
| Email to existing client | Professional friendly | "Hi [Name]" | "Best" / "Thanks" |
| Email to new client | Professional | "Hi [Name]" | "Best" / "Thanks" |
| Proposal or quote | Professional | "Hi [Name]" | "Best regards" / "Best" |
| Follow-up after meeting | Professional friendly | "Hi [Name]" | "Thanks" / "Talk soon" |
| Cold outreach | Warm professional | "Hi [Name]" | "Best" / "Thanks" |
| Formal letter or legal | Formal | "Dear [Name]" | "Sincerely" |

**Never use:** "Dear Sir/Madam" (unless truly unknown recipient in legal context), "Warmest regards", "Respectfully yours" (reserve for military/government), "Cheers" (reads as affected British).

## Sign-off Ranking

From most to least common in US SME context:

1. **Best** -- default, works almost everywhere
```
