At a glance

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

  • Works in 5 steps: Best -- default, works almost everywhere → Thanks -- when you're asking for… → Best regards -- one step more formal,… → …
  • The user is writing for an American audience: emails
  • SKILL.md covers Spelling (EN-US), Tone Ladder, Sign-off Ranking and Avoid List, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Us Business English is an agent skill from jezweb/claude-skills. American business English writing style for professional communications — direct, action-oriented, EN-US spelling (color, organize, center). Use whenever the user is writing for an American audience: emails, chat messages, proposals, client communications, blog posts, web copy, or any business writing. Apply to drafting, editing, and tone-checking professional text.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Proposals and quotes, Blog and article writing and Brand voice and tone. The repository describes itself as: Skills for Claude Code CLI such as full stack dev Cloudflare, React, Tailwind v4, and AI integrations. The licence is MIT.

When your agent uses it

  • The user is writing for an American audience: emails
  • Client communications
  • Any business writing

Example prompts

  • “/us-business-english”

Workflow steps

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

  1. Best -- default, works almost everywhere
  2. Thanks -- when you're asking for something or appreciating effort
  3. Best regards -- one step more formal, good for proposals
  4. Regards -- neutral, slightly cooler
  5. Talk soon -- casual, signals ongoing relationship

What it can do on your machine

Read from SKILL.md and the folder at commit 1260fa7. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

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

  • Credentials

    Names no API keys, tokens, secrets or passwords.

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

Context cost

Us Business English loads about 2.1k tokens when it runs. Until then it costs about 97 tokens; SKILL.md has 1,089 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~97
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

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.

description
American business English writing style for professional communications — direct, action-oriented, EN-US spelling (color, organize, center). Use whenever the user is writing for an American audience: emails, chat messages, proposals, client communications, blog posts, web copy, or any business writing. 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)

PatternAmericanNot
-orcolor, favor, honor, behaviorcolour, favour
-izeorganize, realize, specialize, recognizeorganise, realise
-ercenter, fiber, meter, theatercentre, fibre
-enselicense (noun and verb), defense, offenselicence (noun), defence
Single Ltraveling, canceling, modelingtravelling, cancelling
-ogcatalog, dialog, analogcatalogue, dialogue
-mentjudgment, acknowledgmentjudgement, 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.

ContextFormalityGreetingSign-off
Slack/Teams (internal)Casual"Hey" / first nameNone needed
Email to existing clientProfessional friendly"Hi [Name]""Best" / "Thanks"
Email to new clientProfessional"Hi [Name]""Best" / "Thanks"
Proposal or quoteProfessional"Hi [Name]""Best regards" / "Best"
Follow-up after meetingProfessional friendly"Hi [Name]""Thanks" / "Talk soon"
Cold outreachWarm professional"Hi [Name]""Best" / "Thanks"
Formal letter or legalFormal"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
  2. Thanks -- when you're asking for something or appreciating effort
  3. Best regards -- one step more formal, good for proposals
  4. Regards -- neutral, slightly cooler
  5. Talk soon -- casual, signals ongoing relationship

Avoid: "Cheers" (sounds British/Australian to American ears), "Kind regards" (slightly stiff), "Warm regards" (overdone), "Respectfully" (government/military tone).

Avoid List

Corporate Buzzwords

Replace these reflexively:

Instead ofWrite
"synergy" / "synergize""working together" / "combined effort"
"leverage" (verb)"use" / "take advantage of"
"circle back""follow up" / "come back to this"
"touch base""check in" / "connect"
"loop in""include" / "bring in"
"bandwidth" (for time)"time" / "capacity"
"actionable insights""useful information" / "what we found"
"move the needle""make a difference" / "improve"
"deep dive""closer look" / "detailed review"
"pivot""change direction" / "adjust"
"align on""agree on" / "get on the same page"
"unpack" (an idea)"look at" / "go through"
"cadence""schedule" / "frequency"
"deliverables""what we'll provide" / "the work"
Foreign-isms and Overcorrections

Avoid in written professional comms:

  • "Whilst", "amongst" -- use "while", "among"
  • "Shall" -- use "will" or "should"
  • "Keen" -- use "interested" or "excited about"
  • "Brilliant" / "lovely" -- sounds British, use "great" / "sounds good"
  • "Dude", "awesome", "totally" in formal emails -- fine on Slack, not in proposals
  • Forced casualness -- "Hey buddy!" to a new client is too much

Writing Principles

  1. Lead with the point. First sentence answers the question or states the purpose. Context comes after, not before.

  2. Short paragraphs. Two to three sentences max. One idea per paragraph. White space is your friend.

  3. Natural contractions. "We've", "I'll", "that's", "won't" -- reads human. Ease off slightly in proposals, but emails should sound like a person wrote them.

  4. Active voice. "We'll send the report Monday" not "The report will be sent on Monday."

  5. Specific over vague. "I'll have this to you by Thursday" not "I'll get back to you soon."

  6. One ask per email. Multiple requests? Number them. Don't bury the second ask in paragraph four.

  7. Match their energy. Short email from client? Short reply. Detailed brief? Detailed response. Don't write five paragraphs when two lines will do.

Status update to existing client

Too corporate:

Dear Mr. Thompson, I am writing to provide you with a comprehensive update regarding the current status of your website redesign project. Please find below a summary of the deliverables completed to date and the anticipated timeline for remaining action items moving forward.

Right tone:

Hi David,

Quick update on the website -- we've finished the homepage and the three main service pages. Everything's looking solid.

Next up is the contact form and booking system, which we'll have ready by end of next week. I'll send over a preview link once it's live on the staging site.

Best, [Your name]

Delivering a quote

Too stiff:

Dear Client, Please find attached our formal quotation for the proposed scope of work as discussed. We trust this meets your requirements and look forward to your favorable response at your earliest convenience.

Right tone:

Hi Sarah,

Thanks for the call yesterday -- good to get a clear picture of what you need.

I've put together a quote based on what we discussed. The short version: $4,500 for the full site, including the booking system. That covers design, development, and getting it live on your domain.

Happy to hop on a call if you have any questions.

Best, [Your name]

Saying no to a request

Too blunt:

We can't do that.

Too soft:

While we certainly appreciate your suggestion and would love to explore this further, unfortunately at this current juncture it may not be feasible for us to accommodate this particular request given our current bandwidth constraints.

Right tone:

Hi Mark,

Thanks for thinking of us for this. Unfortunately it's not something we can take on right now -- we're at capacity through March.

If timing works, we'd be happy to look at it in April. Otherwise, I can recommend a couple of people who might be able to help sooner.

Best, [Your name]

Context Rules

Corporate clients: Match their formality up one notch but stay clear and human. "Best regards" instead of "Best", but still "Hi [Name]" not "Dear Mr. Smith". Never mirror their jargon back -- if they say "synergize", you say "work together".

Delivering bad news: Be direct but kind. State the issue, explain why briefly, offer the path forward. No filler, no excessive apologies. One "sorry" is enough -- two is apologetic, three is groveling.

Quoting prices: Direct and confident. "The cost for this is $X" not "We would like to propose a fee of $X for your consideration." Include what's covered. No hedging. Use dollar amounts without "USD" unless international context requires it.

Saying no: Respectful and brief. Give the reason (one sentence), offer an alternative if possible. Don't over-explain or apologize excessively.

Following up: Casual but purposeful. "Just checking in on this" is fine. "I trust this email finds you well" is not. "Wanted to bump this to the top of your inbox" works too.
