What it does

Eos Style is an agent skill from neurofoo/agent-skills. Strunk & White style review using the 21 reminders from "Elements of Style" Chapter V. Use when editing prose, reviewing drafts, or improving writing clarity and tone.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Agent Skills for Claude Code and OpenCode. The licence is MIT.

When your agent uses it

  • Reviewing drafts
  • Improving writing clarity and tone

Example prompts

  • “Elements of Style”
  • “/eos-style”

Workflow steps

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

  1. Place yourself in the background — Write to serve the reader, not to show off. Style emerges from content, not from the writer's ego.
  2. Write naturally — Don't consciously imitate others or force an affected style. Write as you would speak to an intelligent friend.
  3. Work from suitable design — Plan your piece. Know your scope and structure before writing extensively.
  4. Write with nouns and verbs — These give writing strength. Adjectives and adverbs are not your principal weapons.
  5. Revise and rewrite — Good writing is rewriting. Don't expect first drafts to be final.
  6. Don't overwrite — Avoid ornate, flowery prose. Rich prose is hard to digest.
  7. Don't overstate — Avoid superlatives and exaggeration. A single overstatement can undermine your credibility.
  8. Avoid qualifiers — Words like "very," "rather," "quite," "pretty," and "little" weaken prose.
  9. Don't affect breeziness — Forced casualness and flip remarks suggest the writer values cleverness over substance.
  10. Use orthodox spelling — Follow standard conventions unless you have good reason not to.
  11. Don't explain too much — Trust the reader. Avoid excessive adverbs after "said" and over-explanatory dialogue tags.
  12. Don't construct awkward adverbs — Avoid forcing "-ly" onto words that don't take it naturally.

What it can do on your machine

Read from SKILL.md and the folder at commit 0e7ac2a. 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

Eos Style loads about 1.3k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 660 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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.

Principle Reference

  1. Place yourself in the background — Write to serve the reader, not to show off. Style emerges from content, not from the writer's ego.

  2. Write naturally — Don't consciously imitate others or force an affected style. Write as you would speak to an intelligent friend.

  3. Work from suitable design — Plan your piece. Know your scope and structure before writing extensively.

  4. Write with nouns and verbs — These give writing strength. Adjectives and adverbs are not your principal weapons.

  5. Revise and rewrite — Good writing is rewriting. Don't expect first drafts to be final.

  6. Don't overwrite — Avoid ornate, flowery prose. Rich prose is hard to digest.

  7. Don't overstate — Avoid superlatives and exaggeration. A single overstatement can undermine your credibility.

  8. Avoid qualifiers — Words like "very," "rather," "quite," "pretty," and "little" weaken prose.

  9. Don't affect breeziness — Forced casualness and flip remarks suggest the writer values cleverness over substance.

  10. Use orthodox spelling — Follow standard conventions unless you have good reason not to.

  11. Don't explain too much — Trust the reader. Avoid excessive adverbs after "said" and over-explanatory dialogue tags.

  12. Don't construct awkward adverbs — Avoid forcing "-ly" onto words that don't take it naturally.

  13. Make sure speakers are clear — In dialogue, readers must always know who is speaking.

  14. Avoid fancy words — Prefer the plain word to the fancy one. "Home" not "domicile."

  15. Use dialect sparingly — The best dialect writers use minimal deviation from standard language.

  16. Be clear — Clarity is the foundation. Muddiness is not depth; obscurity is not profundity.

  17. Don't inject opinion — Keep personal opinions out unless they serve the work. They mark the egoist.

  18. Use figures of speech sparingly — Metaphors and similes need space. Constant comparison exhausts the reader.

  19. Don't sacrifice clarity for shortcuts — Strong, precise words are better than clever abbreviations.

  20. Avoid foreign languages — Write in English. Foreign phrases can seem pretentious.

  21. Prefer standard to offbeat — Choose established words over trendy or invented ones.

Guidelines

  • Focus on patterns, not isolated instances
  • Some rules can be broken intentionally for effect—note when this seems intentional
  • "Needs Work" means a pattern of violations, not a single instance
  • Technical or specialized writing may legitimately use jargon
  • Creative writing may intentionally break rules for voice
