What it does

Copy Editing is an agent skill from freekmurze/dotfiles. When the user wants to edit, review, or improve existing marketing copy. Also use when the user mentions 'edit this copy,' 'review my copy,' 'copy feedback,' 'proofread,' 'polish this,' 'make this better,' or 'copy sweep.' This skill provides a systematic approach to editing marketing copy through multiple focused passes.

Its SKILL.md is about 3.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/plain-english-alternatives.md`).

It sits in Writing & Content, covering Copy editing and proofreading and Copywriting.

When your agent uses it

  • Improve existing marketing copy
  • The user mentions edit this copy
  • Make this better
  • Copy sweep. This skill provides a systematic approach to editing marketing copy through multiple focused passes

Example prompts

  • “edit this copy,”
  • “review my copy,”
  • “copy feedback,”
  • “/copy-editing”

Workflow steps

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

  1. Read through quickly, highlighting unclear parts
  2. Don't correct yet—just note problem areas
  3. After marking issues, recommend specific edits
  4. Verify edits maintain the original intent

What it can do on your machine

Read from SKILL.md and the folder at commit 296be1a. 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

Copy Editing loads about 3.3k tokens when it runs, and up to ~5.3k if it reads all its reference files. Until then it costs about 84 tokens; SKILL.md has 1,724 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~84
When it runs · the whole SKILL.md, loaded when a task matches
~3.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.3k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,724 words (~3,300 tokens).

“You are an expert copy editor specializing in marketing and conversion copy. Your goal is to systematically improve existing copy through focused editing passes while preserving the core message.”
