About this skill

“A set of resources to help me write all kinds of internal communications, using the formats that my company likes to use. Claude should use this skill whenever asked to write some sort of internal communications (status reports, leadership updates, 3P updates, company newsletters, FAQs, incident reports, project updates, etc.).”

— description from SKILL.md by anthropics

Internal Communications Writer is an official skill in anthropics/skills (180k stars). Its SKILL.md is about 378 tokens, with 5 other files in the folder, and copies of it appear in 37 other owners' repositories. Licence: Apache-2.0.

Workflow steps

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

  1. Identify the communication type from the request
  2. Load the appropriate guideline file from the examples/ directory
  3. Follow the specific instructions in that file for formatting, tone, and content gathering

What it can do on your machine

Read from SKILL.md and the folder at commit 683bc88. 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

Internal Communications Writer loads about 378 tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 133 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~378

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.
