Internal Comms Skill

Added 17 May 2026

Overview

Internal Comms is a reference skill that gives Claude a structured contract for drafting internal communications. It nudges the model toward outcome first, audience second, length-appropriate format third. Forks cleanly into team-specific voice variants.

Best for

Best for
Teams writing the same kind of internal post over and over

Use cases

  • Draft a weekly engineering update from a list of merged PRs
  • Turn a long Slack thread into a one-paragraph status post
  • Generate the 'we shipped' note for an internal launch
  • Standard format for incident retros

Notes

Why it matters

Internal writing is the highest-leverage repeated agent task most teams ignore. A skill that produces consistent shape across people pays for itself in a week.

How teams use it in production

Pair with a PM MCP that pulls last week’s shipped items. The agent has the source list. The skill enforces the shape. Result: a consistent weekly post nobody had to write.

What to watch

Companies that ship internal-comms skills early end up with a documented voice without an internal-comms hire.

Pros

  • Replaces inconsistent ad-hoc prompts with a real contract
  • Forks into team voice variants without losing structure
  • Composes with PM and CRM skills to pull real source data
  • Easy to wire into a slash command in any Claude harness

Cons

  • Voice tuning still takes a real first pass per org
  • Not a magic solve for 'we don't write enough internally'
  • Long-form strategy docs need a deeper system prompt
