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
