A free, open-source Claude skill from OpenKit. Sorts your morning inbox into four piles and drafts replies in your voice. Writes nothing back to your email.

What it does

Every morning, give Claude your inbox. The skill returns one short brief:

  • Reply today — emails that need you, with drafts ready.
  • Chasing — threads you are waiting on, with suggested follow-ups.
  • Skip — newsletters, CC noise, automated alerts. Counted, never opened.
  • Hand off — things your team should handle, with suggested handoff messages.

No emails are sent. No threads are modified. The brief is a report.

Setup

  1. Install: npx @openkit/skills install inbox-triage
  2. (Optional, recommended) Run build-user-context once. The triage reads your generated context at runtime.
  3. (Optional) Run build-inbox-voice once. Drafts will sound like you.

How to use

Paste or forward your morning inbox to Claude and ask:

“Run inbox triage on these.”

Claude returns the four-pile brief. Review the drafts in the Reply today pile, copy what you want, and paste into your real email client.

Privacy

  • The skill runs on your Claude account.
  • OpenKit never sees your inbox.
  • Drafts live in Claude’s response. Nothing is auto-sent.

FAQ

Common questions.

Does it have access to my inbox?

Only what you paste or connect via your own Claude account. OpenKit never sees it.

Can I use it without Claude Code CLI?

Yes. Drop the skill folder into Claude Desktop's skills directory and ask Claude to triage your inbox.

What if my voice changes over time?

Run build-inbox-voice again. It rebuilds the drafter from your most recent sent folder.

Is it really free?

Yes. MIT-licensed, hosted on GitHub. The bet is that you will want help with the next thing.
