Inbox triage

Open your laptop. Your inbox is already sorted.

Free Claude skill from OpenKit. Reads your morning inbox and sorts it into urgent, watching and skip. Read-only, so nothing is sent.

  • Urgent
  • Watching
  • Skip
  1. 01

    Urgent

    Emails that genuinely need you today: a real ask, a deadline, or a reply to something you were chasing.

  2. 02

    Watching

    Threads where you are waiting on someone, or something brewing that is not urgent yet.

  3. 03

    Skip

    Newsletters, CC noise and automated alerts. Counted, never opened, so you see the volume without reading it.

How it works.

Three skills, working together. Two short setups teach it who you are and how you write, then the daily brief uses both.

run once it generates every day Build user context Build inbox voice user-context inbox-reply-drafter Inbox triage reads both, daily
  1. It learns you, you do not configure it

    Two one-time setups read your real email and ask a few questions, then build a personal profile and a drafter that writes the way you do. About fifteen minutes, once.

  2. Those two feed the daily one

    The profile says who matters to you and the drafter says how you write. Inbox triage reads both, so urgent means urgent for you, not for everyone.

  3. Then it runs every day

    Triage reads the window since you last looked, checks your sent folder so nothing already handled gets flagged, and sorts the rest. Ask any time, or let it run each morning.

  1. Download the skill

    One small file. No account, nothing to set up first, and nothing to unzip: you upload it as-is.

  2. Upload it to your AI, once

    Open your assistant's settings and add the file. That is the whole install.

    Settings → Capabilities → Skills → Upload skill. Pick the file and switch it on. On Claude Pro, Max, Team and Enterprise.

    Settings → Skills → New skill → Upload from your computer. On ChatGPT Business, Enterprise and Edu plans.

  3. Just ask for it

    Setup is done. Say this to get going, in plain English, with no command to memorise:

How to use it.

Once the skill is in your AI tool there is nothing to configure. You hand it the morning's emails and ask for the triage. It reads them and sorts them into urgent, watching and skip. When you want a reply, it hands off to your drafter, and nothing is ever sent on your behalf.

Common questions.

Is this AI inbox assistant safe to use?

Yes. The skill runs inside your own AI account and reads only the email content you paste in or connect. It sorts your inbox into urgent, watching and skip and sends nothing. Drafting a reply is a separate step you ask for.

Can it send emails for me, or will it auto-send replies?

No. It sorts your inbox into three piles and never sends or auto-sends anything. When you want a reply, it hands off to your drafter, and you review and send every email yourself.

Does OpenKit or Anthropic see my inbox?

No. The skill runs in your own AI account and only ever sees the email content you choose to paste or connect. OpenKit never receives your inbox, and you control how your conversations are handled in your AI assistant privacy settings.

Is the inbox triage skill free, and do I need a paid Claude plan?

It is free and MIT-licensed on GitHub, and you do not need a paid Claude plan. Skills work on the free plan as well as Pro, Max, Team and Enterprise; you just enable code execution in your Claude settings first.

How does the inbox triage skill sort my email?

It reads your morning inbox and sorts it into three piles: urgent for what needs you today, watching for what you are waiting on, and skip for the newsletters and noise it counts but never opens. It works with the Gmail or Outlook content you give it, and it is read-only.

How do I install the inbox triage skill without coding?

Download it from GitHub, then upload it in your AI's settings under Skills and switch it on. No coding needed, and it works the same in Claude and ChatGPT.

Need a skill the library doesn't cover?

We build bespoke skills, agents, and AI integrations for regulated industries. Same approach as the library: open-source where it can be, governed where it must be.
