What it does

Inbox Cleanup is an agent skill from HybridAIOne/hybridclaw. Tidy a crowded inbox by archiving newsletters, promotions and notifications in bulk, with a card the user approves and undo for 30 days. Use when the user wants to clean up, declutter or sort their inbox, get rid of newsletters or promotions, or has thousands of unread emails.

Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation, covering Email management and Newsletters. The repository describes itself as: Enterprise-ready self-hosted AI assistant runtime with sandboxed execution, secure credentials, approvals, and memory. The licence is MIT.

When your agent uses it

  • The user wants to clean up
  • Sort their inbox
  • Get rid of newsletters
  • Has thousands of unread emails

Example prompts

  • “/inbox-cleanup”

Workflow steps

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

  1. Call inbox_cleanup with action: plan. It looks at the newest inbox mail
  2. Say in one or two sentences what it found: how many emails it can archive and
  3. Call action: apply with the plan's preselected groups. The user sees a
  4. Report the numbers from the result: archived, skipped and why, not moved.
  5. When the user wants it back, call action: undo with the same plan_id.

What it can do on your machine

Read from SKILL.md and the folder at commit 8162701. 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

Inbox Cleanup loads about 702 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 393 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~702

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.

Inbox Clean-up

You can archive mail in bulk with inbox_cleanup. You cannot delete mail, and you never try to.

How

  1. Call inbox_cleanup with action: plan. It looks at the newest inbox mail by sender and mail headers and changes nothing.
  2. Say in one or two sentences what it found: how many emails it can archive and the two or three biggest senders. The card shows the rest, so don't list every group.
  3. Call action: apply with the plan's preselected groups. The user sees a card with the groups and decides there. Add a group the plan did not preselect, or leave one out, only when the user asks ("keep the Club mails").
  4. Report the numbers from the result: archived, skipped and why, not moved. Say once that undo works for 30 days. If the result has stopped_because, say what moved before it stopped.
  5. When the user wants it back, call action: undo with the same plan_id.

Rules

  • Mail moves only through inbox_cleanup. Never use the browser, a script or the shell to move, flag or delete mail, even if the user asks. That is how accounts get locked and mail gets lost.
  • If the user asks you to delete, empty the trash or remove mail for good, say that you only archive: archived mail is out of the inbox and never expires. If they still want it gone, they can delete the Archive folder's mail in their mail app themselves.
  • Never decide by words in a subject. "Offer", "invoice" or "deal" says nothing about who sent it. Trust the plan's groups.
  • Never say you read or checked emails you did not open. Say you sorted them "by sender and mail headers", because that is what the plan does.
  • Numbers come from tool results. If the plan says 2,140, don't round it.
  • The plan leaves alone mail from people the user writes to, starred mail, senders the user replied to, this week's mail and mail without bulk headers. Don't offer to include them.
  • A weekly tidy-up is a scheduled task that runs plan and tells the user what it found. It never archives without the user approving the card.
  • If plan or apply says the mailbox can't do it (no Archive folder, a server that can't report moves), say so in one sentence and stop. Don't try another way.
