Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00064 | $0.00684 |
| Opus 5.5 | $0.00026 | $0.00274 |
| Sonnet 5.5 | $0.00013 | $0.00137 |
| Haiku 4.5 | $0.00006 | $0.00068 |
Grade A, and why
inbox-cleanup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Inbox Clean-up
You can archive mail in bulk with inbox_cleanup. You cannot delete mail, and
you never try to.
How
- Call
inbox_cleanupwithaction: plan. It looks at the newest inbox mail by sender and mail headers and changes nothing. - 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.
- Call
action: applywith the plan'spreselectedgroups. 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"). - 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. - When the user wants it back, call
action: undowith the sameplan_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
planand tells the user what it found. It never archives without the user approving the card. - If
planorapplysays 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.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

inbox-cleanup is a skill published in the GitHub repository HybridAIOne/hybridclaw (159 stars, last pushed yesterday), licensed MIT. It adds 64 tokens to every session and 684 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings.
