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 | $0.00044 | $0.00688 |
| Opus 5 | $0.00022 | $0.00344 |
| Sonnet 5 | $0.00009 | $0.00138 |
| Haiku 4.5 | $0.00004 | $0.00069 |
Grade A, and why
gmail-multi 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 2d 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.

Gmail Multi
Use this skill when working through the local gmail-multi MCP server. Treat the MCP server as the durable contract: it supports multi-account routing, Keychain token storage, safe modify actions, draft-first sending, and explicit confirmation for irreversible-feeling actions.
Core Rules
- Prefer
gmail_search_emailsfirst for mailbox analysis. It returns message metadata, snippets,nextPageToken, andresultSizeEstimate. - Shortlist from search results before reading bodies. Use
gmail_batch_read_messagesonly when snippets are insufficient. - Use
gmail_read_threadwhen prior context changes a summary, reply, recipient choice, or urgency classification. Usemax_messagesfor long threads. - Always state account, query/timeframe, result coverage, and whether bodies or full threads were read.
- Treat "needs reply" as an inference from content and thread state, not a guaranteed Gmail signal.
- Never use direct Gmail send. Create or update drafts, then stage send with
gmail_send_draft, then confirm withgmail_confirm_sendonly after explicit user approval. - Use
html_bodyplus a plain-textbodyfallback when a draft needs Gmail-safe rich rendering for code, JSON, compact tables, or other formatting. - For labels/archive/trash, prefer explicit message IDs. Query-based bulk labeling must go through preview and confirmation.

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

gmail-multi is a skill published in the GitHub repository arkaigrowth/gmail-mcp-server (0 stars, last pushed 1mo ago), licensed MIT.
