Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

m365-mail 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 11d 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.

What it actually says

M365 Mail

Use this skill to work with Outlook mail messages.

Workflow

  1. Start with action=list or a constrained action=search via the m365_mail tool.
  2. Open specific messages by ID with action=read.
  3. Summarize sender, subject, date, and action items.
  4. For drafts and replies, use action=draft, action=reply, or action=forward — these create drafts only, never send directly.
  5. Attach local files with attachments='path1;path2' (max 3MB per file, semicolon-separated).

Guardrails

  • Avoid dumping full message bodies unless the user requests it.
  • Keep results scoped with top.
  • For batch operations (batch_delete, batch_move, batch_archive, batch_flag), always use dryRun=true first.
  • Confirm with the user before destructive actions.
Changes

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.
