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

m3-notify 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 5d 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

M3 Notify

When to Use

Use this skill when you start a session, at logical breakpoints, or when you want to poll the notification queue for messages, handoffs, task updates, or maintenance requests sent to you.

Instructions

Call m3:notifications_poll.

Render each notification as:

[<severity>] <created_at>  from <sender>:
  <message>
  ack: m3:notifications_ack with id=<id>

After listing, ask if the user wants to ack any (call notifications_ack) or ack-all (notifications_ack_all).

Empty inbox is the expected state — say "inbox is clear" rather than printing nothing.

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.
