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-govern-manage 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 13d 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.

Microsoft 365 Governance & Management

Uncontrolled collaboration sprawl - orphaned Teams, broad sharing, stale guests, overshared sites - increases data risk and is the #1 blocker to a safe Microsoft 365 Copilot rollout. This skill governs the Microsoft 365 collaboration estate without strangling productivity.

When to use

Use this skill when the user is preparing for Copilot, dealing with sprawl from years of open-by-default Teams creation, or building a long-term collaboration governance programme.

Do not use this skill for:

  • DLP policy design (use purview-dlp-policy)
  • Sensitivity label classification (use purview-data-classification)
  • Copilot-specific oversharing remediation (use purview-copilot-oversharing)
  • Entra access reviews for app/role access (use entra-id-governance)

Pick the right control for the symptom

Symptom Control Required licence
Anyone can create Teams; hundreds of orphaned groups M365 group creation restriction + naming + expiration policy Entra ID P1 (for expiration)
Guests added years ago still in groups Entra access reviews for guests Entra ID P2
Sites shared with "Everyone except external users" by default SharePoint default sharing link = People in org M365 E3+
Site contains sensitive data + open sharing Restricted Access Control (RAC) + sensitivity label SAM (E5 + SAM add-on)
Cannot see which sites overshare sensitive data SAM Data Access Governance reports SAM (E5 + SAM add-on)
Inactive sites cluttering tenant SAM inactive-site policy + site lifecycle SAM (E5 + SAM add-on)
Teams chat retention going forever Retention policy (forward-only) M365 E3 +
Need to block Copilot from indexing a site Restricted Content Discovery (RCD) SAM (E5 + SAM add-on)

Rule of thumb: governance for sprawl follows discover → tighten defaults → clean up existing → maintain. Skip discovery and you tighten the wrong controls.

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.
