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 | $0.00175 | $0.01776 |
| Opus 5 | $0.00088 | $0.00888 |
| Sonnet 5 | $0.00035 | $0.00355 |
| Haiku 4.5 | $0.00017 | $0.00178 |
Grade A, and why
microsoft-agent-365 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 12d 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.

Managing AI Agents with Microsoft Agent 365
Microsoft Agent 365 is the control plane for agents - it extends the infrastructure you use to manage people (identity, access, data protection, threat defense) to AI agents, regardless of where they originate (Microsoft, Copilot Studio, partner/third-party including agents built on Anthropic Claude, OpenAI, or Google Gemini, or custom-built). It organises the work into three pillars: observe, govern, and secure. Generally available for Commercial since 1 May 2026, licensed per user, with Microsoft E5 as the recommended prerequisite.
When to use
Standing up enterprise-wide management for a growing fleet of AI agents - when you need a single inventory, consistent lifecycle and access controls, and unified security across agents built on different platforms. Use it as the orchestration layer that ties together Entra, Purview, and Defender for agents.
Do not use this skill for Purview data-security controls on a single agent in isolation (use
purview-agent-365-security), or to remediate Microsoft 365 Copilot oversharing of end-user
content (use purview-copilot-oversharing / m365-oversharing).
Pick the right pillar for the problem
| Goal | Pillar | Primary surface |
|---|---|---|
| Know how many agents exist, who owns them, how they're used | Observe | Agent registry + Agent Map in Microsoft 365 admin center |
| Onboard, approve, review, and retire agents with policy | Govern | Agent management in M365 admin center + Microsoft Purview |
| Give each agent a managed identity and risk-based access | Secure | Microsoft Entra Agent ID + Conditional Access |
| Stop agents leaking or over-accessing sensitive data | Secure | Microsoft Purview (DSPM for AI, DLP, sensitivity labels, IRM) |
| Detect malicious or unsafe agent behaviour at runtime | Secure | Microsoft Defender for Cloud Apps (real-time agent protection) |
Rule of thumb: treat every agent as a first-class, governed identity - not a feature of an app. The more autonomous the agent, the more it must be managed like a privileged account.
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.

microsoft-agent-365 is a skill published in the GitHub repository vinayaklatthe/microsoft-security-skills (173 stars, last pushed 2mo ago), licensed MIT. It adds 175 tokens to every session and 1,776 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
