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 | $0.00241 | $0.02303 |
| Opus 5 | $0.00120 | $0.01151 |
| Sonnet 5 | $0.00048 | $0.00461 |
| Haiku 4.5 | $0.00024 | $0.00230 |
Grade A, and why
agent-identity-governance 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.
How it starts
The opening of the file, as written. The whole thing — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Agent & Non-Human Identity Governance
AI agents — Microsoft 365 Copilot Studio agents, Microsoft Foundry agents, custom-built ones, plus traditional service principals and managed identities — are now the fastest-growing identity population in most tenants. They authenticate, hold permissions, act on behalf of users (or themselves), and are usually under-governed.
This skill is the lifecycle governance layer for those identities: ownership, scoping, credential hygiene, reviews, decommissioning, and incident response.
When to use
Establishing or maturing governance for the agent / NHI population — Copilot Studio agents, Foundry agents, custom LLM agents, and the service principals that back them.
Do not use this skill for workload identity federation patterns alone
(entra-workload-identity), human identity governance (entra-id-governance), or
generic agent build guidance.
Agent identity inventory — know what you're governing
| Class | Identity model | Surface |
|---|---|---|
| Copilot Studio agent (M365) | Tenant-scoped agent identity + per-user delegated permissions | M365 admin center / Copilot Studio |
| Microsoft Foundry agent | Service principal + managed identity + per-user OBO | Azure portal / Foundry |
| Custom AI agent (your code) | App registration + workload identity federation / managed identity | Entra admin center |
| Plugin / connector | Service principal + delegated/app Graph permissions | Entra admin center |
| Legacy automation service principal | App registration, often with secret | Entra admin center |
Approach
- Inventory and tag. Pull every app registration, service principal, and Copilot
Studio / Foundry agent. Tag each with:
- Owner (person + group).
- Sponsor / business owner.
- Purpose (one sentence).
- Data scope (which tenants/sites/mailboxes/resources).
- Lifecycle stage (pilot / production / sunset).
- Criticality (tier 0 / 1 / 2). Orphaned identities → freeze them; require owner re-claim.
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.

agent-identity-governance is a skill published in the GitHub repository vinayaklatthe/microsoft-security-skills (173 stars, last pushed 2mo ago), licensed MIT. It adds 241 tokens to every session and 2,303 once invoked, about $0.0012 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.
