Agent Governance Toolkit is a framework for controlling autonomous AI agents through policy enforcement, identity tracking, execution sandboxing, and reliability practices. Teams use it to decide which agent actions are allowed, identify agents in multi-agent systems, and keep records of decisions. The catalogue entries provide its instructions, commands, plugin, MCP server, and skill.
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 | $0.00019 | $0.00112 |
| Opus 5 | $0.00010 | $0.00056 |
| Sonnet 5 | $0.00004 | $0.00022 |
| Haiku 4.5 | $0.00002 | $0.00011 |
Grade A, and why
agt-check 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
If $ARGUMENTS is empty, tell the user to pass text to inspect.
Otherwise, call mcp__agt_governance__agt_policy_check_text exactly once with:
{"text":"$ARGUMENTS"}
Print the JSON result verbatim. Do not summarize or add commentary.
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.

agt-check is a command published in the GitHub repository microsoft/agent-governance-toolkit (6,199 stars, last pushed yesterday), licensed MIT. It adds 19 tokens to every session and 112 once invoked, about $0.0001 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.
