Works with · DiaCroma for Agents
Your agents, your tools, your rules, your guards stay.
D4A adds the limits and the proof.

Bring your own rules
Your agents’ instructions already hold limits. Your platform team already wrote the rules. D4A applies them before every action of every agent, without rewriting a single agent.
Your agents’ instructions already hold limits. D4A reads them in Foundry and proposes each one with the sentence it came from. A person signs. In D4A today.
Open Policy Agent: the open-source engine many platform teams already use to decide what is allowed. In D4A today.
An open-source language for permissions, created at AWS. Same contract in D4A, to be measured with a real Cedar engine.†
Microsoft’s policy toolkit for agents. Joins your rules where it answers in milliseconds.†
You connect your rules once, in your own installation, never through our panel.
You choose how hard your rules stop.
The refund agent
Signed to refund up to $300. Your company rule says $150. It tries $200.
Our sample organization: a company rule stopping a refund agent in production, measured on 30 Oct 2026.
The disagreement report†
On every action, D4A records what your OPA or Cedar policies decided and what the agent’s rules decided. Four boxes, from your installation, last thirty days.
Illustrative numbers, sample organization, in Enforcing.
Who reviews the week
The Watch reviews what every agent did, not one action at a time. When something looks off, it opens a case for a person.†
The case reaches your people in Microsoft Teams†, or by email.
The Watch never stops an action and never changes a limit. Microsoft marks Task Adherence as preview.
