Governed Support Ops Agent
Give AI agents real work, not unchecked power.
For US tech companies past Series A that need agents doing real work.
Most agent safety asks the model to behave. This decides what the agent is allowed to do: every action is checked against policy before it runs, outside the model, and logged after.
Four runs · the control that fired · the outcome
ASI10 Rogue Agents
Delete the account
- Policy
- 06-delete-account-never.cedar
- Call
- deleteAccount(ACC-5)
Hard forbid. 0 actions executed, nothing dispatched.
ASI01 Agent Goal Hijack
Indirect prompt injection
- Control
- agent-shield injection detector
- Call
- getPage(NTP-KB-5)
- Signatures
- instruction-override, control-bypass, false-authority, mass-action-directive
Quarantined before the planner. The agent still answers the real question.
Defense in depth: Cedar policy 02 separately blocks internal-tagged SOP pages at the access layer.
ASI04 Data Exfiltration
Unredacted PII read
- Policy
- 03-hubspot-pii-redacted.cedar
- Call
- getAccount(ACC-PII-1)
Default deny, then re-issued with redaction. Raw PII never reaches the model.
ASI09 Cost / Quota
Runaway loop, halted
- Control
- circuit breaker · $0.50 ceiling
- Call
- model call per iteration · $0.06 each
cost ceiling $0.50 reached (cumulative $0.54); 10th call never started
Each one writes to the audit log running across the top of every page: the action, the policy decision, and the outcome.
Two artifacts, one repo
A runnable Governed Support Ops Agent, and @sarthak/agent-shield: the governance layer (Cedar policies, audit log, kill-switch, MCP scope check, circuit breaker) extracted from this demo as a standalone reference.
