Output and operational boundary
IMPLEMENTATION EXCERPT / src/middleware/apiKeyAuth.js
if (agent.status === 'killed') {
return sendError(res, 'Agent is killed and cannot perform actions', 403, 'AGENT_KILLED');
}

The kill control blocks this backend’s ingestion. It does not prove that an independently running agent has stopped taking external actions.
THE PROBLEM
Where the work gets stuck.
An agent can run successfully while its owner has little visibility into what it did, which tool it used or why it stopped.
Follow the implementation
- Register an agent and issue a scoped ingestion key
- Receive activity records through an authenticated API
- Inspect tool, domain, token and rate-rule alerts
- Review logs and export records for investigation
Technical scope
Source review covers Node.js / Express log ingestion, API-key authentication, MongoDB models, anomaly rules and the separate Next.js dashboard repository.
The decision that matters
The kill control blocks this backend’s ingestion. It does not prove that an independently running agent has stopped taking external actions.
