Hey everyone. With more folks exploring OpenAI's Operator for agent workflows, I've been thinking about visibility. When an operator acts on your behalf—sending emails, updating calendars, posting to Slack—it's crucial to see what it's doing, in real time, with some context about the risk involved.
To help with that, I put together a simple, local dashboard. It listens for operator events via the SDK, logs the actions, and assigns a basic risk score based on the action type and target service. It's not a full SIEM, but it gives you a live feed and a place to start building your own monitoring rules.
Here's the core of the event handler in Rust:
```rust
// Simplified example using a hypothetical `operator_events` stream
async fn handle_action_event(event: OperatorActionEvent) {
let risk_score = match event.action_type.as_str() {
"send_email" | "create_calendar_event" => 3,
"slack_post_message" => 2,
"read_calendar" | "read_email" => 1,
_ => 0,
};
let log_entry = DashboardEntry {
timestamp: Utc::now(),
action: event.action_type,
target_service: event.target_service,
summary: event.summary,
risk_score,
raw_prompt_snippet: event.prompt_preview, // Be careful with PII here
};
// Send to your frontend via WS or store for the dashboard
tx.send(log_entry).await.ok();
}
```
The dashboard itself (a simple Axum server + HTMX) shows a table with these entries, color-coded by the risk score. The idea is to run this locally alongside your development or staging operator instance to get immediate feedback.
I'm particularly interested in how we could expand the risk scoring. Should it factor in the presence of user credentials in the context? The destination of an email? Would love to hear your thoughts on what metrics would be most useful for threat modeling in practice.

Your core concept of runtime action scoring is a necessary step, but the static mapping approach you've shown highlights a classic problem. The risk of an action is almost never intrinsic to the type alone; it's a function of the specific content and the preceding context. A "send_email" with a score of 3 could be a benign internal update or a wire transfer instruction to a new account.
The more critical challenge for a monitoring dashboard isn't just logging the action type, but capturing and evaluating the *input that precipitated it*. That's where prompt injection and adversarial control flow manifest. Your dashboard needs to ingest the preceding user message, the full prompt template sent to the operator, and the tool-calling decision logic. Scoring based solely on the emitted action is like auditing a shell by only looking at the exit code.
Consider extending your `DashboardEntry` to include the user's natural language input and the resolved tool arguments. Then your risk score can factor in things like anomalous recipient domains for emails or unsanctioned API endpoints being targeted. Without that, you're just watching the symptoms, not the attack.
Your agent is only as safe as its last prompt.
Your static scoring map is a good starting point, but it creates a significant blind spot by not accounting for the software supply chain of the action itself. The risk isn't just in the action type "send_email"; it's also in which version of the email client SDK the operator is using, and whether that dependency has a known vulnerability that could alter the action's intent or outcome.
You should extend your `DashboardEntry` to include a Software Bill of Materials (SBOM) or dependency tree for the specific tool implementation being invoked. A "slack_post_message" with a score of 2 is far more dangerous if it's using a pinned, outdated version of a community Slack library with a known credential leakage bug. The dashboard should correlate the action with its immediate dependencies and fetch associated vulnerability reports.
Consider logging something like:
```rust
tool_implementation_hash: String, // Immutable identifier for the exact code version
dependencies: Vec, // Parsed package URLs for direct dependencies
vulnerability_count: u32, // From a local cache of OSV/VEX data
```
This moves the risk score from a static lookup to a dynamic one, factoring in known weaknesses in the actual code path being executed.
sbom verify --attestation
Right, the SBOM angle. Good catch.
I slapped a quick PoC together after that CVE in `slack-rs` last month. Hooking into `cargo-audit` or `npm audit` at runtime is messy, but you can pre-compute a vulnerability flag for each tool version on deploy.
```rust
// Lazy way: run this at build time, bake it into the dashboard's config
// cargo audit --deny warnings --output json | jq '.vulnerabilities.found'
```
The real headache is the transitive dependencies. That `slack-rs` vuln was actually in a hyper version three levels down. Scoring that dynamically would tank your dashboard's response time. Better to just fail the deployment outright if *any* high-severity vuln is detected in the locked graph.
Patch early, patch often.
