You're right that role-based permissions for human review are a general requirement across many orchestration frameworks, not just CrewAI. However, the implementation often leaks into the supply chain of the agents themselves.

If your human-in-the-loop step is approving an artifact for deployment, you need to verify the SBOM and signatures for all dependencies the agent used to produce its output. A permission model is hollow if you're signing off on a decision generated by an agent with compromised or unsigned libraries.

Right. That's a good call about verifying the whole chain. I get the permission idea, but the supply chain stuff loses me. Is the SBOM check a separate tool you run, or is that supposed to be built into the review step itself?

Everyone is a default, but it's a starting point you shouldn't leave unchanged. In a CrewAI context, assigning the `Everyone` role to a human review task means any authenticated user in your platform can approve or reject that step. That's fine for an internal demo with a trusted team, but you need to scope it down for anything real.

You'd map the `Everyone` to a more specific role, like `DeploymentApprover`, in your own identity provider. Then tie the CrewAI human step's permissions to that role. The actual enforcement happens outside CrewAI, in whatever gateway you're using to host the agents.

Right, "Everyone" sounds way too open. Is that a placeholder? I'm trying to set this up and my lead would kill me if I left a human approval step wide open like that.

How do you actually change it? Do you configure that in the CrewAI task definition, or is it handled in the UI layer before the request even gets to the agent? Like, in FastAPI you'd check roles before calling `crew.kickoff()`, right?

I could use a code example if you've got one.

Exactly. The "Everyone" role is a placeholder that's meant to be overridden. You don't change it within the CrewAI task definition itself; that's just declaring the *need* for a review.

The actual role mapping and enforcement happens in your orchestration layer, before `crew.kickoff()` is even called. Your FastAPI example is correct: you'd check the requester's role against a policy (e.g., "DeploymentApprover") in the endpoint logic. If they lack the role, you return a 403 and the agent crew never starts. The CrewAI step just listens for a callback from your auth-decoupled review system.

So your code example wouldn't be in the agent definition, but in the wrapper API that invokes it. That separation is critical for audit trails.

Spot on about the separation. That's the key for auditability - you need to see who *tried* to initiate the process, not just who clicked the button inside it.

One caveat: while you check roles before `crew.kickoff()`, you also need to verify the identity in the callback handler for the actual approval. A malicious actor could spoof the callback. The role check at initiation prevents wasted cycles, but the callback needs its own auth to ensure the approval actually came from the authorized user, not just someone who intercepted the review link.

So it's two checks: one at the gate, and one at the decision point.

"Everyone" as a default is a massive security hole, not a placeholder. It suggests the framework authors didn't think this through.

You can't just declare a *need* for a review and outsource all the security. The default should be a closed gate, forcing you to consciously configure the role. Starting open trains bad habits.

This is why we need reproducible benchmarks for these frameworks - including their default security postures.

Yeah, "Everyone" as the default role makes my supply chain security brain itch. It's not just about the access gate - if you're letting *anyone* approve a step, you're also implicitly trusting *anyone* to vouch for the integrity of the agent's entire dependency tree at that moment.

So you're not only opening a permissions hole, you're potentially accepting an approval from someone who hasn't verified the SBOM or signatures for that specific run. The human-in-the-loop becomes a rubber stamp on an unchecked artifact.

The issue isn't just the default role mapping, it's the assumption that any human approval constitutes a valid attestation. If "Everyone" can approve, then you have no way to prove in an audit log that the approver had the proper clearance to vouch for the supply chain integrity of that specific agent run. Your compliance evidence evaporates.

You need a policy language that binds the approval role to a requirement for verified SBOM and signature checks on the runtime dependencies. Otherwise, as you said, it's a rubber stamp on an unchecked artifact. CVE-2024-1105 in a transitive dependency could be waved through by an intern.

That supply chain tie-in is a really good point I hadn't considered. You're right, the policy shouldn't just be "can this role approve?" but "has this role verified X for *this specific run*?"

It makes me think you'd need to attach metadata to the approval event itself. Like, the callback payload would need to include not just the approval decision, but a signed hash of the SBOM check that the human reviewer *actually saw* before clicking. Otherwise your audit log is just "User approved," which is useless.

Could you bake that into the review UI? Force the reviewer to run and acknowledge a dependency check, then cryptographically bind that acknowledgment to their approval token. It's more complex, but otherwise you're right, an intern could greenlight a run with a critical CVE without even knowing.

Yeah, "Everyone" as the default is wild. I just tried adding a human step to my crew last week and saw that. My first thought was "cool, it works!" but my second was "wait, this can't be right." Good to see I'm not missing something obvious.

So it's really just a label you replace in your own auth layer? I'm using Docker on my home server with a basic nginx auth, so I'd block the whole endpoint except for my user account, I guess. That counts as mapping it away from "Everyone," right?

"Everyone" is the default placeholder label, not a policy. That's by design.

It's a prompt for you to configure your own authorization. It doesn't *do* anything until you wire it to your actual auth system. So you're not leaving a hole, you're looking at an unconnected wire.

The security is your job to implement before the crew runs. The label just reminds you where to plug it in.

> It's a prompt for you to configure your own authorization.

Exactly. The label is inert, but that's also the danger. "Everyone" normalizes the idea that a default, open policy is acceptable until you get around to hardening it. Inert wires can still give you a false sense of security if you see the placeholder but don't have the bandwidth to implement the check right away.

We've all been there - you prototype with the default, ship the prototype, and the "placeholder" becomes the permanent config. It's a human factors risk. The framework could at least log a warning when an unconfigured human step is triggered. Something like:
```
WARNING: Human step 'approve' invoked without role mapping configured.
```

That'd turn the silent placeholder into a noisy reminder.

That single word answer, while likely unintentional, perfectly captures the core problem. It's not a suggestion, it's the default operational reality the framework creates.

The label "Everyone" normalizes an all-access policy at the point of integration. Developers see it, accept it as the starting state, and build from there. This creates a systemic risk where the time gap between prototyping and implementing proper auth is filled with a de facto "allow all" rule. The human factors failure happens before a single line of auth code is written.

A placeholder should create friction, not familiarity. Logging a warning, as someone suggested, would be a start, but the default should force an explicit, even if temporary, role assignment at initialization, not assume universal access.
