Describe the solution you'd like

I’ve been experimenting with a lightweight runtime mediation layer for agent execution systems.

Core idea:
generation != release authority

Instead of treating every generated tool/action call as implicitly authorized, introduce a bounded runtime release-control layer between:

candidate generation
→ execution authorization

The mediation layer exposes tri-state runtime decisions:

• PROCEED
• NEEDS_REVIEW
• SILENCE

The goal is not to block autonomous workflows entirely.

The goal is introducing a lightweight execution review boundary before unstable, unsafe, or high-risk execution paths.

This becomes especially relevant for:

• external tool execution
• browser actions
• shell/code execution
• long-running autonomous crews
• recursive task delegation
• multi-agent execution chains

Potential integration points could include:

• tool-call authorization hooks
• runtime middleware
• task execution mediation
• execution policy evaluators
• bounded human-review escalation

I recently built a small live runtime demo around this direction:

Curious whether CrewAI contributors are exploring similar runtime governance / execution mediation patterns for production-grade agent systems.

Describe alternatives you've considered

Most current systems appear to rely on:

• prompt-level alignment
• post-execution validation
• static permission systems
• sandbox isolation

The issue is that generation itself often becomes implicit execution authority.

I’m exploring whether a separate runtime release layer can reduce unsafe-path execution without fully removing agent autonomy.

Additional context

This is not intended as:

• AGI framing
• full autonomy suppression
• centralized policy enforcement

More as:
runtime execution mediation
+
bounded release governance
for agent/tool execution systems.

Willingness to Contribute

Yes, I'd be happy to submit a pull request

No file, test, or concrete entry point is named. Start by locating the tool-call authorization hooks, runtime middleware, task execution mediation, and policy evaluators mentioned in the issue. Define the PROCEED, NEEDS_REVIEW, and SILENCE behavior and tests before implementation; done requires an agreed integration boundary.
