Overview & Result
Intercepts every tool call, file edit, or command execution from autonomous agents. Evaluates the action against security policy in milliseconds, preventing prompt injection attacks and destructive shell executions.
How Jev fits in the loop
- Intercept agent tool invocation payload.
- Jev scores risk against dangerous file deletion, privilege escalation, and credential theft patterns.
- Allow execution, request human approval, or terminate agent run.
How to reproduce
- Inspect the source implementation at https://x.com/isNickMa/status/2100566407524344225.
- Configure local Jev API credentials and register required tool/model bindings.
- Execute test prompts and observe decision latency and routing outputs.
Why this build matters
Critical security perimeter for autonomous agents executing shell and file commands.
Limitations
- Metrics are author-reported from the initial release unless independently verified.
- Requires access to the respective agent framework or runtime environment.
- Generative model execution remains external to the Jev decision step.
