085

Security & Guardrails MIT source reviewed

A Pi extension that flags tool risks before execution and checks output for secrets and failure types.

JEV · Decision point

Jev scores destructive actions, scope and output risks; configuration chooses warnings or confirmation.

Defaults to shadow mode and fails open on API errors; it is not a standalone security boundary.

SDK & Decision Frameworks MIT source reviewed

An Effect Agent TypeSafe decision provider for typed question sets and optional model selection.

JEV · Decision point
