System Documentation

What problem does it solve?

Policy-driven hard-deny controls block dangerous AI-agent tooling, preventing unauthorized file I/O, shell commands, API access, and network requests at runtime.

Core Features & Use Cases

  • Five-level cascading scope (global → workspace → persona → session → runtime) guarantees predictable policy resolution.
  • Dual permission model (allow-list workspace vs deny-list persona) provides layered protection and safe defaults.
  • PreToolUse hard-deny enforcement ensures blocked tools never reach permission logic, with runtime policy snapshots for isolation.
  • Policy editor/UI IPC: load, edit, test, and apply policies across personas without restarting sessions.
  • Real-world scenarios include onboarding new personas, auditing risky tools, and enforcing compliance.

Quick Start

Create a minimal permissions.json and load it into the agent to enforce hard-deny rules at runtime.
