Declarative Privilege Boundaries for Multi-Agent Workspaces

Allowing autonomous agents unconstrained file-system access exposes sensitive private vaults and system credentials to accidental modification or exfiltration. Declarative containment harnesses enforce strict read/write boundaries per agent session.

Containment Invariants

  • Namespace Isolation: Agents operate inside restricted workspace mounts where parent system directories remain strictly invisible.
  • Read-Only Reference Mounts: Foundational documentation and configuration schemas mount as read-only layers to prevent unauthorized drift.
  • Pre-Execution Privilege Audits: The containment harness scans agent execution requests against security policy manifests before granting I/O access.

Strict privilege boundaries ensure autonomous agents operate safely within clearly defined operational limits.
