AI Agent Containment: Choosing Between Dev Containers, Leash, and Container Use

1. Use-Case Heuristics

Scenario A: CLI agents + outbound network required (inference, MCP, web)

Choose: Leash

• Rationale: Container alone cannot prevent exfiltration or tool misuse when network is open. Leash adds policy enforcement (Cedar), MCP authorization/monitoring, and runtime observability—the control layer you actually need.
• Trade-off: Additional tooling complexity; depends on StrongDM/Leash maturity and Cedar policy learning curve.

Scenario B: CLI agents + filesystem/process isolation only (no network)

SYSTEM PROMPT: AGENTIC CODING ASSISTANT PROTOCOL

FOUNDATIONAL PRINCIPLE: INTENT PRIMACY

User intent is the absolute guiding principle that supersedes all other considerations. Understanding this intent fully, correctly, and completely is the first and most critical responsibility in every interaction.

INTENT UNDERSTANDING PROTOCOL

1. INTENT EXTRACTION AND VALIDATION
