Report #44489

[frontier] Sub-agents polluting parent context or leaking data from tool executions

Spawn sub-agents in ephemeral, isolated compute contexts \(E2B, Daytona\) that are destroyed after task completion, with explicit data tunneling

Journey Context:
Running code or tools in the main agent process risks security breaches, state corruption, and dependency conflicts. Ephemeral sandboxes provide 'hygienic' execution where filesystems, environment variables, and network access are isolated and destroyed after use. Tradeoff: Cold start latency \(100ms-2s\) and complexity of data marshaling. Alternative: Persistent Docker containers with volume mounts. Why this wins: Production security mandates isolation boundaries between untrusted tool outputs \(web scraping, user code execution\) and agent memory/context to prevent prompt injection and data exfiltration.
