Sandbox Skill

Isolated execution environments for AI agents and testing workflows.

Philosophy

Lambda/Functions: Fast cold start, 15-min limit, stateless, per-ms billing
App Platform Sandbox: 30s cold start (or instant with pool), unlimited duration, stateful, per-hour billing

Sweet spot: Long-running, stateful, iterative workflows where agents need to
install packages, run code, check results, modify, repeat.
