What problem does it solve? Running delegated agent tasks on the head node lacks isolation and scalability. This Skill guides the configuration of Union Street agents to execute inside isolated Vercel Sandbox microVMs, handling authentication, persistence, and Lash runtime wakeups correctly. ## Core Features & Use Cases - Auth Mode Selection: Choose between native OIDC (via VERCEL_OIDC_TOKEN) and access-token auth requiring VERCEL_TEAM_ID, VERCEL_PROJECT_ID, and VERCEL_TOKEN, with strict rules against partial configuration. - Runtime Wake Shape: Create or resume a sandbox, start the Union Street runtime API inside it, expose the control port, and call POST /api/peers/:target/wake while preserving caller, message, trace, thread, chain, and wakeKind. - Persistence Policy: Default to ephemeral sandboxes for one-off delegated tasks, use named persistent sandboxes only when explicitly configured, prefer snapshots for warm starts, and tag sandboxes with unionstreet, profile, plugin, and trace labels. - Use Case: A manager agent delegates a compute-heavy task to a direct report; the provider spins up a tagged ephemeral Vercel Sandbox, wakes the agent over Lash, and tears the sandbox down after the result returns. ## Quick Start Ask the agent to configure a Union Street profile to run delegated tasks in a Vercel Sandbox using OIDC auth and ephemeral sandbox persistence.
