Vercel launched Eve, where every agent is a directory of files.

Vercel shipped Eve, an open-source TypeScript-native agent framework, on June 17 at Ship 26 in London. Every agent is a directory of files that compiles to a durable production service on Vercel Functions: session state persisted and replayed via Vercel Workflow, sandboxed compute via Vercel Sandbox, OpenTelemetry observability on by default. It's model-agnostic, routing through Vercel's AI Gateway. The "agent as a directory of files" idea echoes how Claude Code skills already work, and the model-agnostic routing is the same provider-agnostic theme as OpenCode and GLM-5.2. The pattern is hardening across the whole ecosystem this week.
