Introducing Eve

Takeaways

• Eve (Vercel, open source) is an agent framework with production primitives built in: durable execution, sandboxed compute, HITL approvals, subagents, evals, tracing, channels, schedules.
• Design thesis: an agent is a readable directory — agent.ts, instructions.md, tools/, skills/, subagents/, channels/, schedules/ each describe one concern.
• Positions itself as Next.js for agents — stop hand-rolling the same plumbing per agent; provider fallbacks via AI Gateway.
• defineAgent({ model }) + markdown instructions = minimal bootstrap; tools are TypeScript files; skills are knowledge markdown separate from tools.
• Supports Slack channels, cron schedules, and delegation to subagents — aimed at data/analyst and ops agents running in production.
• Vercel dogfoods Eve for internal agents — framework + hosting story similar to their web stack.

Notes

Production-grade agent framework alternative to ad-hoc Claude Code / MCP setups — relevant when ObsidianOS skills need durable cloud execution beyond local vault agents.

Open questions

• Does Eve’s directory-as-agent model map to ObsidianOS skill folders, or is local markdown + MCP sufficient for Ben’s use case?
