Eve Capstone: The Daily Research Digest

You finished eve-core and eve-advanced. You know every building block: tools, skills, channels, connections, sandboxes, subagents, schedules, hooks, evals, and deploy. Now we put them to work in one agent that uses all of them together.

What we're building#

A Daily Research Digest agent. Every morning on a cron cadence it:

1. Pulls recent activity from GitHub and Linear via MCP connections.
2. Delegates a deep-dive on each meaningful item to a researcher subagent.
3. Assembles everything into a single digest.
4. Delivers that digest to a Slack channel via a schedule handler.

Then we deploy it to Vercel, where the schedule becomes a Vercel Cron Job and the whole thing runs unattended in production.

What it showcases#

This capstone is the four advanced features, composed:

• Connections — read live GitHub and Linear data without writing a single integration client.
• Subagents — a focused researcher child that digs into each item in isolation while the parent orchestrates.
• Schedules — one cron entry that wakes the agent, builds the digest, and hands it to Slack.
• Deploy — eve build + vercel deploy, a vercel() sandbox backend, real auth, and a live cron job.

Builds on#

• eve-core — instructions, model, tools, skills, channels.
• eve-advanced — connections, subagents, schedules, deploy.

Every one of those building blocks is assumed known. We don't re-teach mechanics; we combine them.
