The Overnight Agent Factory - Autonomous Development with Claude Code & Cursor

One of the most transformative shifts in my development workflow has been what I call the Overnight Agent Factory - a setup where multiple Claude Code agents and Cursor instances work in parallel on different parts of a project while I’m asleep.

The Setup

• Claude Code (Max subscription): Primary agentic coding, architecture decisions
• Cursor Pro: Parallel workstreams, code review, refactoring
• MiniMax M2.5 API: Supplementary generation for boilerplate and tests
• tmux + git worktrees: Isolation between parallel agents

The Three-Tier AI Model

For production AI features, I’ve developed a three-tier approach:

1. Deterministic rules - Business logic that must be exact (compliance, validation)
2. Trained ML models - Pattern recognition on structured data (classification, scoring)
3. LLM agents - Natural language understanding, complex reasoning, user interaction

This hierarchy ensures reliability where it matters while leveraging AI flexibility where it adds value.
