Summary

Move beyond simple prompting by designing autonomous AI agent loops that can trigger, execute, and validate their own work. Learn to implement heartbeat, cron, hook, and goal-based loops using Claude Code and Codex.

Topics

  • AI Agents
  • Claude Code
  • Codex
  • Loop Engineering
  • Automation
  • Software Engineering
  • Prompt Engineering
  • Subagents

Highlights

  • Main idea: Transition from manual prompting to autonomous loops where agents trigger themselves via schedules or events
  • Practical takeaway: Use the 'onboarding an employee' mental model to design loops with work trees, skills, and state tracking
  • Failure mode: Goal-based loops can rapidly burn tokens if validation criteria are too thin or imprecise
  • Technical pattern: Implement 'heartbeat' and 'cron' loops for routine tasks like daily PR reviews or morning briefings
  • Advanced technique: Use subagents within loops to perform real-time validation and complex task decomposition
