How do I practice health behavior agents?

The most direct way to practice health behavior agents is through a focused exercise: Identify the health domain where you currently spend the most decision energy — sleep, exercise, nutrition, or stress management. Write one agent for that domain in full trigger-condition-action format. Be precise: specify the exact trigger (a time, a sensation, an environmental cue), the condition that must be true for the agent to fire, and the concrete action the agent performs. Then identify the single most likely failure scenario — the situation where you would override the agent — and write an if-then contingency plan for that scenario. Deploy the agent tomorrow and run it for seven consecutive days, noting each day whether it fired, whether you complied, and what happened.

Common pitfall: Designing health agents that are too ambitious or too numerous for your current stage of readiness. You write agents for perfect sleep hygiene, daily intense exercise, pristine nutrition, and elaborate stress protocols — all at once. None of them survive first contact with your actual life. The fix is Prochaska's insight applied to agent design: match the agent's scope to your current stage of change. If you are in contemplation for exercise, your agent is not 'run five miles daily.' It is 'put on running shoes and step outside.' Scale the agent to where you actually are, not where you wish you were.

This practice connects to Phase 21 (Agent Fundamentals) — building it as a repeatable habit compounds over time.
