What is resource contention?

Example: You have a two-hour block on Saturday morning. Your reading agent wants to finish a book chapter. Your writing agent wants to draft a newsletter. Your fitness agent wants a long run. Your family agent wants to make breakfast with the kids. Each agent has a legitimate claim. Without allocation rules, the loudest agent wins — which is usually the one generating the most guilt or anxiety, not the one producing the most value. Compare this to someone who defines a fixed rotation — Week 1 fitness, Week 2 writing, Week 3 reading, Week 4 family — with the constraint that the active agent owns the block completely and the others must wait without generating interrupts. Same two hours. One system thrashes between tasks and accomplishes fragments. The other completes meaningful units because contention was resolved before execution began.

This concept is part of Multi-Agent Coordination in the How to Think curriculum.
