Autonomous agents need guardrails, not line-by-line scripts

Autonomous does not mean uncontrollable.

Cogweald’s model can decide what happens next in a world. It cannot change the database schema, bypass authorization, arbitrarily rewrite published content, or turn unvalidated text directly into system state.

The guardrails live outside the model:

1. Output must match a structured schema.
2. World state can only change through the server-side persistence layer.
3. Character and thread transitions must follow defined rules.
4. A failed generation must not commit half of a world update.
5. Every tick has a claim guard to prevent duplicate execution.

The model gets creative freedom. The system owns consistency.

This is one of my favorite agent design principles: do not describe every rule in a prompt. If code can guarantee something reliably, let code guarantee it. Give the model the decisions that actually require semantic judgment.
