# ConstraintFirst

Defining boundaries before content

Layer: Mind · Category: Strategy

## Mechanism

The agent first generates the 'negative space' (the [Constraint](https://mindscape.pages.dev/bootstrap/Constraint.md)s, safety rules, and format requirements), defining a rigid container. Only THEN does it generate the content to fill that container. It separates 'form' from 'function'. This prevents the generation of content that is creative but invalid.

## Invariants

- The [Constraint](https://mindscape.pages.dev/bootstrap/Constraint.md) set is generated before any content.
- Constraints are fixed for the duration of a generation pass; revising them starts a new pass.

## Failure modes

- Over-constraining the solution space.
- Retrofitting: constraints are loosened mid-pass to admit content already generated, which reverses the pattern.
