# Back Pressure

## Why Back Pressure Matters

**Back pressure** = automated feedback that validates agent work

<VClicks>

- Without back pressure, **you** become the validation layer
- Agents cannot self-correct if nothing tells them something is wrong
- With good back pressure, agents detect mistakes and iterate until correct

## Back Pressure Sources

| Source | What It Validates |
|--------|-------------------|
| **Type system** | Types, interfaces, contracts |
| **Build tools** | Syntax, imports, compilation |
| **Tests** | Logic, behavior, regressions |
| **Linters** | Style, patterns, best practices |

**Key insight:** Expressive type systems + good error messages = agents can self-correct.
