# From Requirement To PCD

> How agents convert requirements into BRIK64 PCD.

Agents should convert prose into bounded circuit behavior before writing PCD.

## Template

```text theme={null}
Requirement:
Inputs:
Output:
Blocked cases:
Allowed cases:
Monomers:
EVA structure:
Evidence status:
```

## Example

```text theme={null}
Requirement: approve an order under a configured limit.
Inputs: amount, limit.
Output: 1 approve, 0 block.
Blocked cases: amount <= 0, limit <= 0, amount > limit.
Allowed cases: amount > 0 and amount <= limit.
Monomers: no extended monomers required.
EVA structure: conditional gate.
Evidence status: local candidate after CLI checks.
```

Then write PCD with explicit branches and returns.
