## Usage

Ask Norma in plain language. With Arch Studio connected through MCP, no $ or / command is required. Norma is your assistant working with Arch Studio.

```text
Use Arch Studio to draft an environmental documentation requirement for this material using the reviewed EPDs and our brief. Keep the evidence links and flag any missing target rather than inventing a carbon limit.
```

## What it drafts

### Evidence requirements

Norma identifies the environmental documentation needed for the selected material scope.

### Performance clauses

Norma uses explicit project criteria and applicable original sources when drafting proposed requirements.

### Review items

Norma leaves missing targets and unsupported comparisons open rather than inventing a carbon limit.

## Workflow

1. **Read** — Norma reviews the accepted declarations and project criteria.
2. **Draft** — Norma prepares the proposed clauses with evidence links.
3. **Review** — You review the requirements and resolve the flagged criteria before using the draft.
