## What it does

Give Norma two quantity snapshots and the scope they represent. Norma matches comparable tags and units, reports differences and leaves missing or ambiguous quantities unresolved.

## Install

Connect Arch Studio in Claude or ChatGPT, then return to your conversation and ask Norma for the task. Your assistant uses its available file access and tools to carry out the skill.

## 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 reconcile these Level 2 snapshots: the drawing ledger counts 12 CH-01 and the schedule lists 14, both in each. The drawing has no row for CH-02. Show differences without changing either source.
```

## What it compares

### Matching scope

Norma checks that building, floor, phase, revision and units describe a comparable selection.

### Exact quantities

Norma compares exact keys and requires duplicate or alias ambiguity to be resolved before aggregation.

### Differences and gaps

Norma reports deltas, unmatched rows and unknown quantities. A missing row is not treated as zero.

## Workflow

1. **Align** — Norma checks the source scope and units.
2. **Compare** — Norma matches the supported records and calculates the differences.
3. **Report** — Norma returns a read-only comparison; you decide whether a source needs correction.
