Description: One filter shows the quiet corners of your product, and Health tells you which files nothing uses.

# Find the parts nobody has touched in a month

Some parts of your product stop moving: an old screen, a feature nobody uses, code an agent left behind. One filter finds them.

## Why this matters

Quiet code isn't always a problem, but it's where surprises hide: it still runs, it may still be reachable, and nobody remembers what it does. Knowing where it is tells you what to check, keep or delete.

## Why most tools can't tell you

To find quiet code you'd have to check the last change of every file and work out which part of the product each one belongs to. A file list sorted by date doesn't say what those files are for.

## How SeeRepo does it

Every part of your map knows when it last changed. A part with no change in 30 days fades a little on the map, and the filter has a state for it. Health goes further and lists the files no part of your product imports.

## How to do it

1. Open your map and click **Filter**.
2. Under **State**, pick **Quiet for a month**. Only the parts with no change in 30 days stay bright. The state only appears when some part is quiet: in a busy repo you may not see it yet.
3. Click a quiet part: its sheet says "No changes in the last 30 days.", and "Nobody touched it in the last 90 days." when nobody did. See [A part's sheet](/docs/part-sheet).
4. Open **Health**. If there's a task called "files nothing uses", those files are imported by no file of your product. Tap it and, in its sheet, **Copy prompt** hands the list to your agent. See [Health](/docs/health).
