## About Matter Update

This appends a dated event to a matter's history file and refreshes its row in the log, in one step.

It is meant for the ordinary movements of a matter: new developments, status changes, risk re-assessments, deadline shifts, and changes to settlement authority.

Use it when you want to log an update, note a development, or record a status change against the portfolio.

## Questions

### Is Matter Update safe to install?

AIR scanned this exact version of Matter Update and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 4d55f5396229, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/matter-update.

### How do I install Matter Update?

Open https://airmarket.ai/app/matter-update on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up.
