# Path Params

Read the changing pieces of a URL, including the awkward ones

## What this does

URLs carry values in them - an id, a file path, a language code - and each shape needs declaring before you can read it. This covers dynamic segments, catch-all segments, optional ones, and segments with a prefix or file extension attached. It also covers reading those values out and controlling how they are parsed and which characters are allowed.

### Top 3 things it does for you

- Read a dynamic segment out of the URL
- Match everything under a path
- Make a segment optional

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## Questions

### Is Path Params safe to install?

AIR scanned this exact version of Path Params and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 179d9b9b5eec, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/path-params.

### How do I install Path Params?

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