OpnSkin Trade Assistant troch OpnSkin

OpnSkin Trade Assistant streamlines peer-to-peer CS2 skin trading on opnskin.com.

Features:
- Automatically selects the correct item in Steam trade offers
- Intercepts trade creation to track offer IDs
- Monitors Steam Guard mobile confirmation via Steam API
- Tracks escrow status and detects trade reversals
- Syncs your Steam inventory with opnskin.com
- Works alongside other Steam extensions (CSFloat, SIH, etc.)

How it works:
When you sell a skin on opnskin.com, the extension opens the Steam trade offer page, finds the right item in your inventory, and adds it to the trade. After you click "Make Offer", it monitors the trade status through the Steam API until completion.

Permissions explained:
