Mert Sniper

What this skill does

Near-expiry conviction trading on Polymarket. The skill scans markets in their final minutes, filters for strongly-skewed splits (60/40+), and places bounded trades against the under-priced side. Defaults — $10 max per trade, 5 trades/run, 8-minute expiry window, dry-run unless `--live`.

Mert Sniper is part of the Developer Tools category — developer tools that help your agent write, review, debug, and ship code. You can install it on its own or alongside other developer tools skills from the OpenClaw catalog.
