pinchtab-stealth-score

Run the PinchTab stealth-score sweep against 15 bot-detection / fingerprint sites (sannysoft, rebrowser, deviceandbrowserinfo, iphey, whoer, browserscan, pixelscan, fingerprint-scan, incolumitas, fvision, amiunique, browserleaks, creepjs, coveryourtracks, fingerprint-demo). Starts a Docker PinchTab container per browser (chrome / cloak / both), spawns a blind agent that drives PinchTab through plain-English per-site playbooks, captures structured metrics, prints a side-by-side comparison highlighting divergent metrics, and appends to history.jsonl for cross-session tracking. Use when asked to 'run stealth score', 'compare cloak vs chrome detection', 'measure stealth', or '/pinchtab-stealth-score'.

migrate-to-1.0

Migrates a Kotlin project from Exposed 0.61.0 to Exposed 1.0. Scans Kotlin sources and build files, applies the mechanical changes documented in the official 1.0 migration guide (package renames, JDBC module moves, SqlExpressionBuilder lambda → top-level imports, build dependency bumps), and produces a report of items that need manual review. Use when the user wants to upgrade an existing Exposed 0.61.0 project to 1.0; for older 0.x versions the skill emits a compatibility warning and proceeds only with user confirmation.
