Could you build this?

Partial The plugin for CTFd, a Python/Flask platform, is buildable as a vibe-coded activity-logging and rule-based anomaly tool. Reliably detecting AI agents and scripted play requires behavioral modeling and tuning on real competition data that a solo builder lacks.

What it would actually take: The architecture is a CTFd plugin that hooks submission and activity events, stores them, and runs rule-based checks such as timing, shared-IP, and flag-brute-force heuristics. The hard part is a credible AI-agent or bot classifier, which needs labeled behavioral data from real CTFs and careful threshold tuning to avoid false positives. That requires security-competition and data-analysis expertise.
