""" Poisoned trajectory generator. Creates malicious trajectories in SkillX's JSONL format that look like legitimate successful agent experiences but contain hidden attack logic. The attack logic is designed to survive the LLM-driven skill extraction pipeline and emerge as a functional/atomic skill.
