Simulate the way your agent picks skills, and find out which skill steals whose tasks. Before your users find out.

The problem

Agent runtimes like Claude Code and Codex load skills by reading one or two lines of description. When a task comes in, the agent picks whichever skill sounds closest.

That works fine until two descriptions overlap. In our hospital demo, a booking skill's description claimed it also handled "vision report inquiries". The report-reading skill owned that job. So a patient asks for a report reading, the booking skill answers, and then it makes things up. Nothing errors, and nothing gets logged. We only found out because patients complained.

SkillSeam replays that selection process before you ship. On a 40-task demo with 6 skills, it exposed 4 planted conflicts at 5/5 vote consistency, and every clean task passed. Each conflict report points at the exact keywords in the thief's description that caused the theft.
