SS33 Skill Store
Find the right verified skill
Let your agent find the right verified skill at the right time. SS33 Skill Store is a searchable library of more than 60,000 agent skills: step-by-step procedures written by practitioners and organisations. Hundreds are Verified: tested on blind everyday questions, where the skill measurably improved the model's answers. Describe your task in a sentence and the store finds the closest skills and returns the one that fits: the procedure, the rules and numbers that matter, and the common mistakes to avoid. When nothing fits well, the search says so instead of returning a weak match. Areas include software development, AI and agents, data and analytics, security, business, finance and markets, legal, health and life sciences, creative and media, science and education, and personal and home.
