}Generate a checkout URL on authority.md for purchasing one or more frameworks, Tools, Playbooks, or Bundles. Accepts 1-50 slugs (personas, Tools, and/or Playbooks, mixed carts allowed). To purchase a Bundle, pass all 10 of its persona slugs (get them from get_persona_details on the bundle slug — they will land on the $29.99 step-pricing tier automatically). Returns a URL the user follows to a checkout page hosted by authority.md that processes payment securely via Stripe. Personas use step pricing; Tools have individual prices; Playbooks are a flat $12.99 each. For current prices call get_persona_details per slug or read https://authority.md/products.json. Confirm with the user which items they want and the total cost BEFORE calling this tool.

}Search the authority.md marketplace. It carries four product types: persona thinking frameworks (e.g. Warren Buffett), hand-built functional Tools (e.g. Strategic Email — procedures for recurring tasks such as difficult emails, hiring, and pricing), Playbooks (systematically produced single-job procedures at a flat $12.99, e.g. Invoice Chase), and curated 10-persona Bundles (e.g. founder-stack, engineers-stack — $29.99 each). Use when the user asks about a specific person, a category, a task they want help with, or wants recommendations. Each result includes a 'type' field ('persona', 'skill', 'playbook', or 'bundle'), slug, focus, and price. For current prices read https://authority.md/products.json.
