Get the full details for a specific product on authority.md: a persona framework, a functional Tool, a Playbook, or a curated Bundle. Use after search_personas to show complete information before purchase. Returns metadata, a 'type' field, and a preview of the content. Accepts persona slugs (e.g. 'warren-buffett'), Tool slugs (e.g. 'decision-brief'), Playbook slugs (e.g. 'invoice-chase'), and Bundle slugs (e.g. 'founder-stack'). For bundles, returns the full list of persona slugs needed to call purchase_persona.
DiscoveredList all categories of thinkers available on authority.md. Use when the user wants to browse by domain (Investor, Tech Visionary, Philosopher, etc.) rather than search by name.
DiscoveredGenerate 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.
DiscoveredSearch 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.
