Create a direct checkout URL for one or more store products (Wix Stores). The user clicks the URL to complete payment on the site — no login required on the AI agent side.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, description conveys key behavior: creates a URL, user completes payment, no login needed. Does not detail return format or potential errors, but covers main safety and interaction aspects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no fluff. The core purpose and key usage detail (no login) are front-loaded. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequate for a simple tool with one parameter, but missing return format and error conditions. With no output schema, the description should ideally state what the tool returns (e.g., a URL).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% coverage with clear descriptions for each parameter (items, productId, quantity). Description adds no extra nuance beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the verb 'create', the resource 'direct checkout URL', and the scope 'for one or more store products (Wix Stores)'. It distinguishes from sibling tools like list_products or create_booking by focusing on payment URL generation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implied usage: use when needing a checkout URL for products. Notes that no AI agent login is required, but lacks explicit when-to-use vs. alternatives or exclusion criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
All 28 tools have clearly distinct purposes. Overlaps like create_booking vs request_reservation are well-delineated by descriptions: one for appointments with checkout URL, the other for table requests via email confirmation. Similarly, reserve_event_tickets vs rsvp_event, and get_restaurant_menus vs search_dishes are complementary.
Tool names follow a consistent verb_noun pattern in snake_case (e.g., create_booking, get_availability, list_events, search_places). Verbs indicate action type (get/list for retrieval, create/reserve for creation), and nouns are specific entities. No mixing of conventions.
28 tools is above the typical 3-15 range but appropriate for the broad scope of a neighborhood directory with multiple Wix integrations (Bookings, Events, Stores, Reviews, etc.). Each tool covers a distinct feature, and no tool feels redundant.
The tool surface covers the main user workflows: searching places, viewing details and menus, checking availability, making bookings/reservations, and managing event tickets. Minor gaps exist (e.g., no update/cancel for bookings, no booking status check), but these are acceptable as the server focuses on initiating actions.
