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, the description must disclose behavioral traits. It states that the user completes payment and no agent login is needed, but it does not mention side effects (e.g., inventory reservation, expiration), response format, or error conditions. Adequate but not deep.
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. First sentence states purpose, second adds key context. 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?
The description lacks information about the return value (a URL?) and error handling. The schema mentions dependency on list_products, but the description could be more complete. Output schema is absent, so more context would help.
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?
Schema coverage is 100% with clear parameter descriptions. The tool description does not add extra meaning beyond the schema, so it meets the baseline without exceeding it.
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?
The description clearly states the tool creates a direct checkout URL for Wix Stores products, differentiating it from sibling tools like create_booking or reserve_event_tickets. It specifies the action and resource precisely.
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?
The description explains when to use (to purchase store products via a checkout URL) and notes that no login is required for the AI agent. However, it does not explicitly exclude alternatives or provide when-not-to-use guidance.
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.
Each tool targets a distinct domain (bookings, store, events, restaurants, movies, etc.) with detailed descriptions that clearly differentiate their purposes. Overlap is minimal and handled by context, such as create_booking vs create_checkout vs request_reservation.
All tools follow a consistent verb_noun pattern in snake_case, using prefixes like get_, list_, create_, search_, etc. The naming is predictable and makes it easy to infer the action and resource.
28 tools is above the typical well-scoped range, but each tool covers a distinct feature of the neighborhood directory (places, events, movies, blog, forms, etc.). The count reflects the integration of multiple Wix apps, which is appropriate for a comprehensive directory.
The tool set covers most user-facing operations for a directory: search places, get details, book services, events, restaurant menus, etc. Minor gaps exist (e.g., no cancellation for bookings, no update operations), but these are likely out of scope for a public-facing server.
