create_booking

Book an appointment slot at a venue (Wix Bookings). NOTHING IS BOOKED UNTIL THE CUSTOMER PAYS: this returns a checkout URL, and the booking stays off the venue's calendar until a human opens that URL and completes payment on the venue's own site. Tell the user they must open the link. Call get_availability immediately before this — the slot is re-validated server-side and a taken slot is rejected. The contact email is NOT verified at this step; the checkout is what confirms it.

A5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Despite no annotations, the description fully discloses behavior: nothing is booked until payment, returns a checkout URL, booking stays off calendar, server-side slot re-validation, and email not verified. No hidden behaviors.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

All sentences are substantive and well-organized: upfront purpose, critical warning in caps, usage prerequisites, and parameter hints. No fluff; each line earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a complex tool with 6 parameters, nested objects, no output schema, and important side effects, the description covers the entire flow: preconditions, behavior, post-conditions, and user action required. It is complete for effective use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, but description adds valuable context: ties startDate/endDate to get_availability, serviceId to list_booking_services, place_slug to search_places, and explains contact requirements. This greatly aids parameter selection.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the verb 'Book an appointment slot at a venue (Wix Bookings)'. It distinguishes from siblings by emphasizing that nothing is booked until payment, which sets it apart from tools like request_reservation or get_availability.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit instructions: call get_availability immediately before, inform user about the checkout URL, and notes that contact email is not verified. It also warns about slot re-validation and rejection, covering when and how to use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4/5.0
Disambiguation5/5

Each tool targets a distinct resource or action (booking, checkout, availability, events, reviews, etc.). Even similar-looking tools like create_booking, request_reservation, and rsvp_event are clearly differentiated by their descriptions and target systems.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern in snake_case (e.g., create_booking, get_availability, list_booking_services). No mixing of conventions or unclear verbs.

Tool Count4/5

28 tools is on the higher end, but the server covers a wide domain (places, events, movies, booking, forms, loyalty, etc.). Each tool serves a clear purpose, so the count is justifiable, though minor trimming could be considered.

Completeness4/5

The tool set covers most workflows for a neighborhood directory: search, details, booking, events, reviews, etc. Some CRUD operations are missing (no update/delete for bookings), but these are consumer-facing actions where that is acceptable. The domain is well-covered.
