Bay Area Mobile Dog Wash Booking

book_wash

Request a mobile dog wash at one of the times from get_available_slots. IMPORTANT: this files a booking REQUEST — the owner confirms it shortly afterward and the customer then receives the confirmation email; tell the user that. Confirm the exact time (Pacific Time), name, email, service address, and dog size before calling. First-time customers can use promo code WASH10 ($10 off) — apply it for them. Fill optional fields from conversation; don't interrogate.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

Name	Required	Description
`name`	Yes	Customer's name.
`email`	Yes	Customer's email (confirmation arrives here after owner approval).
`notes`	No	Anything else: parking notes, gate codes, coat condition, skunk emergency, behavior notes.
`phone`	No	Customer's phone — strongly recommended so the owner can reach them.
`promo`	No	Promo code. Use WASH10 for first-time customers.
`start`	Yes	Chosen slot start as a UTC ISO string, exactly as returned by get_available_slots.
`addons`	No	Optional add-ons the customer wants.
`address`	Yes	REQUIRED: the service address where the van comes (street, city).
`dog_name`	No	The dog's name (nice to have).
`dog_size`	Yes	Dog size tier — sets the price. Ask weight/breed if unsure (Small <20 lbs, Medium 20–60, Large 60–100, XL/Giant 100+).

A4.1/5.0

Behavior4/5

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

No annotations are provided, so the description carries the full burden, and it discloses the non-obvious async behavior: this files a REQUEST, the owner confirms shortly after, and the customer then gets the confirmation email — plus an instruction to tell the user. It still omits failure modes, duplicate-booking behavior, and cancellation policy, so it is strong but not exhaustive.

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

Conciseness4/5

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

Front-loaded with the purpose and the most operationally important caveat (it is a request, not a confirmed booking). Every sentence carries actionable content, though the promotional instruction and the 'don't interrogate' aside are slightly conversational padding.

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

Completeness4/5

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

For a 10-parameter mutation tool with no annotations and no output schema, the description covers the workflow, what to verify pre-call, the promo, and how to populate optional fields. It leaves pricing implications beyond dog_size, add-on selection and expected response/error handling unspecified.

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

Parameters3/5

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

Schema description coverage is 100% and the schema already explains start (UTC ISO from get_available_slots), dog_size tiers with weight bands, notes, and the promo field with WASH10. The description mainly restates the promo guidance and adds only the 'fill optional fields from conversation' steer, which is marginal value over structured data.

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?

States a specific verb and resource ('Request a mobile dog wash') and ties the timing input to the sibling tool that produces it ('at one of the times from get_available_slots'). An agent can distinguish this booking action from get_available_slots and get_services without opening any schema.

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

Usage Guidelines4/5

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

Gives clear sequencing (must pick a time returned by get_available_slots) and explicit preconditions (confirm exact PT time, name, email, address, dog size before calling; pull optional fields from conversation without interrogation). It does not name when-not-to-use or point at get_services for add-on discovery, so it stops short of full routing guidance.

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