Read-onlyIdempotent

One named rooftop's store record: name, dealer group, OEM programs, location/contact metadata, and fee schedule. Pass rooftop_slug. Whether a specific unit's listed price already includes a fee varies per unit — quote_preview returns the estimated total. Fee schedules may be incomplete — an unlisted fee is not a guarantee that no such fee applies; confirm final charges with the dealer.

Input Schema

Name	Required	Description	Default
`rooftop_slug`	Yes

Output Schema

Name	Required	Description
`data`	No
`error`	No	Unknown and foreign thread ids are deliberately indistinguishable: both return invalid_params with message "unknown thread_id" (anti-enumeration).
`freshness`	No

TDQS

A3.9/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds real behavioral caveats beyond that: fee schedules may be incomplete, an unlisted fee is not a guarantee of absence, and whether a listed unit price already includes a fee varies per unit — all material to interpreting the result.

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?

Three sentences, front-loaded with what the record contains, then the parameter, then the fee caveats. Nothing is wasted, though 'Pass rooftop_slug' partially restates an already-required schema field, keeping it just short of maximally tight.

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?

An output schema exists, so return values need not be explained, and annotations cover the safety profile. The description still supplies the interpretive caveats an agent needs about fee data reliability, leaving only minor gaps (no auth/permission notes, no clarification of when the slug is not in hand).

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 0% for the single required parameter, so the description carries the burden. It names the parameter ('Pass rooftop_slug') and implies its meaning via 'One named rooftop', but adds no format, slug conventions, or constraint guidance beyond the schema's min/maxLength. Minimal but non-zero compensation.

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

Purpose4/5

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

The description identifies the resource precisely — a single named rooftop's store record — and enumerates what it contains (name, dealer group, OEM programs, location/contact, fee schedule), which differentiates it from list-oriented siblings like network_directory and network_search. However, no explicit verb is stated (the 'Get' only lives in the title), and it never directly contrasts itself with the directory/search siblings, so the differentiation is inferential rather than stated.

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?

It tells the caller to pass rooftop_slug and routes the pricing use case to quote_preview ('quote_preview returns the estimated total'), which is a genuine alternative selection hint. It stops short of explicit when-not-to-use guidance against network_search/network_directory for discovering rooftops when no slug is known, so it is clear context without full exclusions.

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