okYestrue = use summary, canonicalUrl, and extra keys. false = do not invent data; read error + hint and retry with valid args or open hint.
faxNoFax display.
hintNoPresent when ok=false. Absolute URL the agent should open or pass to get_ai_page / get_discovery.
toolYesEcho of the tool name that produced this object (e.g. get_service_area).
emailNoPublic info@ email.
errorNoPresent when ok=false. Codes include: unknown_tool, unknown_place, unknown_auswahl, unknown_ratgeber, unknown_doc, unknown_discovery, faq_not_found, wissen_not_found, serp_not_found, q_required, bad_datetime, bad_when_key, plus HTTP errors from fetch.
localeNoLocale actually used for URLs (args.locale or de).
mobileNoMobile display (Handy), 24/7.
addressNoOffice postal address (no walk-in).

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, but the description adds a real behavioral safeguard beyond them: it does not submit the website contact form and the agent must not claim it did. It also implies an object return. It stops short of disclosing response structure or whether fields can be null/absent, so not a full 5.

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?

The WHAT / DOES NOT / USE / NEXT labeling front-loads the essential information and each clause earns its place with zero filler. Well-sized for a single-parameter read tool.

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?

With an output schema present, the return shape need not be explained, and the enumeration of fields plus the form-submission caveat cover the agent's needs. Nothing required to call it correctly is missing.

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 single 'locale' parameter is thoroughly documented in the schema itself (enum values, URL prefix behavior, default). The description does not touch locale at all, so the baseline 3 is the correct score.

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?

The WHAT clause names the exact resource returned (public phones, fax, email, office address object), and the DOES NOT and NEXT clauses clearly distinguish this read-only contact tool from the compose_* siblings. An agent can tell what it gets and what it is not.

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?

Explicit 'USE to give the user a number' plus a concrete NEXT list (compose_tel_mobile, compose_tel_landline, compose_mailto, compose_whatsapp, list_whatsapp_options) routes the agent to the right follow-up tools. It also gives an explicit exclusion (does not submit the contact form).

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