Published customer terms

get_customer_policy
Read-onlyIdempotent

Use this when checking Samuelz Chauffeur lead time, account requirements and booking confirmation terms. Do not use for service coverage (use get_service_options instead). Returns available with observedAt and terms, or unavailable. Lead time is in minutes; interpret dates in the returned time zone and revalidate terms on the eventual offer. This cheap, repeatable read creates nothing. Pass a published offerKey for its location’s terms; omit it for default policy.

Input Schema

NameRequiredDescriptionDefault
localeNoCustomer-requested language for text and links: en (default) or de. Preserve it on retries and related calls; it changes presentation, never price or eligibility.en
offerKeyNoOptional published supplier offer key, for example service_airport. Pass only a key supplied by the provider’s published context; otherwise omit to use the configured default. Preserve it across related calls and retries. It selects a service location and terms, not a booking ID or access grant.

TDQS

A4.8/5.0
Behavior5/5

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

Annotations already declare readOnlyHint/idempotentHint and non-destructive behavior, and the description reinforces this with 'cheap, repeatable read creates nothing'. It goes further by disclosing the response contract (available with observedAt and terms, or unavailable), the unit of lead time, time-zone interpretation, and the instruction to revalidate terms against the eventual offer.

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?

The when-to-use clause is front-loaded and each subsequent sentence carries a distinct rule (exclusion, return shape, units, offerKey routing). It is dense but slightly overpacked, and 'cheap, repeatable read creates nothing' partly repeats what the annotations already say.

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 two-optional-parameter read with full schema coverage, an output schema, and rich annotations, the description covers routing, return shape, units, and staleness handling. Nothing an agent needs in order 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.

Parameters4/5

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

Schema coverage is 100%, so the schema already carries most of the burden; the description adds the decision rule for offerKey (pass a published key for that location's terms, omit for the default). It says nothing about locale, which is left entirely to the schema, keeping this from a 5.

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 description names the exact resource (Samuelz Chauffeur lead time, account requirements, booking confirmation terms) and what the tool returns (policy with observedAt and terms, or an unavailable status). It explicitly distinguishes itself from get_service_options, so an agent can separate it from its siblings 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 Guidelines5/5

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

It states when to use it ('when checking … lead time, account requirements and booking confirmation terms'), when not to ('Do not use for service coverage'), and names the alternative tool. It also gives per-call routing guidance: pass offerKey for a location's terms, omit it for the default policy.

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