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

Annotations only say readOnlyHint=false, so the description carries the burden and does real work: it discloses that the call creates a contact-claim record, that RepuTend ops review it manually before anything is provisioned, and that the response is deliberately non-enumerating. That is meaningful behavior an agent cannot get from structured fields. It omits idempotency on repeat calls, whether the caller must be authenticated, and any rate limiting.

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

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

Three short sentences, front-loaded with the action, then the side effect, then the response guarantee. Nothing is redundant or padded. The trailing '(capability: access.request)' is inert metadata but costs almost nothing.

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

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

For a two-parameter, no-output-schema mutation, the description covers the workflow and the response-safety property well. It does not say what the caller gets back (request id, status, confirmation email) or what to do next after submitting, which an agent needs to close the loop.

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

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

Schema description coverage is 0%, so the description must supply parameter meaning and only does half the job. 'Trustpilot business domain' implies tp_domain is a bare domain rather than a URL, but no format example is given, and contact_email is never mentioned at all despite being required.

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

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

The description gives a concrete verb and object: requesting RepuTend (access) for a Trustpilot business domain, and clarifies it records a contact claim rather than provisioning anything. That is specific enough to separate it from every sibling (all of which operate on cases, filings, packets, or teams). It stops short of a 5 only because 'RepuTend' itself is never defined for an agent that may not know the product.

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

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

Usage is implied rather than stated: an agent can infer this is the entry point when a business you want to work with is not yet set up. The note that the answer is identical whether or not the business already uses RepuTend is a useful routing hint, but there are no explicit exclusions or named alternatives (e.g. onboarding_status or claim_packet) for an agent deciding between them.

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