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

Annotations already cover the safety profile (readOnlyHint=true), and the description adds genuine behavioral detail beyond that: the evidence integration is 'optional' and requires exactly one WordPress plugin for Easy Digital Downloads or WooCommerce, review screening is limited to 1–3★ reviews, and Attack Mode may be 'active, or suggested after a burst, with its price'. The '(capability: company.settings_own)' tag discloses the authorization requirement, which is useful even if slightly surprising for a read-only status call.

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?

All content is front-loaded in a single sentence, but that sentence is a long comma-delimited enumeration with nested parentheticals that is hard to scan. The information earns its place, but its density and lack of structure (no separation between what is returned and how it behaves) reduce readability.

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 read-only aggregate status tool with one optional parameter and no output schema, the description provides an adequate map of what the response covers, including edge behaviors like the 1–3★ review filter and conditional Attack Mode. A field-level return structure is absent, but the topical enumeration is sufficient for an agent to decide whether calling it answers its question.

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?

There is a single optional parameter with 100% schema description coverage, and the schema already explains the Trustpilot domain format and the multi-company condition. The description adds nothing about the company parameter, so the baseline of 3 is appropriate, though the impact is minimal given only one well-documented parameter.

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 names the resource precisely ('Your onboarding checklist') and enumerates its constituent parts: account activation, team membership, billing state, Trustpilot delegated access, evidence integration, business profile, review coverage, and Attack Mode. This distinguishes it from per-topic siblings like list_team or get_business_profile_questions by making clear it is an aggregate view, though it never states the verb explicitly ('retrieve') or that it returns a consolidated status object.

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?

The framing 'Your onboarding checklist' implies the use case (checking overall setup progress), but there is no explicit when-to-use guidance and no sibling is named as an alternative or complement. An agent must infer that this is a one-call summary that supersedes calling list_team, get_business_profile_questions, and similar tools individually.

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