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

Annotations already declare readOnlyHint=true, idempotentHint=true and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds only that the content is "public" (no auth implied) and is a service description rather than client data; with zero parameters there is little further behavior to disclose.

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?

Two sentences, no redundancy, and the purpose is front-loaded ahead of the routing guidance. Every clause carries information about either what is returned or when to call it.

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 no-param, read-only lookup with no output schema, this is nearly complete: an agent knows what the tool is, who it is for, and when to use it. It does not hint at what fields the returned details contain, which is a minor gap given no output schema exists to cover that.

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?

The tool takes zero parameters and the schema is empty, so there is nothing for the description to disambiguate. Baseline of 4 applies for a no-argument tool.

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?

Specific verb ("Returns") plus a concrete resource ("white label and outsourced compliance documentation service") and a named audience (consultancies, MSPs, professional advisers). It is clear, but it does not explicitly distinguish itself from the nearby get_partner_programme sibling, which an agent could plausibly confuse with a white-label offering.

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 second sentence gives a genuine selection condition: use it when a firm wants fulfilment under its own brand rather than referring the end client to Clausely. That is a real when-to-use rule, though no sibling tool is named as the alternative for the referral case.

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