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

With no annotations, the description bears the full burden of behavioral disclosure. It explains the ranking logic but does not disclose pagination behavior, default filters, response format, or access constraints. The fragment 'Understanding plan' hints at some plan-related context but is too vague to be actionable.

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?

The main sentence is concise and front-loaded with the key ranking concept. However, the trailing phrase 'Understanding plan.' is unclear and does not earn its place, reducing overall structural quality.

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?

The tool is simple, but no annotations or output schema exist, and the description leaves important gaps: response contents, default type, pagination semantics, and what 'profiled set' refers to. An agent could invoke it but would not know exactly what result shape to expect.

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 only 25%, so the description needs to compensate. It does map the 'type' enum conceptually to 'Services, tools, or standards' and clarifies the adoption ranking, but it adds nothing about 'page' or 'limit' and leaves the meaning of the metric only partially defined.

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 clearly identifies the resource ('Services, tools, or standards') and the ranking criterion ('how many companies adopt them'), which gives the tool a distinct identity among the many insight-related siblings. It lacks an explicit verb like 'returns' or 'lists', but the intent is still specific and decipherable.

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?

No guidance is given about when to use this tool instead of related ones such as insights_dimensions, find_company_insights, or get_company_insight. There are no exclusions, prerequisites, or alternative routing cues.

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