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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is covered. The description adds meaningful context beyond the annotations: the tool is free, needs no API key, returns a score out of 100, and names the two biggest gaps, though it does not discuss edge cases such as omitted parameters or output formatting.

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 description is front-loaded with the core purpose and result, then efficiently lists the eight dimensions and supporting details such as cost, authentication, and documentation. There is no redundant or filler text.

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?

Given eight optional boolean parameters, no output schema, and no required parameters, the description supplies enough context for an agent to invoke the tool correctly. It explains the input dimensions, the scoring outcome, and the additional gap analysis without needing an output schema.

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 100%, and each boolean parameter already includes a detailed explanation with its point value. The description lists the same eight categories but does not add meaning beyond what the schema provides, so the baseline 3 is appropriate.

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 states a specific verb and resource: it scores AI readiness for a small business, out of 100, from eight yes/no inputs, and returns the two biggest gaps. This clearly distinguishes it from sibling calculators such as calculate_ai_savings, calculate_ai_time_saved, and score_answer_readiness.

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 usage context is implied by describing a readiness assessment for a small business, but there is no explicit guidance on when to choose this tool over sibling tools or when not to use it. It also does not mention prerequisites beyond being free and requiring no key.

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