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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds payment model and data handling (pre-paid credits, LGPD), which is useful, but doesn't disclose rate limits, response format, or potential failures. No contradiction.

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 a single paragraph that is reasonably concise but packs multiple clauses. It front-loads the main purpose but mixes in legal and payment details. Overall, it's adequately brief but not optimally structured for quick scanning.

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?

With only one parameter, no output schema, and no nested objects, the complexity is moderate. The description includes key aspects (official source, payment, data privacy) but lacks specifics on input format and expected output. Given the simplicity, a 3 is reasonable.

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 only parameter 'inscricao' is documented only as a string in the schema, with 0% description coverage. The description doesn't explain what 'inscricao' means (likely registration number), nor its format (e.g., digits only, length). Since the description carries the burden for this parameter but omits details, the score is low.

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 states the tool consults dental council registration records from an official Brazilian source, using a specific verb ('consultar') and resource ('cadastro'). It distinguishes from sibling tools by mentioning the specific council (CRO-CE), though it doesn't explicitly name alternatives.

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 description implies when to use (when needing official dental registration data) but lacks explicit guidance on when not to use or alternatives. It mentions payment and pre-paid credits, which is useful context, but doesn't specify scenarios where other tools might be better.

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