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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, setting a lower bar. The description adds value by disclosing the actual return payload (services with aliases and starting price, neighborhoods, rating with source, recent reviews, agent_readiness index), which goes beyond the structured fields.

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?

A single dense sentence, front-loaded with the core identity ('Perfil completo de um profissional') followed by the input source and content list. No wasted sentences, though the content enumeration is heavy.

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?

No output schema exists, so the description bears the burden of describing returns — and it enumerates the key fields well. Combined with annotations covering the safety profile, this is nearly complete; only edge behavior (e.g., what happens on an unknown slug) is unstated.

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 coverage is 0% for the single 'slug' parameter, so the description must carry meaning. It does identify the value's origin (comes from find_providers), which is genuinely useful, but adds no format or constraint details (e.g., URL-format slug, case sensitivity).

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?

States a specific verb+resource: the complete profile of a professional. It names the sibling that produces the required input (find_providers) and enumerates the profile contents, so an agent can distinguish it from list/search siblings.

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?

Usage is implied through the parenthetical '(slug vindo de find_providers)', which establishes the intended flow of find_providers → get_provider. There is no explicit statement of when not to use it or how it compares to compare_providers or estimate_price.

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