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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds real behavioral context beyond that: it does not initiate AI analysis and reuses the documental access rather than triggering a new analysis on query. These are genuine additions, though they are terse and somewhat cryptic.

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?

It is front-loaded with the content inventory, and most clauses carry information. Some phrasing is compressed and opaque ('Dados parciais informam cobertura'), which reduces clarity rather than length, keeping it from a clean 4.

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 read tool with 8 parameters, complex multi-code authentication and no output schema, the description covers the behavioral essentials (AI not triggered, access reuse, export gating) but says nothing about the shape or pagination of returned facts beyond naming content categories. Adequate but with visible gaps.

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%, so all 8 parameters are already documented in the schema (including the elaborate acesso_codigo and agent_pass semantics). The description only restates that acesso_codigo matches the leitura, adding no syntax or format detail beyond the schema, so the baseline 3 applies.

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 enumerates the resource contents (itens, exigências, atestados, prazos, obrigações with conditions/exceptions/excerpts), which conveys that this returns a structured dossier, but it never states an explicit action verb. The reader must infer retrieval from the name and content list rather than being told outright.

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?

It gives a useful access condition (reuses the same acesso_codigo as documento_leitura) and a gating rule (export requires the completed version), implying when the tool is usable. However, it never explicitly contrasts when to use this versus documento_leitura or documento, leaving the choice to inference.

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