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

The annotations already mark the tool read-only, and the description adds valuable behavioral context: ascending date order, cursor-forward pagination, and the termination condition on restantes. No contradiction with annotations exists.

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?

Two sentences carry the full operational model: purpose, audience, ordering, and pagination loop. The core behavior is front-loaded and every clause earns its place.

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 has a rich schema, an output schema that presumably defines proximo_cursor and restantes, and read-only annotations. The description fully explains how to start, continue, and terminate pagination, making the tool complete for an agent without further inference.

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 both cursor and limite are already explained in the schema. The description reinforces the cursor usage pattern but does not add substantial new parameter-level meaning beyond what the schema provides.

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 uses a specific verb ('Lista') and resource ('páginas do acervo revisadas'), adds ordering and pagination semantics, and clearly identifies itself as a change feed. This distinguishes it strongly from sibling search/read tools like buscar_paginas and ler_pagina.

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 clear context for when to use the tool ('para quem mantém cópia ou índice do acervo') and an explicit pagination recipe: start with an ISO date or empty, then repeat with proximo_cursor until restantes is 0. It does not explicitly name alternatives or exclusion cases, so it stops short of a 5.

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