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

Annotations already establish the read-only, idempotent, non-destructive nature. The description adds behavioral value by specifying that results are the most recently imported transactions and by disclosing pagination behavior via page/per_page with default 50 and max 100. No contradiction with annotations.

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?

Three short sentences each carry meaningful information: scope, intended use case, and pagination rule. There is no filler or redundancy, and the most important scoping information is front-loaded.

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 simple read-only paginated list, the description provides the core selection criteria, a concrete use case, and pagination details. With no output schema, slightly more detail about the returned transaction fields would help, but the essential invocation context is present.

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?

With 0% schema description coverage, the description partially compensates by explaining page/per_page and their default/max values. However, the schema also includes a 'limit' parameter whose role is never clarified, leaving a gap in parameter understanding.

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 identifies the resource — most recently imported transactions via Open Finance — and its scope (connected accounts/cards). It is distinguishable from sibling transaction tools through the 'via Open Finance' and 'recém-importados' framing, though it does not explicitly name alternatives or state what it is not.

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 explicitly says 'Use para lançamentos novos/recém-importados', giving a direct trigger condition for when the agent should select this tool. It does not contrast with organizze_list_transactions or organizze_search_transactions, so exclusion guidance is absent, but the intended use case is clear.

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