get_transaction

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the read-only nature is covered. The description adds a vague mention of authorization ('autorizado antes de retornar seus dados'), but it's unclear whether this is a prerequisite or a runtime behavior, and it doesn't clarify what happens when authorization fails. This adds minimal value beyond 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?

The description is a single sentence, but it is poorly structured and ambiguous. Brevity without clarity is not conciseness; it reads as an incomplete thought.

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 get-by-ID tool with an output schema present, the description fails to explain what the transaction object contains, how to handle authorization, or any behavioral nuances. The agent is left without essential context for correct invocation.

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% and the description never mentions transaction_id or any parameter details. The agent gets no clue about what the UUID represents or how it is used beyond its name.

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 mentions 'transação' (transaction) and 'retornar seus dados' (return its data), which suggests it retrieves transaction data, but the phrasing is convoluted and fails to clearly state the operation. It doesn't explicitly say 'get a transaction by ID' or distinguish from siblings like list_transactions.

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?

There is no guidance on when to use this tool versus alternatives such as list_transactions or get_account. No context, prerequisites, or conditions are provided.

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