Renomear item do Estúdio

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

Annotations already declare readOnlyHint=false, destructiveHint=false and openWorldHint=true, so the safety profile is partly covered. The description adds nothing on top: it does not say whether the rename is reversible, what happens if the 'item' string matches multiple items, or whether generation state is affected.

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 short sentence with no waste, so it is concise, but the brevity is under-specification rather than efficiency — there is nothing front-loaded beyond the bare action.

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?

This is a mutation tool with three required parameters, no output schema, and an open-world hint, yet the description never explains matching/ambiguity resolution or what the caller gets back. For a rename operation on generated Studio artifacts, an agent needs more than one sentence.

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 67%, and the one undocumented parameter is the most important new value: novo_titulo (with a maxLength of 300) has no description anywhere. The description also adds no semantics for 'item', which per the schema accepts a partial title or an id and could match ambiguously.

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 ('Muda o título') plus a scoped resource ('item do Estúdio'), which distinguishes it from notebook_renomear and notebook_fonte_renomear that target notebooks and sources rather than Studio items. It is clear what is changed but never says what a 'Studio item' is beyond the name.

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 versus notebook_renomear, notebook_fonte_renomear, or notebook_estudio. Nothing states prerequisites (e.g., the item must already exist or be finished generating) and no exclusions are given.

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