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

No annotations are provided, so the description carries the full burden, and it discloses nothing: not that this is a mutation, not whether the rename is idempotent or reversible, not whether the name must be unique among diligences, not what permissions are needed, and not what is returned.

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 words is short but this is under-specification rather than conciseness — there is nothing front-loaded because there is nothing to front-load. Nothing in the sentence earns its place beyond restating the name.

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 itself is simple (2 required string params, no nesting, no output schema), which lowers the bar, but with zero annotation coverage and zero schema descriptions the description is the only channel for behavioral and parameter context and it supplies none of it.

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 0%, so the description must compensate, and it does not mention either parameter. Neither 'diligence_id' (which diligence identifier format, where to obtain it) nor 'name' (constraints, length, uniqueness) receives any explanation beyond the bare type.

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?

"Renomeia a diligência" does state a specific verb (rename) and resource (diligence), so the intent is recoverable. But it adds nothing beyond what the tool name 'rename_diligence' already encodes, and it is written in Portuguese while every sibling tool name and the rest of the catalog are in English.

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 alternatives such as create_diligence or get_diligence, and no prerequisites (e.g. must the caller own the diligence?). The single sentence gives context only implicitly through the verb.

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