Actualizar rol

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that it updates a role, but does not explain partial vs. full replacement, required permissions, reversibility, or side effects on associated data. This is a significant gap for a mutation tool.

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 concise sentence with no wasted words. It front-loads the action and target. However, its brevity is also a weakness, as it omits essential details, but that is a content issue rather than a structure issue.

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?

Given the tool's complexity (4 parameters, nested object, no output schema, no annotations), the description is woefully incomplete. It does not mention return values, behavior of optional fields, or any constraints. An agent cannot reliably invoke this tool correctly based on this description.

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 only 25% (only 'id' has a description), so the description must compensate for the other parameters. It mentions 'por id' but offers no meaning for 'name', 'extra', or 'description'. The agent gets almost no help understanding these fields beyond their types.

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 'Actualiza los datos de un rol por id' clearly states a specific action (update) on a specific resource (role) identified by id. This distinguishes it from siblings like create_role, delete_role, and list_roles. The purpose is unambiguous.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or any comparison with related role operations. The agent is left to infer usage from the tool name and schema.

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