createCategory

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. 'Criar categoria' discloses nothing about side effects, permissions, validation rules, or return behavior, leaving the agent completely in the dark about the mutation's implications.

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 extremely short, but this is under-specification rather than effective conciseness. It lacks any useful structure or content, failing to earn its place as a meaningful explanation for a tool with three parameters and no annotations.

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 mutation nature, the three parameters, and no annotations, the description is wholly inadequate. Even though an output schema exists, the description does not explain the purpose, usage, or behavioral nuances, making it impossible for an agent to correctly select and invoke this tool without additional context.

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?

The description adds no information about the three parameters (name, color, parent_id). Schema coverage is only 33% (only color has a description), and the description does not compensate for the missing semantics of name or parent_id. The agent must rely solely on names and types, which are insufficient.

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 'Criar categoria' is a Portuguese translation of the tool name 'createCategory', providing no additional specificity beyond restating the name. It is a tautology and does not distinguish the tool's exact scope or behavior from sibling tools.

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 offers no guidance on when to use this tool versus alternatives like updateCategory, deleteCategory, or createAccount. There is no mention of context, prerequisites, or exclusions.

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