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. While it states this is a batch addition operation and describes the return structure, it doesn't mention important behavioral aspects: whether this requires specific permissions, if there are rate limits for batch operations, what happens when some tasks fail (partial success handling), or whether the operation is atomic. The return format description is helpful but insufficient 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 well-structured with clear sections for Args and Returns. The Portuguese text is direct and efficient. However, the 'Args' section could be more concise by integrating the batch object explanation into the main description rather than as a separate bullet point.

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 batch mutation tool with no annotations and 0% schema description coverage, the description is moderately complete. It explains the basic operation and return format (which is helpful since there's an output schema), but lacks critical context about permissions, error handling, batch constraints, and differentiation from sibling tools. The presence of an output schema reduces the burden slightly, but important behavioral aspects remain undocumented.

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. It provides the parameter name 'batch' and indicates it's a 'BatchTaskAdd' object containing a task list, which adds meaningful context beyond the bare schema. However, it doesn't explain the structure of individual tasks, validation rules, or constraints on batch size. The description adds some value but doesn't fully compensate for the complete lack of schema descriptions.

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 clearly states the tool's purpose: 'Adiciona múltiplas tarefas em uma única operação' (Adds multiple tasks in a single operation). This is a specific verb+resource combination that distinguishes it from sibling tools like 'get_one_or_more_tasks' or 'list_tasks'. However, it doesn't explicitly differentiate from 'batch_update_tasks' beyond the verb difference.

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. There's no mention of prerequisites, when batch operations are preferred over individual task creation, or how this differs from 'batch_update_tasks'. The agent must infer usage context solely from the tool name and description.

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