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

The description adds useful context beyond annotations: it explains that the tool writes and returns idTarefaJob for later updates, and warns that write field names differ from read field names returned by iclips_projects_extract. This kind of behavioral nuance is not captured by readOnlyHint or destructiveHint.

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-organized with action blocks, optionals, return-value notes, and a field-mapping warning. It is compact given the amount of detail, though it is slightly redundant by documenting both create and update in a create-named tool.

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?

It covers required fields, optional fields, date/priority constraints, the returned ID, and bulk support. Still, it omits how the data payload should actually be serialized for the string data parameter, leaves account unexplained, and does not fully resolve whether update is really available in this tool. With no output schema, response details are also missing.

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?

With 0% schema coverage, the description compensates by listing data fields like titulo, descricao, inicioDate, fimDate, prioridade, and ordemExibicao with constraints. However, there is a notable mismatch: the schema types data as a string but the description treats it as an object with fields, and the account parameter is not explained.

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 states it creates or updates a manual task inside an existing iClips job, naming the verb and resource clearly. However, it covers both create and update actions while the tool name and 'Flattened action: create' signal create-only, creating some ambiguity with sibling iclips_job_tasks_write_update.

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?

It gives explicit requirements for each action: create requires job_id and data.titulo, update requires task_id, and optional fields are listed. It does not mention the sibling alternative or specify when to prefer this tool over iclips_job_tasks_write_update, but the per-action guidance is concrete and actionable.

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