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

Annotations only declare non-read-only, non-destructive, non-idempotent. The description goes well beyond: all-or-nothing semantics ('se um item for recusado, NENHUM é gravado'), the response naming the offending item and reason, duplicate-name rejection returning the existing id, that deactivation hides from lists but preserves history, and that writes land in upCampo. That is the behavioral detail the annotations cannot carry.

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?

Four dense sentences, front-loaded with the resource scope and then the batch/write semantics. Every sentence earns its place, though the stray blank line and the layering of batch rules, duplicate handling and confirmation flow make it slightly heavier than needed.

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?

An output schema exists, so return-shape explanation is unnecessary, and the description still notes the response identifies the rejected item and reason. Given the batch, confirm-before-write and deactivation semantics, nothing an agent needs to invoke this correctly is 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?

Schema description coverage is 100%, so `id`, `codigo`, `desativar`, `descricao` and `fazenda` are already documented per-field. The description consolidates the id/no-id/desativar interaction model but adds little syntax beyond the schema; the duplicate-name rule it contributes is behavioral rather than parametric. Baseline 3 is appropriate.

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?

States a specific verb and resource (cadastrar local de estoque) and names the concrete scope: depósito, galpão, barracão. It also rules out silo and posto de abastecimento, which are handled by the portal, so an agent can distinguish this from siblings like cadastrar_talhao or consultar_estoque without opening a schema.

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?

Explicitly tells the agent to batch everything the user dictated in one call (up to 50), and states the three operating modes: no `id` inserts, `id` updates only the given fields, `id`+`desativar` deactivates. It adds a workflow instruction (show the list and confirm before calling) and an exclusion (silo/posto via portal), leaving little to inference.

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