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

The warning about production data and lack of homologation adds valuable context beyond the annotations. However, it inconsistently mentions multiple actions (update/patch/delete) and 'create_lote', which could mislead about actual behavior. It doesn't describe return values or side effects beyond the generic 'altera dados'.

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 verbose and redundant. It lists resources, mentions actions not relevant to the tool, and has an odd '[Flattened action: update]' line. The flow is not clear, and the production warning interrupts the instruction flow. Could be condensed into a focused, single-purpose description.

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 an update tool with 7 parameters and no output schema, the description lacks critical details: what the response looks like, required vs optional parameters per action, error behavior, and how `action` fits (since it's not in the schema). The bulk support mention is vague and doesn't clarify batching mechanics.

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 must compensate but only partially does. It explains that `id` is required for update, `parent_id` for nested resources, and bulk uses `ids`, but it fails to explain `account`, `body` details, and introduces `action` which is not in the schema. This is confusing and incomplete.

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 is ambiguous: it says 'cria/atualiza/remove' (create/update/remove) but the tool name is 'write_update' and sibling tools exist for create/delete/patch. It doesn't clearly state that this tool specifically updates OS records, and the mention of 'create_lote' and multiple actions muddies the purpose.

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?

No explicit when-to-use guidance or distinction from sibling tools (e.g., 'Use this instead of bsoft_os_write_patch to update OS'). It mentions general requirements like id and parent_id but does not clarify when this tool is the right choice over create/delete/patch tools.

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