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

Annotations already declare readOnlyHint=false and destructiveHint=false, but the description adds critical context: it warns that this alters PRODUCTION data and that Bsoft has no homologation environment. This is valuable beyond annotations. It also notes bulk support for batched execution, which is behavioral context not present in annotations.

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 concise and front-loaded with the core purpose. It uses bullet-point-like formatting and a warning emoji to highlight the production risk. The 'Flattened action: create' line is redundant but clarifies the action, and the bulk support note is brief. No excessive verbosity, but it could be slightly tighter by removing the redundant flattened action note.

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 WRITE tool with 7 parameters, 0% schema coverage, no output schema, and no annotations beyond readOnly/destructive hints, the description covers the essential operational details: required parameters, the production warning, the need for id/parent_id, and bulk support. However, it lacks details on return format, error handling, or validation constraints that an agent might need to anticipate failure modes. Given the tool's complexity and risk, a 4 is appropriate.

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 coverage is 0% (no parameter descriptions in the schema), but the description lists key parameters in prose: 'resource', 'action', 'body', 'id', 'parent_id', and mentions the 'lotes' endpoint for lists. This partially compensates for the schema's lack of descriptions. However, the description does not explain the format of 'body' (e.g., JSON structure) or the purpose of 'ids' and 'parent_ids' beyond bulk support, leaving some ambiguity.

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 'Ordem de Serviço no Bsoft TMS (escrita: cria/atualiza/remove)' and lists the writable resources, distinguishing it from read-only siblings and other write tools. However, the opening sentence is a bit general (covers create/update/remove) without emphasizing that this tool is specifically for create operations, which is clarified later by 'Flattened action: create'.

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 explicit guidance on using 'resource', 'action', and 'body', and states that update/patch/delete require 'id' and nested resources require 'parent_id'. It also mentions the create_lote endpoint for lists, which helps differentiate this create tool from sibling write tools. However, it does not explicitly say when to use this tool vs alternatives like the dedicated create_lote sibling.

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