tomticket_link_customer_department

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

With no annotations provided, the description carries the full burden and does contribute one meaningful behavioral signal: the front-loaded warning 'ATENCAO: altera producao' (ATTENTION: alters production), which tells the agent this is a production-mutating call and should be treated with care. However, it is generic — it does not say what the alteration entails, whether existing associations are replaced, whether the operation is reversible via unlink, or what the response looks like.

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 extremely brief and properly front-loads the production warning before the action statement. However, the main clause merely restates the tool name in Portuguese, and the brevity comes at the expense of usage and behavioral detail that would have fit naturally in the same space. It is short, but under-specification rather than disciplined conciseness.

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 simple flat 3-parameter tool with fully documented params and no output schema, this is minimally adequate: an agent knows the action and the required inputs. But it is incomplete in important ways — the meaning of 'enviado como configuration' for department_id is unclear, there is no statement about whether the link replaces existing associations or how success/failure is returned, and the mutation behavior beyond the generic warning is unexplored.

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 the baseline is 3. The tool description adds nothing about parameters beyond the schema, which already documents customer_id (internal ID or email), department_id (department identifier sent as configuration), and customer_type_id (I vs E, default I). The description neither compensates for gaps nor introduces contradictions, so the baseline 3 stands.

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 a specific verb and resource: 'Vincula um departamento ao cliente' (links a department to the customer). The action is unambiguous and the link verb inherently separates it from the sibling tomticket_unlink_customer_department. However, the core clause is essentially a translation of the tool name, adding little new semantic information, and it does not explicitly differentiate from siblings.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention the counterpart unlink tool (tomticket_unlink_customer_department), does not state when linking is appropriate, and provides no exclusions, prerequisites, or context such as needing a department from tomticket_list_departments first. Usage is only implied by the action phrase.

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