update_department

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

Includes '[DESTRUCTIVE]' hint and clarifies partial updates, but with no annotations, the description should disclose more about side effects, required permissions, or whether the update is reversible. The coverage is adequate but not thorough.

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?

Three brief sentences with no redundancy. The destructive hint is front-loaded, and each sentence serves a clear purpose: action, prerequisite, and behavior.

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?

Lacks information about return values or success/error responses, which is important since no output schema is provided. Also, it does not mention whether updates are synchronous. Could be more complete for a mutation operation.

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?

The description adds value beyond the 100% schema coverage by explaining the partial update behavior and pre-requisite step for the 'id' parameter. This helps the agent understand the intended usage.

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 the verb 'Updates', the resource '3CX department', and the identifier method 'by its numeric Id'. It also notes to obtain the Id from list_departments, distinguishing it from create_department and other 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?

Provides explicit instruction to get the Id from list_departments first and notes that only provided fields are changed. However, it does not contrast with alternative tools like update_user or mention when not to use this tool.

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