zabbix_user_update

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

No annotations are provided, and the description does not disclose any behavioral traits such as required authentication, side effects, idempotency, or error conditions. The description carries full responsibility but fails to inform.

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 short (one sentence) but omits essential information. It is under-specified rather than concise, as every sentence should add value.

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?

Given the complexity of updating a Zabbix user (many possible fields) and the lack of schema descriptions, the description is completely inadequate. The existence of an output schema does not compensate for the missing input guidance.

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 input schema has a single parameter 'params' with no description, and schema description coverage is 0%. The description adds no meaning to the parameters, leaving the agent with no insight into what the params object should contain.

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 'Zabbix API user.update method' simply restates the tool name with minor rephrasing. It indicates updating a user but lacks specifics about what can be updated or the scope of the operation.

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 guidance is provided on when to use this tool versus alternatives like zabbix_user_create, zabbix_user_get, or zabbix_user_delete. There is no mention of prerequisites or context of use.

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