zabbix_dservice_update

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

With no annotations, the description carries full burden for behavioral disclosure, but it offers none. It does not state whether the update is partial or full, whether it is idempotent, what side effects occur, or any authorization requirements.

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?

While extremely short, the description is not meaningfully concise; it merely restates the tool name. Important information is missing, so it is under-specified rather than concise.

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?

Despite the existence of an output schema (not provided) and many sibling tool names, the description itself fails to provide sufficient context for an AI agent to use it correctly. The very permissive input schema without explanation leaves the agent without 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?

Schema description coverage is 0%. The description adds no meaning to the single 'params' parameter. The schema allows arbitrary properties, but the description does not clarify expected keys or value types.

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 dservice.update method' clearly indicates it updates a dservice, and the name distinguishes it from siblings like create/delete/get. However, it does not explain what a 'dservice' is, relying on the user's prior knowledge.

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 no guidance on when to use this tool versus alternatives such as zabbix_dservice_create or zabbix_dservice_delete. There is no mention of prerequisites, intended context, or typical workflow.

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