zabbix_trigger_exists

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

No annotations are present, and the description fails to disclose any behavioral traits such as return type (likely boolean), authentication requirements, or side effects. The description carries the full burden but provides nothing.

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 (one short sentence), but it is under-specified rather than usefully concise. It fails to convey essential information, so it does not earn high marks for 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?

Given a vague schema and no annotations, the description is completely inadequate. It does not explain the tool's purpose, parameters, or output, leaving the agent unable to use it correctly.

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 one parameter 'params' with no description and 0% schema description coverage. The description does not explain what the params object should contain or how to use it, adding no value beyond the schema.

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 simply states 'Zabbix API trigger.exists method', which is a tautology of the tool name. It does not explain that the tool checks for the existence of a trigger, nor does it differentiate from sibling tools like trigger_get or trigger_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?

No guidance is provided on when to use this tool versus alternatives such as zabbix_trigger_get or zabbix_trigger_exists. The agent receives no context about appropriate use cases.

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