zabbix_action_update

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

No annotations are provided, and the description lacks any behavioral details such as side effects, permissions, or expected outcomes. The single-line description adds no transparency beyond the method name.

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 the description is short, it is under-specified rather than concise. It provides no substantive information, making it insufficient for an agent to understand the tool's purpose.

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 lack of annotations, an output schema (though present but mentioned), and many sibling tools, the description is completely inadequate. It does not explain how to use the tool or what it returns.

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 a generic anyOf (object or null) and 0% schema description coverage. The description offers no explanation of what should be passed, failing to add meaning 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?

Description 'Zabbix API action.update method' merely restates the tool name without specifying what an action is or what updating entails. It fails to distinguish from siblings like zabbix_action_create or zabbix_action_get.

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 on when to use this tool versus alternatives. There are siblings such as zabbix_action_create, zabbix_action_delete, and zabbix_action_exists, but the description provides no context for selecting this tool.

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