zabbix_valuemap_update

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

With no annotations, the description must disclose behavioral traits, but it only states it is an 'update method' without detailing side effects, required permissions, idempotency, or any constraints. The agent cannot infer important behaviors.

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 it fails to add value; it is under-specified rather than concise. Important information is omitted, so brevity is not helpful.

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 the Zabbix API and the presence of many sibling tools, the description is grossly inadequate. It does not explain what a valuemap is, what the update operation entails, expected output, or how to differentiate from similar tools. The agent cannot effectively use this tool based solely on the description.

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 single parameter 'params' is a generic object with no description in the schema (0% coverage). The description adds no meaning about what fields or structure are expected, leaving the agent with no guidance on how to populate the parameter.

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 valuemap.update method' essentially restates the tool name and verb, providing no additional context about what valuemap.update does or how it differs from related tools like valuemap_create or valuemap_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 is provided on when to use this tool over alternatives, such as when to update versus create or get a valuemap. There are no usage examples or contextual hints.

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