zabbix_regex_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 side effects, required permissions, or data modifications. It simply labels the method without indicating consequences of invoking it.

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 but lacks substance. It uses minimal wording at the cost of clarity and usefulness, making it under-informative rather than efficiently 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?

Given the tool has no annotations and a single parameter with no description, the one-sentence description is grossly insufficient. It fails to explain the tool's purpose, input format, or output, leaving the agent with virtually no 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 only one parameter ('params') with 0% schema description coverage, yet the description adds no information about what the parameter should contain or represent. The agent receives no help in constructing valid input.

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 regex.update method' only restates the tool name and does not specify what is being updated or the resource involved. It offers no distinction from sibling tools like zabbix_regex_create or zabbix_regex_delete.

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?

There is no guidance on when to use this tool versus alternatives like zabbix_regex_create or zabbix_regex_delete. The description lacks any context about prerequisites or appropriate scenarios.

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