zabbix_create_discovery_rule

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

There are no annotations, so the description carries full burden. It fails to disclose any side effects, prerequisites (e.g., host must exist), permissions, or whether the rule is enabled by default. The single sentence offers zero behavioral insight beyond the action itself.

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 a single sentence with no wasted words, aligning with conciseness. However, it is not front-loaded with key differentiators or usage context. It is efficiently worded but lacks substance for a tool of this complexity.

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?

With 12 parameters, nested objects, no output schema, and no annotations, the description is severely incomplete. It does not explain return values, required versus optional fields, or how to construct valid requests. It only restates the tool's name, leaving the agent to rely solely on the schema.

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 100%, with every parameter having a description. The tool description adds no additional parameter meaning, so the baseline score of 3 applies. It does not clarify relationships between parameters or provide examples 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 clearly states the verb 'Create' and the resource 'Low-Level Discovery (LLD) rule in Zabbix'. This distinguishes it from update/delete/get discovery rule siblings, though it could be more specific about the Zabbix API context.

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 (e.g., zabbix_create_item, zabbix_get_discovery_rules). It simply states the action with no context or exclusions, offering no help for tool selection.

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