hostgroup_create

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

Annotations declare readOnlyHint=false (write operation) and destructiveHint=false (non-destructive). The description adds that host groups are containers and their purpose, but does not elaborate on behavioral traits like idempotency (annotation idempotentHint=false), required permissions, or potential side effects beyond creation. The description's value is moderate given annotation coverage.

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 two sentences long, front-loaded with the primary action. Every sentence adds value: the first defines the operation, the second provides conceptual context. No wasted words.

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's simplicity (one required parameter, output schema exists), the description adequately explains the purpose and role of host groups. It lacks explicit usage guidelines but is otherwise complete for a straightforward creation tool.

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 covers 100% of parameters (only 'name') with a description 'Name of the host group.' The tool description does not add extra semantic detail about the parameter beyond what the schema provides. Baseline 3 is appropriate due to full schema coverage.

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 action: 'Create a new host group in Zabbix.' It distinguishes from sibling tools (e.g., hostgroup_delete, hostgroup_get, hostgroup_update) by focusing on creation. The additional explanation of host groups as containers adds context without ambiguity.

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 explains when host groups are useful (for permissions, templates, maintenance) but does not explicitly state when to use this tool over alternatives or provide exclusion criteria. No direct comparison with sibling tools, leaving usage context implied rather than explicit.

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