vibemk_create_host_hostgroup_rule

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

No annotations are provided, so the description must carry the transparency burden. It states the intended outcome but does not disclose side effects such as activation requirements, duplicate handling, or whether existing rules are overwritten.

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 concise sentence with a clear action and purpose. The emoji is decorative but does not harm clarity.

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?

The description gives enough high-level context for a straightforward call, but the nested host_conditions object is under-specified and no output schema or error behavior is mentioned. Agents may need additional examples or details to construct valid conditions.

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 coverage is 100% and each parameter has a description. The description adds high-level context but does not significantly expand on the schema-provided parameter meanings, especially for nested condition structures.

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 host group rule') and the purpose ('Assign hosts to host groups based on conditions'). It distinguishes this tool from sibling tools like create_host_group and create_rule.

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 implies usage when assigning hosts to host groups via a rule, but it does not explicitly mention alternatives, when-not-to-use, or prerequisites. No sibling tool is referenced for comparison.

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