update_host_group

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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses nothing about permissions required, whether the change is reversible, what happens to hosts currently in the group, or what the response contains. For a mutation tool this is a complete transparency gap.

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 single phrase is short, but this is under-specification rather than conciseness; there is no front-loaded statement of effect, target, or constraints for the agent to act on.

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 no annotations, no output schema, 0% schema description coverage, and two ambiguous required parameters, the definition omits essentially everything an agent needs to invoke this mutation correctly.

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 0% and the two required numeric parameters (id, groupID) are semantically ambiguous — it is not stated which identifies the group being modified and which identifies the new parent/group value. The description supplies none of this missing context.

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?

"Update host group" merely restates the tool name with no additional information: no statement of what aspects of the group are updated, no scope, and no differentiation from the sibling update_host_group_by_id, which appears to do the same thing.

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 when-to-use or when-not-to-use guidance, no prerequisites, and no indication of how this differs from update_host_group_by_id. An agent has no basis for choosing between the two beyond guessing.

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