zabbix_hostgroup_update

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

The description indicates an update operation, implying mutation, but provides no details on behavioral aspects such as idempotency, merging vs replacement, permissions required, or side effects. With no annotations, the description should compensate but does not.

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 (one sentence) but lacks structure and fails to provide useful information. It is not concise in a helpful sense; it omits critical details.

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 is a mutation with a high-risk generic schema, the description is woefully incomplete. It does not explain return values, required fields, or how to specify which hostgroup to update.

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 contains a single generic 'params' object with 0% schema coverage. The description does not explain what properties this object should contain (e.g., hostgroupid, name), leaving the agent unable to construct a valid call.

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 states 'Zabbix API hostgroup.update method', which identifies the resource (hostgroup) and action (update). It is clear but lacks specificity; it does not distinguish from sibling tools like zabbix_hostgroup_create or zabbix_hostgroup_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?

No guidance is provided on when to use this tool versus its siblings. There is no mention of prerequisites, appropriate contexts, or scenarios where alternatives should be preferred.

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