cloud_update_primary_ip

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

No annotations are present, and the description only says 'Update,' implying a mutation. It does not disclose side effects (e.g., whether changes affect active assignments, if updates are reversible, or any required permissions). The behavioral impact is opaque.

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 that front-loads the action and lists the modifiable attributes, containing no extraneous 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?

Despite having an output schema and 4 parameters, the description does not explain the required primary_ip_id, constraints on inputs, or how this tool relates to sibling tools. Key operational details are missing.

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 description names the optional parameters but does not explain their semantics or constraints. The required 'primary_ip_id' is not described at all. With 0% schema coverage, the description adds minimal meaning beyond parameter names.

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 ('Update') and the resource ('primary IP'), and lists the specific attributes that can be modified: name, auto_delete, labels. This distinguishes it from other tools like cloud_create_primary_ip or cloud_assign_primary_ip.

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 alternatives, such as cloud_create_primary_ip for creating a new IP or cloud_assign_primary_ip for assigning an existing one. Prerequisites or context for updating are not mentioned.

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