cloud_insts_en_portsec

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

With no annotations provided, the description carries full burden. It only states the action but does not disclose side effects, reversibility, required permissions, or behavior if port security is already enabled.

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 structured with 'Args:' and bullet points, but the parameter descriptions for extra_headers, extra_query, extra_body, and timeout are redundant with the schema. The key information on project/region resolution is valuable but could be more concise.

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 7 parameters, 3 required, and no output schema, the description is incomplete. It does not explain what port security is, what the tool returns, error conditions, or the meaning of port_id.

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?

Despite 0% schema coverage, the description adds semantic meaning for project_id and region_id (e.g., resolution rules). However, it does not explain port_id or the optional parameters beyond generic phrases like 'Send extra headers'.

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 starts with 'Enable port security for instance interface', clearly stating the action and resource. It is distinguishable from sibling tools like cloud_insts_dis_portsec which disables port security.

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 provides explicit guidance on how to pass numeric project_id and region_id, including fallback resolution via other tools. However, it does not mention when to use this tool versus alternatives or prerequisites beyond parameter resolution.

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