cloud_create_load_balancer

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

No annotations are provided, so the description must disclose behavioral traits. It only states 'Create a load balancer,' implying mutation, but does not mention idempotency, permissions, side effects, or what happens upon duplicate calls.

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 very short (two sentences) and front-loads the purpose. It is concise, though additional details would improve completeness without harming conciseness.

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 the presence of an output schema, the description lacks context about prerequisites (e.g., network must exist), return value semantics, or error handling. For a complex tool with 10 parameters, this is insufficient.

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%, yet the description only addresses the location/network_zone constraint. It fails to explain the meaning of other parameters like algorithm, services, targets, or labels, leaving the agent without sufficient 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?

The description clearly states 'Create a load balancer,' which is a specific verb and resource. It distinguishes from sibling tools like cloud_update_load_balancer due to the verb, but does not explicitly mention that this is for initial creation only.

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 includes a key usage guideline: 'Either location or network_zone is required.' However, it does not provide guidance on when to use this tool versus alternatives like cloud_add_lb_service or cloud_update_load_balancer.

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