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

No annotations are provided, so the description carries the full burden. It mentions the action ('Disable') and a return value, but lacks critical behavioral details: whether this is a destructive change, if it requires specific permissions, potential side effects (e.g., downtime, SSL certificate removal), or error conditions. The description is minimal and doesn't compensate for the missing annotations.

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 well-structured with clear sections (purpose, args, returns) and uses minimal sentences. It's front-loaded with the core action and avoids unnecessary details, though it could be slightly more concise by integrating the parameter explanation into a single sentence.

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 complexity (a mutation tool disabling a security feature), lack of annotations, and no output schema, the description is incomplete. It doesn't address safety, permissions, or operational impact, which are crucial for an agent to use this tool correctly in context. The return value is mentioned but not detailed, and behavioral transparency is lacking.

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%, so the description must compensate. It adds value by explaining the 'load_balancer_id' parameter with examples (e.g., 'web-lb', 'api-load-balancer', or UUID), which clarifies acceptable formats beyond the schema's 'type: string'. However, it doesn't cover other potential nuances like validation rules or constraints, leaving some gaps.

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 verb ('Disable') and resource ('Auto SSL for a load balancer'), making the purpose specific and understandable. However, it doesn't distinguish this tool from potential siblings like 'enable_auto_ssl' or 'configure_auto_ssl' (which aren't listed but could exist conceptually), so it's not fully differentiated.

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 no guidance on when to use this tool versus alternatives, prerequisites, or exclusions. Given the sibling tools list includes many configuration and management tools (e.g., 'configure_basic_web_lb', 'update'), there's no indication of how this fits into broader workflows or when it's appropriate.

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