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

Annotations declare readOnlyHint=false, destructiveHint=true, idempotentHint=false, and openWorldHint=false, but the description adds no behavioral context beyond the basic purpose. It does not explain what may be overwritten or destroyed, whether existing generated SDKs are replaced, where output is written, or what permissions are needed, which is especially important given destructiveHint=true.

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 front-loaded sentence with no filler. However, it is arguably too terse for a destructive SDK generation tool, so it earns credit for concision but not top marks.

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?

There is no output schema, and the description does not explain return values, generated artifact locations, or the effect of the destructive flag. Combined with no usage guidance and a destructive annotation, the description is not complete enough for an agent to invoke this tool confidently.

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 100%, and each parameter is documented with its default, so the schema already carries the parameter semantics. The description does not add any meaning about languages, documentation inclusion, or force rebuilding beyond what the schema provides, making baseline 3 appropriate.

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 a specific verb and resource: generate client SDKs for the domain's schemas. It is clearly distinct from sibling tools like sdk_download, sdk_list, and sdk_status in purpose, though it does not explicitly name alternatives or clarify what "domain's schemas" means in context.

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?

It gives no guidance on when to use this tool versus sdk_download, sdk_list, or sdk_status, nor does it mention prerequisites, expected input state, or when generation should be preferred over downloading an existing SDK. The agent must infer usage entirely from the tool name and one sentence.

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