grpcgw_optimize

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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'Optimize' and 'Pro feature'; it does not disclose whether files are modified, whether the operation is destructive or reversible, what checks are performed, or whether an api_key is required for the Pro behavior.

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 one short sentence with the action front-loaded and no wasted words. The parenthetical 'Pro feature' adds relevant context without bloating the text.

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 no annotations, no output schema, and an undocumented api_key parameter, this description is not complete enough for an agent to invoke the tool correctly. It omits expected effects, return behavior, side effects, and the role of api_key.

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 schema documents 'directory' but leaves 'api_key' undescribed, and schema coverage is only 50%. The description adds no meaning for either parameter, so it does not compensate for the undocumented api_key or clarify how it relates to the Pro feature.

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 concrete action ('Optimize') and a specific resource ('gateway performance'), and the grpcgw_ prefix ties it to the gRPC gateway. It is distinguishable from siblings like grpcgw_generate and grpcgw_add_swagger, though it could more explicitly say 'gRPC gateway'.

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?

There is no guidance about when to use this tool versus alternatives, no prerequisites, and no exclusions. The parenthetical 'Pro feature' hints at an entitlement constraint but does not explain when or why an agent should choose this over related grpcgw tools.

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