rest_generate_routes

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

No annotations are provided, so the description carries the full disclosure burden. It never mentions that the tool requires an api_key (an external authentication signal), whether generated code is returned inline or written to disk, or whether existing files would be overwritten. The phrase 'with validation and error handling' hints at output features but not behavioral side effects.

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?

A single efficient sentence that front-loads the verb and resource and names both frameworks. It is appropriately brief, though the brevity leaves behavioral and usage gaps that a second sentence could have closed.

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?

With no output schema and no annotations, the description should explain what the agent will receive or what side effects occur. It does neither: the return value of the generation, the api_key requirement, and the framework default are all undisclosed, leaving the agent to guess at invocation consequences.

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%, so all four parameters are already documented with names, types, defaults, and an example for endpoints. The description adds no parameter-level detail, but the schema does the heavy lifting, so the baseline 3 applies.

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 ('Generate') and resource ('route handlers'), names both supported frameworks (Express/Fastify), and lists the key features (validation, error handling). This distinguishes it from the many siblings targeting other resources like middleware, scaffolding, or API design.

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 one-sentence description gives no guidance on when to choose this tool over close siblings such as generate_express_api_routes, generate_express_middleware, or http_generate_wrapper. No conditions, exclusions, or alternatives are mentioned.

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