provision_api_key

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

No annotations provided, so description carries full burden. It states that instructions and URL are returned, but does not disclose if this operation is read-only, has side effects, requires authentication, or what happens if the service does not exist.

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?

Single sentence clearly conveys purpose. No filler or redundancy, but could be slightly more informative about the output.

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 simplicity (1 param, no output schema, no annotations), the description is adequate. However, it lacks details on the format of instructions/URL and error handling, and does not leverage context of sibling tools to clarify usage.

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?

Only one parameter 'service' with schema description 'Service name'. Schema description coverage is 100%, so the description adds no additional meaning beyond what the schema already provides. Baseline 3 is 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?

Description explicitly states the tool provides step-by-step instructions and a signup URL for acquiring an API key. The verb 'get' and resource 'instructions/URL' are specific, and the tool is clearly distinguished from siblings like get_api_key (which retrieves existing keys) and store_api_key (which stores keys).

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?

No explicit guidance on when to use this tool vs alternatives. The description does not mention when not to use it, prerequisites, or mention siblings like list_services or check_api_key.

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