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

Beyond the annotations, it discloses the temporary nature, precise quota of 3 requests, 30-minute expiry, capped shared budget, no-account requirement, and the need to share a signup link. This is rich behavioral context for a mutating, non-destructive tool.

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?

Four sentences, each adding distinct value: key constraints, target use case, output usage, and follow-up action. No filler or repetition of the title.

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?

The description covers selection, invocation, and follow-up, including the exact quota/expiry and where to pass the returned key. The only minor gap is that it instructs the agent to share a signup link without stating where that link comes from or its URL.

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?

With zero parameters the schema is empty, but the description explains what to do with the result: pass the returned key as the api_key argument to audio tools. That adds useful semantic guidance beyond the empty schema, meeting the zero-parameter baseline.

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 pins down exactly what the tool does: mints a temporary, account-less oruk API key with a 3-request/30-minute scope. This clearly distinguishes it from the sibling audio-processing and account-checking tools.

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 names a concrete trigger: use when no Authorization header is configured and the user wants an immediate transcription or tone-analysis trial. It lacks an explicit 'when not to use' statement, but the trigger condition and follow-up instructions are clear.

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