Build Baidu auth URL

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

With no annotations provided, the description carries full burden. It accurately states the action (building a URL) but provides no detail on side effects, prerequisites, or behavior like whether it returns the URL as a string or performs network calls. It is not misleading, but lacks depth.

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 sentence that is directly to the point. It contains no wasted words and is well-structured for quick parsing.

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 tool is simple, but with 4 undocumented optional parameters, no output schema, and no annotation, the description alone is insufficient. It lacks information on how the returned URL is used, the meaning of parameters, and how this tool fits into the auth flow.

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 0% and the description does not explain any of the four optional parameters (state, qrcode, display, deviceId). The phrase 'basic,netdisk access' gives scope but no parameter-level meaning, so the agent has no semantic help.

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 uses the specific verb 'Build' and clearly identifies the resource as a 'Baidu OAuth authorization URL' with the scope 'basic,netdisk access'. It communicates the core function effectively, but does not explicitly distinguish it from the sibling tool baidu_auth_qrcode_url.

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 on when to use this tool versus alternatives like baidu_auth_qrcode_url or baidu_auth_exchange_code. No prerequisites, exclusions, or alternative conditions are mentioned.

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