Build Baidu QR login

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

With no annotations, the description carries the full burden. It indicates the tool constructs outputs (URL, terminal QR, PNG data URL) rather than performing side effects, but it does not disclose prerequisites, potential network calls, or the nature of the terminal QR format. Minimal but non-contradictory transparency.

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, front-loaded sentence that immediately communicates the core function without filler. Every word adds value.

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?

No output schema or annotations exist, and the description is too terse to fully specify behavior. It does not describe the return structure (how the URL, terminal QR, and PNG data URL are returned) or how parameters affect the output, making it incomplete for an agent.

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 mention the parameters `state` or `deviceId`. The agent receives no explanation of their purpose or format, leaving the invocation ambiguous.

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 clearly states the tool's function with the specific verb 'Build' and identifies the resource: a QR-code Baidu OAuth URL, plus terminal QR and PNG data URL. This distinguishes it from sibling tools like baidu_auth_qrcode_url, which likely only returns a 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?

No usage guidance is provided. The description does not explain when to use this tool over alternatives like baidu_auth_url or baidu_auth_qrcode_url, nor does it mention its place in the OAuth flow.

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