Get Baidu file metadata

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Get metadata' without revealing whether this is a read-only operation, what metadata fields are returned, how missing/invalid fs_ids are handled, or any rate limits or auth requirements. This is inadequate for an 8-parameter 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?

The description is a single, concise sentence with no redundancy. It effectively communicates the core purpose without wasted words, making it appropriately sized for a tool with minimal context.

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?

Despite the tool having 8 parameters, no output schema, and no annotations, the description provides only a single sentence. It omits essential details such as parameter semantics, return format, behavior for batch requests, and any constraints. This is severely incomplete for a tool of this complexity.

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 7 optional parameters (path, dlink, extra, thumb, detail, deviceId, needmedia) or even the required 'fsids' parameter beyond mentioning 'fs_id values'. The description fails to compensate for the lack of schema documentation.

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 action ('Get metadata') and the resource ('Baidu Netdisk fs_id values'), which distinguishes it from file listing or search tools. However, it does not explicitly distinguish from siblings like baidu_list_files or baidu_search_files, so it lacks explicit differentiation.

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 description provides no guidance on when to use this tool versus alternatives. It does not mention any prerequisites, use cases, or exclusions, leaving the agent without context for tool selection.

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