Baidu Download

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

With no annotations, the description carries the full burden. It helpfully flags 写操作 (write), but omits auth/profile requirements, whether the download is asynchronous (likely, given baidu_task_list/baidu_task_info siblings), rate limits, and how the conflict default ('rename') applies.

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?

A single compact sentence with the write-operation caveat included. Efficiently front-loaded, though at the cost of omitting important usage 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?

An output schema exists so return values need not be explained, but for a 7-parameter download tool with zero annotations the definition says nothing about async task semantics, login/session requirements, or failure behavior — significant gaps for an agent to invoke it correctly.

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 86%, so the schema already documents host, port, scheme, profile, fsids and target_path. The description adds no parameter detail beyond contextualizing the source (网盘) and destination (NAS), so the baseline 3 applies.

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?

States a specific verb (下载/download) and both endpoints of the movement (从网盘 to NAS), plus that it is a write operation. It is clear what the tool does, though it does not name the contrasting siblings such as baidu_upload (reverse direction) or file_download_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?

Only says what it does, not when to choose it over baidu_upload, file_download_url, or the baidu_task_* family. No prerequisites (login/profile) or exclusions are given.

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