get_album_songs

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

No annotations are provided, so the description carries the full burden. It discloses the return format (JSON string of the song list) which is useful, but does not mention any side effects, authentication requirements, or error conditions. For a simple read-only getter, this is minimally transparent but not rich.

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 succinct, with a clear title, Args, and Returns sections. It contains no redundant information and is well-structured for quick comprehension.

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?

Given the low complexity (one required parameter, no nested objects) and the presence of an output schema, the description is nearly complete. It covers the input and output format adequately, though it could briefly mention usage context or alternatives to fully round out the picture.

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?

The only parameter album_mid is described in the Args section as '专辑的 MID 标识符' (album's MID identifier), adding clear meaning beyond the schema's bare title. This fully compensates for the 0% schema description coverage, leaving no ambiguity about the parameter's purpose.

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 '获取专辑的歌曲列表' (get album song list), using a specific verb and resource. It distinguishes itself from sibling tools like get_album_detail and get_album_cover by focusing on the song list rather than album details or cover art.

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 implies usage by naming the input (album MID) and output (song list), but provides no explicit guidance on when to use this tool versus siblings like get_song_detail or search_music. There are no exclusions or alternative suggestions, so it falls to implied usage.

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