get_playlists

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

With no annotations provided, the description bears full responsibility. It discloses batch fetching behavior, a cap on tracks per playlist via max_tracks, and per-item failure capture, which are crucial behavioral traits beyond the input schema.

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 sentence that front-loads the main action and efficiently conveys key behavior (batch, track limit, failure capture) without any redundant words.

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?

For a 2-param tool with an output schema, the description adequately covers batching and error behavior. However, the required 'values' parameter is not defined, and the output schema's presence does not excuse the omission of the input parameter's purpose.

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%, so the description must explain parameters. It adds meaning for 'max_tracks' (limits tracks per playlist) but completely omits the required 'values' parameter, leaving it undefined.

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 'Fetch many playlists at once' using a specific verb and resource, and distinguishes itself from singular siblings like 'get_playlist' by emphasizing batch retrieval with per-item failure capture.

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 for fetching multiple playlists and mentions failure handling, but does not explicitly state when not to use it or provide alternatives like 'get_playlist' for single playlist retrieval.

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