getPlaylistTracks

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 does not mention pagination behavior (despite the limit parameter), whether all tracks are returned by default, or any authentication requirements. The description is purely declarative and lacks contextual behavior.

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, clear sentence that immediately states the tool's purpose. It is front-loaded with the action and resource, and there is no unnecessary verbiage or repetition.

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 simple read tool with two parameters, the description is adequate but not complete. It lacks information about the return format (e.g., whether it returns track metadata, artists, or just IDs) and does not mention any constraints like default limit or pagination. Since there is no output schema, the description should have provided more context, but the schema covers parameter semantics.

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 input schema already provides complete descriptions for both parameters (playlistId as the Spotify ID, limit with range 1-50). The description adds no additional meaning beyond what the schema offers, so the baseline of 3 is appropriate given 100% schema coverage.

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 'Get a list of tracks in a Spotify playlist' uses a specific verb ('Get') and identifies the exact resource ('tracks in a playlist'), clearly distinguishing it from sibling tools like getMyPlaylists or getRecentlyPlayed. It unambiguously states the tool's function.

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 guidance is provided on when to use this tool versus alternatives, such as searchSpotify or getMyPlaylists. There is no mention of exclusions or specific scenarios, leaving the agent to infer usage purely from the tool name and description.

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