Get playlist

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

Annotations already indicate readOnlyHint=true and openWorldHint=true, so the description's 'Get information' is consistent but adds no additional behavioral context. No contradiction. The description does not disclose any side effects or limitations beyond what annotations provide.

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 sentence, which is concise but lacks depth. It is front-loaded with the key action, but could include more information without becoming verbose. Slightly under-informative for its brevity.

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 a simple tool with one parameter and no output schema, the description provides minimal context. It does not specify what information is returned (e.g., playlist metadata, track list). It is adequate for a read-only lookup but leaves ambiguity about the response content.

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 coverage is 0%, so the description must compensate. It implies that 'playlistId' identifies the playlist, but does not explain its format or how to obtain it. The schema provides type and minimum, but no description. The tool description adds minimal meaning.

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 'Get information about a specific playlist', using a verb+resource structure. It distinguishes from sibling tools like 'get_playlists' by specifying 'specific'. However, it could be more precise about what information is obtained (e.g., metadata, track list).

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 vs alternatives (e.g., 'get_playlists' for list, 'update_playlist' for modification). The description lacks any context on prerequisites or exclusions.

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