get_playlist_info

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

With no annotations, the description should disclose behavioral traits. 'Get information' is vague—it doesn't specify whether it returns metadata, owner, followers, or restrictions. The agent cannot infer usage constraints or side effects (e.g., read-only).

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, no redundant information. It is appropriately concise for a simple tool. Slightly reduced because it could be more informative without adding length.

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 tool has an output schema (not shown), the description should clarify what information is returned. With 15+ sibling tools, more context is needed to differentiate behavior. The single sentence leaves the agent underinformed.

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 100%, so the description of playlist_id as 'Playlist ID' is adequate but adds no extra meaning. The description does not elaborate on how the parameter is used. A 3 is baseline for high coverage with minimal additional value.

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 uses a clear verb ('Get') and resource ('information about a playlist'), which is specific enough. However, it does not distinguish from siblings like get_playlist_tracks, which also retrieves playlist data but focuses on tracks. A 4 reflects good clarity but missing differentiation.

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 like get_playlist_tracks or compare_playlists. The description lacks context for selection, making it difficult for an AI agent to choose correctly among many siblings.

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