v1_youtube_playlist

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

With no annotations, the description covers cost (1 credit) and a safety warning about data vs instructions. However, it doesn't explicitly state read-only behavior (implied by GET) or discuss auth, rate limits, or other side effects.

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 efficient with three sentences: purpose, endpoint/cost, and safety warning. Front-loaded and no superfluous content.

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 no output schema, the description provides basic context but omits any description of the response format (e.g., what fields the videos contain). Adequate but not comprehensive.

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?

Although schema coverage is 100%, the parameter descriptions are mere repetitions of names (e.g., 'playlist_id' described as 'playlist_id'). The tool description does not add meaning, leaving the roles of optional parameters handle and channelId unclear.

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 the videos of a YouTube playlist', specifying the verb and resource. It distinguishes itself from siblings like v1_youtube_channel_videos (channel videos) and v1_youtube_video (single video).

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 when to use (when needing playlist videos) but does not explicitly mention alternatives or when not to use. For example, it doesn't suggest using v1_youtube_channel_playlists to get playlists or v1_youtube_video for single videos.

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