v1_youtube_channel_playlists

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

With no annotations, the description adds important behavioral details: cost of 1 credit, the API endpoint, and a safety warning that responses are data not instructions. This helps the agent understand side effects and safe usage.

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?

Three focused sentences, no wasted words. Information is front-loaded: purpose, endpoint/cost, then input constraints and warning. Ideal structure.

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 parameterless-GET-like tool with 3 optional but one-required params, the description covers purpose, cost, input constraints, and safety. Could add pagination or output format but not essential.

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 does not add meaning beyond what the schema provides. The requirement of 'one of' is already noted in parameter descriptions.

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 the tool gets a YouTube channel's playlists, using a specific verb and resource. It distinguishes from sibling tools like v1_youtube_channel or v1_youtube_channel_videos by focusing on playlists.

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 provides input requirement: one of handle, channelId, url. However, it does not explicitly guide when to use this tool versus alternatives like v1_youtube_channel_videos, leaving the agent to infer based on the resource name.

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