youtube_channel_playlists

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

With no annotations, the description carries full burden. It discloses that it returns 'normalized playlist items' and an optional continuation token, but fails to mention authentication needs, rate limits, or potential side effects. Adequate for a simple read operation but not detailed.

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 two sentences, front-loaded with the main action. Every word is purposeful, with no redundancy or fluff.

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?

Without an output schema, the description gives a basic idea of return data ('normalized playlist items') and pagination. However, it doesn't clarify what 'normalized' means or provide details on field structure, which could aid agent understanding.

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% with descriptions for both parameters. The description adds minimal value beyond schema, only mentioning the continuation token's purpose. Baseline of 3 is appropriate as no extra semantics are provided.

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 verb 'Retrieve' and the resource 'playlists tab for a YouTube channel', precisely defining the tool's purpose. It distinguishes from sibling tools like youtube_channel_videos and youtube_playlist by targeting the specific playlists tab.

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 (to get a channel's playlists) but provides no explicit guidance on alternatives or when not to use. It lacks contrast with sibling tools like youtube_playlist for specific playlist details.

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