youtube_list_playlists

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

No annotations available, and the description does not disclose behavioral traits such as data freshness, rate limits, or how missing playlists are handled. Minimal transparency.

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 it lacks essential information. It is not overly verbose, but the terse style reduces usefulness.

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 no output schema and minimal description, the tool definition is incomplete. The description does not help the agent understand how to use the tool effectively or what to expect as output.

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?

With 0% schema coverage, the description should explain parameter usage. It only mentions 'belonging to a YouTube channel', leaving api_key, max_results, and page_token unexplained.

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 'list', the resource 'playlists', and the scope 'belonging to a YouTube channel'. It distinguishes itself from sibling tools like youtube_get_channel or youtube_search by specifying 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?

No guidance on when to use this tool versus YouTube search or other list tools. No mention of prerequisites or context for choosing this tool.

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