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

No annotations provided, so description carries full burden. States 'public data' implying read-only. Mentions 'best-effort classification' for include_shorts/include_live. Returns include quotaEstimate, providing usage cost awareness. However, does not mention authentication requirements or rate limits, which would be helpful.

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?

Well-structured with separate sections for description, parameters, returns, and notes. Uses bullet points for clarity. Every sentence adds value. Front-loaded with purpose statement. No unnecessary text.

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 7 parameters, no annotations, and sibling tools, description covers most needed information. Explains returns (items, nextPageToken, quotaEstimate). But misses describing next_page_token parameter and does not reference sibling tools for context. Adequate but could be more 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?

Schema coverage is 0%, so description adds significant meaning. Explains playlist_id, page_token (pagination), max_items, include_shorts/include_live (default false, best-effort), and parts_level (basic/full). However, input schema also includes next_page_token parameter which is not described, causing potential confusion.

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?

Description starts with 'List videos in a playlist' which clearly states verb and resource. Adds 'public data' to clarify scope. Distinguishes from siblings like list_youtube_channel_videos (which lists videos from a channel) and list_youtube_channel_playlists (which lists playlists of a channel).

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 explicit guidance on when to use this tool versus alternatives. Does not mention when not to use it or reference sibling tools for comparison. The description only states what it does, leaving the agent to infer usage context.

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