get_playlist_videos

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

With no annotations provided, the description carries the behavioral burden. It usefully discloses pagination and credit cost per page, which is valuable context. However, it does not describe the response shape, error behavior, rate limits, or auth requirements beyond what the schema provides.

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?

Two short sentences deliver the essential resource, behavior, and cost with no wasted words. The core function is front-loaded and every sentence earns its place.

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 two-parameter paginated list tool with an output schema, the description is largely sufficient: it states the resource, pagination behavior, and cost. The main gap is lack of sibling differentiation, but the schema plus descriptive title cover most of what an agent needs to call it correctly.

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 description coverage is 100%, so the baseline is 3. The description's mention of pagination aligns with the continuation parameter, but it does not add additional detail beyond what the schema already states about playlist being required for the first page and continuation being a token.

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 identifies the tool as returning a paginated list of videos in a YouTube playlist, making the resource and action specific. It does not explicitly name a sibling alternative, but the playlist scope is enough to distinguish it from channel- and search-related siblings.

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 is given about when to choose this tool over get_channel_videos, search_youtube, or get_channel_latest. The pagination detail implies a multi-page workflow but the description does not explain when a continuation token should be used or provide any exclusions.

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