youtube_remove_from_playlist

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

No annotations are provided, so the description carries the full burden. It states the action is 'Remove' (implying mutation) but does not disclose potential side effects, authentication requirements, irreversibility, or error behavior. The only added transparency is clarifying the ID type, which is more parameter semantics than behavioral disclosure.

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 concise and well-structured: a one-sentence purpose, a usage tip, and an args section. Every sentence adds value, with no filler or redundancy. It is front-loaded with the main action and then details the parameter.

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 tool with a single parameter and no output schema, the description covers the essential aspects: what it does, how to get the required ID, and what the ID is. It could mention authentication prerequisites or the outcome of a successful removal, but these are not critical for such a simple operation, and the guidance is otherwise sufficient.

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?

The schema provides only the parameter name and type without any description. The tool description adds meaningful clarification by stating that playlist_item_id is 'The playlist item ID (not the video ID)' and explains how to find it. This compensates for the 0% schema coverage and helps prevent a common misuse.

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 action: 'Remove a video from a playlist.' This is a specific verb + resource that distinguishes it from sibling tools like add_to_playlist or create_playlist. The purpose is unambiguous and not a tautology.

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 concrete guidance on where to obtain the required playlist_item_id, mentioning both youtube_list_playlists and the Data API. It implicitly tells the user the prerequisite step before invoking this tool, though it doesn't explicitly discuss when not to use it or compare to alternatives.

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