Remove From Playlist

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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false, and openWorldHint=true, so the safety profile is covered. The description adds valuable context beyond annotations: removal applies to every occurrence of the video in the playlist, the video itself is unaffected, and the operation costs 51 quota units.

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 tight sentences plus a quota note. The core action and its scope are front-loaded, and every clause earns its place by preventing a common misunderstanding or surfacing cost.

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 that annotations cover safety and idempotency, an output schema exists, and the input schema documents all parameters, the description is nearly complete. It could optionally mention permission requirements or error behavior, but nothing essential for correct invocation is missing.

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 all three parameters (video, playlist, my_channel) are already documented in the input schema. The description adds no syntax, format, or selection guidance beyond that baseline, so a 3 is appropriate.

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 states a specific verb and resource ('Remove a video from one of your playlists') and adds a distinguishing scope ('every time it appears'), which clearly separates it from siblings like add_video_to_playlist, move_in_playlist, and delete_video. It also clarifies the non-effect on the video itself, preventing confusion with delete_video.

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 gives clear implied context: use this to detach a video from a playlist without deleting the video. It does not explicitly name alternatives or state when-not-to-use, but the 'video itself is not affected' clause effectively contrasts it with delete_video.

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