Remove a video from a playlist

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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the mutation and repeat-safety profile is covered. The description adds one genuinely useful clarification — that the underlying video survives, only the playlist membership is removed — but says nothing about permissions, behavior when the video is absent from the playlist, or whether item positions shift.

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?

A single front-loaded sentence with no filler, and the parenthetical is well placed to prevent a destructive misread. It is arguably under-specified rather than overly long, which is a different problem than verbosity.

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 low-complexity mutation with annotations covering safety and no output schema, the essentials are largely present, but one of three parameters is undocumented and the description omits failure modes (video not in playlist, unknown channel) that matter for a destructive operation.

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 67%, with channel and playlist documented in-schema (default-channel omission and playlist id-or-exact-title) while video_id carries no description anywhere. The description adds no parameter meaning at all, so it neither compensates for the undocumented video_id nor reinforces the matching semantics of the playlist title.

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?

States a specific verb and resource ('Remove a video from a playlist') and the parenthetical '(the video itself is not deleted)' carves out the scope so it is not confused with delete_video. It does not explicitly name the inverse/nearby siblings (add_to_playlist, move_in_playlist), so differentiation is only partial.

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 no when-to-use context, no prerequisites (e.g. the playlist must exist, the video must currently be a member), and no routing to alternatives such as move_in_playlist or delete_playlist. The agent must infer the appropriate situation entirely from the name.

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