Remove YouTube Playlist Item

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

With no annotations, the description carries the burden of behavioral disclosure. It does reveal the destructive nature ('Removes') and the confirmation requirement, but omits details about reversibility, permissions, or side effects. This is adequate but not rich.

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, front-loaded with the action, with no redundant filler or unnecessary detail. The structure is concise and effective.

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?

This is a destructive mutation tool with no annotations and no output schema, yet the description gives minimal context about prerequisites, error behavior, or return values. The coverage is insufficient for safe usage.

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 0%, so the description must compensate. It only vaguely ties 'one exact item' to playlist_item_id and 'owned playlist' to url, and restates the confirm constraint. It does not explain parameter formats, edge cases, or relationships.

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 ('Removes'), the target ('one exact item'), and the scope ('owned playlist'), distinguishing it from sibling tools like youtube_add_playlist_video or youtube_reorder_playlist_item. It is specific and unambiguous.

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?

It specifies the prerequisite of an owned playlist and the requirement for confirm:true, providing clear context for when to use this tool. However, it does not explicitly mention alternatives or when-not-to-use it, so it falls short of a 5.

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