Remove Video from Playlist

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

Annotations already indicate idempotentHint=true and destructiveHint=false. The description adds that it returns confirmation with updated video count, which is useful. No contradictions. Could mention if removal affects other users or if it's reversible.

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 extremely concise with two sentences and an args list. It is front-loaded with the action and efficiently communicates the core information with no wasted words.

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 the simple operation with two required string params and no output schema, the description covers the purpose, parameters, and return value. It is complete enough for an agent to use correctly, though it could mention potential errors or side effects.

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 100%, so the input schema already documents both parameters. The description repeats them without adding extra meaning beyond what the schema provides. Baseline 3 applies.

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 'Remove a video from a playlist,' which is a specific verb and resource. It distinguishes from siblings like 'neptime_add_video_to_playlist' and 'neptime_remove_watch_later' by focusing on playlist removal.

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 does not provide explicit when-to-use or alternatives. For a simple removal, it's implied, but no guidance on prerequisites (e.g., ownership) or when not to use (e.g., if playlist is invalid).

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