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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds real side-effect context beyond that: the video leaves the Community and Kinetune's featured row at once, and reward credits are returned. It remains ambiguous about what happens to the loves ('with the loves it had').

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?

It is short, and the side effect leads. But the text is duplicated — 'its Look private again' appears twice across a run-on sentence fragment — so wording does not fully earn its place even at this length.

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 single-parameter destructive toggle with annotations covering mutability and idempotency and a fully documented schema, the description supplies the needed outcome details: community removal, featured-row removal, credit return. Return values are not explained, but no output schema exists and the effects are described instead.

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?

There is a single required parameter with 100% schema description coverage, so the schema already carries the burden. The description adds nothing about video_id format or where to obtain it, which is the correct baseline of 3 rather than a strength.

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 gives a concrete verb+resource ('Take a video out of the Community') plus the resulting state ('its Look is private again'), which is the inverse of share_video and clearly distinguishable from delete_video. The phrasing is garbled and repeats the 'Look is private again' idea twice, which blunts an otherwise clear statement.

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 only guidance is 'Ask the user first,' which usefully signals a confirmation step before a destructive action. There is no explicit statement of when to choose this over delete_video or cancel_video, so the agent must infer the alternative from the tool name.

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