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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: no authentication requirement, no pagination behavior, no ordering, no return format. 'Mine' weakly implies a user-scoped, authenticated call, but that is inference from the name rather than stated behavior.

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 contains no filler and is trivially front-loaded, but the brevity is a result of under-specification rather than disciplined editing. It is appropriately sized for a label, not for a tool definition.

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?

With a required parameter, no annotations, and no output schema, the description should explain what 'queued' means, whether authentication is required, and what the response contains. None of that is present, leaving the agent unable to confidently invoke the tool from the definition alone.

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% and the single region parameter is documented with an enum in the schema, so the baseline of 3 applies. The description adds no additional meaning about how region affects the result set, such as whether it filters the queue or selects a server.

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 is a three-word noun phrase that essentially restates the tool name ('mine' = my, 'videos' = videos); only 'queued' adds any new information. It does not name a verb or explain what is being returned, so an agent must infer that this lists the authenticated user's queued video uploads rather than, say, videos they have watched or favorited.

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?

There is no guidance on when to use this tool versus the sibling videos or videos_editable endpoints, and no stated prerequisites. The only implicit signal is that 'mine' scopes results to the calling user, which the agent must derive from the name alone.

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