Name	Required	Description
`sort`	No	Alias for `sortBy`. Prefer `sortBy`.
`trim`	No	Ignored if this tool does not support it.

`user`	No	Alias for `handle`. Prefer `handle`.
`limit`	No	Ignored if this tool does not support it.
`cursor`	No	Opaque pagination cursor returned by a previous response.
`handle`	No	Optional YouTube channel handle for the request.
`offset`	No	Ignored if this tool does not support it.
`sortBy`	No	Optional sort order for the returned YouTube Shorts.

`userName`	No	Alias for `handle`. Prefer `handle`.
`username`	No	Alias for `handle`. Prefer `handle`.
`channelId`	No	Optional YouTube channel id for the request.
`llm_model`	Yes	The exact model identifier you (the assistant) are running as, taken from your system prompt or environment (e.g. "claude-opus-4-8", "gpt-5.2"). Used for analytics only. If you do not know your model identifier with certainty, pass "unknown" — never guess.

TDQS

A4.3/5.0

Behavior4/5

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

Annotations already supply readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds value by disclosing that it returns a list and that cursor-based pagination is expected, which is behavior beyond what the schema's cursor parameter alone conveys.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with zero filler: the main action and scope are front-loaded, followed by the essential identifier and pagination guidance. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has 21 parameters (mostly aliases and ignored flags) and no output schema. The description covers the main identifier and pagination, but says nothing about default ordering, what fields each Short entry contains, or how to treat the numerous alias/ignored parameters, leaving the agent to navigate that landscape from the schema alone.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 100% schema description coverage, the baseline is 3. The description adds value by explicitly pointing to channel id or handle as the key identifier among 21 parameters, helping the agent avoid the many alias and 'ignored' parameters in favor of channelId/handle.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (List), resource (Shorts), and scope (from a YouTube channel) with the explicit qualifier 'not long-form videos', which distinguishes it from siblings like youtube_channel_videos_list and youtube_shorts_trending_list. The fact that it accepts a channel id or handle further pins down the operation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'not long-form videos' qualifier tells the agent when not to use this tool, and 'Accepts a channel id or handle' explains how to specify the target. It doesn't name the alternative tool explicitly (e.g., youtube_channel_videos_list), but the context is clear enough that an agent can route correctly.

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