Name	Required	Description
`sort`	No	Alias for `sortBy`. Prefer `sortBy`.
`trim`	No	Ignored if this tool does not support it.
`urls`	No	Alias for `handle`. Prefer `handle`.
`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 videos.
`context`	Yes	Describe the user's underlying goal in one sentence — not the tool you are calling.
`pageSize`	No	Ignored if this tool does not support it.
`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

A4.6/5.0

Behavior4/5

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

Annotations already provide readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds useful behavioral context beyond the annotations: it accepts a channel id or handle and returns a paginated list via cursor. This goes beyond the high-example's 3 because it explains identifier flexibility and pagination explicitly.

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?

Three sentences, each purposeful: purpose+exclusion, identifier options, return+pagination. No filler or redundant phrasing. The core purpose is front-loaded in the first sentence.

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

Completeness4/5

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

Despite 22 parameters, many are aliases or ignored flags with 100% schema coverage. The description covers the essential usage decision (channel id vs handle) and pagination. It doesn't mention sorting, limit, or includeExtras, but those are fully documented in the schema and are optional. For a read-only list tool with no output schema, this is complete enough for correct invocation.

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?

Schema coverage is 100%, so baseline is 3. The description adds value by clarifying that either a channel id or handle is acceptable ('Accepts a channel id or handle'), which is not obvious from the schema where both are marked simply as 'Optional'. It also reiterates cursor usage for pagination, reinforcing the schema's description.

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 action ('List long-form videos'), a resource (YouTube channel), and explicitly excludes Shorts by naming the sibling tool (youtube.channel.shorts.list). This clearly distinguishes it from youtube_channel_shorts_list and youtube_channel_get without needing to inspect the schema.

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

Usage Guidelines5/5

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

Explicitly says 'not Shorts — use youtube.channel.shorts.list', giving a direct alternative and the condition that selects it. It also tells the agent to use the cursor for pagination, providing concrete call guidance. No ambiguity about when to use this tool.

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