List channel videos

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

The annotations already establish read-only and idempotent behavior, and the description adds useful beyond-annotation context: results are ordered newest first, statistics are included, and the call costs roughly 2-3 quota units. It does not mention pagination or exact return fields, but the core behavioral traits are disclosed.

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 one front-loaded sentence that packs the essential purpose, sort order, stats, channel format, and quota cost without any filler. Every clause contributes useful information.

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?

The description is adequate for selecting and invoking the tool, especially with the annotations covering safety and the schema providing defaults and bounds for max_results. However, because there is no output schema and the parameter descriptions are absent, the agent is left without explicit details about return shape or the exact meaning of with_stats and max_results.

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?

With 0% schema description coverage, the description needed to carry parameter meaning, but it only clarifies the required channel parameter (ID or @handle). The with_stats and max_results parameters are left to inference from their names and defaults, so the description only partially compensates for the missing schema descriptions.

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 the tool lists a channel's latest uploads, newest first, with statistics, and notes the channel can be identified by ID or @handle. It is specific about the resource and sort order, though it does not explicitly contrast itself with sibling tools like search or get_videos.

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 phrase 'Latest uploads for a channel' implies this is the tool to use when you need a channel's recent videos, which provides contextual guidance. It does not, however, state when to prefer an alternative or when not to use this tool, leaving the usage boundary to inference.

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