get_channel_videos

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

With no annotations, the description carries the full behavioral burden. It discloses retrieval of recent videos and the two sort modes, and 'Get' implies a read operation. However, it does not clarify what 'recent' means, whether results are paginated, what data is returned, or any quota/rate-limit 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 is two short, front-loaded clauses with no filler. It states the core purpose first and then adds the sorting capability efficiently.

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 schema covers the invocation details, but there is no output schema and no annotations, so the description needs to explain the return shape and the scope of 'recent videos.' These gaps are not fatal for a simple getter, but they leave an agent with ambiguity about output fields and the exact selection criteria.

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%, so the baseline is 3. The description mentions 'sorting by date or view count,' which mirrors the order enum, but it adds no additional meaning beyond the schema. The other parameters are already fully documented in the schema.

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 states a specific action and resource: 'Get recent videos from a YouTube channel.' It also lists the two sorting modes, which clarifies the operation. It is distinct from obvious siblings like get_channel_info, but it doesn't explicitly name alternatives to sharpen differentiation.

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?

No guidance is provided about when to use this tool instead of search_videos, search_within_channel, get_playlist_items, or get_channel_info. The phrase 'from a YouTube channel' implies a listing use case, but no explicit context, exclusions, or alternative routing is given.

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