pl_video_latest

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

No annotations are present, so the description should disclose behavioral traits. It mentions 'smart-ranked' but does not explain what that entails, nor does it cover authorization, rate limits, or data freshness. The return type is partially described but lacks detail on array metadata.

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 extremely short but omits critical information. While concise, it fails to add value beyond the name and schema, making it under-specified rather than efficiently helpful.

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 no annotations, no output schema, and 0% schema parameter coverage, the description is woefully incomplete. It does not explain how to use the tool effectively or what the results represent in context.

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?

The input schema has two parameters (tags, limit) with no description in the schema (0% coverage) and no explanation in the tool description. The agent receives no guidance on valid values, formats, or the effect of limit or tags.

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 'Latest video, smart-ranked' and lists return fields, making the basic purpose clear. However, it does not differentiate from sibling tool pl_video_popular, and the name suggests a single video while the return is an array, causing slight ambiguity.

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 on when to use this tool versus alternatives like pl_video_popular or other video tools. There is no mention of context, prerequisites, or exclusions.

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