links

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

No annotations are provided, so the description carries full burden. It only says 'Getting video links', which implies a read operation but does not disclose any side effects, authentication requirements, or rate limits. The description is too minimal to be transparent.

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 concise with a single sentence. While there is no unnecessary text, it is too brief to be informative. Front-loading is not an issue, but the content is minimal.

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?

Given no parameters, no output schema, and no annotations, the description should provide more context about the source of video links and how they are retrieved. The current description is insufficient for an agent to confidently use the tool without additional 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 tool has zero parameters, so schema coverage is 100% trivially. The description explains the output (video links) but adds no parameter-specific meaning since there are none. For a zero-parameter tool, a baseline of 4 is appropriate as the description is sufficient for understanding what the tool returns.

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 'Getting video links', which indicates the tool retrieves video links. However, it does not specify the source or context (e.g., from a social media platform), making it somewhat vague. Compare to sibling tools like 'hls' or 'mediabyshortcode', the distinction is unclear.

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 usage guidelines are provided. The description does not indicate when to use this tool over alternatives like 'get', 'hls', or 'mediabyshortcode', which could also involve video content. This leaves the agent without guidance on tool selection.

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