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

No annotations are provided, so the description carries the burden. It discloses that the link is public, only available for ready recordings, expires after the retainUntil deadline, and that the expiry must be reported with the link. It does not detail error behavior or auth requirements, but the key behavioral facts are present.

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 sentences long, front-loads the main action, and contains no redundant wording. Every clause adds useful information about the link, the readiness precondition, or the expiry reporting requirement.

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 output schema, the description specifies what the caller should expect: a public link plus the retainUntil expiry. For a simple single-parameter getter, this is largely complete; only minor gaps like exact response format or behavior for non-ready recordings remain.

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 coverage is 0%, and the description does not mention videoId explicitly. However, the phrase 'for a ready recording' implies the parameter identifies a recording, adding mild context beyond the schema. The single required string parameter is otherwise self-explanatory.

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 names a specific action and resource: 'Get a public link for a ready recording'. This clearly distinguishes it from the sibling upload, delete, list, and search tools, and the mention of 'public link' and 'ready recording' adds useful scope.

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 description states the key precondition: the recording must be ready, implying this tool is used after upload completion. It does not explicitly name alternatives or when-not-to-use cases, but the condition is clear enough to guide selection.

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