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

No annotations are provided, so the description must carry the full behavioral disclosure burden. It reveals that the transcript is public and that availability is conditional, but it does not state what happens when a transcript is not available (error, null, empty result) nor what the return value looks like. Safety is implied by 'Retrieve', but the conditional behavior is left unspecified.

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?

A single well-structured sentence that states the action, resource, scope, and a key condition without any filler or redundancy. The core scope is front-loaded and every word earns its place.

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?

For a one-parameter read-only tool, the purpose is clear enough for basic use, but the absence of an output schema and annotations means the description should at least hint at the return format or behavior when the transcript is unavailable. The 'when available' caveat is stated but its consequences are not, leaving minor but real ambiguity.

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 0%, and the description never mentions the 'id' parameter by name. However, saying 'for one video' clarifies that the id refers to a video identifier, adding meaning beyond the bare schema. It does not specify the expected id format or note that the id likely corresponds to the same one used by get_video.

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 uses a specific verb ('Retrieve') and a specific resource ('public transcript for one video'), clearly distinguishing it from sibling tools like get_video, recent_videos, and search_videos, which deal with videos themselves. The qualifier 'when available' adds precision about the tool's 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 implies the tool should be used when a transcript for a specific video is wanted, but it provides no explicit guidance on when to prefer this tool over its siblings or what to use instead for other needs. There are no exclusions or alternative mentions, leaving the agent to infer from the sibling tool names.

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