get_youtube_transcript

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not mention output format, error handling, rate limits, or what happens if extraction fails. The only behavioral hint is 'primary extraction method,' which is not elaborated.

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 purpose sentence and a simple Args list. Every word is functional, and the structure is easy to parse. No filler or redundant content.

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 the presence of sibling tools and no output schema or annotations, the description is incomplete. It does not specify the return format, when to use alternative extraction methods, or any constraints. An agent would struggle to decide between this and the ytdlp variant or understand what to expect as a result.

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 description adds some semantics beyond the schema by labeling video_url as 'YouTube video URL' and providing examples for language codes ('en', 'es'). However, it does not explain accepted formats, fallback behaviors, or edge cases, so it only partially compensates for the 0% schema description coverage.

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 clearly states the tool's action (Get the transcript), the resource (YouTube video), and the specific method (primary extraction method), which distinguishes it from the sibling tool get_youtube_transcript_ytdlp. The verb and resource are explicit.

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?

There is no guidance on when to use this tool versus its alternatives. The phrase 'primary extraction method' implies it is the default but does not explain when to choose ytdlp, plain text, or other variants. No exclusions or conditional advice are provided.

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