get_youtube_transcript_ytdlp

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

With no annotations, the description carries the full burden for behavioral disclosure, yet it only states the method (yt-dlp) and parameter syntax. It does not mention potential failures (e.g., no transcript available), return format, rate limits, or authentication requirements, leaving the agent without critical operational context.

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, leading with the purpose and then directly listing arguments. No wasted words; every sentence earns its place, and the structure makes the tool easy to parse quickly.

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 absence of an output schema and the presence of multiple transcript-related siblings, the description lacks essential context about return format and when to choose this tool over others. The simplicity of the tool does not justify the missing guidance on expected output and selection criteria.

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 descriptions are absent (0% coverage), so the description must compensate. It does list both parameters, clarifies that video_url is a YouTube URL, and adds examples and a default for language, providing meaningful semantic value beyond the raw schema.

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 transcript), resource (YouTube video), and method (yt-dlp). The phrase 'most reliable method' distinguishes it from sibling tools like get_youtube_transcript, making the purpose unambiguous and differentiated.

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?

'Most reliable method' provides clear context for preferring this tool, but there is no explicit when-not or alternative naming. The absence of exclusionary guidance prevents a 5, but the comparative statement offers useful direction.

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