Ytdlp Check Environment

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

Description adds context beyond annotations by listing specific components checked (ffmpeg, ffprobe, cookies, plugins, policy). Annotations already indicate safe, idempotent read operation.

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?

Two sentences, front-loaded with purpose, no redundancy. Every sentence provides essential information.

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 zero parameters, presence of output schema, and annotations covering safety, the description is fully adequate. It covers when to use and what is checked.

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?

No parameters, baseline 4. Description adds meaning by specifying what the check encompasses, which is not evident from the schema alone.

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?

Clearly states the tool checks environment readiness for yt-dlp workflows, differentiating it from sibling tools that perform actual downloads or listing operations.

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?

Explicitly recommends use before first download or when misconfiguration is suspected, providing clear usage context. Does not explicitly state when not to use, but sufficient for a check tool.

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