ytptube_validate_cli_options

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description's 'without starting a download' largely restates this instead of adding new behavioral context such as error handling, return format, or side-effect details beyond the annotations.

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 a single, front-loaded sentence with no filler. It efficiently conveys the core purpose and a key behavioral constraint, making every word count.

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?

Despite the rich annotations and simple one-parameter schema, the description is incomplete for safe invocation. It does not explain the required args syntax nor describe what the tool returns after validation, and the lack of an output schema means the description should cover that gap but does not.

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?

With 0% schema description coverage, the description must compensate, but it only says 'yt-dlp CLI options,' which is a broad indication of content. It does not explain the expected format of the args string (e.g., raw command line, argument list, quoting, or delimiters), leaving significant ambiguity for a single required parameter.

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 the specific action verbs 'Parse and validate' and identifies the resource as 'yt-dlp CLI options,' which clearly states what the tool does. The qualifier 'without starting a download' distinguishes it from sibling tools like ytptube_add_downloads and ytptube_get_ytdlp_options.

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 use as a safe pre-flight validation step ('without starting a download') but does not explicitly state when to use it versus alternatives. No sibling tools are referenced, so the usage context is only implied, not clearly delimited.

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