ytptube_get_ytdlp_options

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

Annotations already declare the tool as read-only, idempotent, and non-destructive. The description adds the word 'active' to indicate it reads the current effective configuration, but doesn't disclose what the returned data looks like or any edge cases. It provides a minimal amount of additional context 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?

A single, unambiguous sentence: 'Read the active yt-dlp option configuration.' No wasted words, front-loaded with the action verb, and easy to parse.

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 zero-parameter read-only getter, the description is adequately complete given the safe annotations. It could be improved by mentioning the output format or what 'option configuration' includes, but the simplicity of the tool lowers the burden. No output schema exists, so a brief hint about the return value would add value, but it's not critical.

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 tool has zero parameters, so there is nothing to document. The schema fully covers this with an empty properties object. The description doesn't need to add parameter details, and the baseline of 4 fits.

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 reads the active yt-dlp option configuration. It identifies the specific resource (yt-dlp options) and the action (read), which is sufficient to grasp the basic purpose. It doesn't explicitly distinguish itself from related siblings like get_system_configuration, but the name and description are specific enough.

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?

No guidance is provided on when to use this tool versus alternatives such as validate_cli_options or get_system_configuration. There is no mention of context, prerequisites, or scenarios where this tool is preferred.

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