ytptube_create_preset

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

Annotations already indicate readOnlyHint=false, destructiveHint=false, and idempotentHint=false. The description adds no behavioral details beyond the fact that it creates a preset, such as whether it overwrites existing presets, requires authentication, or has side effects. It does not contradict the annotations, but it also does not enhance them.

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 concise sentence with no fluff, front-loading the core action and resource. However, it is so brief that it sacrifices necessary detail, though that is more of a completeness issue than a conciseness issue.

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 nested input schema with multiple properties and no output schema, the description is severely inadequate. It does not explain the purpose of presets, how they are used in downloads, or what the effects of creation are. The agent is left without sufficient context to correctly invoke the tool.

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 input schema has zero description coverage for the 'preset' object and its properties (name, folder, cookies, template, description). The description 'Create a download preset' provides no parameter-level meaning, leaving the agent with no additional guidance on what fields are expected or how they are used.

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 'Create a download preset' clearly states the action (create) and the resource (a download preset). It distinguishes itself from sibling tools like list_presets, get_preset, patch_preset, and update_preset by using the specific verb 'create'.

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 provides no guidance on when to use this tool versus alternatives such as patch_preset or update_preset. It does not mention any prerequisites, scenarios, or exclusions, leaving the agent to infer the appropriate context.

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