qui_get_torznab_tracker_domains

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

The readOnlyHint annotation already covers the non-destructive nature, so the description does not need to restate it. The description adds useful context about how to structure arguments (path variables, query params, body), which is a behavioral expectation. However, it does not disclose any other traits such as rate limits, pagination, or data format, so it only partially enriches transparency 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 sentence, perfectly concise and front-loaded with the endpoint. No unnecessary words or repetition, making it 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?

While the output schema exists, the tool is part of a large family of similar qui_* tools, and the description provides no semantic context about what tracker domains are or why this endpoint would be used. The generic argument-passing note is helpful, but the lack of domain-specific context means an agent cannot determine if this tool is the right choice or what to expect from it.

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 is a generic container with no specific properties, and the description provides only a generic convention for passing path variables, query values, and body. It fails to list any endpoint-specific parameters (e.g., which path variables or query parameters are expected), so the agent cannot form correct arguments based on this description 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?

The description explicitly identifies the HTTP method (GET) and the exact endpoint (/torznab/indexers/tracker-domains), making the resource clear. However, it does not explain in plain language what 'tracker domains' are or what the response represents, slightly limiting clarity beyond the technical instruction.

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. There is no mention of scenarios, exclusions, or related tools like qui_list_torznab_indexers or qui_get_torznab_indexer, leaving the agent without context for selection.

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