qui_list_torznab_indexers

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

With readOnlyHint=true already provided, the description adds no additional behavioral context. It restates the GET method but doesn't mention response characteristics, permissions, pagination, or other side effects, so it adds no value beyond 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 concise sentence that directly states how to call the endpoint and how to structure arguments. There is no wasted text or redundancy.

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 that the output schema exists and readOnlyHint is present, the description is minimally adequate, but it lacks domain-specific context about Torznab indexers, list size, or filtering options. It doesn't mention what the response contains or how to interpret the resource, leaving the agent to rely on the output schema and tool name.

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 schema has a free-form 'arguments' property with no descriptions, and the description helps by explaining how to pass path variables, query params, and body fields. However, it doesn't specify which query parameters or body this endpoint supports, leaving the agent to infer the actual semantics.

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 names the HTTP method and endpoint path (GET /torznab/indexers/), making the action and resource clear. However, it does not explicitly say 'list' or 'retrieve all indexers', and lacks differentiation from the singular sibling qui_get_torznab_indexer, so it's not a perfect 5.

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?

There is no guidance on when to use this tool versus alternatives. The description only explains how to structure arguments, not the contextual use case or when to prefer this over related tools like qui_discover_torznab_indexers.

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