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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the endpoint and parameter layout, with no mention of side effects, return behavior, authentication requirements, or whether this is a read-only discovery operation.

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, efficiently worded sentence with no unnecessary words. It front-loads the endpoint and provides the essential calling convention. It is concise, though it sacrifices needed detail.

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 tool's complexity (many sibling tools, no annotations, generic schema, output schema present), the description is too thin. It doesn't explain the purpose of discovery, what triggers it, or any constraints. The output schema exists, so return values needn't be described, but the description still lacks sufficient context.

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 provides no parameter details (coverage 0%), so the description must compensate. It clarifies the wrapper structure: path variables, query params, and a JSON body. However, it doesn't specify which path variables, query keys, or body fields are relevant for this endpoint, leaving substantial ambiguity.

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 names a specific endpoint (POST /torznab/indexers/discover) and uses the verb 'Call' to indicate it invokes that endpoint. 'Discover' distinguishes it from related tools like qui_list_torznab_indexers, though it doesn't explain what discovery entails.

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. It only explains argument passing conventions, not the intended use case or situations where one might prefer a sibling like qui_list_torznab_indexers or qui_search_torznab.

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