get_by_id_api

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

The description aligns with the readOnlyHint and idempotentHint annotations by using the verb 'Read'. It adds no extra behavioral context such as external API calls, rate limits, or return format, but the annotations already cover the safety profile, so the lower bar is met.

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 concise and well-structured: 'Read Newznab.' is front-loaded, followed by the HTTP path and a clear 'Args:' block with one parameter per line. While the parameter list is long, the path/query distinction justifies the repetition and the format is easy to scan.

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 33 parameters and a schema with zero descriptions, the description is insufficient for an agent to call the tool correctly. It omits parameter semantics, response details, and any indication of when to use this tool, leaving significant gaps despite the presence of an output schema and annotations.

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 0% description coverage, so the description must compensate. It adds path/query location labels for each parameter, which is helpful, but it does not explain the semantic meaning of any parameter (e.g., what 't', 'q', or 'cat' represent), leaving the agent without crucial information for correct usage.

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 opens with 'Read Newznab,' providing a clear verb and a resource name, and includes the HTTP endpoint 'GET /{id}/api'. However, it does not explain what 'Newznab' refers to or how this tool differs from closely named siblings like get_indexer_by_id_newznab, leaving some ambiguity for an agent.

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 about when to use this tool versus alternatives. The description only lists parameters and does not mention that it targets a specific indexer's Newznab API or provide any exclusion criteria.

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