get_livetv_dvrs_by_dvr_id_guide

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

The annotations already communicate readOnlyHint, idempotentHint, and destructiveHint, and the description adds no behavioral context such as response format, pagination, errors, or authentication requirements. The GET method repeats rather than extends what the annotations already imply.

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 short, front-loaded, and easy to scan, with the summary line before the endpoint and argument details. It contains some redundancy between 'Get DVR Guide' and the tool name, but no unnecessary prose.

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?

For a single-parameter read-only tool with an output schema and strong annotations, this is minimally workable. The missing usage context and lack of behavioral detail make it only adequate rather than genuinely helpful.

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. 'dvr_id: The ID of the DVR' provides a basic semantic gloss, but it is minimal and does not explain where the ID comes from or any additional constraints.

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 'Get DVR Guide' and includes the endpoint 'GET /livetv/dvrs/{dvrId}/guide', which clearly identifies the resource and operation. However, it does not distinguish itself from related guide/EPG sibling tools such as list_livetv_epg_guide.

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 alternative DVR or EPG guide tools. The description only restates the endpoint and parameter, leaving the agent to infer the intended use case.

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