create_livetv_dvrs_by_dvr_id_reload_guide

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the intent of causing a guide reload but does not disclose side effects like cache invalidation, potential latency, or whether the DVR must be online. It offers minimal behavioral context beyond the annotations, so a 3 is appropriate.

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?

Three short lines convey the action, the endpoint, and the argument. The primary purpose is front-loaded in the first sentence, and there is no filler or redundant explanation. Every sentence earns its place.

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 command with an output schema and useful annotations, the core action and argument are documented. However, it lacks usage guidance and operational context (e.g., what happens after the reload is triggered, whether it blocks). It is minimally viable but leaves gaps an agent might need filled for correct invocation in 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?

Schema description coverage is 0%, so the description carries responsibility for parameter meaning. It states 'dvr_id: The ID of the DVR,' which clarifies the purpose of the only parameter. However, it adds little beyond the schema's title 'Dvr Id' and does not explain how to obtain a valid DVR ID or whether it corresponds to list_livetv_dvrs output. Basic but adequate for a simple integer identifier.

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 a clear verb+resource statement: 'Tell a DVR to reload program guide.' It names the specific action and resource, and the embedded POST endpoint reinforces the operation. It does not explicitly contrast with siblings like delete_livetv_dvrs_by_dvr_id_reload_guide, but the purpose is unambiguous.

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?

The description provides no guidance on when to invoke this tool versus related DVR tools, such as get_livetv_dvrs_by_dvr_id_guide, delete_livetv_dvrs_by_dvr_id_reload_guide, or update_livetv_dvrs_by_dvr_id. There are no prerequisites, no mention of how frequently a reload should be triggered, and no exclusions. The agent is left to infer usage entirely from the action name.

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