get_downloads_by_channel_json

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds the HTTP method and exact path pattern, which is mildly useful, but does not disclose any additional behavioral details such as authentication needs, rate limits, or response characteristics.

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 appropriately short and front-loaded with the primary action, followed by the endpoint and argument definition. The 'Args' section is clear. It loses a point because the phrase 'Get Plex Downloads' is largely redundant with the tool name and endpoint.

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 simple one-parameter GET with output schema and strong annotations, the description is nearly sufficient. However, it lacks guidance on what valid channel identifiers look like and does not clarify when to select this tool over download-queue-related tools. These are real but limited gaps.

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 must compensate. It only restates that 'channel' is 'The channel identifier', which adds no meaningful detail beyond the schema's bare 'Channel' title. It gives no valid formats, examples, or constraints for channel values.

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 states a specific verb and resource: 'Get Plex Downloads' and 'GET /downloads/{channel}.json'. It clearly indicates this tool returns downloads for a given channel and is distinguishable from sibling download-queue tools by its channel-scoped, JSON-suffixed endpoint.

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 usage guidance is provided. The description does not say when to use this tool versus alternatives, such as download-queue tools, nor does it mention any prerequisites or exclusions. The intended context must be inferred entirely from the tool name.

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