suwayomi_get_download_status

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

No annotations are provided, so the description must carry the behavioral burden. It states the action (check) implying a read-only operation, which is useful, but does not disclose what information the tool returns or if there are any side effects. The description is minimal but sufficient for a status-checking tool.

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 concise sentence that conveys the core purpose without any fluff. It is appropriately sized for a tool with no parameters and a simple function.

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 simplicity (no parameters, no nested objects) and the presence of an output schema, which likely details return values, the description is complete enough for an agent to call it. It could briefly mention what information is returned (e.g., list of downloads, progress percentages), but the output schema may compensate.

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 tool has zero parameters, so the description does not need to add parameter semantics. Baseline for zero parameters is 4, and the description accurately indicates the tool requires no arguments by not mentioning any.

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 clearly states the tool checks the download queue and active progress, identifying a specific verb and resource. It is distinct from siblings like suwayomi_download_chapters, which initiates downloads, so an agent can reasonably infer the difference, though it could explicitly mention that no modifications are made.

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 implies it should be used to check download status, which is a common operation, but it does not explicitly state when to use this tool versus others. For instance, it does not mention that this is for monitoring rather than starting downloads, but the context is clear enough for an agent to infer.

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