Cancel Download

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

With no annotations provided, the description carries the full burden, and it does convey the core behavior (canceling a download) and the endpoint, which implies a state change (cancellation). However, it does not mention potential side effects, error conditions (e.g., what if the download is not queued?), or success/failure responses. It adds some value beyond the name by including the endpoint and 'queued' qualifier, but could be more explicit.

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, information-dense sentence that front-loads the action and includes the endpoint for developer verification. No wasted words; every part contributes to understanding.

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 cancel operation with one parameter and no output schema, the description is largely complete. It clearly communicates the action and the endpoint, and the 'queued' qualifier provides essential context. Missing are any caveats about idempotency or error behaviors, but given the low complexity, this is a minor gap.

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 schema documentation (100% coverage) already explains that download_id is from sdnext_civitai_download, and the tool description does not add extra meaning to this parameter beyond that. Since schema coverage is high, the baseline of 3 is appropriate; the description does not need to repeat parameter details.

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 action ('Cancel a queued CivitAI download') with a specific verb and resource, and includes the full REST endpoint. This distinguishes it from sibling download-related tools by explicitly indicating the 'cancel' operation. The mention of 'queued' adds important scope nuance.

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 the tool is used to cancel downloads but provides no explicit guidance on when to use it versus alternatives, nor any prerequisites or exclusions (e.g., only works on queued downloads, not already completed ones). While the 'queued' qualifier hints at context, it does not explicitly tell the agent when to invoke this tool or what happens if invoked inappropriately.

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