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

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key behavioral traits: it's a destructive action (implied by 'cancels'), has specific preconditions (only works on 'running or queued reloads'), and mentions outcomes ('Free up resources', 'Emergency stop'). However, it doesn't specify error handling or authentication requirements, leaving some gaps.

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 well-structured and front-loaded with the core purpose in the first sentence. The 'Use cases' and 'Note' sections are efficiently organized, with each bullet point and sentence earning its place by providing actionable context without redundancy. It's appropriately sized for the tool's complexity.

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 moderate complexity (destructive action with one parameter), no annotations, and no output schema, the description is largely complete. It covers purpose, usage guidelines, and behavioral constraints effectively. However, it lacks details on return values or error responses, which would be helpful for an agent invoking the tool.

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 100% description coverage, with the single parameter 'reloadId' documented as 'The reload task ID to cancel'. The description adds no additional parameter semantics beyond this, so it meets the baseline of 3 where the schema does the heavy lifting. No compensation is needed given the high schema coverage.

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 specific action ('Cancels a running reload task') and resource ('in Qlik Cloud'), distinguishing it from sibling tools like 'qlik_trigger_app_reload' (which starts reloads) and 'qlik_get_reload_info' (which retrieves information). The verb 'cancels' is precise and 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 explicit usage guidelines with a 'Use cases' section listing four scenarios (e.g., 'Stop long-running reload that's hung') and a 'Note' specifying when to use ('Only running or queued reloads can be cancelled') and when not to use ('Completed or already failed reloads cannot be cancelled'). This clearly differentiates it from alternatives like 'qlik_get_reload_status' for checking status.

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