Api reference controls cascade info retrieve

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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is known. 'Cascade' implies some impact analysis, but the description does not disclose what cascade means here (deletion impact on applied controls? on requirements?), so it adds almost no behavioral context beyond the annotations.

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?

Two words plus a trailing colon is not conciseness but under-specification; there is no front-loaded statement of purpose and nothing else to structure.

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?

A read-only, single-parameter retrieve with no output schema could be adequately described in one sentence, but this definition never explains what the preview contains or how an agent should interpret the response, leaving the call under-specified.

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 coverage is 0% for the single required `id`, and the description does not say what entity that id identifies (a reference control, presumably) or any format expectations. Only the name hints at it, so the description fails to compensate for the schema gap.

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 is the fragment "Cascade preview:" – it hints at a preview of cascade effects but never states the resource (reference controls), the verb, or what the preview returns. Against ~50 sibling *_cascade_info_retrieve tools, an agent cannot tell which object type this previews without parsing the tool name.

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 indication of when to use this versus the many other cascade_info or retrieve endpoints, no prerequisites, no mention of how the id is obtained. The colon even suggests truncated text, offering nothing actionable.

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