Api perimeters cascade info retrieve

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

The annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so safety is covered. The description contributes only the vague word "preview" and does not explain what a cascade preview actually returns or why it differs from a normal retrieve, so added value is minimal though not contradictory.

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 text is short, but this is under-specification rather than conciseness: a two-word fragment with a trailing colon that conveys almost nothing and is not front-loaded with any actionable information.

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?

No output schema exists, so the description should explain what the cascade preview returns and how it relates to the other perimeters endpoints; it does neither. Against a very crowded sibling namespace, this leaves the agent without what it needs to call the tool confidently.

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% and there is a single required `id` parameter whose meaning (which object's id? a perimeter id?) is never clarified in the description or schema. One undocumented param prevents the zero-param baseline of 4.

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?

"Cascade preview:" hints at the resource concept (cascade info) but is a fragment, not a verb+resource statement. It does not distinguish this tool from the dozens of sibling `*_cascade_info_retrieve` tools, and never says it operates on perimeters (that comes only from the 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?

There is no when-to-use guidance, no mention of alternatives such as the plain perimeters retrieve, and no stated preconditions. The agent is left to infer everything 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.
