Api privacy personal data cascade info retrieve

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so safety is covered, but the description adds nothing about what the preview contains, whether the target must exist, or what a cascade failure looks like. "Cascade preview" does not contradict the annotations, but it contributes no behavioral context beyond them.

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 followed by a colon, so there is no padding, but the text is a dangling fragment rather than a front-loaded statement — it reads like an unfinished label and conveys less than one complete sentence would.

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 read-only cascade-impact endpoint with no output schema and an undocumented id, the agent needs to know what will be returned (affected objects, counts) and whether the call is a dry-run. Neither is present, so the definition is not sufficient 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?

One required parameter with 0% schema description coverage, and the description says nothing about it — the agent cannot tell whether id refers to a personal data record, a processing, or a parent object. Since the schema only says {"type": "string"}, the description was the only place to disambiguate and it does not.

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:" is a fragment with a colon and no verb or resource; it hints at previewing cascade effects but never says it retrieves cascade-impact info for a personal-data record identified by id. An agent must infer the purpose entirely from the tool name, and nothing distinguishes it from the dozens of sibling *_cascade_info_retrieve tools.

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 (e.g. the destroy/delete counterpart it presumably previews), and no prerequisites or exclusions. The single phrase supplies zero routing information.

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