Api actors cascade info retrieve

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

Annotations declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is at least covered structurally. However, the description adds nothing beyond annotations — it does not say what a 'cascade preview' returns, whether it shows impacted objects counts, or what the open-world behavior means here.

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 single colon-terminated fragment is short but under-specified rather than concise; it reads like a truncated label rather than a front-loaded explanation. Brevity here is a liability, not a virtue.

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 tool requiring an id and belonging to a very large family of similarly named cascade preview endpoints, the description provides essentially no context about output, scope, or usage. An agent cannot confidently invoke this correctly.

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?

There is one required parameter 'id' with 0% schema description coverage, and the description provides no clarification about what the id refers to (actor id, object id, model id) or any format expectations. The description does nothing 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:', which hints at previewing cascade effects but never states a verb+resource pairing or what is being previewed. It cannot be distinguished from the many sibling *_cascade_info_retrieve tools based on this text alone.

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 guidance at all on when to use this tool versus the ~200 sibling cascade_info_retrieve tools or versus the standard retrieve/object_retrieve endpoints. The agent must infer everything from the name.

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