Api stored libraries 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 covered. The description adds no context beyond that — nothing about what the cascade preview returns, what depends on a library, or how expensive/whether it can be large (openWorldHint=true).

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?

It is short, but brevity here is under-specification rather than conciseness: two words and a colon convey essentially no information. There is nothing front-loaded because there is nothing substantive to front-load.

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 one-parameter read tool with no output schema, the description would need to explain the cascade-preview concept and return shape to be usable. It omits both, and nothing in the sibling set disambiguates it.

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 the single required parameter is bare "id" with no type-level documentation. The description never clarifies whether this is a stored library id, nor what form it takes, so it 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?

"Cascade preview:" is a fragment, not a statement of what the tool does. It gestures at a preview of cascade behavior for a stored library but never names the verb or resource, and against dozens of sibling *_cascade_info_retrieve tools it gives no basis for telling this one apart.

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 exclusions, and no mention of alternatives such as stored_libraries_retrieve, stored_libraries_object_retrieve, or stored_libraries_tree_retrieve. The agent must infer entirely from the tool name that this is a pre-deletion/pre-unload impact check.

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