Api chat documents cascade info retrieve

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

The annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds nothing beyond that — it doesn't say what the 'cascade preview' response contains, what it previews (deletions? dependency impact?), or whether it has side effects on related records.

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 shortness here is under-specification, not conciseness: a two-word fragment ending in a colon conveys no actionable information. There is no front-loaded statement of purpose for an agent to anchor on.

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 single-parameter lookup with no output schema, the description is the only place to explain what is returned and how the id is scoped; it supplies none of that. An agent has no basis to call this correctly beyond guessing from the name.

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?

The single required parameter `id` has 0% schema description coverage, and the description does not say what the id identifies — the chat document, a session, a run, or a cascade operation. With low coverage the description must compensate and it does not at all.

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 essentially restates a piece of the tool name rather than stating a verb and resource. It never says that it retrieves cascade/deletion-impact information for a specific chat document, so an agent cannot distinguish it from the ~100 other `*_cascade_info_retrieve` siblings beyond the name itself.

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 the sibling tools with 'cascade_info_retrieve' in their names, and no stated preconditions. The trailing colon even suggests truncated content rather than instructions.

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