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

Annotations already declare readOnlyHint=true, openWorldHint=true, destructiveHint=false, so the safety profile is covered elsewhere. The description adds nothing beyond that – no mention of whether records can expire, what fields are returned, or any access constraints for a policy/compliance data source.

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 the brevity comes from under-specification rather than efficiency – a single sentence that duplicates the title. Nothing is front-loaded because there is no substantive content 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?

A one-parameter detail lookup with annotations and no output schema should still tell the agent what kind of record it retrieves and how it relates to the list tool. The description leaves both unaddressed, so the agent can only navigate by tool-name pattern matching.

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 100% and the id property is documented precisely (32-bit string, sourced from data[].id in the list response). The description contributes nothing on parameters, but with full schema coverage the baseline of 3 is appropriate.

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 only restates the name and title: 'Amazon ABA & Business Insights: policy Feed Detail API.' There is no verb and no statement of what the tool actually retrieves or returns. The word 'Detail' hints that it fetches a single record, but the agent must infer that entirely from the tool 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?

No guidance whatsoever on when to use this versus alternatives. The obvious sibling, nexscope_amazon_policy_feed (the list endpoint), is never mentioned, even though the schema's id parameter explicitly references 'data[].id from list interface response.'

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