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

Annotations declare readOnlyHint=false and openWorldHint=true, and the description adds zero context about side effects, permissions, rate limits, or what the call does to state. Calling it a 'Detail API' while annotations mark it non-read-only is unexplained and leaves the agent with no behavioral picture.

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 short sentence is not wasteful by length but is entirely redundant with the title, so it earns no place. Brevity here reflects under-specification rather than tight writing.

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?

With no output schema and no behavioral annotations beyond generic hints, the description must explain return content and usage, and it explains neither. An agent has no idea what fields a policy feed detail record returns or when this tool is preferable to the list endpoint.

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 only one required parameter and the schema documents it fully (100% coverage: a 32-bit string ID sourced from the list response). The description adds nothing beyond that, so baseline 3 applies.

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 a near-verbatim restatement of the tool name/title ('policy Feed Detail API'), with no verb describing the action and no explanation of what a 'policy feed' record actually contains or represents. An agent cannot infer from this sentence what data it gets back.

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 when-to-use guidance at all. The relationship to the sibling list tool nexscope_amazon_policy_feed is only hinted at inside the input schema ('data[].id from list interface response'), not in the description itself, so the description does no routing work.

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