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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds one real piece of behavioral context ('Requires API key'), which is useful, but says nothing about pagination behavior or result volume beyond what the schema states.

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?

Two short sentences, front-loaded with the core identification before the filtering and auth details. Every clause carries information and there is no filler.

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 simple, non-destructive read tool with zero required parameters and a fully documented schema, the description covers purpose, filters, and the API key requirement. Lacking an output schema, it could briefly describe what a recommendation record looks like, but the gap is minor.

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%, so all four parameters are already documented, including limits, offsets, and the status enum with its pending default. The description restates the status values and names section filtering, which adds nothing beyond the schema; baseline 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?

It names a specific verb ('View') and resource ('intelligence inbox') and clarifies the content as 'recommendations discovered by the Scout', so an agent knows it is a read of recommendation records. It doesn't explicitly distinguish itself from close siblings like discover_intelligence, get_inbox_stats, or review_recommendation, leaving that routing to inference.

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?

The filter hints ('Filter by status ... or section') imply the intended browsing use case, and the default of pending is documented in the schema. However, there is no explicit statement of when to prefer this over discover_intelligence or get_inbox_stats, and no exclusions.

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