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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely new context: what each part actually returns and where field meanings live (fields.md in the JSON download). It omits error behavior for an unknown id, which keeps it from a 5.

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 sentences, no filler, with the core action front-loaded before the part semantics. The second sentence is dense and somewhat run-on, but every clause carries information the agent needs.

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, the description correctly steps in to describe both return shapes, which is the main completeness risk here. Given a simple two-parameter read tool and strong annotations, little else is missing beyond failure modes and whether findings are paginated.

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 coverage is 100%, so baseline is 3, and the description goes beyond the terse enum ("findings" (default) or "pack") by explaining what each enum value yields. The report_id parameter is only covered by the schema's own pointer to list_support_insights_reports.

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?

States a specific verb and resource ("Read one Support Insights report by id") and the singular "one ... report" implicitly contrasts with the list_support_insights_reports sibling. It further decomposes the tool into its two returnable parts, so an agent knows exactly what it retrieves.

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 description gives clear selection guidance between the two modes: "findings" for ranked findings/scope notes/verified facts, "pack" for the full evidence pack. It does not state any when-not-to-use condition or explicitly name the sibling list tool, but the context is unambiguous.

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