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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered, and the description adds real value on top by disclosing the return shape: the outcome-category roll-up, the per-record fields, and newest-first ordering. It still says nothing about result limits or pagination, so not 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, tightly packed, with the roll-up purpose front-loaded and query behavior trailing. Dense but every clause carries content; the long enumerated parenthetical is justified by the actual enum-like categories.

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 carries the return-value burden and does so by listing the record fields and ordering. It is nearly complete for a read-only retrieval tool, missing only pagination/limits and sibling routing.

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 the baseline is 3, but the description clarifies the scope of `query` beyond the schema: it matches words in the summary OR the outlet, which the schema's generic 'Words to look for in the records' does not specify. That is genuine added meaning.

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+resource with clear scope: a roll-up of one product's pre-release reports plus the underlying records. The enumerated outcome buckets (Right, Partly right, Wrong, etc.) make the content unmistakable. However it never names or distinguishes itself from close siblings like get_reports or search_reports.

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?

Usage is only implied: an agent can infer this is the tool for a per-product report card, and the optional query's narrowing effect is noted. There is no when-to-use/when-not guidance and no routing to the obvious alternatives get_reports or search_reports.

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