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

Annotations already cover the read-only/idempotent profile, and the description adds a lot beyond them: deterministic ordering (newest first), the status lifecycle values, that editor notes and the public URL are surfaced once live, and concrete auth mechanics with two accepted key types. It also explains a non-obvious semantic — both keys return the whole account because reviews belong to the owner, not a single product.

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?

Three sentences, front-loaded with the resource, scope and ordering before usage and auth. The auth sentence is long and carries a parenthetical navigation path, but that detail is operationally useful rather than 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?

No output schema exists, so the description shoulders the return-value burden and does so by naming the surfaced fields and ordering. Auth, scope and status vocabulary are all covered; the only remaining gap, pagination behavior, is low-stakes for a 2-parameter optional-filter list tool.

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?

With 50% schema description coverage, the description should carry more weight. It restates the status enum values but says nothing about the `limit` parameter, defaulting, the 50 cap, or what happens when results exceed the limit — the one genuinely ambiguous dimension is left entirely to the schema.

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 ("List the review articles") plus scope ("across every product you own"), and enumerates what comes back: editorial status, editor notes, public URL. It implicitly separates itself from the sibling generate_review via "Use to check what happened to a generated review," though it never names a sibling explicitly.

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?

"Use to check what happened to a generated review" gives a clear triggering context and implicitly contrasts with generate_review. There is no explicit when-not guidance (e.g. how to inspect a single review) and no naming of alternatives for narrower listings, which keeps it off a 5.

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