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

Annotations already cover the safety profile (readOnly, non-destructive, closed-world), so the description correctly spends its budget elsewhere: it discloses the verdict vocabulary, the four remark states and what each means, and the permission flags returned. It adds no operational behavior such as pagination, ordering, or error conditions, which keeps it below 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?

Purpose is front-loaded, but the remainder is a single dense run-on enumerating every field, enum value, and anchor key. The content largely earns its place given the absence of an output schema, yet the lack of structure (bullets or separate sentences) makes it hard to scan.

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?

There is no output schema, so the description carries the full burden of explaining return values — and it does: review fields, verdict values, remark states, anchor kinds with their key formats, and the anchors/canReview/canAnswer fields. An agent can interpret the response without further documentation.

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?

Only one parameter, and the schema documents it at 100% coverage including its cross-reference to search_wiki. The description says nothing about the id argument, which is acceptable given full schema coverage but adds no value on this dimension.

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 opening states a specific resource — a wiki page's reviews — and narrows it to 'who checked which version of it, and what they found', which is far more than a restatement of the name. It doesn't explicitly name the nearest siblings (review_wiki_page, answer_review_remark, get_wiki_page_reading), so an agent must infer the boundary from the resource word alone.

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: the closing note that 'canReview' and 'canAnswer' say what you may do hints that this tool is a read-then-act entry point for review workflows, but the description never says when to call it versus review_wiki_page or answer_review_remark. No prerequisites, no exclusions, no alternatives.

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