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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuine extra context: idempotency ('safe to repeat'), canonicality ('reads current server state and does not manufacture company facts'), and the authentication prerequisite (active company access). However, the 'Confirmation boundary' sentence is padded with unrelated boilerplate (reversible save, plan refresh, standing policy) that dilutes rather than sharpens the read-specific behavior.

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?

The purpose is front-loaded and the labeled clauses (Prerequisite, Canonicality, Idempotency) aid scanning, but the final sentence is bloated with an enumerated list of irrelevant confirmations. The dangling 'plus every prerequisite stated above' references nothing in a standalone definition and wastes space.

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 names the return payload (hash and web signing URL), which an agent needs. It is nonetheless incomplete for a 4-parameter tool with 0% schema coverage, since the meaning of companyId, consentId, and pagination bounds is never established. Adequate but with clear gaps.

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 0%, so the description carries the full burden for four parameters, and it largely fails: it implies single-page reads but never explains the page range (1-100), and it says nothing about companyId, consentId, or the nested _corply_context object. Only the paginated-read concept is conveyed, leaving three parameters undocumented in both schema and description.

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 description states a specific verb and resource: reading one page of the exact frozen PDF addressed to the connected account, and names the payload (hash and web signing URL). It explicitly distinguishes itself from the signing counterpart with 'this does not sign or record review', so an agent can separate it from sign_my_governed_document without opening either schema.

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?

It gives clear usage context ('Read all pages before deciding') and a negative boundary ('this does not sign or record review'), which routes the agent away from the signing tool. It never names the alternative tool explicitly or states a full when-not-to-use condition, so it stops short of the top tier.

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