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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds meaningful context beyond that by detailing what the response contains, including provenance, replaced values, the open question, unread words, sent status, and any offer – valuable since there is no output schema.

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 definition is a single compact sentence that front-loads the resource and then lists the returned facets with no filler. The colon-separated list is dense but readable; a clearer verb or shorter phrasing would tighten it further.

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?

For a read-only tool with full annotation coverage, complete parameter schema, and no output schema, the description adequately explains the return shape. Remaining gaps are minor: 'Firstmise requirement' and 'words not yet read' are not defined, and it does not clarify whether the result is a point-in-time snapshot.

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% and both parameters are described in the schema, including that the id comes 'from an earlier answer' and the token is a receipt token to keep private. The description adds no parameter-level meaning beyond that, so the baseline 3 is appropriate.

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 makes clear this returns the full current state of a single requirement, enumerating the contents (values with provenance, replacements, open question, unread words, sent status, offer). It is specific about the resource and payload, though it never uses an explicit verb like 'retrieve' and does not name a sibling it differs from.

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?

There is no guidance on when to call this versus alternatives such as inspect_offer, inspect_delivery, or edit_requirement, nor any mention of prerequisites like first obtaining the id and token. The 'as it stands' phrasing hints at current-state reading but leaves all routing to inference.

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