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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so safety is covered. The description earns credit by disclosing the shape of the returned state — provenance per value, what each value replaced, the open question, unread words, send status, and attached offers — which is valuable because no output schema exists.

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?

A single front-loaded sentence with no filler, and the resource comes before the enumeration of contents. It is compressed to the point of being slightly cryptic ('words not yet read', 'any offer on it'), but nothing is redundant.

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 field enumeration carries the return-value burden and does so adequately. What is missing is relative scoping: it never says how this differs from sibling reads like describe_proposition or interpret_requirement, nor what happens if the id or token is invalid.

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 100%; both the uuid 'id' ('from an earlier answer') and the private 'token' are documented in the schema. The description adds nothing about either parameter, so the baseline 3 applies.

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 names the resource ('A Loadfactor requirement') and enumerates what the read returns: provenance ('where it came from'), replacements, open question, unread words, sent status and any offer. The verb is implicit rather than stated, and no sibling (e.g. describe_proposition, interpret_requirement, list_propositions) is named to distinguish this single-requirement read from them.

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 when-to-use guidance, no exclusion of alternatives, and no precondition stated beyond what the schema implies. An agent must infer from the name alone that this fetches one full requirement snapshot rather than a list or an interpretation.

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