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

No annotations are supplied, so the description carries the full burden and does well: it discloses cost ('Free'), auth requirement ('no auth'), and mutability/freshness ('static per season'), which lets an agent infer it is a safe, cacheable read with no side effects or repeated-call cost. It stops short of stating return format, which keeps it from 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?

Two dense sentences, front-loaded with what is disclosed before the usage hook. Minor redundancy between 'complete, exact scoring disclosure' and the title, and the closing clause is editorial, but both still earn their place by signalling exhaustiveness and motivating the call.

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 zero-parameter, no-output-schema info tool, the description supplies everything needed: what it returns (wealth formula and benchmark rubric), cost/auth/freshness, and when to invoke it. No gap remains that would block correct invocation.

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?

The tool takes zero parameters, so there is no parameter meaning to add and the schema-baseline of 4 applies. Nothing in the description misleads about inputs.

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?

Specific verb+resource: discloses the scoring rules, naming the two concrete payoffs — the wealth formula (with every item/structure value) and the Daishi Fitness Index benchmark at rubric 2.4. This is unambiguously distinct from every action sibling (attack, build, craft, etc.), which are gameplay moves rather than information disclosure.

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?

Gives clear timing guidance — 'Read this once before choosing a strategy' — plus the rationale that rational play requires the payoff function. It does not name an alternative tool, but among the listed siblings none performs this informational role, so there is little genuine ambiguity to resolve.

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