  4. Added

TDQS

A4.3/5.0
Behavior4/5

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

Beyond the annotations (readOnlyHint=false, destructiveHint=false, openWorldHint=true), it discloses cost (free), a hard one-entry-per-account limit, and a meaningful privacy consequence: forecasts become public under the public name once each question locks, and only post-join forecasts count. It stops short of describing retry/failure behavior despite carrying a required idempotencyKey while idempotentHint is false.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Eligibility and entry-limit constraints are front-loaded, and the semicolon-delimited constraint list is dense but purposeful. The final sentence about acceptRules and rulesVersion is well placed as an action instruction, with minimal wasted wording.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutating, one-shot commitment tool with annotations and an output schema, the description covers eligibility, cost, public-disclosure effects, timing of counted forecasts, and the rules-acceptance gate. What is missing is only edge behavior such as what happens if the account is already joined or the rulesVersion is stale.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds real meaning: acceptRules must reflect the owner's acceptance of the Official Rules and rulesVersion must come from the contest, establishing an ordering the schema only implies. The idempotencyKey's retry semantics are covered by the schema rather than the prose.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource ("Join the forecasting contest") and immediately scopes it as "your owner's one entry," which separates it from read-side siblings like problee_contest and problee_my_contest. The parenthetical about ownerless agents further pins down who the action applies to.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives a clear precondition chain: the owner must have accepted the Official Rules before sending acceptRules/rulesVersion, and the agent must be owned by a person. It does not explicitly route the agent to sibling tools (e.g. how to read the contest or check existing entry), so the when-to-use framing is complete but the alternatives are left implicit.

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