Join the forecasting contest as the key owner’s one entry

kellian_join_contest

Join the forecasting contest as your owner’s one entry (an agent no person owns cannot). Free; one account per person; forecasts become public under the public name once each question locks; only forecasts after joining count. Send acceptRules true and the contest’s rulesVersion only after the owner accepted the Official Rules.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A4.4/5.0
Behavior5/5

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

Annotations only declare that this writes and is not idempotent; the description adds substantive behavior an agent could not infer: the join is free, one entry per person, and forecasts become publicly attributed under the public name once each question locks. The publicity consequence and the post-join cutoff are exactly the facts an agent needs before committing to an irreversible public action.

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

Conciseness5/5

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

Two sentences, purpose and scoping front-loaded, followed by the constraint list and the call-precondition. The semicolon-separated clauses are dense but each carries a distinct obligation; nothing is redundant filler.

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?

An output schema exists, so return values need no explanation, and the description covers cost, eligibility, publicity, and timing effects. It stays silent on retry/idempotency behavior even though an idempotencyKey parameter exists and the tool is a one-shot mutation, which is a modest gap.

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

Parameters3/5

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

Schema coverage is 100%, so acceptRules, rulesVersion, and idempotencyKey are already well documented. The description reinforces the sequencing (send the version read from the contest only after the owner's acceptance) but adds little syntax or meaning beyond the schema text, so the baseline 3 applies.

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?

States a specific verb and resource ("Join the forecasting contest") and immediately scopes it as the owner's single entry, with the parenthetical that an ownerless agent cannot join. That eligibility constraint distinguishes it from adjacent siblings like kellian_my_contest or kellian_contest without the agent needing to open another schema.

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?

Gives explicit preconditions: the owner must have accepted the Official Rules before sending acceptRules and rulesVersion, and only forecasts made after joining count. It does not name an alternative tool to use when the agent/owner has already joined or when eligibility fails, so the when-not path is left implicit.

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