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

The description labels the call as a submission (consistent with readOnlyHint=false), ties it to a single issued nonce, and adds that provenance is server-assigned, which tells the agent not to send client identity. It does not detail finality or failure outcomes, but the annotations and output schema cover some of that burden.

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 sentences, both information-dense: the first states the action and scope, the second clarifies server provenance. No filler or repetition of schema details.

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?

The core submit path is clear and an output schema exists, so return values do not need describing. However, with seven required parameters and no property descriptions, the definition does not explicitly point the agent to request_ballot_challenge as the source of the issued challenge/nonce or state that the nonce is single-use, leaving some workflow context implicit.

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?

With 0% schema description coverage, the description carries the burden. It gives semantic meaning to selfChoices/predictionChoices ('enum-only vectors') and to challengeId/nonce ('issued'), but it leaves packId, packVersion, and schemaVersion semantically unexplained beyond their raw schema constraints.

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 states a specific action ('Submit'), a specific resource ('self and prediction vectors'), and a scoping condition ('one issued challenge and nonce'). It is clear enough to distinguish from receipt/read-only sibling tools, though it does not explicitly name sibling submission tools such as submit_personality_perception.

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?

The phrase 'for one issued challenge and nonce' communicates the key precondition: cast a ballot only after a challenge and nonce have been issued. It gives clear context but stops short of explicitly listing when-not-to-use cases or naming alternative submission tools.

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