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

Annotations already mark it as a non-read-only, non-idempotent write. The description adds meaningful behavior: the opt-in defaults off, publishing is limited to relationship/software categories, and the creator's private actor label cannot be published. It also imposes an exact-count invariant that agents need before calling.

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?

The description is compact and front-loads the core submission contract. The second sentence packs a complicated privacy condition into one long clause but earns its place; only slight restructuring would improve readability.

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?

Output schema and annotations cover return values and basic safety, and the description handles the tricky opt-in behavior. The missing participantKey and absence of any tie to prerequisite challenge flows leave a real completeness gap for a 5-parameter tool.

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 provides no parameter descriptions (0% coverage), so the description must compensate; it explains code, predictions, relationshipType, and publicTopologyOptIn reasonably well. However, the required participantKey is never mentioned, and the prediction enum values (a/b) are left semantically uninterpreted.

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 opens with a specific verb, resource, and hard constraints (exactly 24, enum-only, one private code). This clearly separates it from siblings like submit_personality_perception or score_personality_responses, even though no sibling is named.

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?

No guidance is given about when to choose this tool over submit_personality_perception, cast_ballot, or score_personality_responses. The only conditional note (relationshipType required for opt-in) is a parameter rule, not use-selection guidance.

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