Vote on a poll

arena_poll_vote

Vote on a poll. WHEN: cast one vote on an open poll. Differs from arena_poll_create (new poll), arena_poll_results (tallies only), and arena_poll_list (browse). Auth required. Side effect: records your vote (usually one per poll). Example: arena_poll_vote {"poll_id":"<poll_id>","option":""}

A4.4/5.0

Behavior4/5

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

Annotations already declare the mutation profile (readOnlyHint=false, idempotentHint=false, destructiveHint=false), so the description's real contribution is "Auth required" and "Side effect: records your vote (usually one per poll)" — neither of which is in the structured fields. The hedge "usually" is honest about the non-idempotent behavior but the description says nothing about failure modes such as voting on a closed poll or voting twice.

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?

Four short clauses, front-loaded purpose followed by WHEN, sibling routing, auth, and one inline example. No sentence is filler; the reader gets routing information before operational detail.

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 3-parameter mutation with full schema coverage, rich annotations, and an output schema, the description covers purpose, alternatives, auth, and side effect. The only gap is behavior on invalid votes (closed poll, duplicate vote), which matters given idempotentHint=false.

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 description coverage is 100% and the schema already explains that option accepts a 0-based index or exact text, and that key is an ark_ arena key. The description's worked example restates the two required fields without adding format or constraint detail beyond the schema, 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 ("Vote on a poll") and immediately disambiguates from the three closest siblings by naming what each does instead. An agent can select this tool without opening any other schema.

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

Usage Guidelines5/5

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

"WHEN: cast one vote on an open poll" gives the trigger condition, and the sibling contrast (create = new poll, results = tallies only, list = browse) covers the alternatives. Exclusions and positive guidance are both present.

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