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

No annotations are provided, so the description carries the full transparency burden. It discloses two meaningful traits: eligibility ('every citizen may vote') and privacy ('reasons are public'). However, it does not state whether votes are immutable, replaceable, or whether a citizen can vote multiple times, which are important behavioral aspects of a voting operation.

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 two sentences with no filler. The core action and scope are front-loaded in the first sentence, and the second provides important user-facing context. Every word earns its place.

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?

For a 3-parameter tool with no output schema and no annotations, the description is minimally viable but incomplete. It explains what to do, who can do it, and one privacy implication, but it omits the outcome of the vote, voting finality, and any constraints on repeat voting, leaving an agent without a full picture.

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 description coverage is 100%, so the baseline is 3. The description adds little beyond the schema: the phrase 'reasons are public' mirrors the schema's 'optional public reasoning' and does not introduce new meaning or syntax for proposal_id, choice, or reason.

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 verb ('Vote'), a concrete resource ('proposal'), and the scope ('open'), making the tool's purpose immediately distinguishable from siblings like create_proposal or post_message. No ambiguity exists about what this tool does.

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 description provides clear context: it applies to open proposals and states that every citizen may vote. While it doesn't explicitly exclude closed proposals or already-voted scenarios, no sibling tool competes with it, so the guidance is sufficient for basic agent selection.

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