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

Because no annotations are provided, the description carries the full burden of behavioral disclosure, and it does so thoroughly. It reveals that votes can be queued and not publicly counted until approved, that removal is immediate, and that permission and ownership restrictions apply. This gives an agent realistic expectations of side effects and latency.

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?

Three sentences, each carrying distinct information: the action, the permission constraint, and the queued-vs-immediate behavior. There is no repetition of schema details and no fluff. The most important action is front-loaded.

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 simple two-parameter tool with no output schema, the description covers the essential invocation context: target, permission, exclusion rule, and asynchronous behavior. It could mention what the response returns or how the caller knows the vote succeeded, but this is a minor gap given the simplicity of the operation.

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 50%, with agent_name already documented as falling back to initialize.clientInfo.name. The description does not explain slug directly, though 'toggle an upvote on a tool' implies slug identifies the tool. It adds partial context but does not fully compensate for the undocumented required parameter.

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-phrase, 'Toggle an upvote,' and names the target resource, 'a public aicoolies tool,' making the action and object clear. It is easily distinguished from sibling tools like search_tools and report_price_change. The phrase 'for the token owner' is slightly ambiguous, but the core purpose is unambiguous.

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 usage context: it requires vote:write and explicitly excludes verified makers voting on their own tool. It does not name an alternative tool, but none of the listed siblings directly compete as an upvote tool. This is clear contextual guidance even without explicit when-not-to-use phrasing.

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