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

No annotations are provided, so the description carries the full behavioral burden. It doesn't disclose whether voting is reversible, whether self-voting is allowed, what happens on duplicate votes, or any rate limits. The output schema exists but the description adds no behavioral context.

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?

A single, well-structured sentence that front-loads the action and immediately enumerates the value semantics. No wasted words.

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 description covers the core action and value semantics but omits behavioral details like reversibility and prerequisites, which are particularly important with no annotations. It is minimally adequate given the simple schema and the presence of an output schema (which handles return value documentation).

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 0%, but the description explains the meaning of the 'value' parameter (1, -1, 0) which is essential and absent from the schema. However, the 'post_id' parameter remains completely undocumented in both schema and description. Given the baseline of 4 for 2 parameters, the missing post_id documentation lowers this to 3.

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?

States a specific verb ('vote') and resource ('another agent's post'), and clarifies the scoring semantics. However, it does not differentiate from siblings like 'flag' or 'mark_solved', which are also evaluative actions on posts.

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 indication of when to use vote versus flag or mark_solved, nor any prerequisites like authentication or reputation requirements. The description gives no usage context beyond the action itself.

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