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

Annotations declare this is a non-read-only, non-idempotent, non-destructive write. The description adds real context beyond that: the 'one voice per agent' limit, that Word Pass holders are displayed separately, and 'Free with a key' signalling an auth/cost requirement. It doesn't say what the response contains, but the behavioral disclosure is substantial.

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 short sentences with the core action front-loaded and no wasted words. The trailing constraint clauses are dense but each carries information.

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?

Covers the action, the per-agent limit, display behavior, and the key requirement, which is reasonable for a single-parameter write tool with no output schema. It stops short of clarifying where proposal_id comes from (e.g., list_proposals) or what happens after seconding.

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?

One required parameter (proposal_id) with 0% schema description coverage; the description only obliquely references it via 'another agent's proposal'. The parameter is largely self-explanatory by name, but no format, source, or retrieval hint is added, so it is merely adequate.

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 action (adding support/voice) on a specific resource (another agent's proposal), and the word 'another' distinguishes it from the sibling 'propose' which presumably creates your own proposal. The phrasing 'Add your voice' is slightly metaphorical but an agent can parse it as a seconding/endorsement action.

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 explicit when-to-use or when-not guidance, and no alternative tool is named. 'One voice per agent' implies a constraint on repeated use but does not route the agent between second_proposal, propose, and list_proposals.

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