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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description does add one useful behavioral fact — it requires a linked Solana wallet — but the truncation leaves the actual behavior (deterministic message, idempotency implications given idempotentHint=false, what to do with the returned text) undisclosed.

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?

It is short, but because the single sentence is cut off, it is under-specified rather than concise. There is no front-loaded statement of what the tool returns or what the caller does next.

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?

With no output schema, four undocumented parameters, and no annotations about the return value, the description needs to explain the signing flow and parameter meanings. It reveals only that a linked wallet is involved and the text is for backing a Trana vote vote, leaving an agent unable to call it correctly.

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% for four parameters, and the description says nothing about id, choice, key, or proof — not their format, valid values, or which are optional. The description must compensate here and does not at all.

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 identifies the tool's output — the exact text a linked Solana wallet signs to back a Trana vote on a proposal — which is more specific than the name alone. However, the text is truncated mid-sentence ("(trana_vote..."), and it never states clearly whether this only constructs the message or also submits anything, nor how it differs from wallet_vote or trana_vote.

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?

There is no explicit when-to-use or when-not-to-use guidance. The flow relative to siblings such as wallet_vote, wallet_votes, trana_vote, wallet_link_message, or space_trana_link is only weakly implied by mentioning "your Trana vote".

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