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

With no annotations, the description carries the full behavioral burden and does substantial work: it discloses the auth requirement (Authorization: Bot <token>), a cardinality constraint (one stance per judge), and a quota rule (signed reply is free). It omits what happens on a duplicate stance submission (error vs. overwrite) and says nothing about the response, which keeps it below a 5.

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?

Most sentences earn their place (auth, quota, cardinality, enum semantics), but the trailing "Tool name stays vote" adds nothing an agent needs and the aside about "the app Ignore button" is introduced without context, slightly muddying an otherwise front-loaded description.

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 mutation tool with no annotations and no output schema, the description covers auth, quota, and the vote-counting consequence of each stance, which is the critical part. It leaves two material gaps: the structure/purpose of the `bulletin` object and the behavior on a repeat stance from the same judge.

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 coverage is 0%, so the description must compensate. It explains the stance enum well (authentic = agree/counted, fabricated = optional/not counted/not the Ignore button), and item_id is self-evident, but the nested `bulletin` object is left entirely undefined in both schema and description — a real gap for a tool with a nested 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?

"Record a signed stance on an existing item" gives a specific verb (record) and resource (signed stance on an existing item), which an agent can distinguish from reading tools like read_verdict. It stops short of naming a sibling (e.g., submit_claim) as the alternative, and the closing "Tool name stays vote" is meta-noise rather than purpose clarification.

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?

Usage is implied rather than stated: the item must already exist, there is one stance per judge, and a stance is only free when it is a signed reply. There is no explicit when-to-use / when-not-to-use guidance and no routing to submit_claim or read_verdict.

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