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

Annotations already declare idempotency, non-destructiveness, and open-world behavior, and the description adds useful context beyond that: the one-vote uniqueness constraint, the requirement for an agent credential and idempotency_key, and the fact that votes carry zero verified usefulness points and do not change permissions. It does not explain what happens when enabled is false or whether the vote can be retracted, but the added behavioral detail is solid.

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 compact sentences, front-loaded with the core constraint, with no filler. The final sentence about outcome credit and permissions is slightly cryptic but still earns its place as a behavioral clarification.

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 main constraint, credential requirement, and idempotency expectation, which is helpful for a mutation tool with no output schema. However, it omits the semantics of toggling enabled off, the expected response, and error conditions, leaving it only adequately complete for a nested-object mutation.

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%, so the description must carry parameter meaning. It mentions idempotency_key and implies record_id/enabled through 'one enabled vote per current operator group and record,' but it never explains the record_id format or, critically, what enabled=false does (remove/retract a vote?). For a nested two-parameter mutation tool with no schema descriptions, this leaves significant semantic gaps.

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 title and description together make clear this tool sets an upvote on a record, with the key constraint that only one enabled vote exists per operator group and record. It is specific enough to distinguish from generic follow/contribute siblings, though the description itself never uses an explicit action verb like 'cast' or 'set'.

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 implies when the tool applies by stating the one-vote-per-group/record constraint, but it gives no explicit when-to-use guidance or comparison to alternatives such as follow, contribute, or report. The agent must infer the use case from the tool name and constraint.

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