reddit_vote

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

The description does not disclose any behavioral traits beyond the basic action. With no annotations, the agent is left unaware of side effects, such as whether the vote is immediately visible, if it can be changed, or if there are rate limits. The dir parameter description in the schema hints at behavior, but the description itself lacks transparency.

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?

The description is a single, concise sentence with no wasted words. It is appropriately sized for a simple action but could benefit from more detail without being verbose.

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?

Given the lack of annotations and output schema, the description is insufficient. It does not explain return values, error conditions, or practical usage context (e.g., how to obtain the id for a post/comment). The tool's complexity warrants more information.

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 33% (only dir has a description). The description adds no additional meaning for access_token or id beyond their names. For a tool with low schema coverage, the description should compensate, but it does not.

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 clearly states the verb 'Vote' and the resource 'a Reddit post or comment'. It effectively distinguishes from sibling tools like reddit_comment (which creates a comment) and reddit_post (which creates a post).

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 guidance on when to use this tool versus alternatives (e.g., reddit_comment or reddit_post for submitting content). No mention of prerequisites like authentication (though access_token is required) or appropriate contexts for voting.

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