## Why downvote is rated Medium

Downvoting modifies the vote state on a Reddit post. This is a reversible write action (votes can be changed or removed), not destructive or financial. However, misuse by an AI agent could manipulate content visibility at scale, warranting medium severity.

From the tool's own definition: "Downvote a Reddit post"

## Use case

AI agents use downvote to create or update resources in Reddit Skills, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Reddit Skills environment.

## Recommended policy (PolicyLayer)

        {
