What downvote does on Reddit Skills
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.
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.

Attacks that exploit this kind of access
The rule that runs downvote safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Reddit Skills, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For downvote, this is the rule to start with:
downvote stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Reddit Skills, apply this rule, and every downvote call is checked against it from then on.
Questions about downvote
Downvote a Reddit post. It is categorised as a Write tool in the Reddit Skills MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Reddit Skills MCP server in PolicyLayer and add a rule for downvote: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Reddit Skills. Nothing to install.
downvote is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the downvote rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for downvote. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
