## Why reply_comment is rated Medium

This tool creates new data (a comment reply) on Reddit, which is reversible (comments can be edited or deleted by the user). It does not execute arbitrary code, delete data, move money, or read without side effects.

From the tool's own definition: "Tool description states 'Reply to a specific comment on a Reddit post.' The verb 'Reply' indicates creation of new content (a comment)."

## Use case

AI agents use reply_comment 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)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Reddit Skills:

```json

  "tools": {
    "reply_comment": {
      "limits": [
