RECOMMENDED RULE

The rule that runs get_pr_diff safely

get_pr_diff Allowed

get_pr_diff is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_pr_diff": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Nitrostack, apply this rule, and every get_pr_diff call is checked against it from then on.
