+# Skip Init Container Evaluation
+
+Starting in ACS 5.0, policies evaluate init containers by default. This script adds `skipContainerTypes: ["INIT"]` to all existing policies that don't already have an evaluation filter, preserving the pre-5.0 behavior where init containers were not evaluated.
+
+## Usage
+
+```bash
+export ROX_ENDPOINT="central.example.com:443"
+export ROX_API_TOKEN="your-api-token"
+
+./skip-init-container-evaluation.sh
+```
+
+## Requirements
+
+- ACS 5.0 or later
+- `curl` and `jq` installed
+- An API token with policy read/write permissions
+
+## What it does
+
+1. Checks that Central is running ACS 5.0+
+2. Lists all policies and prompts for confirmation before making changes
+3. For each policy without an existing evaluation filter, adds `skipContainerTypes: ["INIT"]`
+4. Skips policies that already have a container type filter set
+5. Skips build-only policies (container type filters are not applicable at build time)
+
+## Policy-as-Code users
+
+If you manage policies via SecurityPolicy CRDs and a GitOps workflow, update your policy manifests directly instead of running this script. Add the following to each policy spec:
+
+```yaml
+spec:
+  # ... existing policy fields ...
+  evaluationFilter:
+    skipContainerTypes:
+      - INIT
+```
