+# GitHub Workflow Updates Required
+
+Due to OAuth token scope limitations, the following workflow files need to be updated manually to complete the Bun to Node.js migration:
+
+## Files to Update
+
+### 1. `.github/workflows/format-check.yml`
+
+Replace the Bun setup and commands with Node.js:
+
+```yaml
+# Replace lines 19-37 with:
+      - name: Setup Node.js
+        uses: actions/setup-node@39370e3970a6d050c480ffad4ff0ed4d3fdee5af # v4.1.0
+        with:
+          node-version: "22"
+          cache: "npm"
+
+      - name: Install dependencies
+        run: npm ci
+
+      - name: Check formatting
+        run: npm run format:check
+
+      - name: Check if files would change
+        run: |
+          if ! git diff --exit-code; then
+            echo "❌ Files are not properly formatted. Run 'npm run format' to fix."
+            exit 1
+          else
+            echo "✅ All files are properly formatted."
+          fi
+```
+
+### 2. `.github/workflows/release.yml`
+
+Replace the Bun setup with Node.js:
+
+```yaml
+# Replace lines 23-29 with:
+      - name: Setup Node.js
+        uses: actions/setup-node@39370e3970a6d050c480ffad4ff0ed4d3fdee5af # v4.1.0
+        with:
+          node-version: "22"
+          cache: "npm"
+
+      - name: Install dependencies
+        run: npm ci
+```
+
+## How to Apply
+
+You can apply these changes by:
+
+1. Manually editing the files in the GitHub web interface
+2. Using a local git client with proper credentials
+3. Applying the staged changes from this branch (they're already prepared)
+
+## Verification
+
+After updating, the workflows should:
+- Use Node.js 22 instead of Bun
+- Use `npm ci` for installing dependencies
+- Use `npm run` for running scripts
+- Reference npm commands in error messages
+
