+## Manual first-party marketplace entries
+
+Migration writes `openai-curated` entries for eligible source-installed plugins.
+For first-party plugins that live in Codex's bundled or primary-runtime
+marketplaces, add explicit entries after confirming the target Codex app-server
+inventory exposes that marketplace and plugin.
+
+Use the same config shape for every first-party marketplace:
+
+```json5
+{
+  plugins: {
+    entries: {
+      codex: {
+        enabled: true,
+        config: {
+          codexPlugins: {
+            enabled: true,
+            plugins: {
+              chrome: {
+                enabled: true,
+                marketplaceName: "openai-bundled",
+                pluginName: "chrome",
+              },

+    },
+  },
+}

+
+The key under `plugins` is OpenClaw's local config key. `pluginName` and
+`marketplaceName` must match the Codex app-server inventory exactly. If the
+plugin is not listed in `/codex plugins list` or Codex app diagnostics, OpenClaw
+keeps the entry configured but cannot expose its apps to Codex turns.
