+# Apache Magpie — Gemini CLI extension context
+
+This context ships with the Apache Magpie Gemini CLI extension. Gemini has no
+plugin update/lifecycle hook (unlike Claude Code), so this file is how the
+extension prompts you to reconcile after an update.
+
+## Upgrade prompt
+
+The Magpie extension declares its version in `gemini-extension.json`. At the
+start of a session, compare that `version` against the value you last recorded
+in `magpie-plugin-version` under the extension's state directory (create the
+file if it does not exist):
+
+- If the version has **changed** since you last recorded it — the marketplace
+  updated the extension — tell the user, once and non-intrusively:
+
+  > Apache Magpie was updated to `<version>`. If this repo adopts Magpie, run
+  > `/magpie-setup upgrade` to reconcile the snapshot, agentic overrides, and
+  > drift.
+
+  Then record the new version.
+
+- If the version is unchanged, say nothing.
+
+Never run the upgrade yourself: `/magpie-setup upgrade` is a guided,
+user-confirmed action, and Magpie never mutates an adopter repo unattended.
