+# DEPRECATED — the `databricks-ai-dev-kit` Claude Code plugin
+
+The **`databricks-ai-dev-kit`** Claude Code plugin published by *this repo* is
+**deprecated and no longer published**. It has been removed from the marketplace
+(`marketplace.json` lists no plugins) and `plugin.json` is marked
+`"deprecated": true`. These files are kept only for historical reference.
+
+> **This is not a move away from plugins.** Skills are still delivered as a plugin
+> for the agents that support one — just the *official* `databricks` plugin managed
+> by the Databricks CLI, not this repo's marketplace plugin. See "How skills install
+> now" below.
+
+## Why
+
+- Skills are now delivered through the Databricks CLI: `databricks aitools install`
+  (Databricks CLI v1.0.0+), backed by
+  [github.com/databricks/databricks-agent-skills](https://github.com/databricks/databricks-agent-skills).
+  The main installer (`install.sh` / `install.ps1`) already delegates to it.
+- The CLI owns the install lifecycle (`install` / `update` / `uninstall` / `list`),
+  so skills no longer need a repo-published marketplace plugin to be bundled and
+  auto-loaded.
+
+## How skills install now
+
+`databricks aitools install` decides delivery per agent:
+
+- **Claude Code, Codex, GitHub Copilot** — installs the official **`databricks`
+  plugin** through each agent's own plugin CLI (a *different* plugin from the retired
+  `databricks-ai-dev-kit` one).
+- **Cursor, OpenCode, Antigravity** — writes **raw skill files** (no headless plugin
+  install available).
+- `--skills-only` forces raw skill files for every agent.
+
+So on Claude Code you still get a plugin — the CLI-managed `databricks` plugin —
+rather than the deprecated `databricks-ai-dev-kit` plugin.
+
+## Migration for existing plugin users
+
+Use either of the following to get the up-to-date skills:
+
+- Run the installer:
+
+  ```bash
+  bash <(curl -sL https://raw.githubusercontent.com/databricks-solutions/ai-dev-kit/main/install.sh)
+  ```
+
+- Or install directly via the Databricks CLI (v1.0.0+):
+
+  ```bash
+  databricks aitools install
+  ```
+
+## Notes
+
+- The frozen historical copies of the bundled skills live at git tag `v0.1.14`.
+- Files under `.claude-plugin/` remain in the repo for reference only; they are
+  no longer installed or published.
