+### Claude Code users: also install the official Convex plugin
+
+If the user is on Claude Code, recommend installing the official Convex plugin
+from the marketplace alongside the AI files. The two are complementary: the AI
+files give Claude Convex coding rules in any harness, while the plugin adds
+Claude-Code-specific wiring you can't get from a static file.
+
+```
+/plugin install convex
+```
+
+What the plugin adds on top of the AI files:
+
+- A `convex-expert` subagent for code-writing inside `convex/` — runs in its own
+  isolated subagent context so the deep rules (object-form function syntax,
+  validator requirements, index naming, runtime-error decoder) don't burn
+  main-thread tokens.
+- A runtime-error monitor that streams `npx convex logs`, surfaces matched
+  errors as Claude notifications, and self-guards on unlinked projects.
+- The Convex MCP server (`npx convex mcp start`) auto-wired — gives Claude live
+  deployment introspection (`tables`, `function-spec`, `data`, `run-once-query`,
+  `logs`, `env list/set/get`) instead of guessing from generated types.
+
+Plugin source and issues: <https://github.com/get-convex/convex-backend-skill>.
+
+If the user is on a non-Claude-Code harness (Cursor, Windsurf, Codex, etc.),
+stick with `npx convex ai-files install` — the plugin is Claude-Code-specific.
