+## Changes
+
+- Replaces `/mcp` with `/tools` for broader Codex capability diagnostics covering plugins, tool providers, MCP servers, and skills.
+- Improves grouped slash-command and diagnostic output so structured command results are easier to scan.
+- Streamlines the README usage guide around current panel, thread, composer, and diagnostics workflows.
