+## Editor configuration cleanup
+
+Task [#14](https://git.sendico.io/tech/sxchnge/issues/14) removes the root VS Code
+extension recommendations and launch configuration. Root `.vscode/` is ignored
+so personal editor configuration stays local. Development uses the CLI commands
+in the README. Validation: no tracked root `.vscode` files, ignore rule verified,
+and diff whitespace check passed. Runtime tests are unnecessary for this change.

+Prefer fewer concepts, choices, and controls when they serve the same need; retain
+essential information, accessibility, and recovery. Documentation only.
+Validation: skill-creator `quick_validate.py` passed in an isolated environment
+with PyYAML (the system Python lacked it); `git diff --check` passed. No runtime
+tests were needed. The PR is not merged.
