+# VS Code extension instructions
+
+## VS Code extension
+
+After every change to this extension, complete the update by compiling,
+packaging, and installing the extension in the connected VS Code environment.
+This includes changes limited to the Log Explorer HTML, CSS, or JavaScript.
+
+- Keep the current extension version unless the user explicitly requests a
+  version change. Do not bump `package.json` or `package-lock.json` automatically.
+- From this directory, run `npm run compile` and the checks appropriate to
+  the change. Report any existing test failures separately.
+- Package with `vsce package --out vscode-appdaemon-<current-version>.vsix`,
+  using the installed or cached `@vscode/vsce` CLI when available. Overwrite the
+  existing VSIX for that version; never pass a version increment to `vsce`.
+- Install that exact VSIX using
+  `code --install-extension ./vscode-appdaemon-<current-version>.vsix --force`.
+- Confirm the installed version with `code --list-extensions --show-versions`.
+  When possible, verify the installed changed files match the packaged files.
+- Tell the user to reload the VS Code window to activate the update. If the
+  connected CLI is unavailable or installation fails, report that limitation
+  clearly and provide the generated VSIX path; do not claim it was installed.
+
+The user's request authorizes this routine local build and installation after
+extension edits. Do not ask for additional conversational confirmation.
