• [nitpick] Consider adding an inline comment explaining why the escape key event is prevented when a renaming operation is in progress to clarify the intended user experience.

• TestAssetRename covers only the happy path. Adding tests for edge cases—extension mismatch, duplicate new name, invalid slug, or missing original file—would improve coverage and robustness.

func TestAssetRename(t *testing.T) {

• There's a stray double-dash list item (-- [ ]). Update to a proper Markdown list (- [ ]) to render correctly.

After a successful rename, the component remains in edit mode. Consider calling setEditingFilename(null) (or equivalent) after onReload() to exit the rename state.

Suggested change

	onReload()
	onReload()
	setEditingFilename(null)

This treats any os.Stat error besides "not exist" as the file already existing. Use err == nil to detect an existing file, and handle other errors separately to avoid misclassification.

Suggested change

	if _, err := os.Stat(newFullPath); !os.IsNotExist(err) {
	return "", fmt.Errorf("new asset already exists: %s", newFilename)
	if _, err := os.Stat(newFullPath); err == nil {
	return "", fmt.Errorf("new asset already exists: %s", newFilename)
	} else if !os.IsNotExist(err) {
	return "", fmt.Errorf("could not check asset existence: %w", err)

[nitpick] Consider adding an explicit return type (e.g., Promise<{ url: string }>) to renameAsset for clearer type safety and better IDE autocomplete.
