  "description": "Change a Charming app's URL slug — the human-readable, URL-safe name, distinct from its title/displayName and from its machine manifest id. Use this to give an app a different public URL. Titles and slugs are independent: editing the title with update_app does not change the slug; this tool does. Renaming changes the public URL, and the old URL keeps working by redirecting to the new one. Slug rules: lowercase letters, digits, and hyphens; 2-48 chars; may start with a letter or digit; no leading, trailing, or consecutive hyphens. When telling the user where to open or share the renamed app, always give them `shareUrl` from the result — never the `url` field, which is machine-only and embeds a write-capable access token.",
