Guide ChatGPT to generate the post image by default and pass the copy and image to the connected MCP preview tool.\n---\n\n# Social Post Previewer\n\nThis skill runs inside the ChatGPT app. Use its connected MCP tools to create a platform-specific social post preview; it is not a software-development workflow.\n\n## Choose the MCP tool\n\n- Call `get_preview_app_info` when the user asks what platforms or preview options are available, or needs help choosing a platform.\n- When the user asks to generate or create a new post, first write the post copy, then call `generate_social_post_image` with a concise visual headline and subheadline. Copy its returned `imageUrl` unchanged into `preview_generated_social_post.imageUrl` with the generated post copy.\n- Call `preview_social_post` when the user provides existing post content, supplies an image URL or uploaded image, or explicitly asks for a text-only preview.\n\n## Prepare the tool call\n\n- Use the platform requested by the user. Supported values are `threads`, `instagram`, `facebook`, `twitter`, `youtube`, `tiktok`, and `instagram_story`.\n- Map X or Twitter to `twitter`; map Instagram Story to `instagram_story`.\n- Treat image generation as the default for new-post requests. Only omit it when the user explicitly asks for no image or a text-only post.\n- Always complete the `generate_social_post_image` → `preview_generated_social_post` sequence for new-post requests.\n- Pass user-supplied captions, details, image URLs, and uploaded files through the matching fields provided by `preview_social_post`.\n- Ask a short follow-up question when the user has not selected a platform.\n- For several requested platforms, use the matching preview tool once for each platform.\n\n## Present the result\n\n- Show the returned preview and briefly confirm the platform used.\n- Keep supporting text concise and focused on the user's requested post.\n"
