# Generate Image Skill Generate a cover image for an existing draft using PostAll's image executor. ## Inputs - `draft_id` (required) — the draft to attach the image to. - `prompt` (optional) — override the auto-generated prompt with explicit imagery directions. If `draft_id` is missing, return an error final message immediately. ## Execution ```bash postall-agent image --draft "<DRAFT_ID>" [--prompt "<PROMPT>"] ``` ## Output handling Parse the JSON. Return: - `draft_id` — same as input. - `image_path` — local path to the generated image. Final message: ``` Image generated for draft <ID>. path: <IMAGE_PATH> ``` If the JSON has `success: false`, surface the error verbatim — common causes are billing limit, invalid draft_id, or image executor not configured. ## Composability notes Often called between `generate-content` and `publish-content`. The user profile flag `always_generate_image` (default true) signals whether the planner should auto-insert this skill into publish pipelines. ## Prerequisite Same as `generate-content` — `postall-agent` must be installed. Additionally, the image generation requires a working image executor (Gemini / DALL-E / etc.) configured in the postall environment. If image generation fails with auth or config errors, surface the error and suggest checking the postall configuration.
