| description | Create a cover image for an existing draft. Wraps `postall-agent image`. Activates when the user wish references a draft and asks for "a cover image", "add a picture", or comes right after a generate-content step in a publishing pipeline. |
Generate a cover image for an existing draft using PostAll's image executor.
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.
postall-agent image --draft "<DRAFT_ID>" [--prompt "<PROMPT>"]
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.
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.
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.
Generate draft text for one or more social platforms from a topic or URL. Wraps `postall-agent generate`. Activates when the user wish includes a content topic plus a publishing intent ("write a tweet about X", "draft a LinkedIn post on Y", "summarize this URL into a wechat article").
List recent content drafts. Wraps `postall-agent list`. Activates when the user wish is read-only — "what drafts do I have", "show me unpublished posts", "any pending content".
Publish an existing draft to one or more platform accounts. Wraps `postall-agent publish`. Activates when the user wish says "publish", "send it out", "post to LinkedIn", or comes at the end of a publishing pipeline.
Echo the user's input back verbatim. Useful for greetings, smoke tests, or any wish that's purely conversational and doesn't need data fetching or analysis. Activates when the user says "echo X", "hi", "hello", or similar.
Fetch a URL and produce a concise one-paragraph summary. Activates when the user wish contains a URL or asks to "summarize", "read", "fetch", or "tell me what this page says about" a webpage.
