What it does

When installed, the agent can produce a cover image by running the KrillinAI command-line tool with a complete text prompt you or the agent write, then sending that prompt to a configured image-generation model. It checks that the result is a valid, non-empty image and that the saved prompt matches what was submitted, and it reports errors instead of assuming success. The skill does not add creative judgment about the title or layout; the prompt must already contain the title text, language, composition and style.

Great for

  • Video creators using KrillinAI who want a matching thumbnail or cover generated from a prepared prompt
  • Developers automating cover creation inside a KrillinAI task workflow
  • Users who already have an image-model API configured in KrillinAI and want a repeatable command

Skip it if

  • People without KrillinAI installed and configured: the skill depends on its CLI and config file, and will fail without them
  • Workflows needing the source video's cover used as a reference image: the CLI does not send origin_cover.jpg to the model, so results will not reflect it unless described in the prompt
  • Users expecting it to write the title or design the cover themselves: it only executes a supplied prompt

Try asking

  • “Generate a 1536x1024 cover for my video using the prompt I wrote, saving to the current task folder”
  • “Run a dry run first to check that the cover command and config are valid before spending image-model credits”
  • “Create a cover from this prompt and show me the generated image path and saved final prompt”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Put the exact title text, language, composition and style directly in the prompt, since the tool will not add them
  • Run with --dry-run first to validate configuration without calling the image model
  • Check that the returned JSON has ok set to true and that generated_cover.png opens as an image before treating the job as done
