About this capability

Use when generating a cover image with the KrillinAI CLI from a complete image prompt, including validating image-provider configuration and inspecting the generated image and saved prompt.

What this skill tells your AI

The instructions your AI receives, as published by krillinai/opencreator in skills/krillinai-cover/SKILL.md and read by ahel’s review.

Use this skill for the implemented cover command. Read skills/krillinai-cli/references/cli-contract.md first for binary location, execution working directory, configuration, and JSON behavior.

Command

(cd "$KRILLINAI_CWD" && "$KRILLINAI_CLI" cover \
  --workdir "$WORKDIR" \
  --prompt "$COVER_PROMPT" \
  --size 1536x1024)

The prompt must already contain the desired title text, language, composition, visual style, and any useful source-video context. The current CLI does not expose a reference-image argument and does not automatically send origin_cover.jpg to the image model.

Inputs

  • --workdir: an existing or new task directory.
  • --prompt: required final prompt sent to the configured image model.
  • --size: optional image size; the default is 1024x1024.
  • [image] configuration in <execution-cwd>/config/config.toml.

Outputs

  • generated_cover.png
  • cover_prompt.final.txt
  • krillinai_manifest.json

Dry Run

cover --dry-run validates the command and writes a manifest, but it does not call the image model or create generated_cover.png.

Verification

  • Require terminal JSON with "ok": true.
  • Read output paths from the terminal response or manifest.
  • Confirm generated_cover.png is non-empty and decodable as an image.
  • Confirm cover_prompt.final.txt exactly records the submitted prompt.
  • If provider configuration is missing or generation fails, report the returned error rather than treating the manifest alone as success.
