Cover Image Generation (cover-image)

Reference Images (Important)

If you use reference images (image-to-image / series reference / consistency refs):

• Reference images must be public URLs.
• HTTPS is strongly recommended.
• http:// may work but is insecure and can be blocked by some networks.
• Local file paths and data: URLs are not supported by the WeryAI gateway.

This skill turns a vague "make a cover image" request into a stable set of structured decisions instead of starting from scratch every time.

Script:

• scripts/scaffold.ts
• scripts/build-batch.ts

Safety & Scope

• Network: This skill calls the WeryAI gateway over HTTPS (https://api.weryai.com).
• Auth: Uses IMAGE_GEN_API_KEY. The key is never printed. It may be persisted only when you explicitly run npm run setup -- --persist-api-key.
• Reference images: Must be public URLs (https:// recommended). http:// may work but is insecure. Local file paths and data: URLs are rejected.
• No arbitrary shell: The generation runtime does not execute arbitrary shell commands.
• Files written: Output images and optional local config under .image-skills/cover-image/ (project) and/or ~/.image-skills/cover-image/ (home).

Use Cases

• article cover images
• blog headers or hero images
• newsletter covers
• banner-style key visuals
• any single visual that should feel like a cover rather than an infographic or comic

Core Dimensions

Choose these six dimensions, then assemble the prompt:

1. type
2. palette
3. rendering
4. text
5. mood
6. aspect

See references/dimensions.md.

Commands

Workflow

Step 1: Initialize Working Files

Create the working directory:

${BUN_X} {baseDir}/scripts/scaffold.ts \
  --output-dir cover-image/topic-slug \
  --topic "Why Habits Stick" \
  --concept "A repeating loop turning into visible momentum" \
  --type conceptual \
  --palette elegant \
  --rendering editorial \
  --text title-only \
  --mood balanced \
  --aspect 16:9 \
  --lang en

This creates:

• brief.md
• prompts/cover.md

Step 2: Understand the Content

Extract:

• the main theme
• the target reader
• the keywords
• whether the content fits a person, a scene, or an abstract metaphor
• whether title text needs to appear
• the user's language, when it matters for on-canvas text

Step 3: Choose the Dimensions

Default priorities:

• type: conceptual
• palette: elegant
• rendering: editorial or poster
• text: title-only
• mood: balanced
• aspect: 16:9
