Avatar Maker

Distinct from flyer-maker / carousel-builder:

• Single subject focus (the face). No event details, no narrative split, no embedded text.
• Identity preserve is the PRIMARY constraint — model picker defaults to nano-banana-pro.
• Multi-variant within an aspect is the common case (give user 3 takes per aspect, pick the best).

This skill does NOT:

• Generate avatars from text alone — --photo is required (use image-prompt for text-only portrait generation).
• Render text overlays (name / handle / title) — avatars are visual only. Add text in your design tool if needed.
• Touch-up / retouch existing photos at the pixel level — the model regenerates the subject in a new style.
• Generate animal mascots / cartoon avatars without a photo reference — see image-prompt for that.
• Handle multi-person group photos — single subject only; the model picks one face if given a group.

ROLE

Read user photo + optional style preference → pick a ref-capable identity-preserving model → assemble per-aspect prompts emphasizing identity preserve + style anchor → batch execute → save N variants per aspect → print paths.

PIPELINE

1. Resolve photo (required):

   • --photo <path-or-url>: local file or remote URL.
   • Should be a clean front-facing portrait at ≥800px on the short edge for best results.

2. Resolve style:

   • --style auto: picks photoreal-friendly styles from carousel library (kinfolk-minimal, photo-editorial-bw, gradient-mesh-modern, dark-academia, …) — avoids illustration / 3D styles where identity gets lost.
   • --style <library-id>: explicit library entry. Uses the Style anchor (carousel) block.
   • --style-mod "<override>": tweak.

3. Pick model:

   • --model auto: defaults to nano-banana-pro (best identity preserve).
     • If identity preserve isn't the priority (style transfer first) → flux-2-pro or seedream-5.
     • If embedded brand colors / typography needed → ideogram-3 (rare for avatars).
   • --model <slug>: override.
   • ONE model across all aspects + variants.

4. Build per-aspect prompts:

   <style anchor (carousel)>
   
   Portrait of the person from the reference image. Preserve identity: face shape, age, ethnicity, hair, distinguishing features. Apply the style's palette, lighting, and composition to the surrounding environment / clothing texture / background — but the face stays recognizably the same person.
   
   Framing: <aspect-specific>
   Aspect ratio: <ratio>
   Size: <pixel dimensions>
   

5. Estimate cost + confirm — aspects × variants × per-image cost. Default 1 aspect × 3 variants × $0.05 = $0.15. Under budget.

6. Batch execute — common.runners.batch.run_batch(). Parallelism 3.

7. Output:

   ./generated/avatar/<slug>/
     square-v1.png ... square-v<N>.png   (1080×1080)
     cover-v1.png ... cover-v<N>.png      (1080×1350, if requested)
     story-v1.png ... story-v<N>.png      (1080×1920, if requested)
     manifest.json
     style-used.md
     prompts.md
   

MODES

Required

• avatar-maker --photo <path-or-url>

Style

• --style auto|<library-id> — visual style (default: auto, picks photoreal-friendly)
• --style-mod "<override>" — tweak the anchor

Aspect + variants

• --aspects square,square-tight,cover,story — comma list (default: square)
• --variants N — variants per aspect (default 3 — sweet spot for picking the best)
• --slug <name> — output directory slug (default: derived from photo filename)

Execution

• --model auto|<slug> — image provider (default nano-banana-pro)
• --execute — actually generate (else returns prompts)
• --output <dir> — custom output dir
• --parallelism N — concurrent API calls (default 3)
• --yes — skip cost confirmation
• --resume — retry failed variants
• --prompts-only — dry run, save prompts.md, exit
• --cost-only — print total cost, exit
• --strict — exit if --model <slug> can't handle photo refs

EXAMPLES

See examples/before-after.md — 3 calibration runs: founder headshot for LinkedIn (kinfolk-minimal, 3 variants), photo-editorial B&W portrait set, multi-aspect avatar set for someone setting up new social accounts (square + cover-banner + story).

CONSTRAINTS

• Identity preserve is paramount. Nano Banana Pro is the safest pick. If --model is overridden and identity gets lost, the troubleshoot reference covers fixes.

• Use a clean source photo. ≥800px on the short edge. Front-facing or 3/4. Even lighting. Avoid heavy shadow / backlight / partial occlusion.

• No mid-image text. Avatars are visual-only. Don't add --title or similar.

• Default 3 variants per aspect. Models produce stochastic variation — 3 takes lets the user pick the best. Past 5, diminishing returns.

• One model across the run. Mixing providers breaks consistency.

• One style across the run. Same anchor across all aspects + variants.

• Photoreal-friendly styles win. Carousel library has illustration / 3D / abstract styles (flat-vector-illustration, low-poly-3d, paper-cutout-craft) — these LOSE identity. --style auto filters them out. If explicitly chosen, the result will look more like "a person in that style" than "this specific person".

• Cost confirm ONCE per batch. Sum across aspects × variants.

• Output slug derived from photo filename by default. Override via --slug or --output.

• Manifest updates after every variant. --resume retries failed only.

• Photo can be local or URL. Provider routes accordingly.

• Never print API keys. Mask in errors.

• Output dir is ./generated/avatar/<slug>/ by default.

INVOCATION HINTS

When the user says any of:

• "make me an avatar / profile pic from this photo"
• "headshot variants", "portrait variants"
• "LinkedIn profile picture", "Twitter profile pic", "Instagram avatar"
• "professional headshot", "business portrait"
• "branded avatar set" (variants in different aspects for cross-platform consistency)
• "сделай аватарку / портрет / хедшот"
• "профиль для LinkedIn / Twitter / IG"
• "аватарка с моей фоткой"

Defaults: --aspects square --variants 3 --style auto --model nano-banana-pro. Without --execute, returns prompts; with --execute, generates.

If the user mentions LinkedIn → emphasize --aspects square (LinkedIn profile is 1:1 + a 4:1 cover-banner area; the cover aspect is closer to LinkedIn cover banner).

If the user mentions cross-platform: --aspects square,square-tight,cover gives them 1:1 for most + a tighter crop for small profile thumbs + a cover banner.

This skill is distinct from:

• flyer-maker — that's events with embedded text; this is identity-preserved portraits
• image-prompt — that's any image; this is specifically photo-input → variant portraits
• carousel-builder — that's narrative slides; this is variants of one subject
