Gpt Image 2

GPT Image 2 — Interactive Image Generation

Generate and edit images via OpenAI's GPT Image 2 API with an interactive, guided workflow.

Interactive Flow

When the user invokes this skill, guide them through these steps using AskUserQuestion. Do not skip steps — the interactive flow is the core experience.

Step 1: What are we making?

Ask the user what they want to create. Offer these options:

• Single image — one image from a text prompt
• Photo edit — transform an existing photo into a style
• Carousel — 5-10 cohesive slides for LinkedIn/Instagram
• Variants — multiple versions of the same concept
• Quick generate — skip questions, just run the prompt

If the user already provided a clear prompt (e.g. "generate an editorial image of a rocket"), skip to Step 3.

Step 2: Style selection

Show the user available presets grouped by category. Read presets.yaml and present them:

Visual styles (no text in image):

editorial, blueprint, ink, risograph, wireframe, constellation, brutalist, grain

Text-heavy (leverages GPT Image 2 text rendering):

infographic, slide, diagram, poster, menu, manga

Community favorites:

trading-card, pixar, app-mockup, isometric, action-figure, cinematic, panorama

Reference-anchored:

vhs — 1980s late-night infomercial title card: scanline-striped gradient italic caps on pure black. It auto-attaches a bundled reference image (references/vhs-infomercial.png), so the look stays consistent batch-to-batch. Pass the ad copy as the subject; for multi-line copy separate lines with / (e.g. --preset vhs "THEY TRUSTED YOU / NOW / PROVE IT").

Custom — user describes their own style

Ask: "Which style? Or describe your own."

Step 3: Platform & sizing

Ask where this will be used:

• YouTube thumbnail (1280×720)
• Instagram square (1080×1080)
• Slides/presentation (1920×1080)
• Blog hero (1200×630)
• X/Twitter (1600×900)
• Story (1080×1920)
• Custom size
• No resize (use API default)

Aspect-ratio caveat: --platform does NOT change the generation size — it generates at the configured size (default 1024×1024) and resizes/stretches afterwards, which distorts non-square targets (e.g. --platform story stretches a square to 1080×1920, cropping the composition's edges). For portrait or landscape compositions, pass the API-native size directly: --size 1024x1536 (portrait) or --size 1536x1024 (landscape).

Preflight false positives: the background-conflict heuristic trips on color words applied to non-background elements (e.g. "off-white text" in a dark-background prompt reads as a second background). If the flagged conflict is spurious, re-run with --force, or rephrase ("pale gray text").

Step 3.5: Preflight prompt check (automatic)

Before any generation spend, the script now composes the final prompt first

(preset + subject + style), then checks it for internal contradictions — most often

a preset that hard-codes something the subject overrides (e.g. the editorial preset

forces *"on pure black background"* while your subject asks for a warm off-white ground).

The check prefers a fast Haiku call via the llm CLI; if Haiku is unavailable (no

llm, no Anthropic credit) it falls back to the configured llm default model, then to a

built-in static heuristic. The resolved prompt and the verdict are printed. **If a conflict

is found, generation is aborted before spending** — fix the prompt or preset and re-run, or

override with --force (generate anyway) or --no-preflight (skip the check). This is what

prevents the "generated on the wrong background, now regenerate" waste.

When composing prompts that set a background/palette, **don't combine a background-fixing

preset (editorial, blueprint, etc.) with a different requested background** — either drop

the preset and specify the full style yourself, or accept the preset's background.

Step 4: Draft first, then final

Always generate a draft first unless the user says "skip draft" or uses --draft false.

• Generate with --draft (quality=low, ~$0.006/image)
• Show the image to the user using the Read tool
• Ask: "Like this direction? I can: (a) generate final quality, (b) adjust the prompt, (c) try a different style, (d) regenerate with a new seed"
• If approved, generate final with --quality high (~$0.21/image)
• Use --seed from the draft to maintain composition when upgrading to final

This draft→final flow saves ~97% on iteration costs.

Step 5: Show result and offer next actions

After generation, always:

• Show the image using the Read tool
• Open it with open <path> for full-resolution preview
• Report the cost
• Offer: "Want to (a) generate variants, (b) edit this further, (c) use as reference for more images, (d) done?"

Carousel Workflow

When the user wants a carousel (5-10 slides):

1. Story arc

Ask: "What's the story? Give me the key message and I'll draft a 10-slide arc."

Then propose a slide-by-slide plan like:

Slide 1: [Cover] — hook headline + hero image
Slide 2: [Problem] — bold statement
Slide 3: [Context] — illustration + explanation
...
Slide 10: [CTA] — call to action with URL

Ask the user to approve or modify the plan.

2. Style consistency

Use the same preset + seed range across all slides. For carousels:

• Pick one visual style for all slides
• Use --seed to lock composition patterns
• Include pagination dots in prompts (e.g., "10 small dots at bottom, third dot highlighted orange")
• Maintain consistent color palette and typography

3. Draft batch

Generate all slides as drafts first ($0.006 × 10 = $0.06 total). Show them all to the user as a contact sheet or one by one. Ask which ones to regenerate or adjust.

4. Final batch

Only generate finals for approved slides. Offer to generate all at once with -y flag.

Photo Edit Workflow

When the user wants to transform a photo:

• Ask for the source image (file path or clipboard)
• For clipboard: save with osascript to a temp file
• Show available styles and ask which to try
• Generate a draft edit first
• Show result, ask if they want adjustments
• Generate final when approved

Use --edit <path> for the API call.

Cost Awareness

Always communicate costs before generating:

| Quality | Per image | 10-slide carousel |

|---------|-----------|-------------------|

| --draft (low) | $0.006 | $0.06 |

| medium | $0.05 | $0.50 |

| high (default) | $0.21 | $2.10 |

| high + thinking | $0.25-0.42 | $2.50-4.20 |

Thinking mode adds 20-100% cost. Only suggest it for text-heavy or complex compositions.

The script auto-confirms when cost < $0.50. Above that, it prompts the user.

Prompt Engineering Tips

When helping users write prompts, apply these patterns:

• Structure: Scene → Subject → Detail → Lighting → Constraint
• Front-load the subject: put the main thing first
• For text in images: quote exact text with single quotes: 'with the headline "Hello World"'
• Character consistency: maintain a 5-tuple: age + appearance + hairstyle + distinctive features + clothing
• Style tags at end: append tags like editorial-magazine, studio-product to converge batches
• Use --seed for iteration: lock composition, vary only the prompt details
