Image prompt

image-prompt

Turn a one-line idea into a single, gold-quality image-generation prompt. Auto-first: infer everything sensible, output the prompt, let the user redirect in one line.

Workflow

1. Read the idea. Extract: subject/brand, any style hints, aspect/format, target model. Invent a fictional placeholder brand name if branding is implied but none given. If the user names a saved style ("in the <name> style", "use preset <name>") or asks to save one ("save this style as <name>"), handle it via Style presets below. If the user wants help choosing a look ("help me with the style", "what styles can you do", "в каких стилях можешь"), present the Style menu below. If the user supplies an existing image to transform, composite, restyle, localize, or place someone/something into — or wants a poster/ad built around a supplied person or product — that is an EDIT: use Edit / remix mode below.

2. Pick the archetype using references/archetypes.md (poster / landing-hero / product-ad / ui-mockup / photoreal-scene / game-screenshot / infographic / logo / illustration). Use the routing table. If ambiguous, choose the richest layout and note it.

3. Set defaults from the archetype: aspect → size, quality. (See the model adapter.)

4. Expand into the 9-block skeleton using references/anatomy.md. Skim the matching gold example(s) in references/gold-examples.md to calibrate depth and phrasing. Pull fonts + a cohesive hex palette from references/fonts-palettes.md. Fill every block: named zones with position/size%/tilt, literal copy in quotes, named fonts, hex palette, mood cluster, finish + quality tag. Photoreal/game ideas use the labeled-block variant.

5. Format for the target model. Default gpt-image-2 → follow references/models/gpt-image-2.md (labeled sections, text-in-quotes, CONSTRAINTS block, size/quality). If the user names another model and its file doesn't exist yet, say so and fall back to the rich natural-language style, then proceed.

6. Output (see format below): the finished prompt in its own fenced code block, then a one-line assumptions/knobs note underneath.

Auto-first — do NOT interrogate

Produce a full prompt on the first turn. Only ask one question if the idea is truly unworkable (e.g. no discernible subject at all). Everything else — archetype, aspect, palette, brand name, copy — you infer and surface in the assumptions line so the user can correct with a single sentence ("make it 9:16", "darker palette", "brand is NOVA").

Model handling

Default target: gpt-image-2. When the user names a model, load its adapter and follow it — the 9-block content stays the same; only the rendering (output shape, params/flags, size/ratio) changes.

Model (match loosely, incl. RU)	Adapter
gpt-image-2 (default), gpt-image-1, gpt-image-1.5, "openai"	references/models/gpt-image-2.md
nano banana pro, gemini 3 pro image, "gemini", "нанобанана"	references/models/gemini.md
midjourney, "mj", "миджорни"	references/models/midjourney.md
flux, flux.2	references/models/flux.md
ideogram	references/models/ideogram.md
recraft	references/models/recraft.md
reve	references/models/reve.md
universal / unknown tool	references/models/universal.md

If the user names a model with no adapter yet, use universal and say so. Pick by fit when the user is unsure: text-heavy / infographic / factual → gemini (Nano Banana Pro) or gpt-image-2; brand / typography / vector / logo → recraft; pure aesthetics → midjourney; open-weight / local / hex control → flux; strong prompt-adherence + layout editing → reve; unknown tool or "just a great prompt" → universal.

Style presets (user-local, private)

Presets are saved styles (never content) the user has dialed in, stored per-user at ~/.claude/image-prompt/presets/<name>.md — NOT in this repo, never committed, private to the machine. Create the directory on first save. Each user grows their own set.

• Save — on "save this style as <name>" / "запомни этот стиль как …": distill ONLY the style layer (never subject, copy, or specific zones). Capture the distinctive signatures that make the style non-generic — palette + fonts alone flatten the output. Nail: MEDIUM/technique (watercolor vs flat vector vs risograph vs 3D render vs photo), how and WHERE fills are painted (flat vs mottled/grainy; applied globally vs confined to specific accent elements — apply a texture where the reference uses it, not everywhere), LINE quality (loose/varied vs clean/even), COMPOSITION rhythm (sparse/airy vs dense; organic vs grid; negative space), and an explicit AVOID list of anti-patterns that would drift toward a generic look. When deriving from reference images, name the 2-3 traits that separate this style from a generic version and encode them; if refs are available, sanity-check the intended output against them. A big AI-tell is the model's own default "polished illustration" look — soft digital watercolor gradients, airbrushed bleed, over-clean vector lines, glossy 3D; name these in AVOID and prefer flat color + real (grain/halftone/print) texture + restraint. Do NOT over-stack texture adjectives, which can trigger that exact generic look. Write the file (format below), then confirm what was captured.
• Use — on "in the <name> style" / "use preset <name>": read the preset, build the CONTENT from the new idea as usual, but take background/texture, palette, fonts, motifs, mood, and finish from the preset (overriding the archetype's style defaults). Keep the preset's model. If no preset by that name exists, say so and list what's available.
• Manage — "list my presets" (read the dir), "update <name>", "delete <name>".

Preset file format:

---
name: <kebab-name>
description: <one line>
suits: [poster, landing-hero, illustration, ...]
model: gpt-image-2
---
MEDIUM: <what it physically is + technique — watercolor illustration / flat vector / risograph / 3D render / photo>
BACKGROUND: <bg + global texture, with hex>
PALETTE: <hex codes + HOW fills are painted (flat? mottled watercolor? grain showing through?)>
LINE: <stroke quality if line-based — loose/varied vs clean/even> (omit if not line-art)
FONTS: <named fonts + roles + effects>
MOTIFS: <signature graphic devices>
COMPOSITION: <density & rhythm — sparse/airy vs dense; organic vs grid; negative space>
MOOD: <adjective cluster>
FINISH: <texture / post-processing>
AVOID: <anti-patterns that would drift toward a generic look>
CONSTRAINTS: <IP-safety etc.>

Older presets may omit MEDIUM / LINE / COMPOSITION / AVOID — add them when updating a preset that renders too "generic".

Sharing presets (preset codes)

Presets are portable: export one to a self-contained code anyone can import — no hosting, no accounts. Format: imgpreset:v1:<b64> where <b64> is base64 of gzip of the preset file's UTF-8 bytes (verified round-trip).

• Export — on "export preset <name>": encode ~/.claude/image-prompt/presets/<name>.md and print the code in its own copy block. Reference command (P = the preset path): python3 -c "import gzip,base64;print('imgpreset:v1:'+base64.b64encode(gzip.compress(open('$P','rb').read())).decode())" Any equivalent gzip+base64 tool works; keep the imgpreset:v1: prefix. Also try to copy the code straight to the system clipboard when a tool is present (pbcopy on macOS, wl-copy or xclip -selection clipboard on Linux) and tell the user it's copied — but always print the block too, so Claude Code's built-in copy works as a fallback.
• Import — on "import preset imgpreset:v1:…": decode the payload after the prefix, gunzip it, read name: from the decoded frontmatter, and write presets/<name>.md. Confirm what landed; if a preset with that name already exists, ask before overwriting. Reference command (OUT = target path, C = the code): python3 -c "import sys,gzip,base64;open('$OUT','wb').write(gzip.decompress(base64.b64decode('$C'.split(':',2)[2])))"
• Validate after import: the decoded file must start with --- frontmatter and contain a name: line. Reject anything that doesn't decode to a valid preset.

Reference-library presets

A preset can also be a reference library (type: reference-library in its frontmatter): instead of one style it holds many distilled reference cards plus a pointer to source images (e.g. ~/.claude/image-prompt/references/<name>/). When the user invokes it ("use my ui references", "по моей ui-базе"): read the cards, propose the 2-3 that best fit the project (the user can swap or add — offer, don't lock), then compose the mockup from those, favouring what fits the project over any single house style. To ingest new screenshots dropped into the source folder: view each image, append a card (template inside the library file), and refresh the aggregated-patterns summary. Libraries are user-local and private — never committed.

Style menu (help me choose a look)

When the user knows the deliverable but wants help with the style ("help me with the style", "what styles can you do", "в каких стилях можешь"), present the built-in repertoire from references/styles.md: show names + one-line vibes, grouped, and offer the user's own private presets alongside. Let them pick one or combine two, then build using that style's spec (it fills the style layer; content comes from the idea). Offer to save the result as a preset. Keep the on-screen menu short — pull a style's full spec only once it's chosen.

Edit / remix mode

When the user gives an existing image (or refers to one) and wants to transform / composite / restyle / localize it, or build a poster/ad around a supplied person or product, this is an edit, not a generate. Follow references/edit-remix.md: pick the matching workflow and build the prompt with the change-vs-preserve framing (state what changes, list the invariants, repeat them), reference each input image by index + role, and set params (input_fidelity=high, background=opaque for product extraction, quality/size to fit). Use the edit template in that file. Still prompt-only — the user attaches the image(s) in their tool. The input_fidelity / background params are gpt-image-2's; for edits targeting another model, use that model's own editing section (Gemini, FLUX, Recraft, Reve each support edits) for its params.

Generate (optional, opt-in)

The skill is prompt-only by default. If the user explicitly asks to generate/render the image AND a provider API key is in the environment, you may run the optional generate step via scripts/generate.py — see references/generation.md. Confirm first that it's a paid API call, then write the prompt to a temp file and run the script, save the PNG into the project, and view it to check. Never generate without an explicit request and a present key; otherwise just deliver the prompt. Midjourney has no API — prompt only.

Output format

Put the prompt in its own fenced code block so the user can copy it in one action. Nothing else inside the block. Then one assumptions line beneath it:

```
<the finished prompt — labeled sections for gpt-image-2>
```
**Assumptions:** archetype=<x> · size=<WxH> · quality=<low|medium|high> · brand=<name> ·
model=gpt-image-2. Change any of these in one line, or say "another variant".

Keep the prompt itself clean and self-contained (no meta-commentary inside it).

Quality bar (non-negotiable)

• Name real fonts for every text role; never "a nice font". Exception: Gemini, Ideogram and Recraft can't consume font names — describe fonts by trait there (per those adapters).
• Give every color a hex code; never a bare color word.
• Break the canvas into named zones with positions — this is the #1 quality signal.
• Include a finish/texture cue (grain, halftone, brushwork, pores) and a quality tag.
• Put all rendered text in quotes; keep it short; render each string once.
• Always add IP-safety: original design, no logos/trademarks/watermark; brand-like glyphs are "generic, not resembling any real brand".

Growing the skill

New favourite prompt → add it to references/gold-examples.md (with a "Teaches:" tag). New model → add references/models/<name>.md; the workflow above stays unchanged.
