prompt-to-asset
Routes one brief to the right image model across 60+ (gpt-image-1.5, Ideogram 3, Recraft V4, Flux), validates the output, and fans out to iOS/Android/PWA/favicon/visionOS/Flutter bundles. Works without an API key via Pollinations, HF Inference, Stable Horde, or host-LLM inline SVG.

Highlights
- Three execution modes —
inline_svg(host LLM authors SVG),external_prompt_only(paste into any web UI),api(server calls the routed provider). Pick what fits. All three finish on $0. - 60+ models, one router — gpt-image-1.5, Ideogram 3 Turbo, Recraft V4, Flux.2, Nano Banana Pro, Imagen 4, SDXL/SD3, plus free-tier Pollinations / HF / Horde / Cloudflare. Each rule cites a research source.
- Refuses to do the wrong thing — the
Nevercolumn. No wordmarks past 3 words through a diffusion sampler. No transparent PNG through Imagen. Nonegative_prompton Flux. - Offline platform fan-out — one 1024² master → iOS AppIconSet, Android adaptive + monochrome, PWA 192/512/512-maskable, favicon bundle, visionOS parallax, Flutter launcher. Zero network.
- Validates before shipping — tier-0 checks on every output: dims, alpha presence, checkerboard FFT, safe-zone bbox, ΔE2000 palette drift, WCAG contrast, OCR Levenshtein on wordmarks.
- Sprite sheets + 9-slice — pack PNG frames into TexturePacker-compatible atlases (Phaser, PixiJS, Godot, Unity); emit 9-slice numbers + CSS
border-image+ Android.9.png.

Usage
You just talk to your assistant. Example from a new chat:
Make me a transparent logo for a developer-tools company called Forge. Flat vector, two-tone warm orange on neutral.
Behind the scenes:
asset_doctor()— check what modes and providers are live.asset_init_brand({ app_name: "Forge", palette: ["#EA580C", "#F5F5F4"] })if nobrand.jsonexists.asset_enhance_prompt({ brief })returns anAssetSpec: classification, rewritten prompt,modes_available[], optionalsvg_brief, optionalpaste_targets, and arouting_tracepointing at the research file that backed the decision (plusnever_models— why Imagen or DALL·E got rejected).- Assistant offers you
inline_svg/external_prompt_only/api. - If
inline_svg: it writes<svg>inline and callsasset_save_inline_svg→ writesmaster.svg,favicon.ico, apple-touch, AppIconSet, PWA bundle to disk. - If
external_prompt_only: assistant shows the refined prompt and the best paste target (free first). You generate, save, then say "ingest this file" →asset_ingest_external. - If
api: assistant calls the routed provider. Server mattes, vectorizes, exports, validates. - Follow-up: "also fan this out for iOS and Android" →
asset_export_bundlewith the saved master.
Zero CLI typing. The CLI is still first-class for CI, shell scripts, and non-MCP environments — both surfaces hit the same core.
Why this exists
Two facts shape everything here.
Producing production-grade software assets is a routing and post-processing problem, not a prompt-engineering problem.
Imagen 3/4 and Gemini Flash Image can't produce real RGBA PNGs — their VAE is RGB-only, so asking for a transparent background renders the grey-and-white checkerboard as pixels. SDXL can't spell past ~8 characters. Only Recraft emits native SVG. Flux errors on negative_prompt. None of that is visible in the model UI. All of it silently breaks one-shot "prompt → asset" tools.
You may not have an image-model API key. The plugin works anyway.
Every one of the three modes can finish on $0.
The three modes
flowchart LR
A["one-line brief"] --> B["asset_enhance_prompt"]
B --> C{"mode"}
C -->|inline_svg| D["Host LLM emits SVG inline<br/>→ asset_save_inline_svg"]

G --> H["AssetBundle<br/>ios · android · pwa · favicon · visionos · flutter"]
| Mode | Key? | What happens | Best for |
|---|---|---|---|
inline_svg |
No | Server returns an SVG-authoring brief (viewBox, palette, path budget ≤ 40). Host LLM emits <svg>…</svg> inline, then asset_save_inline_svg writes master + favicon.ico + apple-touch + AppIconSet + PWA bundle. Instant. Deterministic. |
Logos, favicons, icon packs, stickers, simple app-icon masters |
external_prompt_only |
No | Server returns the dialect-correct prompt plus a ranked list of paste targets, free paths first: Pollinations, HF Inference, Stable Horde, Google AI Studio, Ideogram, Recraft, Midjourney, fal.ai, BFL, ChatGPT, Firefly, Krea. Generate elsewhere, save locally, call asset_ingest_external. |
Anything — best for illustrations, heroes, text-heavy logos |
api |
Optional | Server calls the provider directly. Works zero-key via Pollinations / Horde / HF, or with paid keys. Route → generate → matte → vectorize → export → validate → content-addressed bundle. | Automation, CI, no rate-limit tolerance |
The host LLM picks the mode, or you do. The server surfaces modes_available so the assistant offers them to you. Free paths first — always.
The router
Router decisions live in data/routing-table.json. Capability matrix in data/model-registry.json. Every rule cites its research source.
| Need | Primary | Fallback | Never |
|---|---|---|---|
| Transparent PNG mark | gpt-image-1.5 with background:"transparent" |
Ideogram 3 Turbo (/generate-transparent) → Recraft V4 |
Imagen, Gemini Flash Image, SD 1.5 |
| Logo with 1–3 word text | Ideogram 3 Turbo → gpt-image-1.5 → Recraft V4 |
Composite SVG type over mark | Imagen, SD 1.5, flux-schnell |
| Logo with >3 word text | Never a diffusion sampler. Mark + SVG typography composite. | — | — |
| Native SVG | Recraft V4 (V3 for brand-style pipelines) | inline_svg (host LLM authors SVG) |
Everyone else |
| Photoreal hero | Flux Pro / Flux.2 → gpt-image-1.5 → Gemini 2.5 Flash Image |
SDXL + brand LoRA | DALL·E 3, Imagen 4 (deprecated) |
| Iterate an existing mark | flux-kontext-pro (edit-only) |
Pollinations Kontext (free) | — |
| Zero-key everything | Pollinations (Flux) → inline_svg |
Stable Horde → HF Inference → paste-only | — |
The Never column matters. It's why prompt-to-asset refuses to render wordmarks past 3 words in any diffusion sampler, and why asking for a transparent PNG never goes to Imagen.

Content-addressed storage: assets/<hash[0:2]>/<hash>/<variant>.<ext>. The MCP server is synchronous and stateless. prompt_hash and params_hash in every AssetBundle are designed to drop straight into a BullMQ / SQS / Cloudflare Queues jobId for a hosted pipeline.

Design thesis
You own the API keys. The LLM owns everything else.
The only thing that happens in a terminal is installing the package and putting keys in .env. Secrets shouldn't pass through chat. Every other verb — doctor checks, model inspection, platform fan-out, brand scaffolding, sprite sheets, 9-slice configs — is an MCP tool the assistant calls when you ask in natural language.

Security
This tool handles API keys for up to 15 providers. Non-negotiables:
- Keys live in env vars only. Never written to disk, never logged, never echoed in MCP responses. Provider error bodies go through
redact()(packages/mcp-server/src/security/redact.ts) before reaching the host LLM. - Path access is allow-listed.
image_path/output_dir/existing_mark_svgresolve through symlinks and reject anything escaping project cwd + configured output dir + cache dir + OS tempdir. Widen withP2A_ALLOWED_PATHS=/path1:/path2. - SVG is XSS-sanitized before any write.
<script>,<foreignObject>,on*=handlers,javascript:URIs, external<image href>/<use href>, CSS@importover the network — all rejected. The check runs unconditionally; SVGO is not required. - Cost guardrail. Set
P2A_MAX_SPEND_USD_PER_RUN=5.00to cap any single tool call. Pre-flight estimate refuses to call if over. Free-tier routes are always $0. - Data integrity at boot.
assertDataIntegrityAtBoot()runs on start. If a routing rule points at a model id not in the registry, the server refuses to boot with a clear error. Check in CI withp2a doctor --data. - No telemetry. No remote calls unless the routed provider explicitly requires one.
Full policy: SECURITY.md.
Research-backed decisions
Every routing rule, dialect switch, safe-zone size, and text ceiling that's implemented is backed by a file under docs/research/. asset_enhance_prompt returns a routing_trace.research_sources array on every call. The angle → code pointer map, plus an honest ledger of what's wired and what's deferred, lives in docs/RESEARCH_MAP.md.
Development
git clone https://github.com/MohamedAbdallah-14/prompt-to-asset.git
cd prompt-to-asset
npm install
npm run build
npm run typecheck
npm run lint
npm test # vitest watch
npm run test:run # vitest run (CI)
npm run smoke # list tools via MCP stdio + correctness assertions
npm run sync # regenerate IDE mirrors from SSOTs
npm run verify # byte-verify mirrors match SSOTs
SSOTs live in skills/*/SKILL.md, rules/*.md, .claude-plugin/, and data/*.json. Don't edit .cursor/, .claude/, .windsurf/ directly — they're regenerated by scripts/sync-mirrors.sh and CI byte-verifies them.
