Image Asset Pipeline (Limner)
Autonomous multi-tool pipeline producing 500+ uniformly stylized assets with zero human intervention
Published:
Context
Needed to produce consistent, scalable visual assets — game sprites, UI elements, icons, and print-resolution portraits. No single AI tool handles the full pipeline from concept to production-ready output. Each tool excels at one stage but produces inconsistent results when used alone at scale.
Approach
Designed a multi-stage production pipeline with explicit handoff points and autonomous quality control:
- Stage 1: MidJourney for concept exploration and high-fidelity starting images
- Stage 2: PixelLab (via custom “Limner” agent) for pixel art conversion and bulk generation
- Stage 3: Automated quality gating — non-conforming outputs rejected before delivery
- Stage 4: Vectorization for scalable, print-ready output at any resolution
Built the Limner agent as a dedicated pixel art specialist with trained workflows for consistent style enforcement across batches.
Outcome
Production pipeline capable of generating consistent asset sets at any scale. Multiple batches of 500+ uniformly stylized assets produced autonomously with zero human intervention required. Successfully applied to: game assets (VGA-era pixel art), UI elements, icon sets, and vanity portraiture at print resolution.
Key Insight
The value is in designing handoff points between tools, not in mastering individual tools. The orchestration layer — deciding what goes where, what quality looks like, and what gets rejected — is the PM skill.
Portfolio Signal
- ◈ Multi-tool workflow design with defined handoff points
- ◈ Autonomous production orchestration (500+ assets, zero intervention)
- ◈ Quality gating as a design decision, not an afterthought
- ◈ Custom agent development for specialized production roles
Corporate Translation
This is vendor orchestration. Different tools have different strengths, different costs, different failure modes. The pipeline design — not any single tool — is what produces consistent output at scale. Same skill as managing a multi-vendor engineering program.
