Woolen — AI Prompt Context Platform
AICPS: structured prompts and context for real-world AI workflows.
Fox Hill Lab — AI Infrastructure, SaaS Platform
Overview
Woolen is Fox Hill’s internal AI Prompt Context Platform (AICPS). It’s designed to give teams a consistent way to build, version, and deploy AI-powered workflows without burying business logic inside ad-hoc prompts scattered across repos and Google Docs.
Challenge
As teams adopt AI, they quickly run into the same problems: prompt sprawl, inconsistent behavior between environments, lack of transparency, and no clear place to configure context, boundaries, or model choices. We wanted to see what a ‘prompt operating system’ might look like.
Solution
- Modular prompt objects that can be reused, versioned, and composed.
- Context providers that pull in relevant data (e.g., user, session, MCP connections) at request time.
- Three layers of configuration: user defaults, session defaults, and per-request overrides.
- A ‘model’ property that lets each request target different underlying models while keeping business logic intact.
- Streaming support via SSE/WebSocket for responsive UX.
- A roadmap for multi-tenant SaaS with encrypted logging and scoped access.
Impact
Woolen shows how Fox Hill approaches AI not as a gimmick, but as infrastructure. It’s a concrete example of our ability to design APIs, data models, and operational patterns that enterprises can trust in production.
