Vision

Alloy is a proposed engineering intent management layer that sits above Foundry and beside Epilogue Tracker. Epilogue Tracker captures product intent (who the system helps and what goals those actors have); Foundry executes engineering work as event-driven formations of task blocks, gates, agents, and traces. Alloy fills the missing layer between them: the explicit, structured expression of Engineering Intent Records.

The central thesis is that product intent says what people need the software to make possible, while engineering intent says what capabilities the codebase and team must retain as the software changes. Alloy models that intent as records of capabilities, threats, expectations, strategies, evidence, and tradeoffs — turning tacit developer judgement into a form that agents, formations, gates, prompt packs, and humans can all use.

Positioned as an engineering intent management system and runtime control plane, Alloy borrows from requirements tools, ADRs, prompt libraries, and workflow engines but has a more specific job: it captures engineering intent from developers and codebases, compiles it into Foundry formation briefs, and carries the resulting guidance into autonomous execution. It does not replace Foundry, Epilogue Tracker, or the design intent system — it complements all three through a clear ownership boundary.

Alloy owns meaning. Foundry owns execution.
