Reverse engineer the repo. Build the product.
Build Pack turns a repository into a build-from-scratch execution spec: goals, MVP scope, entities, routes, modules, phases, first builds, non-goals, and risks. It also includes a derived Cursor Pack for phased implementation prompts.
Pro · larger monthly credit pool · private repos supported
How it works
Three steps, one output.
Analyze the repo as a product system
Generate the execution blueprint
Use the derived Cursor Pack
What you get
An editable document, not a checklist.
Product thesis and MVP scope
What product this repo represents, who it is for, and what the first real version should include.
Entities, routes, and modules
The likely data model, pages/flows, and backend modules needed to rebuild the product from scratch.
Implementation phases
A staged build sequence with deliverables and exit criteria instead of a giant undifferentiated backlog.
Cursor Pack
Master context plus phased prompts for foundation, core flows, polish, deployment, and bugfix work.
Who this is for
Built for the people who ship.
Founders rebuilding from a proven pattern
You want the architecture and product logic of a strong repo without treating that repo as your codebase destination.
AI-assisted builders
You need a build plan and prompt system that encourages inspection, phasing, and maintainability.
Teams planning a greenfield implementation
Use Build Pack as the spine for a serious rebuild spec before the first tickets are written.
Operators coordinating product and engineering
It gives both sides a shared map of what to build first and what to defer.
