Spec-Driven Development With Claude Code And Cursor
Spec-driven development keeps Claude Code, Cursor, and other AI coding tools aligned by giving them stable project rules before code generation starts.
Start with a spec, not a chat
Spec-driven development means the architecture is written down before an AI assistant starts changing files. The spec names the stack, services, routing rules, persistence layer, and deployment constraints.
This changes the role of Claude Code and Cursor. They stop acting as system designers by accident and become implementation tools working inside known boundaries.
Keep local assistants narrow
AI coding tools are strongest when the task is concrete. A narrow request like "add this route using the existing Fastify pattern" is easier to verify than a broad request like "build the backend".
Logic64 turns broad product intent into governed workspace context first. After that, local tools can edit inside the generated structure with much less architectural drift.
Use validation as the handoff
The handoff from planning to coding should not be trust based. Generated files need schemas, routing rules, and consistency checks before they become the source of truth.
When a spec and validation layer exist, Claude Code and Cursor can move faster because the project already knows what a correct change should look like.
