Specification

Code Is Dead. Long Live the Spec: The One File That Will Replace Your Entire Codebase

Code is becoming a disposable byproduct. The real asset is the human-readable specification. By using declarative formats like KDL, developers can shift from writing code to editing specs, letting AI agents deterministically rebuild entire applications from any change. This paradigm could render version control and manual refactoring obsolete.

Stop Treating Specifications Like Separate Documents

Most teams treat specifications as static artifacts that inevitably decay. Instead, embed spec quotes directly into the implementation code, creating a self-verifying, bidirectional link between requirements and execution. This simple practice makes maintenance trivial and coverage checking automatic. No more hunting for where a spec change impacts the codebase.

Your Agile Process Is Broken Because You Stopped Writing Specs

The tech industry wrongly assumed that agility meant abandoning specification, leading to chaotic sprints and technical debt. True agility doesn’t ask you to stop writing specs; it asks you to use them to shorten feedback loops and reveal misunderstandings early. Specification is the shared language that makes fast iteration possible.
