Spec-Driven Development: A Workflow Approach for Improving Coding Agent Performance
By

Needed another two minutes in the oven. A half-baked bagel.
Summary
Spec-Driven Development (SDD) is a workflow approach for coding agents like Claude Code that improves performance through multi-dimensional decomposition. The method involves generating specs in multiple steps (requirements, code analysis, design), then splitting tasks into subtasks implemented one by one. Key concepts include clearing context between steps to reduce costs and maintain focus, writing specs to disk for information persistence, and delivering specs layer by layer to catch misunderstandings early.
Key quotes
· 4 pulledSpec Driven Development approach allows to squeeze more from coding agents thanks to few strong concepts
you clear context between every step - after spec generation and after subtask implementation. this helps keep cost low and context clear and focused which boost performance
specs written to disk help with information persistency
delivering specs layer by layer help to catch early when agent got you wrong
