Show HN: Spec-Driven Development Workflow for Claude Code

Spec-Driven Development workflow for coding agents like Claude, which improves performance by decomposing tasks across two dimensions: first generating multi-step specs (requirements, code analysis, design), then splitting implementation into subtasks. Key benefits 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. A GitHub repository with a Claude plugin for this workflow is provided.

Spec Driven Development approach allows to squeeze more from coding agents thanks to few strong concepts:

  • decomposition across two dimensions. first you generate specs in multiple steps (requirements, code analysis, design), than you split task into multiple subtasks and implement them one by one
  • 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 Repo with claude plugin for spec driven development: https://github.com/sermakarevich/sddw
