Overview

OpenSpec introduces an artifact-guided workflow for spec-driven development, emphasizing alignment between humans and AI before code implementation. Unlike rigid phase-gate methodologies, OpenSpec allows fluid updates to any artifact (proposals, specs, designs, tasks) at any time, maintaining organization through dedicated change folders. Each feature or modification gets its own structured workspace, enabling teams to stay organized while preserving flexibility in how they approach specification and implementation.

The Verdict

Who Should Use OpenSpec?

Best For

  • Teams wanting spec-driven dev without rigid waterfall constraints
  • Projects requiring both structure and flexibility in workflows
  • AI-assisted development with clear human oversight

Not Ideal For

  • Teams preferring strict phase-gate approval processes
  • Projects where informal communication suffices over documentation

What's Great

  • Fluid artifact updates without phase gates
  • Ensures human-AI alignment before building
  • Organized folder structure per change
  • Balances structure with workflow flexibility
  • Clear artifact types (proposals, specs, designs, tasks)
