Quick Start

# Install
npm install -g @sengac/fspec
 
# Initialize
cd /path/to/your/project
fspec init
Then in Claude Code:
/fspec Build user login feature

Claude will guide you through the ACDD workflow: discover → specify → test → implement.

Already have code?

Use Reverse ACDD to document existing codebases:

  1. Analyze what you have (code? tests? specs?)
  2. Choose a strategy (A, B, C, or D)
  3. Generate missing pieces automatically
  4. Link everything for full traceability

"fspec transformed how we build with AI agents. No more skipping tests or writing code before specs. Our AI follows ACDD workflow religiously now."
