# Stop Building Features Based on Assumptions **Spec Iterator** conducts structured AI-powered clarification sessions that systematically uncover gaps in your requirements *before* you write code. --- ## The Problem Everyone Ignores ``` Stakeholder: "Build a dashboard for our sales team" โ You build it โ Stakeholder: "Where's the pipeline view?" โ You: "You didn't mention that" โ Stakeholder: "I assumed it was obvious" โ ๐ธ 2 weeks of rework ``` **Requirements arrive incomplete.** Stakeholders don't know what they don't know. The "obvious" features only become obvious after you ship the wrong thing. --- ## How Spec Iterator Works ``` โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ โ "We need order tracking for customers" โ โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ โ โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ โ ๐ ANALYZE โ โ โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ โ โ โข Entities detected: orders, customers, tracking โ โ โข Gaps found: users undefined, stages unclear, no UX โ โ โข Completeness: 12% โ โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ โ โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ โ โ CLARIFY (Round 1) โ โ โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ โ โ 1.
