dasroot.net Post-Build Playbook: Convert Vibes Into Guarantees — The 'One Prompt to Build, One Day to Fix' Pattern

dasroot.net·medium signal

dasroot.net published a practical post-build checklist for vibe-coded projects, identifying the 'one prompt to build, one day to fix' pattern. Vibe-coded output is identifiable by its symptoms: large confident functions with little error handling, magic constants, and comments describing intent over behavior. The debugging day converts vibes into guarantees via three steps: (1) write tests capturing expected I/O, (2) add logging and metrics to see real data, (3) split monoliths into testable units. Key practice: treat AI output like a junior dev's draft PR, containerize for reproducibility, and pin the model plus temperature/seed alongside dependencies.
