Project 01 · Vibe Coding vs Harness Engineering
Objective
Build the same capability under controlled conditions and observe how harness design changes reliability.
Steps
- Define the task and acceptance criteria.
- Run the agent without a harness and record scope, tests, modified files and completion claims.
- Add AGENTS.md, feature_list.json and progress.md.
- Run the governed session with the same core prompt.
- Compare baseline vs harnessed execution.
Metrics
