Project 01 · Vibe Coding vs Harness Engineering

Objective

Build the same capability under controlled conditions and observe how harness design changes reliability.

Steps

  1. Define the task and acceptance criteria.
  2. Run the agent without a harness and record scope, tests, modified files and completion claims.
  3. Add AGENTS.md, feature_list.json and progress.md.
  4. Run the governed session with the same core prompt.
  5. Compare baseline vs harnessed execution.
