Harness Engineering

Working with AI (Harness Engineering)

Designing environments where AI agents can only produce good results. A 36-step automated pipeline from ideation to validation, design, build, and launch.

01

Idea Phase

Ideation & Validation

1

AI Brainstorming & Trend Scoring

Diverge ideas with AI, discover topics based on trend data. Even vague requests get refined

2

CEO Direction → Market Research → CSO Validation

AI CEO sets direction, Researcher conducts market research, AI CSO validates risks, feasibility & target user personas. No-Go triggers re-direction

3

Business Model Design

Systematically design revenue model, pricing strategy, and unit economics

4

CEO Gate

PASS / Revise BM / Change direction. Proceeds to Design Phase on pass

02

Design Phase

Design & Architecture

1

Tech Stack & DB Schema Design

CTO decides tech stack, data-engineer designs DB, CTO reviews. FAIL triggers redesign

2

UX/UI Design & Debate

product-designer creates UX→UI sequentially, each verified by reviewers, then UX↔UI design debate. User flows become the basis for API design

3

API Design & DB-API Consistency Check

backend-dev designs API based on UX flows, CTO verifies DB-API consistency. Mismatch triggers DB redesign

4

Execution Plan & Plan Critic

Planner generates implementation plan, plan-critic scores on 6 criteria. Iterates until pass

5

CTO Gate

Integrated validation of design + plan. Proceeds to Build Phase on pass

03

Build Phase

Implementation & Review

1

Parallel Implementation

frontend / backend / mobile / ai-engineer agents develop simultaneously

2

Migration Review (DBA)

DBA verifies DB changes. Issues route back to implementation

3

Code Review + Security Review

code-reviewer checks quality, security-reviewer scans for vulnerabilities

4

QA Testing

qa-engineer runs Unit / Integration / E2E tests. FAIL routes back to implementation

5

Deployment Setup (DevOps)

devops configures CI/CD pipeline, Docker containers, and deployment environment. Prepares for functional verification in Verify Phase

04

Verify Phase

Verification & Launch

1

Functional Verification (Simulator)

Run actual app to verify functionality. FAIL routes back to Build Phase

2

UI Verification & Usability Test

Screenshot-based visual verification + user perspective usability test. Implementation bugs → Build Phase, design issues → Design Phase

3

Launch Debate

CEO ↔ CTO ↔ CSO three-way meeting. Code fix / Design change / PASS decision

4

Completion Report

Final report generated after launch approval
