How to Dev

The exact workshop flow for picking an idea, scoping fast, and shipping a strong AI prototype in hackathon time.

1) Picking an idea

Look for a real problem with a connection to your life.

Validate quickly: where are people talking about it, and what are they saying?

Check if a solution already exists, then iterate instead of remaking the same thing.

Decide a scope that is demoable in the next 2 days.

Choose a challenge bigger than 30 minutes, but not "solving cancer."

Pick 1-3 wow features and spend your energy there.

Define done as a mini PRD: inputs, process, outputs.

Scope check

  • Demo in 2 days: yes or no?
  • 1-3 wow features: clear?
  • Rubric aligned: yes or no?
  • Done defined: inputs, process, outputs?

2) Build based on the rubric

Your project can be great, but if it does not meet judging criteria, it will not score well.

PRIORITY 01

Rubric first

Map each feature to a judging criterion before building.

PRIORITY 02

Core flow

Make one full user flow stable before adding extras.

PRIORITY 03

Demo reliability

Optimize for what you can show clearly under time pressure.

3) Coding workflow

Get the free trial and set up your project workspace.

Start with a README.md: stack, requirements, and features.

Context matters: clear prompting is a real life skill and directly improves code quality.

Workshop exercise: build a simple AI chatbot.

Choose models intentionally: each model has strengths, costs, and speed tradeoffs.

# define project
README.md # stack + requirements + features
npm install
npm run dev

Common tools

  • Backend: Supabase
  • Runtime: npm + localhost
  • AI tools: Claude, Antigravity, Codex, Lovable
  • Other editors: use what your team ships fastest with

4) GitHub setup

Get ready

Install GitHub app, create account, create the hackathon repo.

Work as a team

Add collaborators and use a clean git workflow for shared progress.

APIs (optional)

  • Auth + database: decide early
  • Local DB: keep files on your computer
  • Deployment: optional for MVP
  • Agents / n8n: optional automation layer
  • Endpoints: create and test visually

5) Resources

Use the resources in the Hackathon website during build day for links, docs, and team support.
