When you describe your idea, octto opens an interactive UI:

Click options instead of typing
See all questions at once
Answer in any order
Watch follow-ups appear instantly
Review the final plan visually

10 minutes of terminal typing → 2 minutes of clicking.

Quick Start

Add to ~/.config/opencode/opencode.json:

{ "plugin": ["octto"] }

Select the octto agent:

I want to add a caching layer to the API

A browser window opens. Click your answers. Done.

Parallel Branches

Your request is split into 2-4 exploration branches. All initial questions appear at once:

         ┌─ Branch 1: [question card]
Request ─┼─ Branch 2: [question card]
         └─ Branch 3: [question card]
                ↓
        Answer any, in any order

Each branch goes as deep as needed. Some finish in 2 questions, others take 4.

How It Works Behind the Scenes

3 Agents

Agent	Job
bootstrapper	Splits your request into branches
probe	Decides if a branch needs more questions
octto	Orchestrates the session

The Flow

Bootstrapper creates 2-4 branches from your request
Each branch gets an initial question → all shown in browser
You answer (click, not type)
Probe agent evaluates: more questions or done?
Repeat until all branches complete
Final plan shown for approval
Design saved to docs/plans/
