Viber

You Imagine It. Tasks Build It.

A Viber is your machine running the OpenViber runtime. It is the engine that executes AI Tasks.

How It Works

graph TB subgraph daemon["Viber Daemon (your machine)"] subgraph openviber["OpenViber runtime"] t1["dev-task"] t2["researcher-task"] t3["pm-task"] end end

Your machine becomes a Viber — a runtime that executes one or more Tasks. Each task has a distinct role. You talk to them naturally:

You:   "Build a landing page for our new product, dark theme"
Task:  I'll create a landing page. Here's my plan:
       1. Scaffold Next.js project
       2. Design hero + feature sections
       3. Deploy to Vercel
       Should I proceed?
You:   "Go ahead"
Task:  On it. You can watch in the terminal panel...

The Viber Runtime

A Viber is a single machine running the OpenViber runtime. It provides:

  • Scheduler — Runs tasks on cron schedules (daily research, weekly reports)
  • Credentials — Shared account access for all tasks on the Viber
  • Config — Identity and settings at ~/.openviber/ (lightweight, portable)
  • Spaces — Working data at ~/openviber_spaces/ (repos, research, outputs)

Connecting a Viber

From the OpenViber Board, click Add Viber to generate a start command:

npx openviber start --token eyJub2RlIjoiYTFiMmMz...

This bootstraps the Viber, creates ~/.openviber/, and connects to the Board — no inbound ports needed.

Multiple tasks coordinate through external systems (GitHub issues, email) rather than talking to each other directly. This keeps everything simple and stateless.

Tasks

A Task is a specialized AI worker with a defined role. One Viber can run multiple tasks.

Tasks share the Viber’s workspace and memory — they belong to the same user and workflow.

See: Tasks for complete task documentation.

Intent-Driven Creation (Viber Board)

In the web UI, the New Task flow is intent-first and environment-aware:

  1. Pick an intent template (for example: Build a Feature, Code Review, Railway Deploy Failures)
  2. OpenViber pre-fills the task goal from the template
  3. OpenViber infers required skills from the intent
  4. OpenViber compares required skills against the selected Viber’s currently available skills
  5. If a required skill is missing, the UI opens a guided prerequisite flow before launch
  6. Once required skills are ready, the task auto-launches with the selected intent body

How Required Skills Are Inferred

OpenViber merges skill requirements from three sources (highest confidence first):

  1. intent.skills (explicit per-template list)
  2. A skills: section declared inside the intent body
  3. Keyword detection in the intent text (for skill-specific terms)

This gives good defaults for built-in templates while still letting you create precise custom templates.

Guided Setup Before Launch

When a selected Viber is active but a required skill is not ready, OpenViber starts a proactive setup flow:

  • checks Viber availability
  • runs skill provisioning for supported skills
  • handles auth guidance when the skill needs external login
  • retries launch automatically when prerequisites become available

If the Viber is offline, OpenViber asks you to bring it online before launching the task.

Where to Manage Intents

You can manage built-in and custom intent templates in Settings → Intents:

  • create and edit custom templates
  • replicate built-in templates into editable user templates
  • keep intent instructions aligned with your team workflows

Working Modes

ModeWhen to Use
Always AskBuilding trust — task asks before each action
Viber DecidesDaily work — task acts within policy, escalates risky actions
Always ExecuteOvernight runs — maximum autonomy, intervene by exception

Start with “Always Ask” and graduate to “Task Decides” as you build confidence.

You Stay in Control

Your Viber works autonomously but you always have oversight:

  • Observe — Watch terminal output in real time via tmux streaming
  • Intervene — Pause, redirect, or stop at any point through chat
  • Approve — Sensitive actions require explicit permission
  • Audit — Every action is logged; budget limits prevent runaway costs
