RaV Town — Read-and-Vibe Town

A Claude Code plugin marketplace for multi-agent orchestration — autonomously implement features from Product Requirements Documents (PRDs). Coordinates parallel AI agents, each working in isolated git worktrees, to go from specification to merged pull request.

Installation

Add the marketplace and install the plugins you want:

/plugin marketplace add patelr3/agents
/plugin install rav-town@rav-town-marketplace
/plugin install worktree-devcontainer@rav-town-marketplace
/plugin install dev-browser@rav-town-marketplace

Plugins

rav-town

The core orchestration system. Includes:

Component	Type	Description
prd	skill	Generate structured PRDs from feature descriptions
ralph-prd	skill	Convert markdown PRDs to Ralph's JSON execution format
ralph-loop	skill	Iterative execution loop — one story per AI session
ravtown-mayor	agent	Fleet manager — coordinates parallel PRD implementations
ralph-agent	agent	Autonomous PRD processor — reads, converts, implements

Requires: worktree-devcontainer plugin for the /worktree skill used by the mayor and ralph agents.

→ Full documentation

worktree-devcontainer

Isolated development environments for AI sub-agents. Two composable skills:

Component	Type	Description
worktree	skill	Git worktree lifecycle — branch creation, worktree setup, sub-agent execution, PR creation, cleanup
dev-container	skill	Dev container lifecycle — build container from workspace, run AI tool inside, cleanup

Use worktree for branch isolation, dev-container for environment isolation, or both together for full isolation.

The dev container is pre-configured with Copilot CLI, Claude Code, and GitHub CLI. Credentials are forwarded from the host via ~/.git-credentials mount. See the tested workflow for an end-to-end validation.

dev-browser

Standalone browser automation via Playwright. Navigate websites, fill forms, take screenshots, extract data, test web apps. Used by rav-town agents to visually verify UI changes, but works independently too.

Quick Start

1. Create a PRD

/prd Add a task priority system with high/medium/low levels

Creates docs/prds/prd-<date>-<feature>.md with status: todo.

2. Launch the Orchestrator

Start the ravtown-mayor agent, then submit PRDs:

Complete docs/prds/prd-2026-03-15-task-priority.md

Or submit everything:

Complete all todo PRDs

3. Watch It Work

The mayor delegates to ralph-agent subagents running in isolated worktrees. Each agent:

1. Converts the PRD to structured JSON
2. Implements stories one at a time (fresh AI session per story)
3. Runs quality checks, commits, logs progress
4. Creates and auto-merges a PR when done

How It Works

┌──────────────────────────────────────────────────────────────┐
│                      Ravtown Mayor                            │
│  Accepts PRDs → tracks state → invokes /worktree per PRD      │
└────────┬─────────────────────────────────────────────────────┘
         │
         ├─ /worktree #1 (port offset 10)
         │  ├─ creates branch ralph/<feature>
         │  ├─ spawns ralph-agent
         │  │   ├─ /ralph-prd → converts PRD to JSON
         │  │   └─ /ralph-loop → implements stories iteratively
         │  └─ creates PR → merges → cleans up
         │
         ├─ /worktree #2 (port offset 20)
         │  └─ parallel independent feature
         │
         └─ /worktree #3 (port offset 30)  [blocked]
            └─ waits for dependency to complete

PRD Format

PRDs flow through stages tracked by YAML frontmatter: todo → inprogress → complete.

Ralph JSON format:

{
  "project": "MyProject",
  "branchName": "ralph/feature-name",
  "description": "Feature description",
  "dependsOn": [],
  "userStories": [
    {
      "id": "US-001",
      "title": "Story title",
      "description": "As a user, I want X so that Y",
      "acceptanceCriteria": ["Criterion 1", "Typecheck passes"],
      "priority": 1,
      "passes": false,
      "notes": ""
    }
  ]
}

Key rules:

• Each story must be completable in one iteration (one AI context window)
• Stories ordered by dependency (schema → backend → UI)
• Every story needs "Typecheck passes" as a criterion
• UI stories need "Verify in browser using dev-browser skill"

Supported AI Backends

The ralph-loop supports three backends via --tool:

Tool	Command	Flag
GitHub Copilot CLI	copilot	--tool copilot (default)
Claude Code	claude	--tool claude
AMP	amp	--tool amp
