bereniketech/conductor-setup

Set up this Rails project for Conductor, the Mac app for parallel coding agents.

What to Create

1. conductor.json (project root)

Create conductor.json in the project root if it doesn't already exist:

{
  "scripts": {
    "setup": "bin/conductor-setup",
    "run": "script/server"
  }
}

2. bin/conductor-setup (executable)

Create bin/conductor-setup if it doesn't already exist:

#!/bin/bash
set -e

# Symlink .env from repo root (where secrets live, outside worktrees)
[ -f "$CONDUCTOR_ROOT_PATH/.env" ] && ln -sf "$CONDUCTOR_ROOT_PATH/.env" .env

# Symlink Rails master key
[ -f "$CONDUCTOR_ROOT_PATH/config/master.key" ] && ln -sf "$CONDUCTOR_ROOT_PATH/config/master.key" config/master.key

# Install dependencies
bundle install
npm install

Make it executable with chmod +x bin/conductor-setup.

3. script/server (executable)

Create the script directory if needed, then create script/server if it doesn't already exist:

#!/bin/bash

# === Port Configuration ===
export PORT=${CONDUCTOR_PORT:-3000}
export VITE_RUBY_PORT=$((PORT + 1000))

# === Redis Isolation ===
if [ -n "$CONDUCTOR_WORKSPACE_NAME" ]; then
  HASH=$(printf '%s' "$CONDUCTOR_WORKSPACE_NAME" | cksum | cut -d' ' -f1)
  REDIS_DB=$((HASH % 16))
  export REDIS_URL="redis://localhost:6379/${REDIS_DB}"
fi

exec bin/dev

Make it executable with chmod +x script/server.

4. Update Rails Config Files

For each of the following files, if they exist and contain Redis configuration, update them to use ENV.fetch('REDIS_URL', ...) or ENV['REDIS_URL'] with a fallback:

config/initializers/sidekiq.rb

If this file exists and configures Redis, update it to use:

redis_url = ENV.fetch('REDIS_URL', 'redis://localhost:6379/0')

config/cable.yml

If this file exists, update the development adapter to use:

development:
  adapter: redis
  url: <%= ENV.fetch('REDIS_URL', 'redis://localhost:6379/1') %>

config/environments/development.rb

If this file configures Redis for caching, update to use:

config.cache_store = :redis_cache_store, { url: ENV.fetch('REDIS_URL', 'redis://localhost:6379/0') }

config/initializers/rack_attack.rb

If this file exists and configures a Redis cache store, update to use:

Rack::Attack.cache.store = ActiveSupport::Cache::RedisCacheStore.new(url: ENV.fetch('REDIS_URL', 'redis://localhost:6379/0'))

Implementation Notes

• Don't overwrite existing files: Check if conductor.json, bin/conductor-setup, and script/server exist before creating them. If they exist, skip creation and inform the user.
• Rails config updates: Only modify Redis-related configuration. If a file doesn't exist or doesn't use Redis, skip it gracefully.
• Create directories as needed: Create script/ directory if it doesn't exist.

Verification

After creating the files:

1. Confirm all Conductor files exist and scripts are executable
2. Run script/server to verify it starts without errors
3. Check that Rails configs properly reference ENV['REDIS_URL'] or ENV.fetch('REDIS_URL', ...)
