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

When to Use

• You need to configure a Rails project so it runs correctly inside Conductor workspaces.
• The project should support parallel coding agents with isolated ports, Redis settings, and shared secrets.
• You want the standard conductor.json, bin/conductor-setup, and script/server scaffolding for a Rails repo.

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', ...)

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
