Claude Console

Pair with Claude Code in your Rails console. No quoting needed.

claude help me debug this user's deliverables
claude write a scope to find users with expired trials
claude why does User.find(42) have no campaigns

Claude runs Ruby code directly in your console session and sees the results — just like pair programming.

Add to your Gemfile:

gem "claude_console", group: :development

Requires Claude Code installed and authenticated on the machine.

Open rails console and type claude followed by your request:

irb(main):001> claude find the user with email "foo@bar.com" and show their campaigns
Asking Claude...

Here's what I found:

>> Running:
   user = User.find_by(email: "foo@bar.com")

=> #<User id: 42, email: "foo@bar.com">

>> Running:
   pp user.campaigns.select(:id, :name, :status)

[#<Campaign id: 1, name: "Summer 2026", status: "active">,
 #<Campaign id: 2, name: "Fall Launch", status: "draft">]

Claude sees your console history for context, runs code in your session, and can iterate on results.

# config/initializers/claude_console.rb

# Custom system prompt
ClaudeConsole.system_prompt = "You are a database expert..."

# Path to claude binary
ClaudeConsole.cli_path = "/usr/local/bin/claude"

# Additional env vars to clear (for auth isolation)
ClaudeConsole.clear_env_vars = ["MY_CUSTOM_API_KEY"]

Claude Console shells out to claude -p. It clears env vars like ANTHROPIC_API_KEY and CLAUDE_CONFIG_DIR from the subprocess so Claude Code uses its own stored credentials — not keys from your Rails environment.
