Warp Rails Bootstrap

Configure Warp terminal for optimal Rails development with colored tabs.

Critical Rules

READ THESE FIRST. VIOLATIONS WILL BREAK THE CONFIG.

1. MUST use AskUserQuestion - Do NOT generate the config until user selects their tabs
2. MUST use bin/dev - If bin/dev exists, use it. Do NOT parse Procfile.dev for individual commands
3. MUST use lowercase color names - Only valid: red, green, yellow, blue, magenta, cyan
4. MUST use exec: for commands - Format: - exec: bin/dev NOT - "bin/dev"
5. MUST use absolute paths - Never use ~ or relative paths in cwd field
6. MUST start YAML with --- - The document separator is required
7. MUST read reference docs - Before generating YAML, read @./references/launch-config-schema.md

Workflow

Execute these steps IN ORDER. Do not skip steps.

Step 1: Verify Rails Project

Run this command:

test -f config/application.rb && echo "RAILS PROJECT" || echo "NOT RAILS"

If NOT RAILS, stop and tell user to run from a Rails directory.

Step 2: Gather Project Context

Run these commands and store the results:

# Get absolute path (REQUIRED for cwd)
pwd

# Get project name from directory
basename "$(pwd)"

# Check for bin/dev
test -f bin/dev && echo "HAS_BIN_DEV=true" || echo "HAS_BIN_DEV=false"

# Check for background job processor
grep -l "sidekiq\|good_job\|solid_queue" Gemfile 2>/dev/null && echo "HAS_JOBS=true" || echo "HAS_JOBS=false"

IMPORTANT:

• If HAS_BIN_DEV=true, the dev command is bin/dev. Period. Do NOT look inside Procfile.dev.
• If HAS_BIN_DEV=false, the dev command is bin/rails server.

Step 3: STOP - Ask Tab Configuration

You MUST use AskUserQuestion here. Do NOT proceed until user responds.

Ask: "Which tabs do you want in your Warp launch configuration?"

Use multi-select with these options:

Label	Description
Server (green)	Run dev server (bin/dev or rails server)
Claude (blue)	Start Claude Code session
Shell (yellow)	Empty terminal for commands
Console (magenta)	Rails console
Logs (cyan)	Tail log/development.log

If HAS_JOBS=true, also include: | Jobs (red) | Background job processor |

WAIT FOR USER RESPONSE BEFORE CONTINUING.

Step 4: Read Reference Documentation

Before writing ANY YAML, read the schema reference:

Read @./references/launch-config-schema.md

This ensures you use the correct format.

Step 5: Generate Launch Configuration

Create the launch configuration file.

File location: ~/.warp/launch_configurations/{project-name}.yaml

EXACT FORMAT TO USE:

---
name: {project-name}
windows:
  - tabs:
      - title: Server
        color: green
        layout:
          cwd: {ABSOLUTE_PATH_FROM_PWD}
          commands:
            - exec: bin/dev
      - title: Claude
        color: blue
        layout:
          cwd: {ABSOLUTE_PATH_FROM_PWD}
          commands:
            - exec: claude
      - title: Shell
        color: yellow
        layout:
          cwd: {ABSOLUTE_PATH_FROM_PWD}

FORMAT RULES:

• File MUST start with --- (YAML document separator)
• color MUST be lowercase: green, blue, yellow, magenta, cyan, red
• color MUST NOT be capitalized or an object with r/g/b values
• commands MUST use exec: prefix: - exec: bin/dev
• commands MUST NOT be plain strings like - "bin/dev"
• cwd MUST be the absolute path from pwd command (no quotes needed)
• cwd MUST NOT use ~ or relative paths

Step 6: Display Summary

Show the user what was created:

Warp launch configuration created for {project-name}!

Location: ~/.warp/launch_configurations/{project-name}.yaml

How to use:
  Keyboard:     Ctrl-Cmd-L → select "{project-name}"
  Direct URL:   warp://launch/{project-name}.yaml

Tabs configured:
  {list each tab with color and command}

Common Mistakes to Avoid

Wrong	Right
color: Green	color: green
color: { r: 34, g: 197, b: 94 }	color: green
commands: ["bin/dev"]	commands: [- exec: bin/dev]
cwd: ~/project	cwd: /Users/avi/project
cwd: .	cwd: /Users/avi/project
Missing --- at start	Start file with ---
Parsing Procfile.dev for commands	Just use bin/dev
Skipping AskUserQuestion	MUST ask and wait for response
