Ralph Command Generator

Generate optimized loop commands for automating Claude Code, Gemini CLI, or Grok CLI with PROMPT.md.

Step 1: Choose AI Tool

Use AskUserQuestion: - Question: "Which AI CLI tool do you want to use?" - Header: "AI Tool" - Options: 1. "Claude Code (Recommended)" - "Claude AI assistant CLI" 2. "Gemini CLI" - "Google Gemini AI assistant" 3. "Grok CLI" - "xAI Grok AI assistant with agentic coding"

Store the choice for later.

Step 2: Choose Model

Use AskUserQuestion based on AI tool choice:

If Claude Code selected: - Question: "Which Claude model do you want to use?" - Header: "Model" - Options: 1. "Default (Recommended)" - "Use default model (currently Sonnet 4.5)" 2. "Haiku" - "Fastest and most cost-effective" 3. "Sonnet" - "Balanced performance and cost" 4. "Opus" - "Most capable, higher cost"

If Gemini CLI selected: - Question: "Which Gemini model do you want to use?" - Header: "Model" - Options: 1. "Default (Recommended)" - "Use default model" 2. "gemini-3-flash" - "Latest Gemini 3, fastest and most cost-effective" 3. "gemini-3-pro" - "Latest Gemini 3, most capable for complex tasks" 4. "gemini-2.5-flash" - "Stable production model, fast" 5. "gemini-2.5-pro" - "Stable production model, more capable"

If Grok CLI selected: - Question: "Which Grok model do you want to use?" - Header: "Model" - Options: 1. "Default (Recommended)" - "Use grok-code-fast-1, optimized for fast code generation and agentic loops" 2. "grok-4-latest" - "Latest Grok 4, most capable for complex reasoning" 3. "grok-beta" - "Preview of upcoming features"

Store the choice for later.

Step 3: Choose Operating System

Store the choice for later.

Step 4: Choose Complexity Level

Use AskUserQuestion: - Question: "What level of control do you need?" - Header: "Complexity" - Options: 1. "Simple (Recommended)" - "Basic loop with minimal options" 2. "Intermediate" - "Combine 2 control mechanisms" 3. "Advanced" - "Full control with multiple safeguards"

Step 5: Choose Loop Type (Based on Complexity)

If Simple:

Use AskUserQuestion: - Question: "What type of loop?" - Header: "Loop Type" - Options: 1. "Fixed count (Recommended)" - "Run exactly N times" 2. "Infinite with delay" - "Run forever with pauses" 3. "Stop file trigger" - "Run until STOP.txt exists"

If Intermediate:

Use AskUserQuestion: - Question: "What combination do you need?" - Header: "Features" - multiSelect: true - Options: 1. "Fixed iterations" - "Run max N times" 2. "Time limit" - "Run for max X minutes" 3. "Stop file" - "Stop when STOP.txt appears" 4. "Delay between runs" - "Pause X seconds" 5. "Show counter" - "Display run number" 6. "File monitoring" - "Stop at file size/lines"

If Advanced:

Use AskUserQuestion: - Question: "What features do you want?" - Header: "Features" - multiSelect: true - Options: 1. "Max iterations (Recommended)" - "Limit runs" 2. "Time limit (Recommended)" - "Max duration" 3. "Stop file (Recommended)" - "Manual stop" 4. "Delay between runs" - "Pause X seconds" 5. "Timestamp logging" - "Show time of each run" 6. "Counter display" - "Show run number"

Step 6: Gather Parameters

Based on selected features, ask for values:

If fixed iterations selected: - Question: "How many iterations?" - Options: "5 (Recommended)", "10", "20", "50", "100", "Custom"

If time limit selected: - Question: "Maximum duration?" - Options: "10 minutes (Recommended)", "30 minutes", "1 hour", "Custom"

If delay selected: - Question: "Delay between runs?" - Options: "5 seconds (Recommended)", "10 seconds", "30 seconds", "Custom"

If file monitoring selected: - Question: "Monitor by?" - Options: "File size (e.g., 5KB)", "Line count (e.g., 50 lines)", "Content (e.g., 'THE END')"

Step 7: Generate Command

Build the appropriate command based on: 1. AI tool choice (Claude or Gemini) 2. Model choice 3. Shell choice (PowerShell, CMD, Bash) 4. Complexity level 5. Selected features 6. Parameter values

IMPORTANT - Command Syntax:

For Claude Code (PowerShell/Bash): Use claude-code (NOT claude -p) to accept piped input. The -p flag requires an argument, not pipe.

  • Default: Get-Content PROMPT.md -Raw | claude-code --dangerously-skip-permissions
  • Haiku: Get-Content PROMPT.md -Raw | claude-code --model haiku --dangerously-skip-permissions
  • Sonnet: Get-Content PROMPT.md -Raw | claude-code --model sonnet --dangerously-skip-permissions
  • Opus: Get-Content PROMPT.md -Raw | claude-code --model opus --dangerously-skip-permissions

For Claude Code (Bash): - Default: cat PROMPT.md | claude-code --dangerously-skip-permissions - With model: cat PROMPT.md | claude-code --model haiku --dangerously-skip-permissions

For Gemini CLI (PowerShell): Gemini CLI accepts stdin piping.

  • Default: Get-Content PROMPT.md -Raw | gemini --yolo
  • gemini-3-flash: Get-Content PROMPT.md -Raw | gemini --model gemini-3-flash --yolo
  • gemini-3-pro: Get-Content PROMPT.md -Raw | gemini --model gemini-3-pro --yolo
  • gemini-2.5-flash: Get-Content PROMPT.md -Raw | gemini --model gemini-2.5-flash --yolo
  • gemini-2.5-pro: Get-Content PROMPT.md -Raw | gemini --model gemini-2.5-pro --yolo

For Grok CLI (PowerShell): - Default: Get-Content PROMPT.md -Raw | grok-auto (uses default model from GROK_MODEL env var, auto-approves permissions) - grok-code-fast-1: Get-Content PROMPT.md -Raw | grok-auto -m grok-code-fast-1 - grok-4-latest: Get-Content PROMPT.md -Raw | grok-auto -m grok-4-latest - grok-beta: Get-Content PROMPT.md -Raw | grok-auto -m grok-beta

Command Templates

IMPORTANT - Placeholder Replacement:

For Claude Code: Replace [AI_COMMAND_WITH_PROMPT] with the FULL command including the prompt argument: - Default: claude -p (Get-Content PROMPT.md -Raw) --dangerously-skip-permissions - With model: claude -p (Get-Content PROMPT.md -Raw) --model haiku --dangerously-skip-permissions

For Gemini CLI: Replace [AI_COMMAND_WITH_PROMPT] with piped command: - Default: Get-Content PROMPT.md -Raw | gemini --yolo - With model: Get-Content PROMPT.md -Raw | gemini --model gemini-3-flash --yolo

For Grok CLI: Replace [AI_COMMAND_WITH_PROMPT] with piped command: - Default: Get-Content PROMPT.md -Raw | grok-auto - With model: Get-Content PROMPT.md -Raw | grok-auto -m grok-4-latest

CRITICAL: Claude Code requires the prompt as a command-line argument. Piping does NOT work with claude -p.

PowerShell - Simple Fixed:

for ($i=1; $i -le N; $i++) { $start = Get-Date; Write-Host "`n=== Run $i/N ===" -ForegroundColor Cyan; [AI_COMMAND_WITH_PROMPT]; $duration = ((Get-Date) - $start).TotalSeconds; Write-Host "⏱️  Time: $([math]::Round($duration, 2))s" -ForegroundColor Magenta }

PowerShell - Simple Fixed + Delay:

for ($i=1; $i -le N; $i++) { $start = Get-Date; Write-Host "`n=== Run $i/N ===" -ForegroundColor Cyan; [AI_COMMAND_WITH_PROMPT]; $duration = ((Get-Date) - $start).TotalSeconds; Write-Host "⏱️  Time: $([math]::Round($duration, 2))s" -ForegroundColor Magenta; if ($i -lt N) { Write-Host "⏸️  Waiting X seconds..." -ForegroundColor Yellow; Start-Sleep -Seconds X } }

PowerShell - Simple Infinite + Delay:

$i=1; while ($true) { $start = Get-Date; Write-Host "`n=== Run $i ===" -ForegroundColor Cyan; [AI_COMMAND_WITH_PROMPT]; $duration = ((Get-Date) - $start).TotalSeconds; Write-Host "⏱️  Time: $([math]::Round($duration, 2))s" -ForegroundColor Magenta; Write-Host "⏸️  Waiting X seconds..." -ForegroundColor Yellow; Start-Sleep -Seconds X; $i++ }

PowerShell - Advanced Full Control:

$end = (Get-Date).AddMinutes(M); for ($i=1; $i -le N -and (Get-Date) -lt $end -and -not (Test-Path STOP.txt); $i++) { $start = Get-Date; Write-Host "`n[$(Get-Date -Format 'HH:mm:ss')] Run $i" -ForegroundColor Cyan; [AI_COMMAND_WITH_PROMPT]; $duration = ((Get-Date) - $start).TotalSeconds; Write-Host "⏱️  Time: $([math]::Round($duration, 2))s" -ForegroundColor Magenta; if ($i -lt N) { Write-Host "⏸️  Waiting X seconds..." -ForegroundColor Yellow; Start-Sleep -Seconds X } }; Write-Host "`n✅ Complete!" -ForegroundColor Green

CMD - Simple Fixed:

for /L %i in (1,1,N) do @(echo. & echo === Run %i === & type PROMPT.md | [AI_COMMAND])

Note: CMD has limited capabilities. For time tracking, recommend PowerShell.

CMD - Simple Infinite + Delay:

for /L %i in (1,0,2) do @(echo. & echo === Run %i === & type PROMPT.md | [AI_COMMAND] & timeout /t X /nobreak > nul)

CMD - Advanced:

for /L %i in (1,1,N) do @(if exist STOP.txt exit & echo. & echo [%time%] Run %i & type PROMPT.md | [AI_COMMAND] & timeout /t X /nobreak > nul)

Note: For time tracking, use PowerShell (see RalphPowerShellComands.md).

Bash - Simple Fixed:

for i in {1..N}; do echo -e "n=== Run $i/N ==="; start=$(date +%s); cat PROMPT.md | [AI_COMMAND]; dur=$(($(date +%s) - start)); echo "⏱️  Time: ${dur}s"; done

Bash - Simple Fixed + Delay:

for i in {1..N}; do echo -e "n=== Run $i/N ==="; start=$(date +%s); cat PROMPT.md | [AI_COMMAND]; dur=$(($(date +%s) - start)); echo "⏱️  Time: ${dur}s"; [ $i -lt N ] && { echo "⏸️  Waiting X seconds..."; sleep X; }; done

Bash - Simple Infinite + Delay:

i=1; while :; do echo -e "n=== Run $i ==="; start=$(date +%s); cat PROMPT.md | [AI_COMMAND]; dur=$(($(date +%s) - start)); echo "⏱️  Time: ${dur}s"; echo "⏸️  Waiting X seconds..."; sleep X; ((i++)); done

Bash - Advanced:

end=$(($(date +%s) + M*60)); for i in {1..N}; do [ $(date +%s) -ge $end ] && break; [ -f STOP.txt ] && break; echo -e "n[$(date +%H:%M:%S)] Run $i"; start=$(date +%s); cat PROMPT.md | [AI_COMMAND]; dur=$(($(date +%s) - start)); echo "⏱️  Time: ${dur}s"; [ $i -lt N ] && { echo "⏸️  Waiting X seconds..."; sleep X; }; done; echo -e "n✅ Complete!"

Step 8: Create Command File

Create a timestamped filename in the format: ralphcommand-YYYY-MM-DD-HHMMSS.md

Example: ralphcommand-2026-01-14-233045.md

Use the Write tool to create this file in the current directory with:

File structure:

# Ralph Command

Generated: [timestamp]
Shell: [PowerShell/CMD/Bash]

## Command

```[shell-type]
[THE ACTUAL COMMAND]

How to run

  1. Make sure you have a PROMPT.md file in this directory
  2. Copy the command above
  3. Paste into your [PowerShell/CMD/Bash] terminal
  4. Press Enter

How to stop

  • Press Ctrl+C at any time [- OR create STOP.txt: echo $null > STOP.txt / touch STOP.txt] (if stop file enabled)

What it does

Runs [claude/gemini/grok] with PROMPT.md as input [N times / for M minutes / until stopped]. [Pauses X seconds between runs.] [Shows timestamp and run number.] [Displays execution time for each run.]

## Step 9: Notify User

After creating the file, tell the user the exact filename created:

✅ Created ralphcommand-YYYY-MM-DD-HHMMSS.md in your current directory!

The file contains your command ready to run. Just open it and copy the command.

Notes

  • CRITICAL FOR CLAUDE CODE: The prompt MUST be passed as a command-line argument, NOT via stdin pipe. Use claude -p (Get-Content PROMPT.md -Raw) --dangerously-skip-permissions. Piping does NOT work with claude -p.
  • For Gemini and Grok: Stdin piping works fine. Use Get-Content PROMPT.md -Raw | gemini --yolo or Get-Content PROMPT.md -Raw | grok-auto.
  • Model Selection is Optional: Always ask which model, but "Default" option omits the --model flag
  • For Claude Code (PowerShell):
  • Default format: claude -p (Get-Content PROMPT.md -Raw) --dangerously-skip-permissions
  • With model: claude -p (Get-Content PROMPT.md -Raw) --model <model> --dangerously-skip-permissions
  • Models: haiku, sonnet, opus
  • For Gemini CLI:
  • Default format: Get-Content PROMPT.md -Raw | gemini --yolo
  • With model: Get-Content PROMPT.md -Raw | gemini --model <model> --yolo
  • Models: gemini-3-flash, gemini-3-pro, gemini-2.5-flash, gemini-2.5-pro
  • Note: -p flag is deprecated in Gemini
  • For Grok CLI:
  • Use grok-auto PowerShell function which calls xAI API directly (perfect for automation)
  • Default format: Get-Content PROMPT.md -Raw | grok-auto (no -m flag, uses GROK_MODEL env var if set)
  • With model: Get-Content PROMPT.md -Raw | grok-auto -m <model>
  • Models: grok-code-fast-1, grok-4-latest, grok-beta, grok-4
  • Note: grok-auto is a PowerShell function that calls the xAI API directly (no CLI needed)
  • Default model (grok-code-fast-1 via GROK_MODEL env var) is recommended for automation loops (fastest responses)
  • Default to "Recommended" options when user is unsure
  • Keep commands on one line when possible for easy copy-paste
  • Always include time tracking - Show how long each run takes using Get-Date (PowerShell) or date +%s (Bash)
  • Always create timestamped file - Format: ralphcommand-YYYY-MM-DD-HHMMSS.md
  • DO NOT include cost tracking - No Get-LastCallCost function, no cost calculations, only time tracking
  • For cost tracking with Claude, tell users to check https://console.anthropic.com for actual API usage
  • When generating the final command for PowerShell:
  • For Claude: Replace [AI_COMMAND_WITH_PROMPT] with the full claude command including prompt argument
  • For Gemini/Grok: The piping is included in the template, just replace [AI_COMMAND] with the command after the pipe
