description	Set up autonomous Claude Code loops (Ralph Wiggum pattern). Use when the user wants to run Claude continuously on a task until complete. Triggered by phrases like: run in a loop, autonomous agent, AFK coding, keep going until done, Ralph Wiggum loop, Claudius loop. Use when this capability is needed.

Claudius Maximus

Set up autonomous Claude Code loops based on the Ralph Wiggum pattern - running Claude repeatedly with no memory between sessions until all tasks are complete.

Key insight: Each iteration runs in a fresh Claude session. Progress is tracked externally in files. This eliminates context rot - Claude operates at peak intelligence every time.

When Invoked: Full Automation Workflow

When this skill is invoked, your goal is to fully automate setting up a Claudius loop in the user's project. This involves:

1. Proactive Scanning - Find relevant context before asking questions
2. Extensive Interview - Ask MANY questions via AskUserQuestion tool
3. Generate Artifacts - Create PRD.md, progress.txt, and customized runner

CRITICAL: Never be conservative with questions. Missing details leads to bad PRDs.

---

Phase 1: Proactive Scanning

Before interviewing the user, scan the project to understand context:

Agent Documentation

Look for existing agent guidance:

CLAUDE.md, GEMINI.md, AGENTS.md, AGENT.md, README.md
.claude/settings.json
docs/*.md, .docs/*.md

Extract: code standards, testing requirements, commit conventions, tech stack.

Existing Sub-Agents

Scan for existing sub-agents (these work in CLI via --agents flag):

.claude/agents/*.md
~/.claude/agents/*.md

For each agent found, extract from its YAML frontmatter:

• name - agent identifier
• description - what it does
• tools - allowed tools list
• model - which model to use
• The prompt (content after frontmatter)

Existing Skills

Scan for skills the agent could use:

.claude/skills/*/SKILL.md

NOTE: Skills may or may not be fully available in headless mode. As a backup, create a "skill shim" in the PRD that lists skills by name + path. Skills use progressive disclosure - don't bulk read, start with SKILL.md.

List each skill found with:

• Skill name
• Brief description (from SKILL.md frontmatter)
• Path to SKILL.md
• When it should be invoked

Build/Test Commands

Look for:

package.json (scripts section)
Makefile, Taskfile.yml
pyproject.toml, setup.py

Identify: test command, lint command, typecheck command, build command.

Existing PRD Files

Check if there's already a PRD:

PRD.md, prd.md, PLAN.md, TODO.md

---

Phase 2: Interview the User

ALWAYS use AskUserQuestion tool. Do NOT ask questions in plain text.

Ask questions in logical groups. Never skip a category.

Category 1: Project Context

• What is this project? (brief description)
• What tech stack is used?
• What are you trying to accomplish with this Claudius loop?
• Is this a new feature, refactor, test coverage, or something else?

Category 2: Task Breakdown

• What are the specific tasks that need to be done?
• Should I help break down a large task into smaller pieces?
• What order should tasks be completed in? (dependencies?)
• How would you describe "done" for each task?

Category 3: Constraints (Fail Conditions)

These are critical. Ask explicitly:

• What files/directories should the agent NOT modify?
• What actions are absolutely forbidden? Examples:
  • Don't deploy to production
  • Don't change database schema
  • Don't add new dependencies
  • Don't modify certain files
• Are there any external services the agent should NOT interact with?

Category 4: Pass Conditions

• What MUST be true for the entire workflow to be complete?
• What verification commands must pass? (tests, lint, typecheck)
• Is there a coverage threshold?
• Are there specific acceptance criteria?

Present discovered skills:

• "I found these skills: [list]. Which should be available to the loop agent?"
• "When should each skill be invoked?"

Category 6: Sub-Agents (if any found)

Sub-agents can be passed to Claude via the --agents CLI flag.

Present discovered agents:

• "I found these sub-agents: [list with descriptions]. Which should be included in the loop?"
• "For each selected agent, when should the loop agent invoke it?"

Explain that selected agents will be converted to JSON and passed via --agents flag.

Category 7: Git Workflow

• Should I create a new branch for this work? (Recommended: yes)
• What should the branch be named?
• Should commits be pushed after each task? (Recommended: yes)

Category 8: Iteration Limits

• How many iterations maximum? Recommendations:
  • Small tasks: 5-10
  • Medium features: 20-30
  • Large complex work: 50-100
• Do you want max-turns per iteration? (safety limit on agentic actions)

Category 9: Quality Bar

• Is this production code or prototype?
• What level of test coverage is expected?
• Should the agent write tests for new code?
• Any specific coding standards to follow?

---

Phase 3: Generate Artifacts

After gathering all information, generate these files in the project directory:

1. PRD.md

Use the template from templates/PRD_TEMPLATE.md. Include:

• Project context
• Task checklist (with [ ] checkboxes)
• Constraints (hard boundaries)
• Pass conditions
• Verification commands
• Skill shim (if skills discovered)
• Git workflow notes

2. progress.txt

Create an empty progress file:

# Progress Log

3. Agents JSON (if agents selected)

Convert selected sub-agents to JSON for the --agents CLI flag:

From agent .md file:

---
name: code-reviewer
description: Reviews code for quality
tools: Read, Glob, Grep
model: sonnet
---
You are a code reviewer. Analyze code and provide feedback.

To JSON:

{
  "code-reviewer": {
    "description": "Reviews code for quality",
    "prompt": "You are a code reviewer. Analyze code and provide feedback.",
    "tools": ["Read", "Glob", "Grep"],
    "model": "sonnet"
  }
}

4. claudius_runner.py (customized)

CRITICAL: Do NOT generate this file from scratch. Output capture and signal handling are complex and fragile on different OSs (especially Windows).

1. COPY the script from scripts/claudius_runner.py in this skill folder to the user's project root.
   • Use cp (Linux/Mac) or copy (Windows) or read_file + write_to_file.
2. MODIFY the SYSTEM_PROMPT constant in the copied file to include:

• Project-specific context
• Custom constraints
• Skill references

---

Phase 4: Confirm and Launch

Before the user runs the loop:

1. Confirm the PRD - Present a summary of what will be done

2. Verify git state - Is the repo clean? Is the branch created?

3. Explain the command:

   python claudius_runner.py <max_iterations>
   

4. Set expectations - Loops can take hours for complex work

---

Skill Shim Mechanism

Since user skills are NOT available in headless mode, include this in the PRD:

## Available Skills (Read When Needed)

> Skills use **progressive disclosure**. Don't bulk-read all files.
> Start with SKILL.md and branch out as needed.

| Skill Name | When to Use | Path |
|------------|-------------|------|
| my-skill | When doing X | `.claude/skills/my-skill/SKILL.md` |

The loop agent can then manually read skill files with the Read tool when relevant.

---

Signal Protocol

The runner script monitors Claude's output for these signals:

Signal	Meaning	Runner Action
<iteration_complete>	Single task done, more tasks remain	Kill process, start next iteration
<workflow_complete>	All tasks done, PRD complete	Kill process, exit loop successfully

The agent MUST output exactly one of these after each task.

---
