Ralph Creator

Generate AFK loop scripts. Ralph runs claude -p --dangerously-skip-permissions in a loop — one task per iteration, progress tracked between iterations, stops when all tasks are done.

Workflow

Phase 1: Interrogate (grill-me)

Before generating anything, interrogate the user relentlessly about every aspect of the task. Do NOT accept vague answers.

Walk down each branch of the task tree, resolving dependencies between decisions one-by-one. Don't stop until every ambiguity is resolved.

Questions to resolve (skip if obvious from context):

1. What's the task? Concrete description of the end state.
2. What's the scope? How many subtasks? What's in, what's out?
3. What context does the agent need? Files, specs, docs, APIs.
4. What tools does the agent use? CLI commands, MCP tools, test runners.
5. What does "done" look like per task? Measurable acceptance criteria.
6. What must the agent NOT do? Constraints, off-limits areas, anti-patterns.
7. What order? Dependencies between tasks. What unblocks what?
8. What verification? How does the agent confirm each task is correct?

Keep pushing until you can write every backlog item with enough detail that a fresh Claude instance can execute it without asking questions. If the user says "just figure it out," push back: vague backlogs produce vague results.

Phase 2: Generate

Once requirements are nailed down, generate all artifacts:

1. Create .ralph/ directory

mkdir -p .ralph

Ensure .ralph/ is in .gitignore.

2. Write the backlog

Create .ralph/backlog.md. See references/backlog-format.md.

Rules:

• Each task: - [ ] checkbox, bolded title, clear description
• One task = one iteration = one context window
• Order by dependency, then priority
• Enough detail for a fresh Claude instance to execute without ambiguity

3. Generate the script

Create .ralph/ralph-<name>.sh from references/script-template.md.

Customize the placeholders:

• {{ADDITIONAL_CONTEXT_REFS}} — extra @path refs for skills, specs, style guides
• {{ONE_SENTENCE_DIRECTIVE}} — imperative statement: what each iteration produces
• {{EXECUTE_STEPS}} — numbered sub-steps for the domain-specific work
• {{VERIFY_INSTRUCTION}} — how to confirm the work is correct
• {{ADDITIONAL_RULES}} — domain-specific constraints

CRITICAL: The @ refs and prompt text MUST be in ONE quoted string passed to claude -p. The template handles this correctly — do not separate them.

If the task needs a style guide or reference material, put it in a SEPARATE file and add it to {{ADDITIONAL_CONTEXT_REFS}} as another @ reference. Do NOT inline it in the prompt.

4. Create tracking files

.ralph/progress.md:

# Progress
Working memory for ralph-<name>. Delete after run.
---

.ralph/lessons.md:

# Lessons
Patterns and mistakes. Review at start of each iteration.
---

See references/tracking-format.md for entry format.

5. Make executable and report

chmod +x .ralph/ralph-<name>.sh

Tell the user the run command:

env -u CLAUDECODE .ralph/ralph-<name>.sh <iterations>

Suggest iterations = task count + 2 (buffer for retries + final COMPLETE check).

Prompt Design Rules

1. Imperative first line — The prompt MUST open with YOUR JOB: <one sentence>. The model reads @ context files first (often 1000+ lines), so the prompt must snap it into execution mode, not summary mode.
2. Numbered steps, not section headers — Use STEPS: with numbered items, NOT markdown ## Section headers. Section headers read as documentation. Numbered steps read as commands.
3. Explicit "Do NOT" rules — End with a RULES: block including what the agent must NOT do. Without these, the model defaults to helpful-assistant mode.
4. Short and punchy — Under 30 lines. @ files provide context. The prompt is ONLY for instructions. Domain-specific guidance goes in separate @-referenced files.
5. @ context refs — Load docs upfront, don't waste tokens exploring.
6. Verification step — Agent confirms work before marking done.
7. Quality bar — Measurable "done" criteria, no ambiguity.
8. One task per iteration — Always include: ONLY work on ONE task. Do not continue to the next.
9. Completion sigil — Always: If all tasks are done, output <promise>COMPLETE</promise>.
10. Tool instructions — If using MCP tools, APIs, or CLIs, include explicit how-to in the execute steps.

Prompt Anti-Patterns

Gotchas

• env -u CLAUDECODE is required when launching from inside a Claude Code session, so sub-agents can spawn properly.
• Don't put domain guidance inline in the prompt. If you need style guides, conventions, or reference material, write them to a separate file and @-reference it.
• One task per iteration is non-negotiable. Multi-task iterations cause scope creep, partial completion, and context dilution.
• Delete progress.md between runs. It's working memory for a single run, not a permanent log.
• lessons.md persists. It accumulates across runs. Agents read it at the start of each iteration to avoid repeating mistakes.
