What Ralph does

Ralph runs a background evolve_step loop owned by the Ouroboros MCP tool, continuing until QA passes, convergence, a terminal evolution action, cancellation, or max_generations. Use it for tasks that must keep evolving until they work.

Ralph is cataloged under AI Engineering on DirSkills. Ralph comes from a repository tagged agent-os, agentic-ai, ai-agent, ai-coding-agent and claude-code.

Excerpt

/ouroboros:ralph

MCP-owned Ralph loop around background evolve_step jobs. "The boulder never stops."

Usage

ooo ralph --lineage-id <lineage_id>
/ouroboros:ralph --lineage-id <lineage_id>

# For a plain natural-language request, run `ooo interview` + `ooo seed` first,
# then call the MCP tool with a fresh lineage_id and the validated Seed YAML.

Trigger keywords: "ralph", "don't stop", "must complete", "until it works", "keep going"
