How Ralph Uses It

Section titled “How Ralph Uses It”

Ralph spawns Cursor with:

Terminal window
cursor -p "<boot prompt>" --output-format stream-json
  • -p — print mode (non-interactive, single prompt)
  • --output-format stream-json — structured JSONL output
  • No --max-turns support — ralph uses its timeout mechanism

Agent Instructions

Section titled “Agent Instructions”

Ralph’s loop prompt is self-contained — it does not generate or manage .cursor/rules/ or any other agent-specific instructions file. All methodology content, roles, and behavioral rules are injected directly into the agent session.
