Ralph Engine

Automated feedback loop system integrating LSP diagnostics, AST-grep security scanning, and test validation for continuous code quality improvement.

Preset Architecture — the Ralph Engine as a goal preset

The /moai loop skill (.claude/skills/moai/workflows/loop.md) re-expresses this Ralph engine as a goal preset built ON the goal engine: a scan stage builds a finite issue queue, and the iterate-until-done decision is delegated to the goal engine (stop-goal) with the pre-filled condition "queue drained + diagnostics clean". In this preset architecture, this SKILL.md documents the underlying LSP / AST-grep / test / coverage diagnostic machinery that the goal-preset sweep drives; the preset layers the goal-engine composition on top of that machinery WITHOUT changing it. The four loop quadrants (goal-based sweep, turn-based /moai fix, time-based cadence, proactive CI-watch) are presets on the one goal engine, not independent engines.
