Phased Software Engineering Execution

Task

$ARGUMENTS

Reference

Subagent execution follows the Ralph pattern. Each phase workspace is a self-contained Ralph environment: CLAUDE.md (agent instructions), prd.json (story state machine), progress.txt (learning persistence). Subagents are autonomous — they read their workspace instructions and execute independently.

The Sugar library (src/lib/) is the source of truth for all execution logic. Skills delegate to sugar CLI commands for workspace management, story state, consensus, and pattern propagation.

Prompt reinforcement

Use prompt repetition at every decision boundary: state the task, provide context, give the instruction, restate context briefly, repeat the instruction. Apply at skill level (restate $ARGUMENTS before each phase), subagent level (each workspace CLAUDE.md repeats the task), and per-story (restate acceptance criteria before implementing).
