righting-software-system-design

Opt-in, collaborative system-design workflow based on Juval Löwy's iDesign methodology in *Righting Software*. Conducts a multi-phase interview (framing → use cases → volatility analysis → components → call-chain validation → report) that surfaces unknown-unknowns and produces a written recommendation at decompositions/{system-name}/report.md. **Run only when the user explicitly invites this workflow** — not for general architecture questions, lightweight design conversations, or quick "where should X live?" questions. Valid triggers: the user names the skill directly, references *Righting Software* / Juval Löwy / iDesign / "The Method" / volatility-based decomposition and asks to run a full session, asks for a "deep" or "structured" or "Löwy-style" system design session, or accepts a prior suggestion to run it. Wait for an explicit yes before entering Phase 0. The skill is interrogative — a back-and-forth interview that challenges each volatility candidate and proposes ones the user hasn't considered.
