Siftos · felipcsousa bundle SiftOS — Product judgment for coding agents. Gives agents persistent product context (strategy, evidence, prior decisions, learnings) and uses it to prioritize work, critique ideas, catch contradictions and improve product decisions in the conversation. Use for "what should we build", "critique this spec/PRD/PR", "does this align with our strategy", "did it work", product-aware implementation preflight, and durable product memory. Product memory lives in .product/ (Markdown + Git). Human owns the decision; automation is always user-chosen.
