+983 stars this week to 2,478. Tree-of-thought with an architectural fix for premature convergence: a divergence phase spawns N isolated parallel agents under 15 distinct cognitive frames (economic-incentive, async-control-surface, gamification, redundancy-race) with zero shared context so branches can't anchor on each other, then a focus phase where a critic scores novelty, viability and fit, flags traps with reasons, clusters by pattern and deepens top-K survivors. Across six open-ended engineering problems: breadth 9.0 vs 4.83, novelty 7.83 vs 2.67, trap detection 9.50 vs 1.83, actionability 9.50 vs 6.50 against single-shot. And it publishes cost alongside: ~2.3× latency, ~1.9× tokens. Publishing the cost is the rare part. (GitHub)
