Included Skills1

heavy-thinkingskills/heavy-thinking/SKILL.md

Use when facing complex reasoning tasks — competition math (AIME, HMMT, Olympiad), STEM problems, GPQA-style hard science questions, intricate logical deduction, algorithmic / code-competition challenges, or any problem where a single chain-of-thought feels insufficient or where the initial approach is uncertain. Spawns K independent parallel reasoning agents and then performs critical sequential deliberation across their trajectories — explicitly NOT a majority vote. Do NOT activate for simple factual lookups, casual conversation, straightforward code edits with an obvious solution, or pure information-retrieval tasks.
