deep-thinking

Applies the six-phase deep-thinking methodology to any coding or design task. Phase 0 (Clarify) is a mandatory human intake gate that must complete before any reading or planning begins. Combines the Planning pattern (goal decomposition into ordered atomic steps with preconditions and effects), the Reflection pattern (adversarial self-critique of assumptions and failure modes), the Goal Setting and Monitoring pattern (observable success criteria per phase), and the Human-in-the-Loop gate (plan approval before execution begins). Use when: a task requires careful reasoning before action, when asked to 'plan first', 'think before acting', 'reason through', 'deep think', 'beast mode', 'thorough analysis', or 'don't rush'. Triggers on: 'plan first', 'think through', 'reason deeply', 'deep think', 'beast mode', 'thorough plan', 'analyze before acting', 'planning pattern', 'reflect before'.
