Clear Thought Ultraplan

Clear Thought UltraPlan

UltraPlan's 6-phase planning pipeline + Clear Thought's 11 thinking frameworks.

From plain-English idea to AI-executable implementation plan, with structured thinking at every step.

What It Does

This Claude Code plugin transforms your idea into a complete, ready-to-build plan. It combines:

• UltraPlan: 6-phase planning pipeline (UNDERSTAND → RESEARCH → PLAN → REVIEW → VALIDATE → OUTPUT) with exhaustive discovery, parallel research, structured planning, self-review, and traceability validation
• Clear Thought: 11 structured thinking frameworks (mental models, design patterns, collaborative reasoning, etc.) applied at the right moment in each phase

The result: plans that are not just thorough, but well-reasoned.

How Thinking Frameworks Enhance Each Phase

Phase	Thinking Frameworks Used	What They Add
1. UNDERSTAND	Mental Models + Metacognitive Monitoring	First Principles decomposition of the idea before questions. Knowledge gap assessment for better questioning.
2. RESEARCH	Scientific Method + Decision Framework	Form testable hypotheses about tech choices. Weighted criteria evaluation for competing options.
3. PLAN	Design Patterns + Programming Paradigms + Visual Reasoning + Structured Argumentation	Select architecture patterns. Choose paradigms per section. Create architecture diagrams. Justify decisions with structured arguments.
4. REVIEW	Collaborative Reasoning + Debugging Approaches + Metacognitive Monitoring	Multi-persona review (security expert, user advocate, devil's advocate). Pre-mortem failure analysis. Confidence calibration.
5. VALIDATE	Scientific Method + Sequential Thinking	Verify hypotheses against plan evidence. Systematic step-by-step requirement tracing.
6. OUTPUT	Visual Reasoning + Mental Models	Architecture summary diagrams. Pareto check on highest-value sections.

The 11 Thinking Frameworks

#	Framework	Origin	Purpose
1	Mental Models	Clear Thought	First Principles, Pareto, Occam's Razor, Rubber Duck Debugging
2	Design Patterns	Clear Thought	Modular architecture, API patterns, state management, security
3	Programming Paradigms	Clear Thought	OOP, functional, reactive, event-driven, concurrent
4	Debugging Approaches	Clear Thought	Binary search, cause elimination, divide & conquer
5	Sequential Thinking	Clear Thought	Step-by-step reasoning with revision and branching
6	Collaborative Reasoning	Clear Thought	Multi-persona debate, consensus building
7	Decision Framework	Clear Thought	Weighted criteria, decision trees, scenario analysis
8	Metacognitive Monitoring	Clear Thought	Confidence calibration, bias detection, uncertainty tracking
9	Scientific Method	Clear Thought	Hypothesis testing, variable identification, evidence evaluation
10	Structured Argumentation	Clear Thought	Thesis-antithesis-synthesis, premise evaluation
11	Visual Reasoning	Clear Thought	Architecture diagrams, data flow, bottleneck detection

Quick Start

/ultraplan-ct I want to build a recipe sharing app

What happens:

1. Pre-Discovery Analysis: First Principles decomposition + knowledge assessment
2. Discovery: 40-70 multiple-choice questions across 9 categories
3. Research: 3 parallel agents + hypothesis testing + weighted evaluation
4. Planning: PRD + technical plan with design patterns + architecture diagrams
5. Review: Multi-persona review + pre-mortem debugging + confidence rating
6. Validation: Sequential tracing + hypothesis verification
7. Output: Visual summaries + Pareto-prioritized execution guide
