Introduction
Turn Prompts into Protocols
ReasonKit is a structured reasoning engine that forces AI to show its work. Every angle explored. Every assumption exposed. Every decision traceable.
The Problem
Most AI responses sound helpful but miss the hard questions.
You ask: “Should I take this job offer?”
AI says: “Consider salary, benefits, and culture fit.”
What’s missing: Manager quality, team turnover, company trajectory, your leverage, opportunity cost, where people go after 2-3 years…
The Cost of Wrong Decisions: Without structured reasoning, decisions lead to financial loss and missed opportunities. With structured protocols, errors are caught and costly mistakes are prevented before they compound.
The Research: Tree-of-Thoughts reasoning achieved 74% success rate vs 4% for Chain-of-Thought on complex reasoning benchmarks (Yao et al., NeurIPS 2023). This dramatic difference shows why structured, multi-path exploration beats linear step-by-step thinking.
ReasonKit solves this by making AI reasoning structured, auditable, and reliable.
The Solution: ThinkTools
ReasonKit provides five specialized ThinkTools, each designed to catch a specific type of oversight:
| Tool | Purpose | Catches |
|---|---|---|
| GigaThink | Explore all angles | Perspectives you forgot |
| LaserLogic | Check reasoning | Flawed logic hiding in cliches |
| BedRock | Find first principles | Simple answers under complexity |
| ProofGuard | Verify claims | “Facts” that aren’t true |
| BrutalHonesty | See blind spots | The gap between plan and reality |
The 5-Step Process
Every deep analysis follows this pattern:
1. DIVERGE (GigaThink) → Explore all angles
2. CONVERGE (LaserLogic) → Check logic, find flaws
3. GROUND (BedRock) → First principles, simplify
4. VERIFY (ProofGuard) → Check facts, cite sources
5. CUT (BrutalHonesty) → Be honest about weaknesses
Quick Example
# Install
cargo install reasonkit-core
# Ask a question with structured reasoning
rk think "Should I ask for a raise or look for a new job?" --profile balanced
