🛠️ Core Tools

boolean_evaluate

Systematically evaluate boolean expressions with step-by-step verification

Input: "True and False or not True"
Output: Step-by-step boolean evaluation with operator precedence

date_calculate

Perform date arithmetic with computational verification

Input: base_date="2023-01-15", offset_days=7, format="MM/DD/YYYY"
Output: Verified date calculation with breakdown

object_count

Systematically count objects by category with verification

Input: items=["bear", "snake", "microwave", "cat"], target_category="animals"
Output: Categorized count with breakdown (3 animals)

state_track

Track object positions through a series of swaps/moves

Input: initial_state={"Alice": "red"}, operations=[{type: "swap", participants: ["Alice", "Bob"]}]
Output: Step-by-step state tracking

systematic_verify

Apply 6-step systematic reasoning protocol to any problem

Input: problem="Complex reasoning task", problem_type="boolean"

🎯 Usage Examples

Boolean Evaluation

// Instead of mental math: "True and False or not True"
// Use tool: boolean_evaluate({ expression: "True and False or not True" })
// Result: Systematic step-by-step evaluation with verification

Date Arithmetic

// Instead of guessing: "What's 7 days before March 31, 2023?"
// Use tool: date_calculate({ base_date: "2023-03-31", offset_days: -7 })
// Result: Verified calculation with breakdown

Systematic Reasoning

// For any complex problem:
// Use tool: systematic_verify({ problem: "Complex task", problem_type: "temporal" })
// Result: 6-step reasoning protocol applied

🧪 Testing

npm test          # Run test suite
npm run lint      # Check code quality
npm run dev       # Start development server
