Automatically generate and verify loop invariants for algorithm correctness proofs

General

What this skill does


# Loop Invariant Generator

## Purpose

Provides expert guidance on generating and verifying loop invariants for algorithm correctness proofs using formal methods.

## Capabilities

- Infer candidate loop invariants from code structure
- Verify initialization, maintenance, and termination conditions
- Generate formal proof templates
- Handle nested loops and complex data structures
- Export to theorem provers (Dafny, Why3)
- Suggest invariant strengthening

## Usage Guidelines

1. **Code Analysis**: Analyze loop structure and identify key properties
2. **Candidate Generation**: Generate candidate invariants from code patterns
3. **Verification**: Check initialization, maintenance, termination
4. **Strengthening**: Refine invariants to prove desired properties
5. **Export**: Generate proof obligations for theorem provers

## Tools/Libraries

- Dafny
- Why3
- SMT solvers (Z3, CVC5)
- Static analysis frameworks

let-fate-decide

Included

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
