What does Logic Lens do differently from traditional linters?

Logic Lens performs deep, logic-driven code review using formal reasoning frameworks to catch logical errors, race conditions, security vulnerabilities, and algorithmic flaws that traditional linters miss. It analyzes actual code behavior rather than just syntax and style, checking across 9 risk categories including null handling, type safety, concurrency, resource management, security injection, boundary conditions, algorithm correctness, state management, and API contract violations.

What are the 9 risk categories Logic Lens checks?

The 9 categories are: Null/Undefined handling, Type Safety, Concurrency, Resource Management, Security Injection, Boundary Conditions, Algorithm Correctness, State Management, and API Contract violations. Each category targets a specific class of defect, from missing null checks to race conditions to SQL injection risks.

How do I use Logic Lens?

Install it via the Claude Code plugin marketplace or `npx antigravity-awesome-skills --claude`, then invoke it as `@logic-lens` followed by your review request (e.g., `@logic-lens review src/auth/login.ts for security issues`). You can review a single file, changed files in a branch, or an entire codebase.

What does Logic Lens output?

It outputs severity-ranked findings (CRITICAL/HIGH/MEDIUM/LOW) across the 9 risk categories, with each finding including an actionable fix suggestion to help you address the issue.

Should I use Logic Lens as a substitute for security audits or testing?

No—Logic Lens provides AI-powered analysis and should be combined with human review for production-critical decisions. It should not replace environment-specific testing or a full security audit.

Overview

Logic Lens

Logic Lens is a Claude Code skill that performs deep, logic-driven code review using formal reasoning frameworks. It analyzes code for race conditions, security vulnerabilities, type mismatches, and algorithmic flaws that only appear when reasoning through code behavior, going beyond what traditional syntax and style linters can detect. Use Logic Lens when you need to identify subtle errors in concurrent systems or complex algorithms where correctness depends on logical reasoning rather than syntactic validity.

What it does

Logic Lens performs deep, logic-driven code review for Claude Code using formal reasoning frameworks. Unlike traditional linters that check syntax and style, it analyzes code for race conditions, security vulnerabilities, type mismatches, and algorithmic flaws that only appear when you reason through the code's behavior.

When to use - and when NOT to

Use Logic Lens when you need to identify subtle errors that surface only during execution, such as race conditions in concurrent code, security vulnerabilities that emerge from logical flow, type mismatches that compilers miss, or algorithmic flaws in complex business logic. It is suitable for reviewing concurrent systems and algorithms where correctness depends on logical reasoning rather than syntactic validity.

Do not use Logic Lens when you only need syntax checking or code style enforcement - traditional linters handle those tasks more efficiently. It is also not the right tool when you need immediate, surface-level feedback during rapid prototyping where logical correctness is not yet the priority.

Inputs and outputs

You provide source code that requires logical analysis. Logic Lens receives your code and applies formal reasoning frameworks to trace execution paths, identify logical inconsistencies, and surface behavioral flaws. You receive a detailed analysis highlighting race conditions, security vulnerabilities, type mismatches, and algorithmic flaws discovered through reasoning about the code's behavior.

Who it's for

Logic Lens is built for developers working with Claude Code who need to go beyond surface-level code quality checks. It serves software engineers working with concurrent systems and developers responsible for ensuring logical correctness in complex algorithms. Unlike traditional linters that focus on syntax and style, Logic Lens addresses bugs that reveal themselves through reasoning about program behavior and execution flow.
