Logic Lens

Overview

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

Powered by structured AI analysis, Logic Lens applies systematic logical inspection across 9 risk categories: null/undefined handling, type safety, concurrency, resource management, security injection, boundary conditions, algorithm correctness, state management, and API contract violations.

When to Use This Skill

• Use when you want a thorough logic review before merging a PR
• Use when a bug seems hard to find and standard linters aren't helping
• Use when reviewing security-sensitive code paths (auth, payments, file access)
• Use when refactoring complex business logic
• Use when onboarding to a new codebase and need to understand risk areas

How It Works

Logic Lens uses Claude Code's reasoning capabilities to:

1. Parse code structure and build a mental model of data flow
2. Apply formal logic checks across 9 risk categories
3. Trace execution paths for edge cases and boundary conditions
4. Identify security anti-patterns (injection, privilege escalation, data leakage)
5. Report findings with severity levels and actionable fix suggestions

Installation

# Install via Claude Code plugin marketplace
# Search: "logic-lens" in Claude Code > Extensions

# Or install via NPX (Antigravity)
npx antigravity-awesome-skills --claude
# Then invoke: @logic-lens

Examples

Example 1: Review a Single File

@logic-lens review src/auth/login.ts for security issues

Logic Lens output:

[CRITICAL] SQL Injection risk at line 42: user input concatenated into query string
[HIGH] Missing rate limiting on login attempts
[MEDIUM] Password comparison uses == instead of timing-safe comparison
[LOW] Error messages may leak valid usernames (user enumeration)

Example 2: Full Repository Scan

@logic-lens scan the entire codebase and prioritize by severity

Example 3: Pre-PR Review

@logic-lens review all files changed in this branch before I open a PR
