Document Sync Skill for Claude Code

Overview

This skill provides comprehensive documentation synchronization by analyzing your actual codebase, tech stack, configuration, and architecture to ensure all documentation remains current and accurate. It operates on a "verify, never assume" principle, performing end-to-end comparisons against real code and dependencies to detect documentation drift automatically.

Core Principles

• Verify, Never Assume: Documentation is only updated after end-to-end comparison against real, current code and dependencies
• Deep System Introspection: Checks languages, frameworks, APIs, DBs, config, code patterns, and deployment targets
• Doc Trust Score: Every doc gets a trust rating based on evidence found in the codebase and config files

Quick Start

Natural Language Commands:

• "Run document sync analysis on my project"
• "Update docs so every API route matches the code"
• "Check if any doc mentions features no longer in the app"
• "List undocumented config variables"
