Claude Code TeammateTool - Source Code Analysis

This is not a proposal. This documents existing but hidden functionality found in Claude Code v2.1.19 binary, plus speculation on how it could be used.

Executive Summary

TeammateTool already exists in Claude Code. We extracted this from the compiled binary at ~/.local/share/claude/versions/2.1.19 using strings analysis. The feature is fully implemented but gated behind feature flags (I9() && qFB()).

Complete MySQL Export Guide - 100% Database Replication

Overview

This guide provides instructions for creating a complete 1:1 MySQL export that includes all databases, users with passwords, triggers, events, and procedures for testing environments.
