This repository implements a meta-skill (ex-skill) that generates digital personas of former romantic partners by analyzing chat histories from WeChat and iMessage. It is designed to be consumed by AI agent runtimes like OpenClaw, Claude Code, or DeepSeek Harness via the AgentSkills standard. The system guides users through conversational intake of relationship details (astrology, MBTI, attachment style), automatically decrypts and extracts WeChat/iMessage chat databases, analyzes communication patterns using LLM prompt templates, and writes a structured persona skill that can be interactively chatted with. The codebase consists of a SKILL.md orchestrator, six detailed LLM prompts (intake, analysis, persona builder, merger, correction handler), four Python tools (database decryption, message parsing, skill file management, version management), and an example persona. It is a specialized tool for cyber-immortality and digital persona creation, blending reverse engineering with psychological profiling.
