This repo is a structured AI-assisted long-form article writing system, primarily delivered as a Claude Code plugin and a Tauri desktop app. It orchestrates a 14+ stage workflow (topic clarification, research, drafting, humanization, fact-checking, export) using specialized subagents and a central workflow contract (`collab_v2.json`). The system is model-agnostic, supporting Anthropic-compatible APIs including Chinese providers. It includes extensive tooling for evidence management, style modeling, blind evaluation, and publication metrics. While the core functionality is robust and well-tested, the codebase suffers from triple directory mirroring (`.claude/`, `claude-runtime/`, `plugins/writing-agent/`) requiring manual sync, hardcoded Windows paths in the desktop app, and a partially unverified style library. The architecture cleanly separates agent prompts (Markdown), runtime scripts (Python/Node), and a Tauri frontend, making the workflow itself reusable as a pattern for multi-stage AI agent orchestration.
