DeepSeek Harness Plugin: human-writing-skills

The DeepSeek Harness (DSH) plugin `human-writing-skills` is an open-source human-in-the-loop AI toolkit designed to address style drift, character consistency, and factual errors in long-form writing. By combining Python tools with Markdown instructions, it provides writing editing, style auditing, continuity ledger extraction, and quality control. It supports command-line or MCP-service workflows and requires Python 3.9+ and Node.js ^22.19.0. Users can customize styles and whitelists through configuration files for text optimization in areas such as self-media and novel writing, though final output still requires human review.
