dsh-skill-curator: DeepSeek Harness Automatic Skill Curation Plugin

The dsh-skill-curator plugin for DeepSeek Harness is intended to address the issue of agents falling behind in maintaining SKILL.md files. It leverages background subagents to automatically review conversations and update the skill library, with support for manually triggered reviews. The plugin features safe writing, Git version rollback, and tool whitelisting mechanisms to ensure operations remain controlled. It depends on Node.js and is suitable for long-running agents that require continuous skill-library optimization and reduced manual intervention.
