dsh-evolution-lab: Self-Evolution of Proof-Carrying Skills in DeepSeek Harness

The Evolution Lab plugin for DeepSeek Harness (DSH) is designed to address security and consistency challenges in maintaining SKILL.md. The tool uses an isolated evaluation process: by comparing a baseline skill against a candidate skill in a separate process and running reserved test cases, it enables atomic skill upgrades or rollbacks without manual intervention. The plugin supports the evolution of a single Markdown skill, with canary testing, privacy protection (HMAC-based de-identification), and strict safety boundaries. Through the `/evolution` command set, users can manage configurations, run evaluations, view history, and handle rollbacks. Installation requires specifying the version, and the automatic evolution feature must be enabled in the conversation header.
