Introducing dsh-env-inspector-plus: A DeepSeek Harness Plugin

`dsh-env-inspector-plus` is a DeepSeek Harness (DSH) plugin designed to inspect the host process environment intuitively and securely. It adds a read-only page to the web “Settings → Environment Health Check” section and injects the `env_inspect` tool into the model. Core features include displaying host process identity (PID, working directory, etc.) and grouped environment variable statistics, along with itemized lists. Its security design strictly prevents values of sensitive variables (such as credentials) from leaving the host, returning only boolean values and lengths. Installation is performed via the CLI and requires restarting the process; it supports both Chinese and English, making it suitable for developers to quickly troubleshoot environment configurations.
