DeepSeek Harness Skill Invocation Audit and Built-in Manager: dsh-echocat-skill-panel

`dsh-echocat-skill-panel` is an agent development plugin designed specifically for DSH to address the challenge of auditing skill invocations. It generates visual audit reports without relying on the model’s self-reporting, inferring invocation details from event streams. It also includes a built-in skill manager that supports installing, removing, updating, and referencing skills directly within the app. The plugin offers one-click installation (with multiple sources supported), background customization, and local image processing. After installation, restart DSH Desktop Beta for changes to take effect.
