DSH PackyCode API

DeepSeek Harness (DSH) has introduced the PackyCode API plugin, designed to simplify the model invocation workflow. The plugin provides core features such as built-in model routing, automatic multi-key rotation, key selection by group, real-time balance viewing, and local credential management. During installation, a version number must be specified (e.g., `dsh-packycode-api@1.2.9`). It supports adding API keys and selecting models through settings. The plugin is optimized for domestic network environments and integrates with Claude local CLI, image generation, and web search. Keys are stored only in the local credential file to ensure security. It is suitable for developers who need to manage multiple models and API keys.
