whale-persona: Persona Engine and Long-Term Memory Plugin

whale-persona is an open-source memory plugin for DeepSeek Harness, designed to address the issue of AI frequently forgetting personas and contracts. It is blank by default and supports managing self-identification, stance, image, tone, working agreements, and chain-of-thought language through configuration files. Its core mechanism is a mandatory human-confirmation mode, ensuring that long-term memory only takes effect after user approval. Installation requires Node.js 20 and DSH 0.1.6 or later, and it supports managing presets via command-line tools and previewing injected content. The plugin is built as a pure ESM module, is secure and controllable, and does not connect to the network.
