dsh-session-recall

`dsh-session-recall` is a Memory-category plugin in the DeepSeek Harness (DSH) ecosystem, designed to address the lack of native historical recall tools in models. Through the `ctx.sessionQuery` interface, it provides agents with deterministic cross-session full-text search capabilities. The plugin’s core features include support for locally persisted FTS5 indexes, optimized zero-hit substring fallback for Chinese tokenization, scope control based on the current working directory by default, and typed results containing fields such as session ID and title. After installation, agents can trigger search via natural language or code, making it suitable for scenarios requiring audit traceability and retrieval of raw logs.
