Jun 1, 2025June 2025 (bosun-ai/swiftide)—Delivered a set of high-impact features and reliability improvements that enhance performance, scalability, and observability, while laying groundwork for deeper backend pluggability and smarter search. Key outcomes include the introduction of a pluggable MessageHistory backend with Redis persistence and an AgentContext refactor to support multiple backends; enhancement of hybrid search across backends (DuckDB for BM25-based keyword search and cosine semantic search, with Qdrant filtering) for more relevant results; an OpenAI streaming delta mode to stream only new data instead of the full response to improve latency in streaming scenarios; streaming support for indexing files via ToolExecutor (stream_files) implemented in LocalExecutor; and the addition of ergonomic ToolError helpers to simplify error creation. Additional reliability improvements include a DuckDB creation duplicate safeguard with tests, token usage metrics across embeddings, prompts, and chat completions for better observability, and comprehensive dependency updates to latest versions for security and features.
