Show HN: LangAlpha – what if Claude Code was built for Wall Street?

LangAlpha is an open-source AI agent framework for financial analysis that applies Claude Code's persistent workspace architecture to investment research. It treats investing as an iterative Bayesian process where conviction is refined over weeks, using persistent agent workspaces to compound research. The framework includes Programmatic Tool Calling (agents execute Python locally rather than dumping raw data into LLM context), parallel subagents, and integrations with financial APIs.
