   we encountered that issue and fixed it + a separate sse event type to signal start/end of summarization for ui/ux. we also build a lot on top of it like more accurate token estimation, customized offloading mechanism etc.

   Thanks, very valid point. We are building towards a benchmark as well. hope we can share more quantitive metric soon.

   This is some quality critique i am expecting. We currently persist logs for every single line of code agent executed in the sandbox. We also have agent trajectory persisted with infra from langchain ecosystem. That said, i share the same be

   would it be more professional in your opinion if i am claiming i make $xxxxx via this tool? I thought i have clearly stated that cool visuals is for >demo purpose and to attract attention. I do not want to post any dramatic statement to

   there will always be people lose money regardless, that's part of stock market. i hope at least with tools like this, people can make investment decisions more systematically and with discipline by relying on research rather than impul

   we do have something similar to a personal or workspace level investment wiki on the roadmap. As for now, it would be more like how swe working on a codebase and build stuff incrementally by commits. We are taking a workspace centric approa

   Great advice! For demo purpose and to attract attention, i was primarily picking some cases with cool visuals (like the screenshot of the AI supply chain you mentioned). we have some internal eval and will try to add more cases in the publi

    Some technical context on what we ran into building this. MCP tools don't really work for financial data at scale. One tool call for five years of daily prices dumps tens of thousands of tokens into the context window. And data vendors

    Hi HN. We built LangAlpha because we wanted something like Claude Code but for investment research. It's a full stack open-source agent harness (Apache 2.0). Persistent sandboxed workspaces, code execution against financial data, and a
