Summary

Every AI finance tool today treats investing as one-shot: ask a question, get an answer, move on. But real investing is Bayesian — you start with a thesis, new data arrives daily, and you update your conviction accordingly. It's an iterative process that unfolds over weeks and mo

33	## Why LangAlpha
34
35	Every AI finance tool today treats investing as one-shot: ask a question, get an answer, move on. But real investing is Bayesian — you start with a thesis, new data arrives daily, and you update your conviction accordingly. It's an iterative process that unfolds over weeks and months: refining theses, revisiting positions, layering new analysis on top of old. No single prompt captures that.
36
37	### From vibe coding to vibe investing
38
39	Inspired by software engineering: a codebase persists, and every commit builds on what came before. Code agent harnesses like Claude Code and OpenCode succeeded by building agents that embrace this pattern, exploring existing context and building on prior work. LangAlpha brings that same insight: give the agent a persistent workspace, and research naturally compounds.
40
41	In practice, you create a workspace per research goal ("Q2 rebalance", "data center demand deep dive", "energy sector rotation"). The agent interviews you about your goals and style, produces its first deliverable, and saves everything to the workspace filesystem. Come back tomorrow and your files, threads, and accumulated research are still there.
42
43	## Features Highlights
44
45	- Progressive Tool Discovery — Any MCP tools loaded as summary in context and full documentation dumped into the workspace, allowing the agent to discover and use tools truly on demand. Also supports binding json tools with skills and only expose to agent when skill is activated.
46	- Programmatic Tool Calling (PTC) — The agent writes and executes Python to process financial data from mcp servers instead of pouring raw data into the LLM context window, enabling complex multi-step analysis while dramatically reducing token waste.
47	- Financial data ecosystem — Multi-tier provider hierarchy with native tools for quick lookups and MCP servers for bulk data processing, charting, and multi-year analysis in sandboxes.
48	- Persistent workspaces — Each workspace maps to a dedicated sandbox with structured directories and a workspace notes file (`agent.md`) that compounds research across sessions and threads. A separate long-term memory store (`.agents/user/memory/`, `.agents/workspace/memory/`) persists durable user preferences and cross-sandbox knowledge, and a user-managed memo store (`.agents/user/memo/`) lets you upload PDFs and markdown research notes that the agent can read on demand.
49	- Skills for Financial Research — Pre-built
