 "repo_url": "https://github.com/SodaMem/SodaMem",
 "repo_slug": "sodamem-sodamem",
 "title": "Build a chatbot that updates facts when users change them",
 "page_title": "How to build a chatbot that updates facts when users change them with Soda Mem",
 "summary": "Ingest a user message and recall the latest version of a fact, with the older version kept readable.",
 "who": "A Python developer building a personal assistant whose users change jobs, homes or preferences over time.",
 "problem": "Most memory stores overwrite old values, so the assistant gives outdated answers after a user changes their mind.",
 "outcome": "The assistant returns a prompt-ready memory block showing the current fact, with citations to the turn it came from.",
 "steps": [
  "Run `pip install \"sodamem[chroma,llm]\"` to install Soda Mem.",
  "Set SODAMEM_LLM_API_KEY in your environment for the extractor.",
  "Create a script that calls Soda Mem.open(\"./data\", extractor=FactEventExtractorV2(create_provider_from_env())) and calls mem.ingest with a message that changes a fact.",
  "Call mem.build_context with a question about that fact and print block.text and block.citations."
 ],
 "agent_prompt": "In the SodaMem repo at <repo path>, write a Python script that ingests a message for user u1 saying the user moved to a new city, then calls build_context for where the user lives. Expected output: the new city in block.text with citations. Verify that the old city does not appear as the current answer.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "Ingest needs an LLM provider through the extractor, so the first run depends on a valid API key, while the recall step makes zero LLM calls.",
 "category": "Software and DevOps",
 "tags": [
  "Software and DevOps"
 ],
 "lang": "python",
 "requirements": [
  "Python environment with pip available",
  "An LLM provider API key set as SODAMEM_LLM_API_KEY, needed only for ingest",
  "Docker or a running daemon is not required for the Python path, but coding tools need `sodamem daemon ensure` first"
