 "title": "Feed facts into memory from scripts and cron",
 "page_title": "How to feed facts into memory from scripts and cron with Lemmalog",
 "summary": "Use the headless lemmalog-cli to observe facts and run queries from shell scripts or scheduled jobs.",
 "who": "An operator with a scheduled job or shell pipeline that produces structured facts and needs them in a shared memory for later agent queries.",
 "problem": "Agents cannot always reach MCP, and scheduled jobs need a way to write to the same memory without an interactive session.",
 "outcome": "A script writes triples to the snapshot with lemmalog-cli observe, and a later step reads derived answers with lemmalog-cli query.",
 "steps": [
  "Run `cargo build --release` to produce the lemmalog-cli binary. (inferred, check the README)",
  "Choose one snapshot path and export it: `export LEMMALOG_MCP_PATH=/tmp/lemmalog.snapshot`. (inferred, check the README)",
  "Write facts from your script: `LEMMALOG_MCP_PATH=/tmp/lemmalog.snapshot lemmalog-cli observe --facts 'S --rel--> O'`, replacing S, rel and O with real values.",
  "Read derived answers: `LEMMALOG_MCP_PATH=/tmp/lemmalog.snapshot lemmalog-cli query --goal 'current(\"s\", R, O)'`.",
  "Route every writer through the CLI and keep MCP-based writers out of the same snapshot while the job runs."
 ],
 "agent_prompt": "Using lemmalog-cli with snapshot <snapshot path>, observe the facts in <input file> and then run a query for <entity>. Expected output: the observe report with any dropped lines and the query results. Verify that no line was silently dropped.",
 "agents": [
  "any"
 ],
 "difficulty": "Advanced",
 "time": "1 hour",
 "basis": "readme",
 "caveat": "The README says the MCP server and CLI hold separate in-process copies, so concurrent writes to one snapshot can conflict.",
 "category": "Software and DevOps",
 "tags": [

 ],
 "lang": "rust",
 "requirements": [
  "Rust toolchain with cargo, and a clone of the lemmalog repo",
  "Claude Code (or Kimi CLI) installed if you want MCP tools",
  "A writable path for the memory snapshot, for example /tmp/lemmalog.snapshot or the default ~/.lemmalog/memory.snap"
