Developer Builds Automated Nightly Script to Preserve Claude AI Session Memory in Obsidian
A developer created a shell script that automatically drains daily Claude Code conversation logs into an Obsidian vault each night, solving the problem of lost context between independent AI sessions. The system commits logs to a private Git repository and generates a desktop briefing, acting as a persistent external memory across multiple parallel projects. Three real-world failures — a mid-run sleep freeze, a double-execution Git conflict on June 10, and a full-day timeout failure on June 13 — exposed critical weaknesses in the original single-slot design. Each incident forced a specific fix, resulting in a triple-layered architecture combining multi-slot re-firing, caffeinate-based sleep prevention, and idempotent retries using step markers. The developer notes the reliability improvements emerged entirely from live failures rather than upfront design planning.
