Your AI Coding Agent Forgets Everything — Fix It With a Free Obsidian Vault

A developer has released the Verified Memory Vault, a free Obsidian-based system that gives AI coding agents persistent memory across sessions. The vault uses a three-rule method—capture, daily notes, and durable facts—plus two Python scripts to check memory health and prevent accidental deletion. It is licensed CC BY 4.0 and available for download from GitHub.

Every AI coding agent starts every session with amnesia. The repository is there, the instructions are there — but the knowledge from yesterday's session is gone: the workaround for that build error, your preference about naming, the decision you made last week. So you explain it again. And again. The fix is almost embarrassingly simple: give the agent a place to write things down — and a way to check that the memory is actually healthy. CLAUDE.md at the start of every session. What is inside: 00 Inbox — everything lands here first capture, don't sort 01 Daily — one note per session: what was done, decided, blocked 02 Templates — daily note templates, English and German CLAUDE.md — the boot file every agent reads first: rules and memory protocol MEMORY.md — the durable memory: append-only, dated, one line per fact tools/memory check.py — scores memory health on demand: protocol violations, dead links, bloat, inbox pressure. One command, honest report. tools/memory guard.py — an optional git pre-commit hook that refuses the commit that deletes your agent's brain the documented way agent memories die The whole method is three rules: Capture, don't sort. New notes land in the inbox; sorting happens in the daily note, not while capturing. Every session leaves a daily note. So the next session resumes cold — without asking you where you left off. Promote durable facts into MEMORY.md. If a fact will matter in a later session, it belongs there: dated, one line, never rewritten. Why "self-checking" matters: folder structures rot silently. Memory gets bloated, links die, entries lose their dates — and nobody notices until the agent's context is full of junk. Run python3 tools/memory check.py and you get a score, a list of concrete problems, and an exit code your CI or agent loop can act on. If you keep the vault in git recommended , the guard hook blocks mass deletions of MEMORY.md before they happen. Setup takes ten minutes. Install Obsidian free , download the vault, open the folder as a vault — daily notes and templates are already preconfigured, no plugins to install. Claude Code reads CLAUDE.md automatically; for other agents Codex, Gemini CLI, … point them at the file or copy it to their boot file, e.g. AGENTS.md . At the end of a session: fill the daily note, promote the durable facts, run the check once. That is the whole habit. And what it is not — honestly: not a plugin collection no community plugins, no vector database , not an autonomous system it is a structure with two small scripts, not a magic product , and not a replacement for your code repository — it is memory about the work. That is exactly why it keeps working: nothing to maintain, everything auditable in ten minutes. Why the license matters: many “AI vaults” in circulation are non-commercial.

If you already run a note system for yourself, Second Brain Starter https://secondbrainstarter.github.io/ is the human-side companion: the same three-folder philosophy, built for people who want a working note system in ten minutes.
