Claude Code That Remembers Last Week

If, like me, you feel that each Claude Code session starts blank even after saving everything in a .md file, then this might be useful for you.

We are an Outbound Lead Generation agency, and recently we've been managing over 10+ active client campaigns simultaneously within a terminal using Claude code.

Each time a new terminal session begins, we spend 10 to 15 minutes rebuilding context. This amounts to an hour of lost productivity daily.

Additionally, if I overlooked a detail, Claude would simply agree with the most recent version I provided, leading the story to drift across sessions without anyone noticing.

So we built a knowledge loop. Claude now remembers across sessions.

Here is the stack.
- Claude Code runs as normal.
- When I close a session, a SessionEnd hook fires the Claude Agent SDK, which distills the transcript into a markdown daily log.
- A Python compiler turns those logs into wikilinked concept articles inside my Obsidian vault.
- A SessionStart hook injects the index into every new session. MCP memory serves entity lookups on demand.
- A weekly launchd cron promotes recurring patterns into playbooks.
- The whole vault is git-backed to a private GitHub repo.

Claude now opens every session already knowing what we worked on last week. Zero re-explaining.

Let me know if you are interested and I will share the GitHub.
