Claude Code + Obsidian: The AI Second Brain Playbook
Build Your AI's Long Term Memory in a Weekend
Stop re-explaining your work to Claude every morning. Ship the 5-folder vault, the CLAUDE.md that sticks, five lifecycle hooks, and three subagents in a weekend.
You open Claude Code. It forgets what you decided yesterday. It doesn’t know your project structure. Again. This is the working playbook for an Obsidian vault Claude actually reads: the 5-folder schema, the CLAUDE.md that survives long sessions, the five lifecycle hooks that re-inject context every prompt, and the three subagents that scale past 2,000 notes. Ship the vault on Saturday. By Sunday, your CLAUDE.md sticks. By next weekend, your AI remembers everything.
What You'll Build
Why every Claude session starts from zero, and what changes when you give it a vault.
The 5-folder schema that prevents the 2,000-note failure mode.
The three layers (Raw, Wiki, Schema) that started the whole wave.
Install Claude Code + Obsidian, ship the schema, run the smoke test.
Seven sections, 80-150 lines, in the load order Claude actually follows.
SessionStart, UserPromptSubmit, PostToolUse, PreCompact, Stop — wired with handler scripts.
/capture, /daily, /plan, /process-inbox, /weekly-review as five named workflows.
brag-spotter, slack-archaeologist, cross-linker — isolated contexts, three Friday runs, fifteen minutes.
PM, founder, freelancer, knowledge worker — same five folders, four daily rituals.
Three retrieval tiers and the Ollama + obsidian-copilot setup that handles the middle band.
Four maintenance failure modes and the printable diagnostic that catches them early.
A week-by-week calendar that takes you from goldfish to working memory in 30 days.
