Claude Code + Obsidian: The AI Second Brain Playbook

Claude Code can help with a project, but a fresh session may not know the decisions, conventions, and notes from the last one. Claude Code + Obsidian: The AI Second Brain Playbook offers a hands-on way to address that gap: organize useful context in an Obsidian vault and give Claude Code practical ways to find and use it.

Turn a vault into working context

Rather than treating Obsidian as a growing pile of notes, the book builds around a five-folder structure and a root-level. The aim is to make project information easier for Claude Code to consult, while giving the vault enough organization to remain useful to the person maintaining it, too.

Build the routines around the files

The playbook covers lifecycle hooks that load or update context at different points in a session, along with skills for capturing information, making daily notes, planning, and processing an inbox. It also introduces subagents and shows how recurring review workflows can bring relevant notes back into view.

Adapt the system to the work

A developer may want past decisions and project conventions close at hand; a product manager, freelancer, or knowledge worker may care more about meeting notes, client scope, or open tasks. The book discusses role-specific vault uses, then turns to maintaining a larger collection of notes and diagnosing problems when the setup stops behaving as intended.

Practical, not just conceptual

Its contents include an appendix of copy-and-paste artifacts, a vault diagnostic, and a reading list. The emphasis is on concrete files and repeatable workflows, making this a useful fit for readers already comfortable with the basics of Claude Code, Markdown, or Obsidian who want to connect those tools more deliberately.
