Practitioners are wiring Anthropic’s Claude into Obsidian knowledge vaults using loop-engineering patterns so notes can be captured, drafted and checked without the model writing straight into the live file tree. The working rule is a five-stage cycle—capture, context, draft, review, commit—in which a review agent inspects every change before it lands.

Drafts stay in a worktree or transaction bundle. Only a reviewed apply touches production Markdown.

What practitioners like

State lives in Markdown. A new session can resume from files. Writes are inspectable and undoable.

What still bites

Hard rule

Claude never writes straight to the live vault.
