Claude Code turns Obsidian into second brain

This is the rare AI workflow hack that actually earns the hype. Putting Claude Code inside Obsidian turns a CLI assistant into a persistent research partner, not just a one-off code bot.

• –Anthropic already frames Claude Code as terminal-first and compatible with any IDE terminal, so Obsidian is a natural host rather than a special case.
• –The big unlock is shared memory across projects: the vault becomes a reusable context layer, so Claude can surface old decisions, docs, and research without re-asking you.
• –The payoff is real for long-running work: fewer repeated explanations, better cross-project recall, and easier synthesis from old notes.
• –The downside is that this workflow only works as well as your vault hygiene, so messy folders and fuzzy naming will quickly blunt the advantage.
