Obsidian vault gives Claude Code persistent memory

Claude Code's biggest real-world limitation isn't capability — it's amnesia. Every session starts cold, forcing developers to re-establish context manually each time.

• –The core mechanic is dead simple: drop a CLAUDE.md in your Obsidian vault root and Claude Code reads it on every session start, effectively "remembering" your conventions, standards, and project state
• –Obsidian works here because it stores all notes as plain markdown files — no proprietary format, no sync lock-in, no special integration needed beyond filesystem access
• –Advanced extensions include a running memory.md for project state, the claudesidian pre-built vault template, and the claudian plugin that embeds Claude Code directly inside Obsidian
• –This fills the gap until Anthropic ships native persistent memory — and may remain useful after, since user-controlled context is more transparent and portable than opaque AI memory
• –The pattern generalizes: any agent that reads a project-level config file at startup can use this approach, making it transferable to other agentic coding tools
