Coding agents that forget between sessions are the problem Obsidian Mind is built to fix: the open-source vault template connects Claude Code, Codex CLI, and Gemini CLI to one Obsidian notebook so notes, links, and decisions carry over. Created by Brenno Ferrari, a senior iOS engineer in Berlin, the project is at version 8.4.0, released on 2 September 2026, and the GitHub repository lists 4.7k stars under an MIT license.

One vault for three coding agents

Obsidian Mind keeps notes, links, and decisions in Markdown so Claude Code, Codex CLI, and Gemini CLI do not open the next session from zero.

How a session keeps context

1 · Start

Inject goals, tasks, and recent changes

→

2 · Classify

Route each message to the right note

→

3 · Validate

Check links, then file the write

→

4 · Resume

The next session reads the vault

What holds up

Three CLIs share one Markdown vault. Session start loads excerpts, not the whole notebook, inside an 80,000-byte cap.

Where it slips

Without a project rule, a session can ignore the vault. Hooks are not guaranteed in Cursor, Windsurf, Copilot, or JetBrains AI. The first recall is empty.

What you need before the hooks run

Obsidian 1.12+ with the CLI enabled, Node.js 22.6+, and Git.

QMD search is optional. Without it, the agent falls back to keyword search and the Obsidian CLI.
