This skill enables the management of Obsidian vaults as living systems where sources update existing pages and scheduled agents maintain structure. It is designed for users who need to automate knowledge synthesis, from logging development work and tracking decisions to maintaining kanban boards.
The system includes a research toolkit for capturing findings from YouTube, podcasts, and various AI search engines, allowing users to bootstrap new vaults or synchronize operating rules across different Claude surfaces.
Follow the documented setup, then try a first task.
Installs: Complete obsidian-second-brain plugin: all 48 commands, skill manual, session-context hook, optional background agent, and vault MCP server. · Claude Code
Enter both commands inside a Claude Code session.
/plugin marketplace add eugeniughelbur/obsidian-second-brain /plugin install obsidian-second-brain@obsidian-second-brain
In ~/.claude/settings.json, add OBSIDIAN_VAULT_PATH to the env section, replacing /path/to/your/vault with your actual vault path.
Restart Claude Code, open your vault, and enter this command in the agent session.
/obsidian-second-brain:obsidian-init
Installs: Classic obsidian-second-brain installation with bare slash commands, the skill, and the session-context hook; research setup is optional. · Claude Code
Run this command in a terminal. The installer clones the skill, installs slash commands, registers the session-context hook, and offers optional research setup.
curl -fsSL https://raw.githubusercontent.com/eugeniughelbur/obsidian-second-brain/main/scripts/quick-install.sh | bash
Restart Claude Code, open your vault, and enter this command in the agent session to generate its operating manual.
/obsidian-init
Installs: Classic obsidian-second-brain installation with bare slash commands, the skill, and the session-context hook; research setup is optional. · Claude Code
Run these commands in a terminal in order, replacing /path/to/your/vault with your actual vault path.
git clone https://github.com/eugeniughelbur/obsidian-second-brain ~/.claude/skills/obsidian-second-brain bash ~/.claude/skills/obsidian-second-brain/install.sh bash ~/.claude/skills/obsidian-second-brain/scripts/setup.sh "/path/to/your/vault"
Restart Claude Code, open your vault, and enter this command in the agent session.
/obsidian-init
Installs: Complete agent-skills build of obsidian-second-brain: command skills and the shared obsidian-core toolkit installed under the vault's .agents/skills/ directory. · Google Antigravity, Codex CLI, OpenCode, GitHub Copilot CLI
Run from: Run the build and copy from the cloned obsidian-second-brain repository.
Run these commands in a terminal to clone the repository and build the Agent Skills distribution.
git clone https://github.com/eugeniughelbur/obsidian-second-brain cd obsidian-second-brain bash scripts/build.sh --platform agent-skills
From the repository directory, run this terminal command, replacing /path/to/your/vault with your actual vault path.
cp -R dist/agent-skills/skills/. /path/to/your/vault/.agents/skills/
Use your vault as the working directory, or set OBSIDIAN_VAULT_PATH to its path, so the installed skills can resolve the vault root.
Uses obsidian-second-brain
Use the obsidian-second-brain skill to orient yourself to my vault at <vault-path>. Read its _CLAUDE.md if present, scan its Markdown structure, and read 2–3 existing notes. Give me a brief overview of its folders, templates, naming conventions, frontmatter, and writing style. Do not modify any files.
