Overview
An open-source second brain workflow skill by eugeniughelbur for organizing notes, knowledge, and personal learning in Obsidian. Use it as a candidate workflow reference when an agent helps organize notes, links, tags, and index pages in a second-brain vault. This page treats the skill as an instruction package for an existing agent host, not as an Obsidian plugin or a grant of new permissions.
Key Features
- Open-source second brain methodology
- Index & Map of Content (MOC) creation
- Structured tagging conventions
How to Install Obsidian Second Brain Workflow
- 1Open the source repository and read its current installation instructions for your agent host.
- 2Install the complete skill folder, including any referenced files, into the host's documented skills location.
- 3Start a fresh agent session and confirm the skill is discoverable before granting vault write access.
- 4Run the first workflow in a disposable vault and review the resulting file diff.
How to Use Obsidian Second Brain Workflow
Apply it first to a copied folder, ask the agent to explain every proposed rename or link, and review the resulting structure in Obsidian before extending the method to the rest of the vault.
When to Use This Skill
Use it as a candidate workflow reference when an agent helps organize notes, links, tags, and index pages in a second-brain vault.
End-to-End Check
Apply it first to a copied folder, ask the agent to explain every proposed rename or link, and review the resulting structure in Obsidian before extending the method to the rest of the vault.
Compatibility and Safety
- A repository's organizational method is not universal. Preserve existing conventions and do not allow bulk restructuring without a recoverable backup.
- The host agent still controls tool access, filesystem scope, and confirmation behavior.
What does this skill do?
Establishes structural standards for note taking, tagging, indexing, and personal knowledge management. Use it as a candidate workflow reference when an agent helps organize notes, links, tags, and index pages in a second-brain vault. The agent host remains responsible for file access, tool availability, and confirmation before writes.
Best for
- Setting up a personal second brain in Obsidian
- Organizing research and learning materials
- Standardizing note links and index pages
How it works
- Load the complete skill in a compatible agent host.
- Apply it first to a copied folder, ask the agent to explain every proposed rename or link, and review the resulting structure in Obsidian before extending the method to the rest of the vault.
