For OpenClaw v2026.2 | Requires obsidian and notion skills installed, and an Obsidian vault or Notion workspace.

TL;DR: Install skills: openclaw skill install obsidian notion. Configure Vault path: "vaultPath": "~/Documents/Obsidian/MyVault". Core features: automatic note organization (categorization, tagging), intelligent knowledge retrieval (semantic search), knowledge linking (auto-discover connections), daily summary (Cron-triggered). Combine with Notion sync for multi-device knowledge management.

Practice Goals

Build a personal knowledge management assistant that can:

1. Automatically organize notes
2. Intelligently retrieve knowledge
3. Generate knowledge connections
4. Create daily summaries
5. Sync to cloud services

# Obsidian Knowledge Skill

Manage your knowledge base with Obsidian.

## Features

- Create and organize notes
- Link related notes
- Search across all notes
- Generate daily summaries
- Sync with other services

## Setup

1. Set your Obsidian vault path
2. Configure sync settings
3. Define note templates

## Usage

### Create a note
User: "Create a note: Basic concepts of machine learning"
Action: Create a new note with proper frontmatter

### Search notes
User: "Search for notes about Python"
Action: Search vault and return relevant notes

### Daily summary
User: "Generate today's knowledge summary"
Action: Analyze today's notes and create summary

Configuring Vault Path

{
  "skills": {
    "obsidian-knowledge": {
      "vaultPath": "~/Documents/Obsidian/MyVault",
      "templates": {
        "daily": "Templates/Daily Note.md",
        "project": "Templates/Project.md",
        "concept": "Templates/Concept.md"
      },
      "autoSync": true,
      "defaultTags": ["inbox"]
    }
  }
}

Core Feature Implementation

Automatic Note Organization

User: Help me organize today's notes

Agent: Sure, let me look at today's notes...

[Read today's notes]
[Analyze content and tags]
[Organize structure]

I've organized today's 5 notes:

1. **Machine Learning Basics** → Move to `ML/Basics/`
2. **Python Decorators** → Move to `Python/Advanced/`
3. **Project Meeting Notes** → Move to `Projects/Meetings/`
4. **Reading Notes** → Move to `Reading/Notes/`
5. **Idea Log** → Move to `Ideas/Pending/`

Related tags and bidirectional links have been added automatically.

Intelligent Knowledge Retrieval

User: What have I learned about recursion before?

Agent: Let me search your knowledge base...

[Search obsidian-knowledge]
[Analyze relevant notes]
[Generate summary]

You've learned the following about recursion:

1. **Recursion Algorithm Principles** (2026-01-15)
   - Definition, base case, recursive call
   - Link: [[Algorithms/Recursion Principles]]

2. **Recursion vs Iteration** (2026-01-20)
   - Performance comparison, use cases
   - Link: [[Algorithms/Recursion Comparison]]

3. **Recursion in Practice: Tree Traversal** (2026-02-05)
   - Preorder, inorder, postorder traversal
   - Link: [[Data Structures/Tree Traversal]]

Would you like me to expand on any of these?

Generating Knowledge Connections

User: Help me find connections in my knowledge base

Agent: Analyzing...

Found the following knowledge connections:

**Strong connections**:
- Python → Data Analysis (8 references)
- Machine Learning → Python (6 references)
- Algorithms → Data Structures (5 references)

**Potential connections** (suggest adding links):
- Recursion → Dynamic Programming (related topics)
- Docker → Kubernetes (related tech stack)
- Design Patterns → Refactoring (practice related)

Would you like me to create these connections?

Daily Knowledge Summary

{
  "cron": [
    {
      "id": "daily-summary",
      "schedule": "0 21 * * *",
      "session": "main",
      "message": "Please analyze today's notes and generate a knowledge summary",
      "enabled": true
    }
  ]
}

Generated content:

# Daily Knowledge Summary - 2026-02-26

## Today's Learning

### New Notes (5)
1. [[Machine Learning/Basics/Linear Regression]] - Linear regression principles and implementation
2. [[Python/Tips/List Comprehension]] - Advanced list comprehension usage
3. [[Reading/Notes/Deep Work]] - Notes on "Deep Work"

### Key Takeaways
- Core of linear regression is least squares method
- List comprehension can replace map/filter combinations
- Deep work requires environment design

### To Review
- Derivation of linear regression loss function
- Advanced Python decorator usage

### Tomorrow's Plan
- Complete logistic regression learning
- Organize Python advanced notes

Notion Sync

Best Practices

1. Regular Organization

{
  "cron": [
    {
      "id": "weekly-review",
      "schedule": "0 20 * * 0",
      "session": "main",
      "message": "Please do a weekly review: 1. Organize this week's notes 2. Summarize learning 3. Plan next week's learning"
    }
  ]
}

2. Consistent Naming

Note naming conventions:
- Concepts: concept-name.md (e.g., recursion.md)
- Projects: project-name-date.md (e.g., AI-Assistant-2026-02-26.md)
- Meetings: meeting-topic-date.md (e.g., meeting-product-review-2026-02-26.md)
- Ideas: idea-short-description.md (e.g., idea-knowledge-graph-visualization.md)

3. Template System

<!-- Templates/Concept.md -->

title: {{title}}
date: {{date}}
tags: [{{tags}}]

Troubleshooting

Note Sync Failure

# Check Vault path
openclaw config get skills.obsidian-knowledge.vaultPath

# Check file permissions
ls -la ~/Documents/Obsidian/MyVault

# Check sync status
openclaw skill exec obsidian-knowledge --status

Inaccurate Retrieval

# Rebuild index
openclaw skill exec obsidian-knowledge --reindex

# Check tags
openclaw skill exec obsidian-knowledge --list-tags
