Obsidian Integration

Expert guidance for integrating Claude workflows with Obsidian vault, including note creation, task management, and knowledge organization using Obsidian's markdown-based system.

When to Use This Skill

• Creating notes during development sessions with Claude
• Tracking tasks and TODOs in Obsidian
• Documenting decisions and solutions discovered with Claude
• Building a knowledge base of project insights
• Organizing research findings from Claude sessions
• Creating meeting notes or session summaries

Supporting Files

This skill is split across several files. Load the relevant file when needed:

• best-practices.md - MOCs, properties, organization philosophy, dump tag requirements
• templates.md - Note templates: session, technical, task, analysis planning, thematic reference, TODO, HOME.md
• organization-patterns.md - Home MOC, Project MOC, TODO consolidation, archive strategy, cross-project linking
• vault-management.md - Vault reorganization, session consolidation, link management, project directory setup, brain dump handling
• reference.md - Obsidian markdown syntax, bash helpers, plugins, Claude integration patterns, troubleshooting
• cli-reference.md - Obsidian CLI (1.12+) command reference, replaces many bash patterns
• changelog.md - Version history

Core Principles

1. Prefer CLI - Use obsidian CLI commands (1.12+) over bash/cat patterns when possible. See cli-reference.md
2. Vault Location - Use $OBSIDIAN_VAULT environment variable for direct file access; CLI uses vault=<name> option
3. Always Ask User for Note Placement - Never decide where to save notes without asking the user first. Show vault structure, suggest options, and let the user choose.
4. Atomic Notes - Each note focuses on a single concept or topic
5. Linking - Use wikilinks [[note-name]] to connect related ideas
6. Tags - Organize with hierarchical tags like #project/feature
7. Tasks - Use checkbox syntax for actionable items
8. Timestamps - Include dates for temporal context

Essential Rules

Rule 1: Never Assume Note Placement

CRITICAL: When creating ANY note in Obsidian, ALWAYS ask the user where they want it saved. Never decide the location yourself, even if it seems obvious.

Why: The user knows how their vault is organized. Assuming a location means they'll need to reorganize later.

Workflow for ANY note creation:

1. Show current vault structure to help user decide
2. Suggest options (root level, specific folder, custom path) -- do NOT decide
3. Get user input before writing anything
4. Create in chosen location

Only exception: Project session notes when .claude/project-config already specifies the location from a previous user choice.

Golden Rule: If you're about to write a file to the Obsidian vault, STOP and ask the user where it should go first.

Rule 2: Always Include Dump Tag in Session Notes

ALWAYS include the dump tag in session/daily notes. This is essential for:

• Filtering all session notes across projects: tag:#dump
• Archiving workflows with /consolidate-notes
• Separating working notes from permanent documentation

Python template for new session files:

f.write("---\n")
f.write("type: session\n")
f.write(f"project: {PROJECT_NAME}\n")
f.write(f"date: {date_str}\n")
f.write("tags:\n")
f.write("  - session\n")
f.write("  - dump\n")  # REQUIRED
f.write("status: completed\n")
f.write("---\n\n")

Rule 3: Always Add Properties (Frontmatter)

Every note must have YAML frontmatter with at minimum:

---
type: session | planning | reference | todo | moc | development | analysis
project: project-name
status: active | in-progress | completed | archived
tags:
  - relevant-tags
created: YYYY-MM-DD
---

For the full property schema, see best-practices.md.

Rule 4: Use MOCs Over Deep Folders

• Keep folder structure flat (2-3 levels max)
• Use Maps of Content (MOC) notes as navigation hubs
• Keep MOCs under 25 items
• Create sub-MOCs when sections grow too large
• Use properties and tags for topic categorization, not folders

For detailed MOC guidance, see best-practices.md.

Vault Configuration

Environment Setup

# Check vault location
echo $OBSIDIAN_VAULT
# Should return something like: /Users/username/Documents/Notes

# If not set, add to ~/.zshrc or ~/.bashrc
export OBSIDIAN_VAULT="/path/to/your/vault"

Obsidian CLI (1.12+)

Obsidian now ships with a native CLI (obsidian). Prefer CLI commands over bash patterns for creating, reading, appending, and searching notes.

# Verify CLI is available
obsidian version

# List vaults
obsidian vaults verbose

# Target a specific vault
obsidian files vault="My Vault"

For the full CLI command reference, see cli-reference.md.

Key Workflows

Creating a Note

1. Check vault is accessible (obsidian vault or echo $OBSIDIAN_VAULT)
2. Show vault structure to user (obsidian folders or obsidian files)
3. Ask where to save the note
4. Create with proper frontmatter (type, project, tags, created date)
5. Include dump tag if it's a session note
6. Add wikilinks to related notes

Using CLI:

obsidian create name="my-note" path="projects/my-note.md" template="session" open
# Or with inline content:
obsidian create name="my-note" content="---\ntype: session\ntags:\n  - dump\n---\n\n# Content"

Using bash (for complex multi-line content):

cat > "$OBSIDIAN_VAULT/projects/my-note.md" <<'EOF'
---
type: session
tags:
  - dump
---
# Content
EOF

For note templates, see templates.md.

Creating a Session Summary

Used by /safe-exit and /safe-clear commands:

1. Read project config from .claude/project-config for vault path
2. Create note in project's session-saves/ directory
3. Include frontmatter with type: session, dump tag
4. Document: context, summary, decisions, action items, code references
5. Link to related notes

Consolidating Session Notes

When session folder has 5+ notes or at project milestones:

1. Review all session notes, identify themes
2. Create thematic reference notes (by topic, not date)
3. Extract TODOs to project TO-DOS.md
4. Archive processed sessions to archived/daily/
5. Update project HOME.md and MOCs

For the full consolidation workflow, see vault-management.md.

Vault Reorganization

When restructuring the vault:

1. Document target structure
2. Create new folders first
3. Move files and folders
4. Update all links systematically
5. Run broken link detection
6. Verify with tree command

For detailed reorganization steps, see vault-management.md.

Standard Project Structure

project-name/
├── TO-DOS.md
├── session-saves/
├── archived/
│   ├── daily/
│   └── monthly/
└── [project-specific folders]

Obsidian Syntax Quick Reference

[[Note Name]]              # Wikilink
[[Note Name|Display Text]] # Wikilink with alias
[[Note#Heading]]           # Link to heading
#tag  #project/feature     # Tags
- [ ] Task to do           # Task
- [x] Completed task       # Done task
> [!note]                  # Callout
> Content here

For full syntax reference, see reference.md.

Remember: The goal is to build a searchable, linked knowledge base that grows with each Claude session. Start simple, add structure as needed.
