# Obsidian Core Workflow A: Vault Operations

## Overview
Primary workflow for Obsidian plugin development: manipulating notes, handling frontmatter, and working with the vault file system.

## Prerequisites
- Completed `obsidian-install-auth` setup
- Understanding of Obsidian's file structure
- Valid development vault configured

## Instructions

### Step 1: Working with Files (TFile)

### Step 2: Frontmatter Operations

### Step 3: Link and Tag Operations

### Step 4: Search and Query

For full implementation details and code examples, load:
`references/implementation-guide.md`

## Output
- File operations for create, read, update, delete
- Frontmatter parsing and modification
- Link and tag traversal
- Search and query capabilities

## Error Handling
| Error | Cause | Solution |
|-------|-------|----------|
| File not found | Path incorrect | Verify with `getAbstractFileByPath` |
| Permission denied | File locked | Check if file is open in editor |
| YAML parse error | Invalid frontmatter | Validate YAML syntax |
| Circular links | Recursive backlinks | Track visited files |
