Task: Initialize Project Memory

Set up Obsidian vault and populate it with existing codebase knowledge.

When to Use

• When setting up context memory for a new project
• When enabling AI-assisted development with persistent knowledge
• When migrating project knowledge to Obsidian format
• When starting a project that needs pattern tracking

Quick Start

1. Install dependencies (

   pip install python-frontmatter

   )
2. Run

   python skills/context-memory/utils/init_vault.py

3. Verify vault created at

   docs/memory/

4. Optionally configure

   PRISM_OBSIDIAN_VAULT

   for custom location

Prerequisites

• Python 3.10+ installed
• Obsidian installed (optional, for browsing)

Steps

1. Install Dependencies

cd .prism
pip install python-frontmatter

2. Initialize Vault

python skills/context-memory/utils/init_vault.py

This creates:

• docs/memory/

  vault folder (at project root)
• Folder structure (Files, Patterns, Decisions, Commits, etc.)
• Index files (README, File Index, Pattern Index, Decision Log)

• .gitignore

  configuration

Default location:

docs/memory/

(one level up from

.prism/

)

Custom location: Set

PRISM_OBSIDIAN_VAULT

in

.env

file

3. Verify Setup

# Check vault exists (from project root)
ls -lh docs/memory/

# Check structure
ls docs/memory/PRISM-Memory/

# View stats
python -c "from skills.context-memory.utils.storage_obsidian import get_memory_stats; print(get_memory_stats())"

4. Enable Hooks

Create/update

.claude/hooks.json

:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Edit|Write",
        "hooks": [
          {
            "type": "command",
            "command": "python ${CLAUDE_PLUGIN_ROOT}/hooks/capture-file-context-obsidian.py"
          }
        ]
      },
      {
        "matcher": "Bash",
        "hooks": [
          {
            "type": "command",
            "command": "python ${CLAUDE_PLUGIN_ROOT}/hooks/capture-commit-context-obsidian.py"
          }
        ]
      }
    ]
  }
}

5. Interactive Analysis (Populate Initial Context)

Ask Claude Code to analyze key files:

"Please analyze the main entry points and core modules in this project"

Claude will:

• Read and analyze files using native tools
• Create markdown notes in the vault
• Organize by file path structure
• Capture patterns and architecture decisions

6. Enable REST API (Optional but Recommended)

For instant synchronization with Obsidian:

1. Install Local REST API plugin in Obsidian
2. Get API key from plugin settings
3. Configure

   .prism/.env

   :

   cd .prism
   cp .env.example .env
   # Edit .env and replace 'your-api-key-here' with your actual key
   

4. Test:

   python skills/context-memory/utils/obsidian_rest_client.py

Security: Never commit

.env

- it contains your personal API key!

Benefits: Instant updates in Obsidian, 10x faster search

See:

skills/context-memory/reference/obsidian-rest-api.md

for details

7. Open in Obsidian (Optional)

1. Launch Obsidian
2. File > Open vault
3. Select

   docs/memory/

   (from project root)
4. Explore the knowledge graph

8. Verify Results

# Check stats
python -c "from skills.context-memory.utils.storage_obsidian import get_memory_stats; import json; print(json.dumps(get_memory_stats(), indent=2))"

# Test search
python -c "from skills.context-memory.utils.storage_obsidian import recall_query; results = recall_query('authentication'); print(f'Found {len(results)} results')"

# Browse notes (from project root)
ls docs/memory/PRISM-Memory/Files/
ls docs/memory/PRISM-Memory/Patterns/

9. Automatic Capture is Now Active

With hooks enabled, all future edits are captured automatically:

• File changes → Notes in

  Files/

• Git commits → Notes in

  Commits/

• Context builds as you code
• No manual intervention needed

Expected Results

After completion:

• Vault contains markdown notes for analyzed files
• Notes organized by file path structure
• Full-text search available
• Visual knowledge graph in Obsidian
• Hooks capture future changes automatically

Vault Structure

├── Files/              # File analyses (mirrors source structure)
│   └── src/
│       └── auth/
│           └── jwt.ts.md
├── Patterns/           # Code patterns by category

Troubleshooting

Vault Not Found

❌ Vault does not exist: docs/memory

Solution: Run

python skills/context-memory/utils/init_vault.py

from

.prism/

directory

Import Error

ModuleNotFoundError: No module named 'frontmatter'

Solution: Run

pip install python-frontmatter

Hook Not Capturing Files

Check:

• Verify hook paths in

  .claude/hooks.json

• Ensure vault exists at

  docs/memory/

  (from project root)
• Confirm file is source code (hooks skip .md, .json, etc.)
• Review

  .prism-memory-log.txt

  for errors
• Check REST API status in

  .prism-memory-api-log.txt

  (if using API)

Notes Not Appearing in Obsidian

Solution:

• Close and reopen vault in Obsidian
• Check vault path matches in

  .env

• Verify files exist in filesystem

Success Criteria

• Vault initialized with folder structure
• Can view markdown notes in filesystem
• Search returns relevant results
• Hooks enabled for automatic capture
• Obsidian opens vault successfully (optional)

Next Steps

1. Browse vault in Obsidian to see knowledge graph
2. Use graph view (Ctrl+G) to visualize connections
3. Query context:

   recall_query("authentication patterns")

4. Continue development - context captures automatically
5. Link notes manually for better knowledge organization

Benefits

• Human-readable: Browse notes in any text editor or Obsidian
• Visual: Graph view shows code relationships
• Searchable: Full-text search across all notes
• Linkable: Connect concepts with wikilinks
• Git-friendly: Markdown files work with version control
