# Memory Export/Import Scripts

Share your claude-mem knowledge with other users! These scripts allow you to export specific memories (observations, sessions, summaries, and prompts) and import them into another claude-mem installation.

## Use Cases

- **Share Windows compatibility knowledge** with Windows users
- **Share bug fix patterns** with contributors
- **Share project-specific learnings** across teams
- **Backup specific memory sets** for safekeeping

## How It Works

### Export Script

Searches the database using **hybrid search** (combines ChromaDB vector embeddings with FTS5 full-text search) and exports all matching:
- **Observations** - Individual learnings and discoveries
- **Sessions** - Session metadata
- **Summaries** - Session summaries
- **Prompts** - User prompts that led to the work

Output is a portable JSON file that can be shared.

> **Privacy Note:** Export files contain all matching memory data in plain text. Review exports before sharing to ensure no sensitive information (API keys, passwords, private paths) is included.

### Import Script

Imports memories with **duplicate prevention**:
- Checks if each record already exists before inserting
- Skips duplicates automatically
- Maintains data integrity with transactional imports
- Reports what was imported vs. skipped

**Duplicate Detection Strategy:**
- **Sessions**: By `claude_session_id` (unique)
- **Summaries**: By `sdk_session_id` (unique)
- **Observations**: By `sdk_session_id` + `title` + `created_at_epoch` (composite)
- **Prompts**: By `claude_session_id` + `prompt_number` (composite)

## Usage

### Export Memories

```bash
# Export all Windows-related memories
npx tsx scripts/export-memories.ts "windows" windows-memories.json

# Export bug fixes
npx tsx scripts/export-memories.ts "bugfix" bugfixes.json

# Export specific feature work
npx tsx scripts/export-memories.ts "progressive disclosure" progressive-disclosure.json
```

**Parameters:**
1. `<query>` - Search query (uses hybrid semantic + full-text search)
2. `<output-file>` - Output JSON file path
3. `--project=name` - Optional: filter results to a specific project

**Example Output:**
```
🔍 Searching for: "windows"
✅ Found 54 observations
✅ Found 12 sessions
✅ Found 12 summaries
✅ Found 7 prompts

📦 Export complete!
📄 Output: windows-memories.json
📊 Stats:
   • 54 observations
   • 12 sessions
   • 12 summaries
   • 7 prompts
```

### Import Memories

```bash
# Import from an export file
npx tsx scripts/import-memories.ts windows-memories.json
```

**Parameters:**
1. `<input-file>` - Input JSON file (from export script)

**Example Output:**
```
📦 Import file: windows-memories.json
📅 Exported: 2025-12-10T23:45:00.000Z
🔍 Query: "windows"
📊 Contains:
   • 54 observations
   • 12 sessions
   • 12 summaries
   • 7 prompts

🔄 Importing sessions...
   ✅ Imported: 12, Skipped: 0
🔄 Importing summaries...
   ✅ Imported: 12, Skipped: 0
🔄 Importing observations...
   ✅ Imported: 54, Skipped: 0
🔄 Importing prompts...
   ✅ Imported: 7, Skipped: 0

✅ Import complete!
📊 Summary:
   Sessions:     12 imported, 0 skipped
   Summaries:    12 imported, 0 skipped
   Observations: 54 imported, 0 skipped
   Prompts:      7 imported, 0 skipped
```

### Re-importing (Duplicate Prevention)

If you run the import again on the same file, duplicates are automatically skipped:

```
🔄 Importing sessions...
   ✅ Imported: 0, Skipped: 12  ← All skipped (already exist)
🔄 Importing summaries...
   ✅ Imported: 0, Skipped: 12
🔄 Importing observations...
   ✅ Imported: 0, Skipped: 54
🔄 Importing prompts...
   ✅ Imported: 0, Skipped: 7
```

## Sharing Memories

### For Export Authors

1. **Export your memories:**
   ```bash
   npx tsx scripts/export-memories.ts "windows" windows-memories.json
   ```

2. **Share the JSON file** via:
   - GitHub gist
   - Project repository (`shared-memories/`)
   - Direct file transfer
   - Package in releases

3. **Document what's included:**
   - What query was used
   - What knowledge is contained
   - Who might benefit from it

### For Import Users

1. **Download the export file** to your local machine

2. **Review what's in it** (optional):
   ```bash
   cat windows-memories.json | jq '.totalObservations, .totalSessions'
   ```

3. **Import into your database:**
   ```bash
   npx tsx scripts/import-memories.ts windows-memories.json
   ```

4. **Verify import** by searching:
   ```bash
   curl "http://localhost:37777/api/search?query=windows&format=index&limit=10"
   ```

## JSON Export Format

```json
{
  "exportedAt": "2025-12-10T23:45:00.000Z",
  "exportedAtEpoch": 1733876700000,
  "query": "windows",
  "totalObservations": 54,
  "totalSessions": 12,
  "totalSummaries": 12,
  "totalPrompts": 7,
  "observations": [ /* array of observation objects */ ],
  "sessions": [ /* array of session objects */ ],
  "summaries": [ /* array of summary objects */ ],
  "prompts": [ /* array of prompt objects */ ]
}
```

## Safety Features

✅ **Duplicate Prevention** - Won't re-import existing records
✅ **Transactional** - All-or-nothing imports (database stays consistent)
✅ **Read-only Export** - Export script opens database in read-only mode
✅ **Dependency Ordering** - Sessions imported before observations/summaries
✅ **Validation** - Checks database exists before starting

## Advanced Usage

### Export by Project

```bash
# Export only claude-mem project memories
npx tsx scripts/export-memories.ts "bugfix" bugfixes.json --project=claude-mem

# Export all memories for a specific project
npx tsx scripts/export-memories.ts "" all-project.json --project=my-app
```

### Export by Type

```bash
# Export only discoveries
npx tsx scripts/export-memories.ts "type:discovery" discoveries.json

# Export only bug fixes
npx tsx scripts/export-memories.ts "type:bugfix" bugfixes.json
```

### Export by Date Range

You can filter the export after exporting:

```bash
# Export all memories, then filter manually with jq
npx tsx scripts/export-memories.ts "" all-memories.json
cat all-memories.json | jq '.observations |= map(select(.created_at_epoch > 1700000000000))' > recent-memories.json
```

### Combine Multiple Exports

```bash
# Export different topics
npx tsx scripts/export-memories.ts "windows" windows.json
npx tsx scripts/export-memories.ts "linux" linux.json

# Import both
npx tsx scripts/import-memories.ts windows.json
npx tsx scripts/import-memories.ts linux.json
```

## Troubleshooting

### Database Not Found

```
❌ Database not found at: /Users/you/.claude-mem/claude-mem.db
```

**Solution:** Make sure claude-mem is installed and has been run at least once.

### Import File Not Found

```
❌ Input file not found: windows-memories.json
```

**Solution:** Check the file path. Use absolute paths if needed.

### Partial Import

If import fails mid-way, the transaction is rolled back - your database remains unchanged. Fix the issue and try again.

## Contributing Memory Sets

If you've exported valuable knowledge that others might benefit from:

1. Create a PR to the `shared-memories/` directory
2. Include a README describing what's in the export
3. Tag with relevant keywords (windows, linux, bugfix, etc.)
4. Community members can then import your knowledge!
