# Test custom port
PORT=37778
curl -s http://127.0.0.1:$PORT/health
```

## Database Queries

```bash
# Observation count
sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations;"

# Session count
sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM sessions;"

# Recent observations
sqlite3 ~/.claude-mem/claude-mem.db "SELECT created_at, type, title FROM observations ORDER BY created_at DESC LIMIT 10;"

# Recent sessions
sqlite3 ~/.claude-mem/claude-mem.db "SELECT created_at, request FROM sessions ORDER BY created_at DESC LIMIT 5;"

# Database size
du -h ~/.claude-mem/claude-mem.db

# Database integrity check
sqlite3 ~/.claude-mem/claude-mem.db "PRAGMA integrity_check;"

# Projects in database
sqlite3 ~/.claude-mem/claude-mem.db "SELECT DISTINCT project FROM observations ORDER BY project;"
```

## Configuration

```bash
# View current settings
cat ~/.claude-mem/settings.json
cat ~/.claude/settings.json

# Change worker port
echo '{"env":{"CLAUDE_MEM_WORKER_PORT":"37778"}}' > ~/.claude-mem/settings.json

# Change context observation count
# Edit ~/.claude/settings.json and add:
{
  "env": {
    "CLAUDE_MEM_CONTEXT_OBSERVATIONS": "25"
  }
}

# Change AI model
{
  "env": {
    "CLAUDE_MEM_MODEL": "claude-haiku-4-5"
  }
}
```

## Plugin Management

```bash

# View package.json
cat package.json
```

## Port Diagnostics

curl -v http://127.0.0.1:37777/health
```
