Database Identifier

Identify database file formats via signature detection.

Quick Start

# Identify a database file
python scripts/db_identify.py unknown.db

# JSON output for piping to db-router
python scripts/db_identify.py unknown.db --json

# List all detectable formats
python scripts/db_identify.py --list-formats

Output

Human-readable:

File: course.db
Size: 12.0 KB

Format: sqlite
Version: 3.x
Confidence: high (signature detection)
DBeaver supported: Yes

JSON (for routing):

{
  "format": "sqlite",
  "version": "3.x",
  "detection_method": "signature",
  "confidence": "high",
  "dbeaver_supported": true,
  "file_info": {
    "name": "course.db",
    "size_bytes": 12288,
    "size_human": "12.0 KB"
  }
}

Typical Workflow

# 1. Identify format
python db_identify.py mystery.db --json > /tmp/db_info.json

# 2. Pass to router for extraction decision
# (handled by db-router skill)
