Original instructions from the publisher’s SKILL.md
# DB Skill
Query the database in non-interactive mode.
## Usage
```
/db schemas # List available schemas
/db tables # List all tables
/db describe users # Describe the users table
/db SELECT COUNT(*) FROM orders # Run raw SQL
```
## Instructions
### Determine action from $ARGUMENTS:
| Argument | Action |
|----------|--------|
| `schemas` | `{{DB_LIST_SCHEMAS_CMD}}` |
| `tables` | `{{DB_LIST_TABLES_CMD}}` |
| `describe <table>` | `{{DB_DESCRIBE_CMD}} <table>` |
| `<raw-sql>` | `{{DB_QUERY_CMD}} "<sql>"` |
### ⚠️ Always use non-interactive mode:
- PostgreSQL: `psql -c "SQL" | cat`
- MySQL: `mysql -e "SQL" | cat`
- SQLite: `sqlite3 db.sqlite "SQL"`
- MongoDB: `mongosh --eval "db.collection.find()" --quiet`
### Rules:
- Read `claude/build.md` for the DB connection string and credentials
- NEVER run destructive SQL (DROP, TRUNCATE, DELETE without WHERE) without explicit user confirmation
- NEVER commit credentials — always use env var references
- For `$DB_PATH` (SQLite): check project config files for the actual pathSkill folder
