name: db description: Query the database — list schemas, tables, describe a table, or run SQL. Accepts arguments like schemas, tables, describe <table>, or raw SQL.

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 path
