SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a safe, consistent way to validate the haios_memory database schema before performing SQL operations, preventing misaligned tables or column names from causing failures.

Core Features & Use Cases

  • Schema verification: Validate table and column existence against the official schema reference.
  • Pre-query checks: Ensure query targets are valid before execution to reduce runtime errors.
  • Use Case: Before running a complex report, confirm that all referenced tables and fields exist to avoid runtime SQL errors.

Quick Start

Use the schema-ref skill to verify the haios_memory schema prior to executing a query.

FAQPage Schema
How do I verify the haios_memory database schema before running SQL queries?▼

Schema verification validates table structures and column names against the official reference before execution. This pre-query check ensures all referenced tables and fields exist in the haios_memory database, preventing runtime SQL errors caused by misaligned database objects during development or operations.

Why do my SQL queries fail when targeting the haios_memory database?▼

SQL queries fail when targeting the haios_memory database because of misaligned table or column names. Without pre-query schema verification, referencing non-existent tables or fields causes runtime errors that disrupt complex reports and database operations.

Can I check table and column existence in a memory database before execution?▼

Yes, you can check table and column existence in a memory database before execution by applying a schema validation step. This pre-query check reports verified table names, columns, and constraints using MCP-based schema info and db_query tooling to confirm query targets are valid.

What is the best way to prevent SQL errors from invalid column names in haios_memory?▼

The best way to prevent SQL errors from invalid column names is to validate the haios_memory schema before executing operations. Confirming table structures and column names against the official schema reference reduces misaligned queries and runtime failures.

Do I need MCP tooling to validate the haios_memory schema during development?▼

Yes, you need MCP-based schema info and db_query tooling to validate the haios_memory schema during development. These tools provide the verified table names, columns, and constraints required to confirm query targets before execution.
