Migrate Validate

Validate all pending database migrations for correctness, safety, and adherence to best practices.

When to use

Before applying migrations to catch issues early -- foreign key references to non-existent tables, missing rollback SQL, destructive operations without safeguards, and naming convention violations.

Steps

1. Find pending migrations -- use Glob to list all migration files, cross-reference with applied history via mcp__plugin_ruflo-core_ruflo__memory_search --namespace migrations (or memory_list) to identify pending ones. The memory_* tool family routes by namespace; agentdb_hierarchical-* does NOT (it routes by tier), so use memory_* here.
2. Parse SQL -- use Read to load each pending .up.sql and .down.sql file and parse the SQL statements
3. Check foreign keys -- verify that all REFERENCES targets exist in the current schema or in prior migrations (both applied and pending)
4. Check NOT NULL defaults -- verify that any ADD COLUMN with NOT NULL has a DEFAULT value
5. Check rollback completeness -- verify every CREATE/ALTER in the UP file has a corresponding DROP/ALTER in the DOWN file
6. Flag destructive ops -- warn on DROP TABLE, DROP COLUMN, TRUNCATE without explicit confirmation
7. Check idempotency -- verify IF EXISTS / IF NOT EXISTS is used for safety
8. Check naming -- verify table names are plural, column names are snake_case, index names follow idx_table_column convention
9. Store validation patterns -- two paths (per ruflo-cost-tracker ADR-0001 dual-path pattern):
   • Pattern store (typed, recommended): mcp__plugin_ruflo-core_ruflo__agentdb_pattern-store with type: 'migration-validation'. No namespace arg — ReasoningBank routes it.
   • Plain store (namespace-routable): mcp__plugin_ruflo-core_ruflo__memory_store --namespace migrations for validation results tied to a specific migration number.
10. Report -- display: errors (must fix), warnings (should fix), info (suggestions), with file path and line number for each issue
