kernl: Command for Claude Code

Schema Lookup: $ARGUMENTS

Look up the SQLite schema for the requested module(s) in this Kernl project.

Instructions

1. If the argument is "all" or "list":

   • Use Glob to find all migration files: services/kernel/src/modules/*/migrations/*.ts and services/kernel/src/modules/*/migrations.ts
   • For each module, extract table names from CREATE TABLE statements
   • Present a summary table: | Module | Tables | Migration files |

2. If the argument is a specific module name:

   • Find migration files in services/kernel/src/modules/{module}/migrations/*.ts or services/kernel/src/modules/{module}/migrations.ts
   • Read ALL migration files for that module
   • Extract and present the complete SQL schema including:
     • CREATE TABLE statements (show full DDL)
     • CREATE INDEX statements
     • ALTER TABLE statements from later migrations (show as additions)
     • CHECK constraints and their allowed values
     • Foreign key relationships
   • Also note any critical patterns:
     • Columns that are NOT NULL DEFAULT '' (use <> '' to check, not IS NOT NULL)
     • Money columns stored as INTEGER cents
     • Soft delete columns (deleted_at)

3. Format output as clean SQL with comments explaining the migration version.

4. If the module is not found, list available modules.

Important

• Migration files export arrays like export const fooMigrations: Migration[]
• Each migration has { version: number, sql: string }
• Later versions may ALTER tables from version 1
• Present the cumulative schema (all versions combined)
