schema-gen

schema-gen is a skill for Claude Code from GlamgarOnDiscord/claude-saas-blueprint. It costs 23 tokens per session (454 once invoked), scanned A, original, MIT.

A database setup generator that creates a data schema, migration files, TypeScript types, validation, and a basic repository for an entity such as an invoice or project.

In plain words
What is it for?
Use it to add a new entity to a project using Drizzle, Prisma, or SQLAlchemy. It prepares the database changes and the code needed to create, read, update, and delete records.
Why use it?
It removes the repetitive work of connecting database structure to application code. It also applies common fields, relationships, indexes, and soft deletion when appropriate.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

schema-gen scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Arguments

  • entity : Nom de l'entité (ex: "Invoice", "Project")
  • fields : Description des champs en langage naturel

Instructions

1. Détection ORM

Lire .claude/memory/stack.md ou détecter :

  • drizzle.config.ts → Drizzle ORM
  • schema.prisma → Prisma
  • alembic/ → SQLAlchemy
  • Sinon → demander à l'utilisateur

2. Génération du Schema

Créer le fichier de schema avec :

  • Tous les champs demandés avec types appropriés
  • id : UUID v7 par défaut (ordonné chronologiquement)
  • organizationId : FK pour multi-tenancy (sauf si explicitement exclu)
  • createdAt : timestamp, default now
  • updatedAt : timestamp, auto-update
  • deletedAt : timestamp nullable (soft delete)
  • Index sur les FK et champs fréquemment recherchés
  • Relations définies explicitement

3. Fichiers Générés

  1. Schema/Migration : Dans le dossier de l'ORM
  2. Entity type dans core/entities/{entity}.ts :
    • Type TypeScript pur (pas d'import ORM)
    • Validation via Zod schema
  3. Port dans core/ports/i-{entity}-repo.ts :
    • Interface du repository avec CRUD de base
  4. Adapter dans adapters/db/{entity}-repo.ts :
    • Implémentation du port avec l'ORM choisi
    • Inclut soft delete, pagination, filtres de base

4. Validation

  • Générer et exécuter la migration
  • tsc --noEmit
  • Mettre à jour .claude/memory/domains.md

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
