best-practices

best-practices is a cursor rule for coding agents from ofershap/drizzle-best-practices. It costs 114 tokens per session, scanned A, original, MIT.

Rules for writing database code with Drizzle ORM, a TypeScript library for querying databases. They cover schema definitions, type inference, queries, and migrations.

In plain words
What is it for?
Use them when defining Drizzle schemas, inferring database types, building queries, creating migrations, or adding prepared statements for frequent queries.
Why use it?
They keep database code consistent with Drizzle's approach and discourage manual types, handwritten migration SQL, and unnecessary raw queries.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

best-practices 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 3d 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

  • Use Drizzle schema definition (pgTable/mysqlTable/sqliteTable) - never write Prisma-style schema files
  • Use $inferSelect and $inferInsert for type inference - never manually define types that mirror DB schemas
  • Use the Drizzle query builder API - never use raw SQL strings unless absolutely necessary
  • Use drizzle-kit for migrations - never write migration SQL manually
  • Use prepared statements for queries that run frequently
Changes

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.
