postgres-drizzle

postgres-drizzle is a skill for Claude Code, Codex from jkomyno/.dotfiles. It costs 34 tokens per session (653 once invoked), scanned A, a copy of postgres-drizzle, MIT.

A set of patterns for building applications with PostgreSQL, a relational database, and Drizzle ORM, a TypeScript library for defining and querying database tables.

In plain words
What is it for?
It helps model table relationships, write queries, create and apply migrations, use transactions and connection pooling, work with JSONB data, add indexes, and configure row-level security.
Why use it?
It helps avoid common database design and performance problems, such as missing indexes, inefficient repeated queries, unsafe schema changes, and poor connection handling.

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

postgres-drizzle 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 25d 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.

How it starts

The opening of the file, as written. The whole thing — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PostgreSQL and Drizzle ORM

Match database work to the project's installed API and deployment context. The user's explicit instructions take precedence over this skill's guidelines.

Establish the database contract

Use the relevant schema/query, migration history, and requested behavior as input. For Drizzle code, inspect installed drizzle-orm/drizzle-kit versions and the driver; for SQL, establish the PostgreSQL version when a version-specific feature matters.

The references cover PostgreSQL 17/18 and distinguish Drizzle's 0.x relations() API from the v1 defineRelations() API. Do not mix them or infer the installed API from an npm dist-tag. When the version is unknown, use imports/lockfiles or ask for the missing version before giving version-dependent code.

Keep changes consistent

  • Declare database foreign keys separately from ORM relation metadata. Match nullability, uniqueness, and delete behavior to the actual relationship.
  • Use the transaction handle for every statement in that transaction; a query through the outer connection can escape it.
  • Diagnose slow queries from plans and workload evidence. Evaluate indexes on referencing columns; PostgreSQL does not create them automatically.
  • Generate and inspect migration SQL for schema changes. Preserve applied migration history; use a new migration for subsequent changes.
  • Establish the target before applying migrations or push. Authoring or reviewing SQL does not itself require executing it against a database. Continue execution when the user has already authorized that target and action.
  • Treat EXPLAIN ANALYZE as query execution, including writes. Use a suitable test target or non-executing plan when execution is outside the task.

Deliver the requested SQL/code, migration, or diagnosis, with compatibility assumptions and relevant verification. If execution is requested but the target is missing, prepare the change and ask only for that missing target.

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.
