presets.dev: Instructions file for GitHub Copilot

release/prisma/native/copilot/.github/instructions/prisma.instructions.md

presets.dev prisma.instructions.md is an instructions file for GitHub Copilot from beel-collab/presets.dev. It costs 1,175 tokens per session, scanned A, original, MIT.

Prisma development instructions are rules for using Prisma, a tool that maps application code to database tables and generates database queries. They cover schema changes, migrations, generated clients, PostgreSQL connections, and query shape.

In plain words
What is it for?
They guide agents when changing Prisma schemas, migrations, database clients, PostgreSQL access, relations, transactions, and queries.
Why use it?
They help avoid incompatible dependency upgrades, unsafe migrations, incorrect database connections, and inefficient or incomplete queries.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is beel-collab/presets.dev's own configuration. It tells GitHub Copilot how to work on presets.dev itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything presets.dev configures →

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

presets.dev prisma.instructions.md 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 today.

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.

Prisma Copilot Instructions: Schema, Migrations and Query Shape

Path-specific Copilot instructions for Prisma. They apply through applyTo and leave .github/copilot-instructions.md in place.

Updated for Prisma 7.10.1 stable, Nov 2026

Do not upgrade dependencies or the framework version unless the task asks.

The npm latest tag for prisma is an 8.0 release candidate. The prev tag, 7.10.1, is the stable line. Stay on the major the repository installs. Do not bump a project to Prisma 8 because latest resolved to the RC. Postgres stays on the major the project runs. Do not assume a newer Postgres major is what this app uses.

ORM 7 shape

On Prisma 7 the CLI reads prisma.config.ts. defineConfig from prisma/config points datasource.url at the direct database URL used for migrations. The schema file no longer owns that URL.

The client is created with a driver adapter. For Postgres on Node, that is PrismaPg from @prisma/adapter-pg and new PrismaClient({ adapter }). Do not pass a prisma:// or hosted prisma+postgres:// Accelerate URL to PrismaPg. Those strings are not TCP connection strings.

The generator is prisma-client with a required output directory. Import PrismaClient from that generated path. The v7 upgrade example uses ./generated/prisma/client, not @prisma/client. Do not hand-edit the generated files.

Hosted Accelerate URLs, including prisma+postgres://accelerate.prisma-data.net, retire on 1 December 2026. Local prisma+postgres://localhost URLs are not that retirement. Move CLI config to a direct URL before that date. If the app still uses the Accelerate extension, keep that temporary and do not mix it with a driver adapter on the same URL.

Project shape

schema.prisma is the model. Migrations in prisma/migrations are the history. Do not edit a migration that has already shipped. Add a new one.

The shadow database is a disposable database. Never point shadowDatabaseUrl at production. A migrate command against production is something a person runs on purpose. Do not run migrate dev or migrate reset against a shared database.

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.
