multi-plane-packages

multi-plane-packages is a cursor rule for Cursor from prisma/orm. It costs 0 tokens per session (901 once invoked), scanned A, original, Apache-2.0.

A directory and configuration pattern for packages that contain shared code plus separate migration and runtime code.

In plain words
What is it for?
Use it when a package provides both command-line or migration entry points and runtime implementations, with separate exports for each.
Why use it?
It makes boundaries between code used for database changes, running applications, and shared logic clear.

About the project

Prisma ORM is a Node.js and TypeScript database toolkit that lets applications work with databases through a programming interface instead of writing every query directly in SQL. Developers use it with databases including PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, MongoDB, and CockroachDB. The catalogue add-ons provide agent rules, skills, hooks, agents, and other workflows for using Prisma.

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

multi-plane-packages 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 1mo 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.

Multi-Plane Packages

Overview

Some packages need to span multiple planes (shared, migration, runtime) to provide both CLI entry points and runtime implementations. These packages use a structured directory layout to separate code by plane.

Structure

Multi-plane packages use the following structure:

packages/{domain}/{package-name}/
├── src/
│   ├── core/              # Shared plane code
│   │   ├── adapter.ts    # Core implementation
│   │   ├── codecs.ts      # Codec definitions
│   │   └── types.ts       # Type definitions
│   └── exports/           # Entry points
│       ├── control.ts     # Migration plane (control plane descriptors)
│       ├── runtime.ts     # Runtime plane (runtime factories)
│       ├── adapter.ts     # Re-export from core
│       ├── codec-types.ts # Re-export from core
│       └── types.ts       # Re-export from core

Architecture Config

Multi-plane packages require multiple globs in architecture.config.json, one for each plane:

{
  "glob": "packages/targets/postgres-adapter/src/core/**",
  "domain": "targets",
  "layer": "adapters",
  "plane": "shared"
},
{
  "glob": "packages/targets/postgres-adapter/src/exports/control.ts",
  "domain": "targets",
  "layer": "adapters",
  "plane": "migration"
},
{
  "glob": "packages/targets/postgres-adapter/src/exports/runtime.ts",
  "domain": "targets",
  "layer": "adapters",
  "plane": "runtime"
}

Plane Separation

  • src/core/**: Shared plane code that can be imported by both migration and runtime planes

    • Core implementation (e.g., adapter, codecs, types)
    • No CLI-specific or runtime-specific dependencies
    • Can import from shared plane packages only
  • src/exports/control.ts: Migration plane entry point (control plane)

    • Exports control plane descriptors (ControlAdapterDescriptor, ControlTargetDescriptor, ControlDriverDescriptor, etc.)
    • Can import from migration plane packages (e.g., @internal/cli, @internal/core-control-plane)
    • Can import from core (../core/...)
    • Naming convention: Use control.ts (not cli.ts) and export as ./control (not ./cli)

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.

multi-plane-packages is a cursor rule published in the GitHub repository prisma/orm (47,693 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 901 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
