Prisma Next — Quickstart (Adoption)
Edit your data contract. Prisma handles the rest.
This skill takes the user from zero (or near-zero) to a first working query against Prisma Next. Three paths — and they all converge on the same first arc: connect → write → read. Schema editing comes after the first arc, not before.
First-touch orientation — the user has arrived at a Prisma Next project for the first time (a scaffold tool like npx createprisma dropped them in, they cloned a teammate's repo, or they ran prisma-next init themselves and now want to make their first move) and they're asking "what can I do with Prisma Next?", "where do I start?", or "what's next?". The goal is to anchor them on the contract, get them connected to a database, round-trip one row, and let further commands surface organically.
Greenfield — new project, fresh database. User runs prisma-next init themselves. init seeds a starter contract with a sample model, so the path joins the first-touch orientation arc as soon as the database is initialised.
Brownfield-DB — existing database, no contract yet. Infer the contract from the database with contract infer, sign the marker with db sign, then write queries against one of the existing tables.
This skill does not cover migrating from another ORM (Drizzle, Prisma 6/7, Sequelize, TypeORM, Kysely, Knex, raw drivers). Those are separately-installable skills.
When to Use
User asks "what can I do with Prisma Next?", "what can I do next with Prisma?", "where do I start?", "what should I do first?" — and a PN project already exists on disk. First-touch orientation path below.
User just ran createprisma (or equivalent scaffold tool) and is asking what to do next. First-touch orientation path.
User is starting a new project and wants to use Prisma Next. Greenfield path.
User has an existing database (no PN contract) and wants to introduce PN. Brownfield-DB path.
User typed "prisma-next init", "get started with PN", "set up PN", "how do I scaffold a project". Greenfield path.
User says "I have an existing Postgres/Mongo, how do I start using PN?". Brownfield-DB path.
When Not to Use
User already has a PN project and wants to add a model → prisma-next-contract.
User wants to migrate FROM a specific ORM → install @prisma-next/migrate-from-<orm>-skill (separate).
User wants to wire db.ts in a project that already has a contract → prisma-next-runtime.
User wants to integrate Prisma Next with a build tool (Vite plugin, Next.js, …) → prisma-next-build.
Key Concepts
Contract: the data model. Authored as contract.prisma (PSL, the canonical surface) or contract.ts (TypeScript builder). The framework reads it and emits two artefacts: contract.json (runtime IR) and contract.d.ts (types).
Target: the backing store. Today: postgres or mongodb. Picked at init time; baked into the @prisma-next/<target> façade the scaffold imports from.
Authoring mode: how you write the contract. psl (Prisma Schema Language, default) or typescript (programmatic builder, optionally paired with the Vite plugin for auto-emit during vite dev — see prisma-next-build).
Façade packages. The scaffold installs exactly one façade per target — @prisma-next/postgres (or @prisma-next/mongo). User code imports from façade subpaths (@prisma-next/postgres/config, @prisma-next/postgres/runtime, @prisma-next/postgres/contract-builder). The façade bakes in the family / target / adapter / driver wiring; never reach past it. See prisma-next-contract for the full list.
db.ts: the runtime entry point. Lives next to the contract source at src/prisma/db.ts. Imports the contract artefacts and exports a db value the rest of the app uses.
Marker: a pn_meta_marker row in your database that records the contract hash. Lets PN detect drift between contract and live DB. Created by db init (greenfield / first-touch orientation) or db sign (brownfield).
Canonical on-disk layout
Every application that consumes Prisma Next uses the same shape:
<app-root>/
├── prisma-next.config.ts ← project config at repo root
├── src/
│ └── prisma/
│ ├── contract.prisma ← (or contract.ts) — schema source you author
│ ├── contract.json ← emitted by `contract emit` — do not edit
│ ├── contract.d.ts ← emitted by `contract emit` — do not edit
│ └── db.ts ← runtime entry; the rest of `src/` imports from here
└── migrations/
└── app/ ← created on first `migration plan` / `db init`
├── refs/head.json
└── <timestamp>_<slug>/
├── migration.json
├── ops.json
├── end-contract.json
├── end-contract.d.ts
└── migration.ts
Three things to internalise:
src/prisma/ is the home for the contract — source + emitted artefacts + db.ts all colocated. The rest of src/ imports from ./prisma/db (or ../prisma/db, depending on file depth).
migrations/app/ — the app/ segment is the consuming application's space-id. Extensions you depend on get sibling directories under migrations/ (one per extension contract-space), but you don't write into those — only the app/ subtree is your migrations.
prisma-next.config.ts lives at the repo root, not under src/. Every command resolves paths relative to the config's directory.
Contributors building extension packages or aggregate-root monorepo packages use a different layout — src/contract.{prisma,ts} (no prisma/ subdir) + migrations/<timestamp>_<slug>/ (no app/ segment). That distinction is intentional; see prisma-next-contract for which path applies to you.
Heads up — prisma-next init currently scaffolds the wrong layout. It writes prisma/contract.{prisma,ts} and prisma/db.ts at the repo root instead of under src/prisma/. Tracked as TML-2532. Until the fix lands, either pass --schema-path src/prisma/contract.prisma to init, or move the scaffolded prisma/ directory into src/prisma/ after init and update the contract path in prisma-next.config.ts to match. The canonical layout above is what the demo example uses and what the rest of the framework expects.
Your first arc — connect, write, read
All three paths in this skill converge here. Once the project is scaffolded and the database is reachable, the first move is always the same: connect, write a row, read it back, against whatever model the contract already declares. Don't touch the contract source on this first move — extend it later, after the round-trip works.
Write the snippet in a fresh file directly under src/ (e.g. src/first-arc.ts) so the relative import resolves to one level deep:
// src/first-arc.tsimport'dotenv/config';
import { db } from'./prisma/db';
// Write a row against the starter model. Adapt the field names to whatever// model your contract source actually declares — read it first.await db.orm.User.create({ email: 'alice@example.com' });
// Read it back.const users = await db.orm.User.select('id', 'email').all();
console.log(users);
If that prints [{ id: 1, email: 'alice@example.com' }], the project is wired end-to-end and the user has crossed from "I have a project" to "I'm building."
db.orm.<Model> is the default ORM lane — model-shaped, fully typed against the contract, lazily connects to the database on first use (it picks up DATABASE_URL from .env via the runtime's dotenv/config-loaded environment). The deeper prisma-next-queries skill covers the rest of the surface (filters, joins, transactions, the SQL builder, raw SQL, TypedSQL) when the user is ready.
Mongo target: the snippet above is SQL-target shape. On @prisma-next/mongo, db.orm is keyed by the collection's storage name (@@map(...), or the lowercased model name if no @@map), so the same arc reads await db.orm.users.create(...) / await db.orm.users.select('id', 'email').all() — not db.orm.User. Full rule and rewrite recipe in prisma-next-queries § MongoDB ORM addressing.
Prerequisites for the arc to work. All three paths leave these in place by the time you reach the arc:
prisma-next.config.ts exists at the repo root and declares the target + contract source (typically src/prisma/contract.prisma or src/prisma/contract.ts).
The contract source exists at src/prisma/contract.{prisma,ts} (a starter model from init, or the inferred contract from contract infer, or whatever the bootstrap tool generated).
src/prisma/db.ts exists and instantiates the runtime with the emitted contract.
DATABASE_URL is set in .env (or wherever the runtime's config tells it to look).
The database has been initialised (db init) or marker-signed (db sign), so the marker row exists and the schema matches the contract.
The three workflows below each describe how their path gets the user to that state. After that, the arc above is the same.
Workflow — First-touch orientation
Triggers: "what can I do with Prisma Next?", "what can I do next with Prisma?", "where do I start?", "I just ran createprisma", "what's next?", or any close variant — paired with a PN project already on disk (scaffolded by createprisma, by prisma-next init, by a teammate, however).
The user's high-level intent is "I want to be running an application against my database, against this thing called Prisma Next." The job of this workflow is to anchor them on the contract, get one round-trip working, and let further commands surface organically as their next move requires them. It is orientation, not a tour, not a feature inventory, not a syllabus.
Concept — what to communicate first
Prisma Next is contract-first. Everything the framework does — query types, migrations, runtime types, drift detection — flows from a single source of truth: the contract. The contract describes the user's application's data model. The framework reads it; the framework derives the rest. Lead with this.
The first response to "what can I do with Prisma Next?" names the contract path, frames its role in one sentence, and then steers toward getting the user's application running. Don't open with a feature inventory. Don't open with a list of commands. Open with: "Your contract is at <path>. It describes your application — your query types, migrations, and runtime types all flow from it. Let's get you connected to a database so your app can actually run against it."
The first arc — once oriented — is connect → write → read. Not edit-the-contract-first, not plan-a-migration-first. The user's win is I have application code running against my database.
Step 1 — Read the project, name the contract
Before saying anything specific to the user, read:
prisma-next.config.ts at the repo root — what target (postgres / mongodb) is wired, what contract: path it declares, what extensions are installed.
The contract source the config declares (canonically src/prisma/contract.prisma or src/prisma/contract.ts; a project that pre-dates TML-2532 may have it at prisma/contract.{prisma,ts} instead — check the contract field of the config) — what starter models, if any, exist.
src/prisma/db.ts (next to the contract) — the runtime entry point.
.env / .env.example — is DATABASE_URL set, or only the example?
Optionally pnpm prisma-next db verify — does the live DB match the contract?
Then say the contract path back to the user, with its role attached. Something like: "Your contract is at src/prisma/contract.prisma, and it currently declares a User model. The contract describes your app — every query type, migration, and runtime type the framework gives you flows from this file. Let's get your app connected to a database next." The exact wording is up to the agent; what matters is that the user leaves the first response knowing where the contract is and that it is the source of truth.
Step 2 — Get the user's app connected and round-tripping
The motivation is "so your app can actually run against your database", not "so the prerequisite checklist passes". The mechanics depend on what's already in place from Step 1:
Everything already wired. Go straight to writing and reading a row (see Your first arc — connect, write, read above). Adapt the snippet to whatever model the contract declares.
DATABASE_URL not set. Have the user set it in .env (not in prisma-next.config.ts — see Pitfall 5). Then pnpm prisma-next db init to apply the current contract to that database and write the marker row. Now the app can connect.
Database is connectable but not yet aware of the contract (marker row missing; db verify reports drift). Run pnpm prisma-next db init. (db update is the alternative for quick dev cycles — it's looser, doesn't write a migration history, and is what users reach for when they want to iterate on the schema fast. Mention it if the user asks how to make schema changes flow to the DB; don't pre-explain it.)
Contract is empty (bootstrap left the source blank). Add one model with two fields (e.g. User { id, email }), pnpm prisma-next contract emit, then pnpm prisma-next db init. Minimal — get the round-trip working, then extend.
The user encounters db init (and optionally db update, contract emit) here because they're the commands their current move requires. They learn what those commands are by using them.
Step 3 — Round-trip a row
Run the snippet from Your first arc — connect, write, read above against whatever model the contract declares. When it prints the row back, the user has crossed from "I have a project" to "my app runs against my database". That's the win.
Step 4 — Hand off to the next move
Now ask the user what they want to build. Route to the skill that owns that move:
More queries (filters, joins, transactions, raw SQL, TypedSQL) → prisma-next-queries.
Add a model, change a field, add a relation → prisma-next-contract. They'll touch contract emit and db update (or migration plan + migrate) as part of that workflow.
Vite / Next.js / dev-server integration → prisma-next-build.
They want a fuller toolbelt overview at this point — Commands you'll use day-to-day below is the one-glance summary.
Anti-patterns on this path
Leading with a feature tour or capability inventory. The user asked what they can do. Get them doing it.
Listing commands before any have been used. Commands belong to specific moves; surface them when the move requires them.
Diving into migration concepts before one query has run. Migrations exist; their value lands later.
Adding several models in one go. Add one, get one query green, then iterate.
Walking the user through prisma-next.config.ts keys. The scaffold's defaults are correct; revisit when the user needs to change something.
Skipping the contract framing. Even one line — "your contract is at <path>, it's the source of truth" — anchors the user; without it, the rest of the workflow lands as disconnected ceremony.
Workflow — Greenfield
The concept: prisma-next init is one CLI command that scaffolds config, schema, runtime, dependencies, and the contract emit step. It operates on the current working directory — there is no positional project-name argument. Make the directory, cd in, then run init.
mkdir my-app && cd my-app
pnpm init # if no package.json yet
pnpm dlx prisma-next init # interactive# or non-interactive (CI / agent runs):
pnpm dlx prisma-next init --yes --target postgres --authoring psl
Telemetry is opt-out. The CLI collects anonymous usage data by default. Every command — including init — prints a one-time notice to stderr on first use, then sends; there is no interactive consent prompt. Opt out anytime by running prisma-next telemetry disable, with DO_NOT_TRACK=1 or PRISMA_NEXT_DISABLE_TELEMETRY=1, or by setting "enableTelemetry": false in your user config (prisma-next config dir, notprisma-next.config.ts). Run prisma-next telemetry status to see what's currently in effect. This is relevant for agent-driven runs — the CLI records that an agent invoked it. What's collected, the per-user config path, and how to fully reset are documented in docs/Telemetry.md.
The flags init accepts (run prisma-next init --help for the source of truth):
--target <db> — postgres or mongodb.
--authoring <style> — psl or typescript.
--schema-path <path> — defaults to prisma/contract.prisma (or prisma/contract.ts). Pass --schema-path src/prisma/contract.prisma (or .../contract.ts) to scaffold into the canonical src/prisma/ location directly — init's default is wrong today, see TML-2532.
--force — overwrite an existing scaffold without prompting (re-running init in a scaffolded directory triggers the reinit flow — --force skips the confirmation).
--write-env — also write .env (default writes only .env.example; .env stays under your control).
--probe-db — connect to DATABASE_URL once and check the server version against the target's minimum.
--strict-probe — fail init if the probe fails (no-op without --probe-db).
--no-skill — skip Prisma Next skills installation (air-gapped / restricted environments). The skill cluster is always installed at the project level — never globally — so its version stays locked to the project's Prisma Next version.
init writes (when it runs cleanly):
prisma-next.config.ts at the project root.
The contract source at --schema-path — src/prisma/contract.prisma if you passed the canonical override, prisma/contract.prisma if you accepted the (currently-wrong) default.
db.ts in the same directory as the contract source.
prisma-next.md — a human quick-reference.
.env.example (and .env if --write-env).
Updates package.json (deps + scripts) and tsconfig.json (required compiler options).
Installs deps and runs prisma-next contract emit once.
Registers Prisma Next skills with the local agent runtime.
If you took init's default and ended up with a top-level prisma/ directory (TML-2532), the cleanup is one move + one config edit:
mkdir -p src && mv prisma src/prisma
# Then update prisma-next.config.ts so `contract` reads# 'src/prisma/contract.prisma' (or .ts) instead of 'prisma/contract.prisma'.
pnpm prisma-next contract emit # re-emits contract.json + contract.d.ts under src/prisma/
Do this before running db init — once the marker row is written, restructuring is harder.
After init succeeds, the path converges on Your first arc — connect, write, read above. init has already seeded a starter contract with User and Post models (with a relation between them) and run contract emit once; the only remaining prerequisites are setting DATABASE_URL and initialising the database. Two commands:
Set DATABASE_URL in .env (copy from .env.example).
Initialise the database: pnpm prisma-next db init. Creates tables, indexes, constraints, and writes the marker row — using the starter contract init generated.
Then run the snippet from Your first arc above against the User model. When the user is ready to extend the contract — add more models, change fields, add relations — chain to prisma-next-contract. For more queries, chain to prisma-next-queries.
Why this is queries-first, not schema-editing-first.init ships with User and Post on purpose: the user shouldn't have to design a schema to prove their setup works. Extending the contract is the next move after the first arc lands, not part of getting there. If the user asks you to skip straight to "add a Comment model" — sure, do that — but get one query green against User or Post first if there's any doubt the project is wired correctly.
Workflow — Brownfield-DB (existing database, no contract)
The concept: against an existing database with no PN contract, contract infer walks the live schema (tables, columns, indexes, constraints) and writes a PSL contract that describes it. The result is a starting point, not the final contract — review and clean it up, then db sign to record the current contract hash as the marker (instead of letting db init try to recreate the schema from scratch).
(Note: the flag is --output, not --out. Run prisma-next contract infer --help for the full surface.)
The agent should pause here and read the inferred PSL. Symptoms a re-author pass is needed:
Tables PN couldn't categorise (e.g. legacy linking tables you could express as relations).
Columns where PN's type guess is wrong (e.g. String where you want an extension type like pgvector.Vector(length: 1536)).
Missing @unique / @index hints PN couldn't see.
Field names you'd prefer to alias.
Then re-emit and sign:
pnpm prisma-next contract emit
pnpm prisma-next db sign
pnpm prisma-next db verify # confirms the DB matches the contract; reports drift if not
Then run the snippet from Your first arc — connect, write, read above, using one of your existing tables in place of the starter model. The arc is the same; only the path that got you there differs.
Commands you'll use day-to-day
A reference table — not a script to recite at the user. Commands surface in the workflow above as the user's next move requires them; this table is here for the moment the user asks for a wider view (typically after the first round-trip), and as a one-glance summary anyone newly oriented to Prisma Next can scan. For flag-level detail, run <command> --help; the help output is the source of truth.

Decision — PSL vs TypeScript authoring
PSL (contract.prisma) — the default. Concise, declarative, familiar to anyone who has used Prisma. Recommended for most projects.
TypeScript (contract.ts) — a programmatic builder. Use when the contract is genuinely computed (multi-tenant per-tenant variants), when you reuse contract fragments across files, or when an extension requires constructs PSL doesn't yet express (e.g. pgvector's parameterised storage-type registration). Pairs with the Vite plugin from prisma-next-build for auto-emit on save.
Switch authoring later by re-running prisma-next init in the same directory. The init flow detects the existing scaffold and prompts to reinit (use --force to skip the prompt in non-interactive runs). Existing contract content is not automatically translated — you'll re-author by hand in the target language.
Common Pitfalls
Running prisma-next init <project-name> with a positional argument.init operates on the current working directory; there is no positional project-name argument. mkdir foo && cd foo && pnpm dlx prisma-next init.
init doesn't connect to your database. It only scaffolds files and installs dependencies (and runs the initial contract emit). You connect with db init / db update / migrate. If init succeeds and queries fail, the issue is DATABASE_URL, not init.
Treating inferred PSL as the final contract.contract infer produces a starting point. Don't db sign against a contract you haven't read.
Forgetting to emit after editing the contract. The contract artefacts (contract.json, contract.d.ts) are stale until you run contract emit. If the type-checker says a model "doesn't exist", you skipped emit.
Setting DATABASE_URL in prisma-next.config.ts instead of .env. The config reads .env automatically via dotenv/config. Hardcoding the URL leaks credentials and bypasses per-environment overrides. See prisma-next-runtime.
Hand-editing contract.json or contract.d.ts. They're emitted artefacts; the next contract emit overwrites your changes. Edit the source instead.
Using --out for contract infer. The flag is --output.
What Prisma Next doesn't do yet
Migration from another ORM. Prisma Next doesn't migrate your schema from Drizzle / Prisma 6/7 / Sequelize / TypeORM / Kysely / Knex / a raw driver. Workaround: install the matching @prisma-next/migrate-from-<orm>-skill if one exists for your source, or treat the source as a brownfield database and contract infer from it. If you need a guided migration flow built-in, file a feature request via the prisma-next-feedback skill.
prisma db push-style production sync.db update is the quick development path; for production, use migrations (migration plan + migrate). PN deliberately does not offer a "push-to-prod-without-a-migration" surface — see prisma-next-migrations.
Studio / GUI database browser. Use prisma-next db schema for a CLI tree-style summary of the live DB. If you need an interactive UI, file a feature request via the prisma-next-feedback skill.
Reference Files
This skill is intentionally body-only; prisma-next init --help, contract infer --help, and db sign --help are the authoritative surfaces for flag-level detail. When in doubt, run --help and read the actual command's description rather than guessing from this skill.
Checklist
Confirmed which path applies (first-touch orientation / greenfield / brownfield) before proposing commands.
First-touch orientation: named the contract path back to the user and framed its role (source of truth from which query types, migrations, and runtime types flow) before proposing any commands.
All paths: brought the project to the Your first arc prerequisites (config, contract source, db.ts, DATABASE_URL, marker row) before writing application code.
All paths: ran the first arc — one create + one select against the starter (or inferred) model — and got the round-trip working green.
All paths: did not edit the contract source as part of the first arc. Schema extension is the next move, not the first.
All paths: did not lead with a feature tour, capability inventory, or recital of CLI commands. Commands surfaced as the user's current move required them.
Confirmed the user's target (postgres / mongodb) and authoring mode (psl / typescript).
First-touch orientation: read prisma-next.config.ts, the contract source, db.ts, and .env before proposing anything — didn't assume what the scaffold tool / teammate left in place.
Greenfield path: ran prisma-next init from the project directory — no positional project-name argument.
All paths: the project ended up in the canonical src/prisma/contract.{prisma,ts} + src/prisma/db.ts + migrations/app/ layout — including moving the scaffolded directory out of a top-level prisma/ if init produced one (TML-2532).
Brownfield path: ran contract infer --db "$DATABASE_URL" --output src/prisma/contract.prisma, reviewed the result, then contract emit + db sign.
Set DATABASE_URL in .env and confirmed the value is reachable.
Initialised the DB (db init greenfield / first-touch orientation) or signed the marker (db sign brownfield).
Did NOT hand-edit contract.json or contract.d.ts.
Did NOT set DATABASE_URL in prisma-next.config.ts.
Confirmed the user understands what the next skill is for their workflow (typically prisma-next-queries for more queries, then prisma-next-contract when they're ready to extend the schema).
