🛠️ Refactor suggestion

Option name forNames looks suspicious

Up-stream docs use forFieldNames; the short form forNames is not mentioned.
If this key is wrong, the entire require-field-index rule will be ignored and the schema violations you are trying to catch (e.g. missing @@index([tenantId])) will slip through.

In the .prismalintrc.json file between lines 28 and 34, the option name
"forNames" used in the "require-field-index" rule is incorrect and should be
changed to "forFieldNames" to match the upstream documentation. Update the key
from "forNames" to "forFieldNames" to ensure the rule is properly recognized and
enforced, preventing schema violations from being missed.

Hard-coding the connection string makes local & CI setup brittle

Replace the literal "fake-url" with an env("DATABASE_URL") reference so developers and CI can supply their own credentials without touching the schema.

- url = "fake-url"
+ url = env("DATABASE_URL")

In example.prisma around lines 6 to 9, the datasource url is hard-coded as
"fake-url", which makes local and CI setups brittle. Replace the literal string
with env("DATABASE_URL") to load the connection string from an environment
variable, allowing developers and CI pipelines to supply their own database
credentials without modifying the schema file.

🛠️ Refactor suggestion

Users model violates multiple lint rules

  1. Model name is plural ⇒ fails model-name-grammatical-number.
  2. tenantId is not the first field ⇒ fails field-order.
  3. tenantId is missing an index ⇒ fails require-field-index.
  4. Required field removeMe is ignored ⇒ fails forbid-required-ignored-field.

+model User {
 id String @id

+ // removeMe was required but ignored. Either make it optional or drop it entirely.
+ // removeMe String? @ignore
+
+ @@index([tenantId])

Renaming the model will require cascading changes in your codebase & migrations, but it brings the schema in line with the configured rules.

In example.prisma around lines 11 to 18, the Users model violates lint rules:
rename the model to singular form (User), move tenantId to be the first field,
add an index on tenantId, and either remove the required field removeMe or make
it optional if it must be ignored. These changes align the schema with lint
rules but will require updates in your codebase and migrations.

🛠️ Refactor suggestion

UserRole lacks a relation and required index

userId is clearly intended to reference User, yet no @relation is declared and no index is present.
This will also violate the require-field-index rule (forAllRelations: true).

 model UserRole {
 id String @id
- userId String @map(name: "userid")
- // No mapping.
+ userId String @map(name: "userid")
+ user User @relation(fields: [userId], references: [id])
+
+ @@index([userId])

🤖 Prompt for AI Agents 
In example.prisma around lines 31 to 35, the UserRole model's userId field lacks
a @relation attribute linking it to the User model and does not have an index,
which is required for foreign key fields. Add a proper @relation directive to
userId referencing the User model and create an index on userId to comply with
the require-field-index rule and establish the relationship correctly.
