612-637: 🛠️ Refactor suggestion | 🟠 MajorMissing functional tests for
makeModelCreateSchemaandmakeModelUpdateSchema.The new
makeModelCreateSchemaandmakeModelUpdateSchemamethods are only tested for@metadescription propagation. There are no tests verifying their core behavior:
- Create schema: fields with
@defaultshould be optional; relation fields should be excluded; required fields without defaults should remain required.- Update schema: all non-relation fields should be optional; relation fields should be excluded.
These are critical behavioral contracts that should have test coverage.

67-90:makeModelCreateSchemare-applies.optional()on top of cardinality already applied bymakeScalarFieldSchema.For optional fields,
makeScalarFieldSchema→applyCardinalityalready wraps with.nullable().optional(). Then line 79-80 adds another.optional(), resulting in.nullable().optional().optional(). The behavior is correct at runtime (extra.optional()is a no-op), but it adds unnecessary nesting to the schema chain.Consider extracting a
makeBaseFieldSchema(without cardinality) to use in create/update methods, letting them apply cardinality themselves.🤖 Prompt for AI Agents

51-58: Potential doubleZodOptionalwrapping for optional fields with defaults inGetModelCreateFieldsShape.When a field is both
optional(viaModelFieldIsOptional) and has a default (FieldHasDefault), this producesZodOptional<ZodOptional<ZodNullable<T>>>. The innerZodOptionalAndNullableIfaddsZodOptional<ZodNullable<T>>, thenZodOptionalIfwraps it in anotherZodOptional. While functionally equivalent at runtime, this results in a less precise inferred type. The same pattern applies toGetModelUpdateFieldsShape(lines 60-66).This is a type-level concern only and unlikely to cause real issues, but worth noting for type hygiene.

addStringValidationand line 448 inevalCall) construct aRegExpfrom a pattern string originating from ZModel schema attributes. While these patterns come from the schema author (not end-user input), a malicious or accidentally catastrophic regex could cause excessive backtracking.If schema authors are trusted, this is low risk.

In `@packages/zod/src/types.ts`:
- Line 42: The code uses internal Zod marker types z.core.$strict and
z.core.$loose (seen in types.ts around the occurrences at lines referenced and
in factory.ts usages); replace those internal markers with stable, public APIs:
use z.strictObject(...) or z.looseObject(...), or call .strict() / .loose() on
the relevant z.object(...) schemas, and update any type parameter references in
functions or type aliases (e.g., the symbols currently referencing
z.core.$strict / z.core.$loose in types.ts and factory.ts) to the corresponding
public schema types so the public API no longer depends on internal z.core
markers.
In `@packages/zod/src/utils.ts`:
- Around line 348-385: The switch in evalBinary currently lacks a default branch
so unknown operators silently return undefined; add a default: throw new
Error(...) to the switch inside evalBinary (the function handling expr.op) so it
throws a clear error for unsupported/unknown binary operators, include the
operator value in the thrown message to aid debugging.
- Around line 415-439: The code uses getArgValue<string>(expr.args?.[1])! to
obtain the search term which can be undefined for non-literal args; remove the
non-null assertion and after retrieving search (and caseInsensitive) add an
invariant that ensures search is a string (e.g., invariant(typeof search ===
'string', `"${f}" search argument must be a string literal`)) and similarly
validate the resolved caseInsensitive is boolean if present; update the block
around getArgValue, search, and applyStringOp (referencing getArgValue,
expr.args?.[1], search, caseInsensitive, and applyStringOp) to fail fast with a
clear error when non-literal or wrong-type args are passed.

- Around line 65-70: The `@regex` branch in utils.ts (case '@regex' where result =
result.regex(new RegExp(pattern))) and the similar use in evalCall must not
construct arbitrary RegExp instances directly because catastrophic backtracking
can cause ReDoS; validate or sanitize the pattern at schema-build time (e.g.,
using a safe-regex check or a safer engine like re2) and reject or throw a
descriptive error for unsafe/complex patterns, or document and enforce a
whitelist/limit on pattern features before calling new RegExp; apply the same
validation/guard to the pattern handling in evalCall so both call sites refuse
or transform unsafe patterns instead of directly instantiating RegExp.

In `@packages/zod/src/utils.ts`:
- Around line 424-427: The non-null assertion on the getArgValue call hides
runtime undefineds; replace the `const search =
getArgValue<string>(expr.args?.[1])!` with a safe check: assign the result to a
variable (e.g., `const search = getArgValue<string>(expr.args?.[1])`) and then
assert/throw if it's undefined (use `invariant(search, \`"... ${f}" requires a
literal search string\`)` or similar) before any use (such as
`search.toLowerCase()`); also ensure the boolean caseInsensitive uses its parsed
value only after validating `search`. This change touches the getArgValue usage
and the surrounding invariant logic so the code never calls string methods on
undefined.
- Around line 448-449: Remove the non-null assertion after the getArgValue call
so that pattern is typed as possibly undefined (i.e., change const pattern =
getArgValue<string>(expr.args?.[1])! to without the '!'), and keep the runtime
guard invariant(pattern !== undefined, `"${f}" requires a pattern argument`);
this ensures the compile-time type matches the actual runtime check for
getArgValue, consistent with the same fix applied earlier around line 426.
