Error utility & barrel exports
packages/shared/src/errors/globalHookError.ts, packages/shared/src/error.ts
Add createClerkGlobalHookError(error: ClerkError) that attaches isClerkApiResponseError and isClerkRuntimeError predicates to the error; re-export ClerkError and createClerkGlobalHookError from the package barrel.
Shared types update
packages/shared/src/types/state.ts
Import ClerkGlobalHookError and change Errors.global from `unknown[]
Event payload typing

State integration
packages/clerk-js/src/core/state.ts
Type onResourceError payload error as `ClerkError
ClerkAPIError constructor refactor
packages/shared/src/errors/clerkApiError.ts
Simplify constructor by building an inline parsedError object and assigning properties directly rather than using a separate parseJsonError helper.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • Focus review on:
    • packages/clerk-js/src/core/signals.ts: correctness of hasFieldErrors branch and population of raw/fields/global.
    • packages/shared/src/errors/globalHookError.ts: correct predicate attachment and typings returned.
    • Cross-package typing consistency where unknownClerkError | null was applied.
    • packages/shared/src/errors/clerkApiError.ts: ensure refactor preserves previous parsing semantics.

Poem

🐇 I tuck a tag on an error's sleeve,
Two tiny predicates snugly weave.
Fields sorted neat, globals wrapped tight,
I hop through types in the moonlit night. ✨

⚠️ Potential issue | 🟠 Major

Clarify predicate binding and avoid mutating the input parameter.

The function mutates the input error object by attaching predicates to it, which violates immutability principles. More critically, the attached predicates (isClerkApiResponseError, isClerkRuntimeError) are likely type guards that expect an error parameter (e.g., (error: unknown) => error is ClerkApiResponseError). Attaching them unbound creates a confusing API where consumers would need to call error.isClerkApiResponseError(error), which is redundant.

If the intent is to provide predicate methods that check the error itself, bind them by wrapping in closures:

 export function createClerkGlobalHookError(error: ClerkError) {
const predicates = {
- isClerkApiResponseError,- isClerkRuntimeError,+ isClerkApiResponseError: () => isClerkApiResponseError(error),+ isClerkRuntimeError: () => isClerkRuntimeError(error),
} as const;
- for (const [name, fn] of Object.entries(predicates)) {- Object.assign(error, { [name]: fn });- }-- return error as ClerkError & typeof predicates;+ return Object.assign({}, error, predicates) as ClerkError & typeof predicates;
}

This eliminates mutation and provides a cleaner API where error.isClerkApiResponseError() checks the error itself.

Based on coding guidelines: "Prefer readonly properties for immutable data structures."

🤖 Prompt for AI Agents
In packages/shared/src/errors/globalHookError.ts around lines 10 to 21, the
current implementation mutates the incoming error by assigning unbound predicate
functions to it; instead, return a new object that preserves the original error
properties (don’t mutate the input) and add readonly predicate methods that are
zero-argument closures which call the original type-guard predicates with the
original error value (e.g., () => isClerkApiResponseError(origError)); ensure
these added properties are non-writable/read-only (use Object.defineProperty or
equivalent) and return the result typed as ClerkError & typeof predicates so
consumers can call error.isClerkApiResponseError() without passing the error and
immutability is preserved.

⚠️ Potential issue | 🟠 Major

Restore the raw API errors array

Errors.raw is documented (packages/shared/src/types/state.ts Line 74) as “The raw, unparsed errors from the Clerk API.” Storing the aggregate ClerkAPIResponseError here drops the per-error payload consumers rely on. Keep raw as the API error list.

Apply this diff to preserve the original payload:

- parsedErrors.raw = [error];+ parsedErrors.raw = [...error.errors];
parsedErrors.global = [createClerkGlobalHookError(error)];
🤖 Prompt for AI Agents
In packages/clerk-js/src/core/signals.ts around lines 88 to 91, parsedErrors.raw
is being set to the aggregate ClerkAPIResponseError object instead of the
original per-error payload; change the assignment to preserve the API error list
by setting parsedErrors.raw to the error.errors array (or an empty array
fallback if needed) so consumers receive the raw, unparsed error entries, while
keeping parsedErrors.global as createClerkGlobalHookError(error).

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • Focus review on:
    • packages/clerk-js/src/core/signals.ts: correctness of hasFieldErrors branch and population of raw/fields/global.
    • packages/shared/src/errors/globalHookError.ts: correct predicate attachment and typings returned.
    • Cross-package typing consistency where unknownClerkError | null was applied.
    • packages/shared/src/errors/clerkApiError.ts: ensure refactor preserves previous parsing semantics.

⚠️ Potential issue | 🟠 Major

Clarify predicate binding and avoid mutating the input parameter.

The function mutates the input error object by attaching predicates to it, which violates immutability principles. More critically, the attached predicates (isClerkApiResponseError, isClerkRuntimeError) are likely type guards that expect an error parameter (e.g., (error: unknown) => error is ClerkApiResponseError). Attaching them unbound creates a confusing API where consumers would need to call error.isClerkApiResponseError(error), which is redundant.

If the intent is to provide predicate methods that check the error itself, bind them by wrapping in closures:

 export function createClerkGlobalHookError(error: ClerkError) {
const predicates = {
- isClerkApiResponseError,- isClerkRuntimeError,+ isClerkApiResponseError: () => isClerkApiResponseError(error),+ isClerkRuntimeError: () => isClerkRuntimeError(error),
} as const;
- for (const [name, fn] of Object.entries(predicates)) {- Object.assign(error, { [name]: fn });- }-- return error as ClerkError & typeof predicates;+ return Object.assign({}, error, predicates) as ClerkError & typeof predicates;
}

This eliminates mutation and provides a cleaner API where error.isClerkApiResponseError() checks the error itself.

Based on coding guidelines: "Prefer readonly properties for immutable data structures."

🤖 Prompt for AI Agents
In packages/shared/src/errors/globalHookError.ts around lines 10 to 21, the
current implementation mutates the incoming error by assigning unbound predicate
functions to it; instead, return a new object that preserves the original error
properties (don’t mutate the input) and add readonly predicate methods that are
zero-argument closures which call the original type-guard predicates with the
original error value (e.g., () => isClerkApiResponseError(origError)); ensure
these added properties are non-writable/read-only (use Object.defineProperty or
equivalent) and return the result typed as ClerkError & typeof predicates so
consumers can call error.isClerkApiResponseError() without passing the error and
immutability is preserved.

⚠️ Potential issue | 🟠 Major

Restore the raw API errors array

Errors.raw is documented (packages/shared/src/types/state.ts Line 74) as “The raw, unparsed errors from the Clerk API.” Storing the aggregate ClerkAPIResponseError here drops the per-error payload consumers rely on. Keep raw as the API error list.

Apply this diff to preserve the original payload:

- parsedErrors.raw = [error];+ parsedErrors.raw = [...error.errors];
parsedErrors.global = [createClerkGlobalHookError(error)];
🤖 Prompt for AI Agents
In packages/clerk-js/src/core/signals.ts around lines 88 to 91, parsedErrors.raw
is being set to the aggregate ClerkAPIResponseError object instead of the
original per-error payload; change the assignment to preserve the API error list
by setting parsedErrors.raw to the error.errors array (or an empty array
fallback if needed) so consumers receive the raw, unparsed error entries, while
keeping parsedErrors.global as createClerkGlobalHookError(error).

Walkthrough

Adds createClerkGlobalHookError to wrap ClerkError objects with predicate helpers, re-exports ClerkError/createClerkGlobalHookError, and narrows several error typings from unknown to ClerkError | null, adjusting signal/event/state error routing and parsing accordingly.

Changes

Cohort / File(s)Summary
Error utility & barrel exports
packages/shared/src/errors/globalHookError.ts, packages/shared/src/error.ts
Add createClerkGlobalHookError(error: ClerkError) that attaches isClerkApiResponseError and isClerkRuntimeError predicates to the error; re-export ClerkError and createClerkGlobalHookError from the package barrel.
Shared types update
packages/shared/src/types/state.ts
Import ClerkGlobalHookError and change Errors.global from `unknown[]
Event payload typing
packages/clerk-js/src/core/events.ts
Change ResourceErrorPayload.error from unknown to `ClerkError
Signal handling & parsing
packages/clerk-js/src/core/signals.ts

State integration
packages/clerk-js/src/core/state.ts
Type onResourceError payload error as `ClerkError
ClerkAPIError constructor refactor
packages/shared/src/errors/clerkApiError.ts
Simplify constructor by building an inline parsedError object and assigning properties directly rather than using a separate parseJsonError helper.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • Focus review on:
    • packages/clerk-js/src/core/signals.ts: correctness of hasFieldErrors branch and population of raw/fields/global.
    • packages/shared/src/errors/globalHookError.ts: correct predicate attachment and typings returned.
    • Cross-package typing consistency where unknownClerkError | null was applied.
    • packages/shared/src/errors/clerkApiError.ts: ensure refactor preserves previous parsing semantics.

Poem

🐇 I tuck a tag on an error's sleeve,
Two tiny predicates snugly weave.
Fields sorted neat, globals wrapped tight,
I hop through types in the moonlit night. ✨

10-10: Add explicit return type annotation.

The function lacks an explicit return type annotation, which violates the coding guideline for public APIs.

Apply this diff:

-export function createClerkGlobalHookError(error: ClerkError) {+export function createClerkGlobalHookError(error: ClerkError): ClerkGlobalHookError {

Based on coding guidelines: "Always define explicit return types for functions, especially public APIs."

⚠️ Potential issue | 🟠 Major

Clarify predicate binding and avoid mutating the input parameter.

The function mutates the input error object by attaching predicates to it, which violates immutability principles. More critically, the attached predicates (isClerkApiResponseError, isClerkRuntimeError) are likely type guards that expect an error parameter (e.g., (error: unknown) => error is ClerkApiResponseError). Attaching them unbound creates a confusing API where consumers would need to call error.isClerkApiResponseError(error), which is redundant.

If the intent is to provide predicate methods that check the error itself, bind them by wrapping in closures:

 export function createClerkGlobalHookError(error: ClerkError) {
const predicates = {
- isClerkApiResponseError,- isClerkRuntimeError,+ isClerkApiResponseError: () => isClerkApiResponseError(error),+ isClerkRuntimeError: () => isClerkRuntimeError(error),
} as const;
- for (const [name, fn] of Object.entries(predicates)) {- Object.assign(error, { [name]: fn });- }-- return error as ClerkError & typeof predicates;+ return Object.assign({}, error, predicates) as ClerkError & typeof predicates;
}

This eliminates mutation and provides a cleaner API where error.isClerkApiResponseError() checks the error itself.

Based on coding guidelines: "Prefer readonly properties for immutable data structures."

🤖 Prompt for AI Agents
In packages/shared/src/errors/globalHookError.ts around lines 10 to 21, the
current implementation mutates the incoming error by assigning unbound predicate
functions to it; instead, return a new object that preserves the original error
properties (don’t mutate the input) and add readonly predicate methods that are
zero-argument closures which call the original type-guard predicates with the
original error value (e.g., () => isClerkApiResponseError(origError)); ensure
these added properties are non-writable/read-only (use Object.defineProperty or
equivalent) and return the result typed as ClerkError & typeof predicates so
consumers can call error.isClerkApiResponseError() without passing the error and
immutability is preserved.

⚠️ Potential issue | 🟠 Major

Restore the raw API errors array

Errors.raw is documented (packages/shared/src/types/state.ts Line 74) as “The raw, unparsed errors from the Clerk API.” Storing the aggregate ClerkAPIResponseError here drops the per-error payload consumers rely on. Keep raw as the API error list.

Apply this diff to preserve the original payload:

- parsedErrors.raw = [error];+ parsedErrors.raw = [...error.errors];
parsedErrors.global = [createClerkGlobalHookError(error)];
🤖 Prompt for AI Agents
In packages/clerk-js/src/core/signals.ts around lines 88 to 91, parsedErrors.raw
is being set to the aggregate ClerkAPIResponseError object instead of the
original per-error payload; change the assignment to preserve the API error list
by setting parsedErrors.raw to the error.errors array (or an empty array
fallback if needed) so consumers receive the raw, unparsed error entries, while
keeping parsedErrors.global as createClerkGlobalHookError(error).

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • Focus review on:
    • packages/clerk-js/src/core/signals.ts: correctness of hasFieldErrors branch and population of raw/fields/global.
    • packages/shared/src/errors/globalHookError.ts: correct predicate attachment and typings returned.
    • Cross-package typing consistency where unknownClerkError | null was applied.
    • packages/shared/src/errors/clerkApiError.ts: ensure refactor preserves previous parsing semantics.

🐇 I tuck a tag on an error's sleeve,
Two tiny predicates snugly weave.
Fields sorted neat, globals wrapped tight,
I hop through types in the moonlit night. ✨

⚠️ Potential issue | 🟠 Major

Clarify predicate binding and avoid mutating the input parameter.

The function mutates the input error object by attaching predicates to it, which violates immutability principles. More critically, the attached predicates (isClerkApiResponseError, isClerkRuntimeError) are likely type guards that expect an error parameter (e.g., (error: unknown) => error is ClerkApiResponseError). Attaching them unbound creates a confusing API where consumers would need to call error.isClerkApiResponseError(error), which is redundant.

If the intent is to provide predicate methods that check the error itself, bind them by wrapping in closures:

 export function createClerkGlobalHookError(error: ClerkError) {
const predicates = {
- isClerkApiResponseError,- isClerkRuntimeError,+ isClerkApiResponseError: () => isClerkApiResponseError(error),+ isClerkRuntimeError: () => isClerkRuntimeError(error),
} as const;
- for (const [name, fn] of Object.entries(predicates)) {- Object.assign(error, { [name]: fn });- }-- return error as ClerkError & typeof predicates;+ return Object.assign({}, error, predicates) as ClerkError & typeof predicates;
}

This eliminates mutation and provides a cleaner API where error.isClerkApiResponseError() checks the error itself.

Based on coding guidelines: "Prefer readonly properties for immutable data structures."

🤖 Prompt for AI Agents
In packages/shared/src/errors/globalHookError.ts around lines 10 to 21, the
current implementation mutates the incoming error by assigning unbound predicate
functions to it; instead, return a new object that preserves the original error
properties (don’t mutate the input) and add readonly predicate methods that are
zero-argument closures which call the original type-guard predicates with the
original error value (e.g., () => isClerkApiResponseError(origError)); ensure
these added properties are non-writable/read-only (use Object.defineProperty or
equivalent) and return the result typed as ClerkError & typeof predicates so
consumers can call error.isClerkApiResponseError() without passing the error and
immutability is preserved.

⚠️ Potential issue | 🟠 Major

Restore the raw API errors array

Errors.raw is documented (packages/shared/src/types/state.ts Line 74) as “The raw, unparsed errors from the Clerk API.” Storing the aggregate ClerkAPIResponseError here drops the per-error payload consumers rely on. Keep raw as the API error list.

Apply this diff to preserve the original payload:

- parsedErrors.raw = [error];+ parsedErrors.raw = [...error.errors];
parsedErrors.global = [createClerkGlobalHookError(error)];
🤖 Prompt for AI Agents
In packages/clerk-js/src/core/signals.ts around lines 88 to 91, parsedErrors.raw
is being set to the aggregate ClerkAPIResponseError object instead of the
original per-error payload; change the assignment to preserve the API error list
by setting parsedErrors.raw to the error.errors array (or an empty array
fallback if needed) so consumers receive the raw, unparsed error entries, while
keeping parsedErrors.global as createClerkGlobalHookError(error).

Walkthrough

Adds createClerkGlobalHookError to wrap ClerkError objects with predicate helpers, re-exports ClerkError/createClerkGlobalHookError, and narrows several error typings from unknown to ClerkError | null, adjusting signal/event/state error routing and parsing accordingly.

Changes

Cohort / File(s)Summary
Error utility & barrel exports
packages/shared/src/errors/globalHookError.ts, packages/shared/src/error.ts
Add createClerkGlobalHookError(error: ClerkError) that attaches isClerkApiResponseError and isClerkRuntimeError predicates to the error; re-export ClerkError and createClerkGlobalHookError from the package barrel.
Shared types update
packages/shared/src/types/state.ts
Import ClerkGlobalHookError and change Errors.global from `unknown[]
Event payload typing
packages/clerk-js/src/core/events.ts
Change ResourceErrorPayload.error from unknown to `ClerkError
Signal handling & parsing
packages/clerk-js/src/core/signals.ts

State integration
packages/clerk-js/src/core/state.ts
Type onResourceError payload error as `ClerkError
ClerkAPIError constructor refactor
packages/shared/src/errors/clerkApiError.ts
Simplify constructor by building an inline parsedError object and assigning properties directly rather than using a separate parseJsonError helper.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • Focus review on:
    • packages/clerk-js/src/core/signals.ts: correctness of hasFieldErrors branch and population of raw/fields/global.
    • packages/shared/src/errors/globalHookError.ts: correct predicate attachment and typings returned.
    • Cross-package typing consistency where unknownClerkError | null was applied.
    • packages/shared/src/errors/clerkApiError.ts: ensure refactor preserves previous parsing semantics.

🐇 I tuck a tag on an error's sleeve,
Two tiny predicates snugly weave.
Fields sorted neat, globals wrapped tight,
I hop through types in the moonlit night. ✨

⚠️ Potential issue | 🟠 Major

Clarify predicate binding and avoid mutating the input parameter.

The function mutates the input error object by attaching predicates to it, which violates immutability principles. More critically, the attached predicates (isClerkApiResponseError, isClerkRuntimeError) are likely type guards that expect an error parameter (e.g., (error: unknown) => error is ClerkApiResponseError). Attaching them unbound creates a confusing API where consumers would need to call error.isClerkApiResponseError(error), which is redundant.

If the intent is to provide predicate methods that check the error itself, bind them by wrapping in closures:

 export function createClerkGlobalHookError(error: ClerkError) {
const predicates = {
- isClerkApiResponseError,- isClerkRuntimeError,+ isClerkApiResponseError: () => isClerkApiResponseError(error),+ isClerkRuntimeError: () => isClerkRuntimeError(error),
} as const;
- for (const [name, fn] of Object.entries(predicates)) {- Object.assign(error, { [name]: fn });- }-- return error as ClerkError & typeof predicates;+ return Object.assign({}, error, predicates) as ClerkError & typeof predicates;
}

This eliminates mutation and provides a cleaner API where error.isClerkApiResponseError() checks the error itself.

Based on coding guidelines: "Prefer readonly properties for immutable data structures."

🤖 Prompt for AI Agents
In packages/shared/src/errors/globalHookError.ts around lines 10 to 21, the
current implementation mutates the incoming error by assigning unbound predicate
functions to it; instead, return a new object that preserves the original error
properties (don’t mutate the input) and add readonly predicate methods that are
zero-argument closures which call the original type-guard predicates with the
original error value (e.g., () => isClerkApiResponseError(origError)); ensure
these added properties are non-writable/read-only (use Object.defineProperty or
equivalent) and return the result typed as ClerkError & typeof predicates so
consumers can call error.isClerkApiResponseError() without passing the error and
immutability is preserved.

⚠️ Potential issue | 🟠 Major

Restore the raw API errors array

Errors.raw is documented (packages/shared/src/types/state.ts Line 74) as “The raw, unparsed errors from the Clerk API.” Storing the aggregate ClerkAPIResponseError here drops the per-error payload consumers rely on. Keep raw as the API error list.

Apply this diff to preserve the original payload:

- parsedErrors.raw = [error];+ parsedErrors.raw = [...error.errors];
parsedErrors.global = [createClerkGlobalHookError(error)];
🤖 Prompt for AI Agents
In packages/clerk-js/src/core/signals.ts around lines 88 to 91, parsedErrors.raw
is being set to the aggregate ClerkAPIResponseError object instead of the
original per-error payload; change the assignment to preserve the API error list
by setting parsedErrors.raw to the error.errors array (or an empty array
fallback if needed) so consumers receive the raw, unparsed error entries, while
keeping parsedErrors.global as createClerkGlobalHookError(error).

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • Focus review on:
    • packages/clerk-js/src/core/signals.ts: correctness of hasFieldErrors branch and population of raw/fields/global.
    • packages/shared/src/errors/globalHookError.ts: correct predicate attachment and typings returned.
    • Cross-package typing consistency where unknownClerkError | null was applied.
    • packages/shared/src/errors/clerkApiError.ts: ensure refactor preserves previous parsing semantics.

🐇 I tuck a tag on an error's sleeve,
Two tiny predicates snugly weave.
Fields sorted neat, globals wrapped tight,
I hop through types in the moonlit night. ✨

⚠️ Potential issue | 🟠 Major

Clarify predicate binding and avoid mutating the input parameter.

The function mutates the input error object by attaching predicates to it, which violates immutability principles. More critically, the attached predicates (isClerkApiResponseError, isClerkRuntimeError) are likely type guards that expect an error parameter (e.g., (error: unknown) => error is ClerkApiResponseError). Attaching them unbound creates a confusing API where consumers would need to call error.isClerkApiResponseError(error), which is redundant.

If the intent is to provide predicate methods that check the error itself, bind them by wrapping in closures:

 export function createClerkGlobalHookError(error: ClerkError) {
const predicates = {
- isClerkApiResponseError,- isClerkRuntimeError,+ isClerkApiResponseError: () => isClerkApiResponseError(error),+ isClerkRuntimeError: () => isClerkRuntimeError(error),
} as const;
- for (const [name, fn] of Object.entries(predicates)) {- Object.assign(error, { [name]: fn });- }-- return error as ClerkError & typeof predicates;+ return Object.assign({}, error, predicates) as ClerkError & typeof predicates;
}

This eliminates mutation and provides a cleaner API where error.isClerkApiResponseError() checks the error itself.

Based on coding guidelines: "Prefer readonly properties for immutable data structures."

🤖 Prompt for AI Agents
In packages/shared/src/errors/globalHookError.ts around lines 10 to 21, the
current implementation mutates the incoming error by assigning unbound predicate
functions to it; instead, return a new object that preserves the original error
properties (don’t mutate the input) and add readonly predicate methods that are
zero-argument closures which call the original type-guard predicates with the
original error value (e.g., () => isClerkApiResponseError(origError)); ensure
these added properties are non-writable/read-only (use Object.defineProperty or
equivalent) and return the result typed as ClerkError & typeof predicates so
consumers can call error.isClerkApiResponseError() without passing the error and
immutability is preserved.

⚠️ Potential issue | 🟠 Major

Restore the raw API errors array

Errors.raw is documented (packages/shared/src/types/state.ts Line 74) as “The raw, unparsed errors from the Clerk API.” Storing the aggregate ClerkAPIResponseError here drops the per-error payload consumers rely on. Keep raw as the API error list.

Apply this diff to preserve the original payload:

- parsedErrors.raw = [error];+ parsedErrors.raw = [...error.errors];
parsedErrors.global = [createClerkGlobalHookError(error)];
🤖 Prompt for AI Agents
In packages/clerk-js/src/core/signals.ts around lines 88 to 91, parsedErrors.raw
is being set to the aggregate ClerkAPIResponseError object instead of the
original per-error payload; change the assignment to preserve the API error list
by setting parsedErrors.raw to the error.errors array (or an empty array
fallback if needed) so consumers receive the raw, unparsed error entries, while
keeping parsedErrors.global as createClerkGlobalHookError(error).

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • Focus review on:
    • packages/clerk-js/src/core/signals.ts: correctness of hasFieldErrors branch and population of raw/fields/global.
    • packages/shared/src/errors/globalHookError.ts: correct predicate attachment and typings returned.
    • Cross-package typing consistency where unknownClerkError | null was applied.
    • packages/shared/src/errors/clerkApiError.ts: ensure refactor preserves previous parsing semantics.

Poem

🐇 I tuck a tag on an error's sleeve,
Two tiny predicates snugly weave.
Fields sorted neat, globals wrapped tight,
I hop through types in the moonlit night. ✨

10-10: Add explicit return type annotation.

The function lacks an explicit return type annotation, which violates the coding guideline for public APIs.

Apply this diff:

-export function createClerkGlobalHookError(error: ClerkError) {+export function createClerkGlobalHookError(error: ClerkError): ClerkGlobalHookError {

Based on coding guidelines: "Always define explicit return types for functions, especially public APIs."

⚠️ Potential issue | 🟠 Major

Clarify predicate binding and avoid mutating the input parameter.

The function mutates the input error object by attaching predicates to it, which violates immutability principles. More critically, the attached predicates (isClerkApiResponseError, isClerkRuntimeError) are likely type guards that expect an error parameter (e.g., (error: unknown) => error is ClerkApiResponseError). Attaching them unbound creates a confusing API where consumers would need to call error.isClerkApiResponseError(error), which is redundant.

If the intent is to provide predicate methods that check the error itself, bind them by wrapping in closures:

 export function createClerkGlobalHookError(error: ClerkError) {
const predicates = {
- isClerkApiResponseError,- isClerkRuntimeError,+ isClerkApiResponseError: () => isClerkApiResponseError(error),+ isClerkRuntimeError: () => isClerkRuntimeError(error),
} as const;
- for (const [name, fn] of Object.entries(predicates)) {- Object.assign(error, { [name]: fn });- }-- return error as ClerkError & typeof predicates;+ return Object.assign({}, error, predicates) as ClerkError & typeof predicates;
}

This eliminates mutation and provides a cleaner API where error.isClerkApiResponseError() checks the error itself.

Based on coding guidelines: "Prefer readonly properties for immutable data structures."

🤖 Prompt for AI Agents
In packages/shared/src/errors/globalHookError.ts around lines 10 to 21, the
current implementation mutates the incoming error by assigning unbound predicate
functions to it; instead, return a new object that preserves the original error
properties (don’t mutate the input) and add readonly predicate methods that are
zero-argument closures which call the original type-guard predicates with the
original error value (e.g., () => isClerkApiResponseError(origError)); ensure
these added properties are non-writable/read-only (use Object.defineProperty or
equivalent) and return the result typed as ClerkError & typeof predicates so
consumers can call error.isClerkApiResponseError() without passing the error and
immutability is preserved.

⚠️ Potential issue | 🟠 Major

Restore the raw API errors array

Errors.raw is documented (packages/shared/src/types/state.ts Line 74) as “The raw, unparsed errors from the Clerk API.” Storing the aggregate ClerkAPIResponseError here drops the per-error payload consumers rely on. Keep raw as the API error list.

Apply this diff to preserve the original payload:

- parsedErrors.raw = [error];+ parsedErrors.raw = [...error.errors];
parsedErrors.global = [createClerkGlobalHookError(error)];
🤖 Prompt for AI Agents
In packages/clerk-js/src/core/signals.ts around lines 88 to 91, parsedErrors.raw
is being set to the aggregate ClerkAPIResponseError object instead of the
original per-error payload; change the assignment to preserve the API error list
by setting parsedErrors.raw to the error.errors array (or an empty array
fallback if needed) so consumers receive the raw, unparsed error entries, while
keeping parsedErrors.global as createClerkGlobalHookError(error).

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • Focus review on:
    • packages/clerk-js/src/core/signals.ts: correctness of hasFieldErrors branch and population of raw/fields/global.
    • packages/shared/src/errors/globalHookError.ts: correct predicate attachment and typings returned.
    • Cross-package typing consistency where unknownClerkError | null was applied.
    • packages/shared/src/errors/clerkApiError.ts: ensure refactor preserves previous parsing semantics.

🐇 I tuck a tag on an error's sleeve,
Two tiny predicates snugly weave.
Fields sorted neat, globals wrapped tight,
I hop through types in the moonlit night. ✨

10-10: Add explicit return type annotation.

The function lacks an explicit return type annotation, which violates the coding guideline for public APIs.

Apply this diff:

-export function createClerkGlobalHookError(error: ClerkError) {+export function createClerkGlobalHookError(error: ClerkError): ClerkGlobalHookError {

Based on coding guidelines: "Always define explicit return types for functions, especially public APIs."

⚠️ Potential issue | 🟠 Major

Clarify predicate binding and avoid mutating the input parameter.

The function mutates the input error object by attaching predicates to it, which violates immutability principles. More critically, the attached predicates (isClerkApiResponseError, isClerkRuntimeError) are likely type guards that expect an error parameter (e.g., (error: unknown) => error is ClerkApiResponseError). Attaching them unbound creates a confusing API where consumers would need to call error.isClerkApiResponseError(error), which is redundant.

If the intent is to provide predicate methods that check the error itself, bind them by wrapping in closures:

 export function createClerkGlobalHookError(error: ClerkError) {
const predicates = {
- isClerkApiResponseError,- isClerkRuntimeError,+ isClerkApiResponseError: () => isClerkApiResponseError(error),+ isClerkRuntimeError: () => isClerkRuntimeError(error),
} as const;
- for (const [name, fn] of Object.entries(predicates)) {- Object.assign(error, { [name]: fn });- }-- return error as ClerkError & typeof predicates;+ return Object.assign({}, error, predicates) as ClerkError & typeof predicates;
}

This eliminates mutation and provides a cleaner API where error.isClerkApiResponseError() checks the error itself.

Based on coding guidelines: "Prefer readonly properties for immutable data structures."

🤖 Prompt for AI Agents
In packages/shared/src/errors/globalHookError.ts around lines 10 to 21, the
current implementation mutates the incoming error by assigning unbound predicate
functions to it; instead, return a new object that preserves the original error
properties (don’t mutate the input) and add readonly predicate methods that are
zero-argument closures which call the original type-guard predicates with the
original error value (e.g., () => isClerkApiResponseError(origError)); ensure
these added properties are non-writable/read-only (use Object.defineProperty or
equivalent) and return the result typed as ClerkError & typeof predicates so
consumers can call error.isClerkApiResponseError() without passing the error and
immutability is preserved.

⚠️ Potential issue | 🟠 Major

Restore the raw API errors array

Errors.raw is documented (packages/shared/src/types/state.ts Line 74) as “The raw, unparsed errors from the Clerk API.” Storing the aggregate ClerkAPIResponseError here drops the per-error payload consumers rely on. Keep raw as the API error list.

Apply this diff to preserve the original payload:

- parsedErrors.raw = [error];+ parsedErrors.raw = [...error.errors];
parsedErrors.global = [createClerkGlobalHookError(error)];
🤖 Prompt for AI Agents
In packages/clerk-js/src/core/signals.ts around lines 88 to 91, parsedErrors.raw
is being set to the aggregate ClerkAPIResponseError object instead of the
original per-error payload; change the assignment to preserve the API error list
by setting parsedErrors.raw to the error.errors array (or an empty array
fallback if needed) so consumers receive the raw, unparsed error entries, while
keeping parsedErrors.global as createClerkGlobalHookError(error).
