Class: ArtifactConflictError

Defined in: packages/core/src/domain/errors/artifact-conflict-error.ts:14

Thrown when a repository detects that an artifact file was modified on disk between the time it was loaded and the time a save was attempted.

This indicates a concurrent write — typically an LLM agent or another process wrote to the file after the caller loaded it. The caller should present the conflict to the user (e.g. via a diff of incomingContent vs currentContent) and offer the option to force-save or abort.

To force-save despite the conflict, retry the call with { force: true }.

Constructor​

new ArtifactConflictError(filename, incomingContent, currentContent): ArtifactConflictError

Defined in: packages/core/src/domain/errors/artifact-conflict-error.ts:54

Creates a new ArtifactConflictError with the conflicting contents for diff display.

Parameters​

filename​

string

The artifact filename where the conflict was detected

incomingContent​

string

The content the caller is trying to write

currentContent​

string

The content currently on disk

Returns​

ArtifactConflictError

stackTraceLimit​

static stackTraceLimit: number

Defined in: node_modules/.pnpm/@types+node@22.19.17/node_modules/@types/node/globals.d.ts:68

The Error.stackTraceLimit property specifies the number of stack frames collected by a stack trace (whether generated by new Error().stack or Error.captureStackTrace(obj)).

The default value is 10 but may be set to any valid JavaScript number. Changes will affect any stack trace captured after the value has been changed.

If set to a non-number value, or set to a negative number, stack traces will not capture any frames.

Accessors​

code​

Get Signature​

get code(): string

Defined in: packages/core/src/domain/errors/artifact-conflict-error.ts:20

Machine-readable error code for programmatic handling.

Returns​

string

Overrides​

SpecdError.code

currentContent​

Get Signature​

get currentContent(): string

Defined in: packages/core/src/domain/errors/artifact-conflict-error.ts:43

The content currently on disk at the time the conflict was detected. Use together with incomingContent to produce a diff for the user.

Returns​

string

filename​

Get Signature​

get filename(): string

Defined in: packages/core/src/domain/errors/artifact-conflict-error.ts:27

The filename of the artifact where the conflict was detected.

Returns​

string

incomingContent​

Get Signature​

get incomingContent(): string

Defined in: packages/core/src/domain/errors/artifact-conflict-error.ts:35

The content the caller is trying to write. Use together with currentContent to produce a diff for the user.

Returns​

string

Methods​

captureStackTrace()​

static captureStackTrace(targetObject, constructorOpt?): void

Defined in: node_modules/.pnpm/@types+node@22.19.17/node_modules/@types/node/globals.d.ts:52

Creates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called.

const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack;  // Similar to `new Error().stack`

The first line of the trace will be prefixed with ${myObject.name}: ${myObject.message}.

The optional constructorOpt argument accepts a function. If given, all frames above constructorOpt, including constructorOpt, will be omitted from the generated stack trace.

The constructorOpt argument is useful for hiding implementation details of error generation from the user. For instance:

function a() {
  b();
}

function b() {
  c();
}

function c() {
  // Create an error without stack trace to avoid calculating the stack trace twice.
  const { stackTraceLimit } = Error;
  Error.stackTraceLimit = 0;
  const error = new Error();
  Error.stackTraceLimit = stackTraceLimit;

  // Capture the stack trace above function b
  Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
  throw error;
}

a();
