Changelog

[Unreleased]

[1.1.0] - 2026-10-07

Added

• Added console: true to text output items produced by console.*, so hosts can tell them apart from text() output

[1.0.4] - 2026-10-05

Changed

• Built-ins are frozen and built-in globals are read-only before the script runs, so patches such as Array.prototype.toJSON = ... have no effect. Instances can still override constructor, name, message, toString, toLocaleString, valueOf, toJSON, and Object.prototype members (#10444)

Fixed

• Fixed a script that patched built-ins crashing the host process and leaving execute() unsettled. Malformed payloads from the worker now fail the execution with a sandbox error (#10444)

[1.0.3] - 2026-10-05

[1.0.2] - 2026-10-04

[1.0.1] - 2026-10-03

Fixed

• Fixed scripts that print in a loop growing the host's memory until it crashes: output is limited to MAX_OUTPUT_CHARS (16 Mi) characters and MAX_OUTPUT_ITEMS (100000) items, and a script past either limit fails with a RangeError (#10283)

[1.0.0] - 2026-10-01

Added

• Added renderToolOutputType(), the type a tool call resolves to.

Changed

• Reading a member of tools or of a global namespace that does not exist now throws an error naming the close matches, instead of returning undefined. Use "name" in tools to check for a tool. store() size errors explain what the store is for.

[0.99.2] - 2026-09-30

Changed

• Allowed CodemodeSandbox.workerUrl to be a string, as required for embedded worker entrypoints in Bun compiled executables (#10204).

Fixed

• Fixed image() accepting malformed base64 data and unsupported image types. It now throws a TypeError unless the data is valid base64 of a PNG, JPEG, GIF, or WebP image, derives the MIME type from the image signature instead of the declared type, and strips line breaks from wrapped base64 (#10215).

[0.99.1] - 2026-09-29

[0.99.0] - 2026-09-29

Added

• Initial spike: CodemodeSandbox runs model-written JavaScript in a worker thread and exposes injected tools as tools.<name>(args) async functions.
