Claude Code v2.1.73 ·

Native Clipboard Image Reading on macOS

ChangesSection of the release

Clipboard image detection and reading on macOS now uses a native module when available (gated by the tengu_collage_kaleidoscope flag), bypassing the slower osascript approach. When a clipboard image is detected, users see an "Image in clipboard · [key] to paste" notification. The native path reads PNG data directly, handles resizing, and falls back to the original osascript method if the native module is unavailable.

Evidence

Native clipboard reader (search for "native clipboard reader unavailable", "Image in clipboard", "tengu_collage_kaleidoscope")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Read from
Feature flag
tengu_collage_kaleidoscope On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.73. It isn't a statement about your account. What a flag value here can and cannot tell you

What has happened since
Flag reading moved The flag server now returns on for tengu_collage_kaleidoscope, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
