DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Screen Reader Mode Reports Activation Source

Feature flag
tengu_ax_screen_reader Gate removed from the code

This release deleted the gate from the code while it was still reading on for the account this site reads, so the code path no longer asks a flag before running.

This account: on · anonymous baseline: on · compiled default in v2.1.206: not a boolean we can read

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 v2.1.206. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The screen reader mode status indicator now shows how the mode was activated (e.g., via environment variable or CLI flag) rather than just showing it's on.

Details
  • Old: [Accessible screen reader mode: on]
  • New: [Screen Reader Mode: on via {source}] when an activation source is known, or [Screen Reader Mode: on] otherwise.
  • The three possible {source} values are: "flag" (when the --ax-screen-reader CLI flag is passed), "env" (when the CLAUDE_AX_SCREEN_READER environment variable is set to a truthy value), and "settings" (when axScreenReader: true appears in the settings file). The priority order is flag → env → settings.
  • Activation is additionally gated by the GrowthBook feature flag tengu_ax_screen_reader. If the flag disables the feature, screen reader mode does not activate regardless of the CLI flag, env var, or settings value, and activationSource() returns undefined — so the on via {source} suffix will not appear even if an activation mechanism is present.
  • When the GrowthBook resolver is not yet available (e.g., before first-party initialization), the check defaults to true, allowing the mode to activate locally without a network round-trip.
Evidence

New format (search for "[Screen Reader Mode: on via"); activation sources (search for "activationSource()"); GrowthBook flag (search for "tengu_ax_screen_reader")

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