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.

Claude Code v2.1.251

Auto mode can exit itself and tell you why

If your org's settings ban auto mode here, Claude Code exits it and tells you why.

Feature flag
tengu_auto_mode_config Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

Read once, for one account on one subscription tier, against v2.1.251. It isn't a statement about your account. What a flag value here can and cannot tell you

What

If your organization's managed settings disable auto mode for the kind of session you are in, Claude Code now leaves auto mode during its normal permission refresh and posts a notice in the conversation pointing at settings, rather than staying in a mode policy forbids.

Details
  • Triggers when the current mode is auto, or plan with auto queued up behind it, and the managed policy check says auto is not allowed here.
  • Skipped when admin policy settings failed to load with a non-warning error, unless the admin-survivor fallback is active.
  • Auto mode itself is controlled by the tengu_auto_mode_config gate, which resolves to enabled when the server sends no value.

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