Auto mode falls back to real defaults when remote config is unavailable

You'll notice
Useful3 Signal3
Auto Mode not in their notes

Auto mode uses sensible built-in defaults when remote config is missing, instead of everything off.

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.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.236: not a boolean we can read

Read once, for one account on one subscription tier, against v2.1.236. It isn't a statement about your account. What a flag value here can and cannot tell you

DISABLE_GROWTHBOOK
What

Auto mode used to read an empty config, meaning every option off, whenever the remote config key tengu_auto_mode_config was missing. All readers now go through one helper that applies a frozen built-in default instead. This only kicks in when the key is absent and GrowthBook is unavailable or DISABLE_GROWTHBOOK is set.

Details
  • Defaults on: two-stage classifier, same-turn sibling context, JSONL transcript, edit-removal visibility (capped at 3000), repo visibility, git status type.
  • Defaults off: outcome visibility, git status uploads.
  • Per-model severity thresholds ship as part of the same default.
Evidence

tengu_auto_mode_config

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