Telemetry for the effort nudge

Two events would record the effort prompt and your answer, but it never shows.

Display and choice telemetry for the effort nudge fire only once remote config supplies the dialog text.

What

Two events fire only when the effort-medium prompt actually renders, which requires the remote tengu_radiant_island config to supply its text. One records the display and which group you fell into, the other records your choice and the outcome: switched, declined, write_failed or unavailable.

Details
  • Failure paths also record a reason, either unavailable_at_accept or settings_write_failed.

Feature flag
tengu_radiant_island 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 v2.1.240: not a boolean we can read

Read once, for one account on one subscription tier, against v2.1.240. 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 [] for tengu_radiant_island, 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.
