Source Intelligence

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.

Telemetry for the effort nudge

Effort Levels

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.

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.

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

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.
