Claude Code v2.1.122 ·

Plan Mode Prompt Consolidation

Entry
JSON All of v2.1.122
EntryKind: in v2.1.122,
ChangesSection of the release

The three separate plan mode phase-4 prompt variants (controlled by tengu_pewter_ledger returning "trim", "cut", or "cap") have been removed. The feature flag tengu_pewter_ledger is no longer read. Plan mode now uses a single consolidated prompt.

Evidence

Removed A98() function and pU1/BU1/FU1 prompt variants (previously searched for "tengu_pewter_ledger" — now absent from v2.1.122)

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

tengu_pewter_ledger 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.

What has happened since
Flag reading moved The flag server now returns "OFF" for tengu_pewter_ledger, 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.
