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 v2.1.2

Improved Git Commit Attribution for Amends

What

Git commit attribution now properly handles git commit --amend operations by recalculating and replacing existing Claude trailers.

Details
  • Detects when a commit command includes --amend
  • Strips existing Claude attribution trailers before recalculating
  • Properly replaces Claude-Generated-By, Claude-Steers, Claude-Permission-Prompts, Claude-Escapes, and Claude-Plan fields
  • Prevents duplicate or stale attribution data in amended commits
Evidence

v$7() at line 531681 (amend attribution handler, contains "--amend" detection and trailer replacement)

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