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.

Claude Code v2.1.101

File Attribution Tracking

What

Claude Code now tracks per-file edit contributions by computing the magnitude of changes, enabling better understanding of how much Claude contributed to each file.

Details
  • Computes claudeContribution based on the diff between old and new content for each edit
  • Tracks both regular edits and file deletions
  • Logs attribution events: "Attribution: Tracked N chars for path/to/file"
  • Uses content hashing to detect unchanged files
  • Supports bulk edit tracking for batch operations
Evidence

File attribution system (search for "Attribution: Tracked")

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