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 v2.1.219 24 Jul 2026

Workshop doc file snapshots are deduplicated

You'll notice

Useful2 Signal0

Elsewhere

Duplicate workshop doc snapshots are no longer written repeatedly, keeping your transcript smaller.

What

Repeated identical workshop doc snapshots are no longer written to the transcript, cutting duplicate large entries.

Details

The file_snapshot transcript writer remembers the last workshop doc recorded for the current session and skips writing an identical one again
It stores { sessionId, doc } after a successful record
The oversize guard ("Workshop doc over snapshot cap") is unchanged

Evidence

file_snapshot

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