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.

Transcript Persistence Warnings

New persistent warning banners appear in the TUI when transcript saving is suppressed or failing:

  • If CLAUDE_CODE_SKIP_PROMPT_HISTORY is set: shows "Transcript saving is off — CLAUDE_CODE_SKIP_PROMPT_HISTORY is set" with "· --resume will not find this session; if unintended, unset it and restart"
  • If running as a child session (inherited CLAUDE_CODE_CHILD_SESSION marker): shows "Transcript saving is off — inherited CLAUDE_CODE_CHILD_SESSION marker" with "· restart with CLAUDE_CODE_FORCE_SESSION_PERSISTENCE=1 to keep future transcripts"
  • If transcript writes are failing: shows "Transcript writes are failing (…)" with "· recent messages may not be saved for resume" — error codes are translated: ENOSPC → "disk full", EROFS → "read-only filesystem", EDQUOT → "disk quota exceeded", etc.
Evidence

Persistence suppressed notification (search for "Transcript saving is off") and transcript writer degraded notification (search for "Transcript writes are failing")

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