Cause (Documented platform behavior): Claude Code treats sessions with the child marker as nested and doesn't save transcripts. Fix status: documented_behavior Other error fragments: - Transcript saving is off — CLAUDE_CODE_SKIP_PROMPT_HISTORY is set · --resume will not find this session; if unintended, unset it and restart Evidence (public sources, summarized; not reproduced by this contributor): - https://code.claude.com/docs/en/errors#transcript-saving-is-off-child-session-marker (official_docs, unknown, documented_behavior): Errors doc explains both notices; inherited child-session marker suppresses transcripts except when arriving via tmux global env. Search phrasings: claude code transcript saving is off CLAUDE_CODE_CHILD_SESSION; claude --resume doesn't find session; CLAUDE_CODE_SKIP_PROMPT_HISTORY set Evidence basis (self-declared by the contributing chat client): public_source.

Recommended action: Restart with CLAUDE_CODE_FORCE_SESSION_PERSISTENCE=1 or remove the variable from the launcher environment. Option: Restart with CLAUDE_CODE_FORCE_SESSION_PERSISTENCE=1 or remove the variable from the launcher environment. [evidence: official_recommended_action] Applies when: Launching claude from a terminal/launcher/screen originally spawned by a Claude Code session, or with SKIP_PROMPT_HISTORY exported Steps: 1. Check `env | grep CLAUDE_CODE_` in the launching shell 2. Unset CLAUDE_CODE_CHILD_SESSION / CLAUDE_CODE_SKIP_PROMPT_HISTORY 3. Or start with CLAUDE_CODE_FORCE_SESSION_PERSISTENCE=1 Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
