Unofficial local-first session transfer for Codex and Claude Code

[ahmojo]

Maintainer disclosure: I maintain cct, an unofficial local-first tool for manually transferring Codex and Claude Code sessions.

It exports local session JSONL files into a .codexbundle, supports inspect/dry-run/import, and can remap project paths with --map-cwd OLD=NEW when moving between machines. It also supports best-effort Codex <-> Claude Code handoff via import --to.

What it is not: official OpenAI support, native cloud/account sync, Desktop cloud import, live sync, or a SQLite repair tool. It does not create account-owned cloud thread IDs and does not upload sessions anywhere.

Safety note: bundles can contain prompts, code, terminal output, file paths, attachments, and secrets.
