README

cowork-to-chatgpt

Bring the full locally available Claude Cowork history into the same folders you use with ChatGPT and Codex.

OpenAI's native desktop import is the right first step. It imports supported setup, projects, and recent chats. This tool supplements that flow by converting the full locally persisted Cowork archive into isolated Markdown documentation, including history older than the native 30-day chat window.

Selected workspace folder  ─┐       existing files (preserved)
  CLAUDE.md                  ├────▶  AGENTS.md                 official instructions + memory
  memory/**/*.md             │       COWORK_INSTRUCTIONS.md    optional size overflow
Hidden session transcripts  ─┘       COWORK_HISTORY_*.md       supplemental Markdown

What is native and what is not

The distinction is deliberate:

File	OpenAI behavior
`AGENTS.md`	Documented Codex/ChatGPT desktop instruction file; imported Claude guidance is placed here
`COWORK_INSTRUCTIONS.md`	Ordinary Markdown overflow used only when `AGENTS.md` would exceed its documented limit
`COWORK_HISTORY_INDEX.md`	Ordinary Markdown index generated by this tool
`COWORK_HISTORY.md`	Ordinary Markdown history generated by this tool
