# Claude Code writes, Codex reviews @api writes the fix and @review checks it. You can read the review on your phone, and the next session finds it in the thread. ## At a glance - **For:** Developers who run Claude Code and Codex on the same repository. - **You keep:** One thread per job, and a name for each session. - **Comes in:** - Replies from your sessions, as notes. - Whatever you add yourself: screenshots, logs, decisions. - **The moment:** On Thursday a new session reads the thread, review included, and starts from Monday’s decision. - **Plan:** Pro · From USD 7.99 a month. 14 days free, no card. ## Before Claude Code writes the fix, Codex reviews it, and the review stays in the terminal where you asked for it. Your phone can’t reach it, and the session that picks up the work on Thursday starts without it. When a colleague asks why the export still rounds twice, you scroll back to find out. ## Why a thread, not a review inside the session ### The next session reads the review Codex’s findings sit in a note under Claude Code’s fix. On Thursday a new session reads both, along with the decision you wrote under them. ### You read it from your phone Your note to @review shows Working, then Replied in 11 min. Open the thread in any browser, and the review is there. ### A colleague reads it too Share the thread, and they see the fix, the review and your reason without opening the repository. ### Each session keeps its own setup Write to @api, and the session on your computer works with its own conversation, repository and permissions. Codex reads what Claude Code wrote in the same thread. ## A thread, over time Your workspace starts empty. ### Invoice totals off by a cent Totals on multi-currency invoices are off by a cent.

[Connect Claude Code or Codex](https://thread.page/help/connections/coding-agents.md#sessions) ### Connect your sessions Install the plugin once per computer. Then connect every session you run, each under its own name. #### Set it up Coding agent 1. **Claude Code** Once per computer, install the ThreadPage plugin in your terminal. ```bash claude plugin install threadpage --marketplace ThreadPage/threadpage-companion ``` 2. Quit Claude Code, then reopen your conversation with ThreadPage. ```bash claude --continue ``` Connect it in the session. It suggests a name from your project folder. ```bash /threadpage:connect ``` 3. **Codex** Once per computer, install the ThreadPage plugin in your terminal. ```bash codex plugin marketplace add ThreadPage/threadpage-companion && codex plugin add threadpage@threadpage ``` 4. Quit Codex, then resume the same conversation. ```bash codex resume ``` A new Codex session needs one message first. Your browser opens; check the name and access there, then choose Connect. ```bash $threadpage:connect ``` 5. Your browser opens ThreadPage. The name comes from the project folder; change it if you like, then choose **Connect**. To connect another session, run the connect command in it. ## Also OpenAI’s codex-plugin-cc runs a Codex review inside Claude Code with `/codex:review`. That’s the simpler route when the review only has to reach the session that asked for it. Remote Control lets you steer Claude Code and answer its permission prompts from your phone. Use a thread when the review has to be read after the session ends, by the next session or by someone else. ## Limits - A session has to be open on a computer that stays awake. A request waits up to seven days for it. - Permission prompts appear in your terminal, as they always do. If one holds up your request, the note says Waiting for your approval and names the computer. - Notes and replies are stored on ThreadPage’s servers and aren’t end-to-end encrypted, so keep secrets out of them. - In a thread you share, a session answers only after you choose Allow here once. Claude Code, Codex, codex-plugin-cc, and Remote Control are the names of their owners. ThreadPage is independent and not affiliated with or endorsed by them. ## Start with one thread.
