The Chain — your task moves between AI coding agents without re-explaining your repo

The Chain · the crown jewel

Claude clocks out. Codex clocks in.
Your task carries over.

The free core of Renitor. Driving the official CLIs on your subscription? When an agent hits its 5-hour usage window, your task moves to the next agent in seconds — goal, diff, errors and decisions intact — and comes back when the window resets.

Shift A — Claude Code● limit reached

Shift B — Codex● active
$ codex — continuing from handoff
✓ context loaded — goal · diff · errors
✓ refactor finished · tests green
… window resets …
$ claude --resume
"While I was away, Codex finished
 the refactor."
▶ the whole loop, replayed — limit hit → handoff → handback, the goal, diff and decisions moving with you
Detected at the moment of pain

The extension watches your terminal and offers the handoff the second the limit banner appears. One click.

A briefing, not a chat dump

Goal auto-read from the agent's own session log, git diff, captured errors, project rules — secrets scrubbed twice.

The way back is native

When you head back, one click injects a session into Claude's own history. claude --resume — and it resumes from the continuation record.
