codex auto retry plugins

by songyb111-gachon

Auto-resume and auto-retry for interrupted Codex tasks on Windows. Waits out a usage limit (until the reset time Codex reports, e.g. for a 5-hour or weekly window), a rate limit or a temporary failure, then continues the exact same conversation, so long-running or overnight work keeps going while that conversation is open in the Codex app. Setup downloads a checksum-verified release from GitHub; after that the watcher runs locally, read-only against Codex state, conservative by design.
