为何重要
Codex Replay 会将迁移变成一个获客漏斗：导入在 Claude Code 上成功的工作，在 Codex 中重新运行，并在一个已经重要的任务上评估这次切换。
Reporting record
Finding
RuntimeWire established that Codex build 8881 contains a Claude Code-specific onboarding invitation that offers successful importers a Codex Replay plugin to rerun an imported coding task and compare results.
How we verified
Methods: documents, reverse engineering.
Static inspection of the uploaded openai-codex-electron archive, package version 26.908.40834, build 8881, found the invitation text, Claude Code eligibility predicate, codex-replay plugin installation flow, open_controller integration, and Codex Replay conversation handler.
RuntimeWire statically extracted and inspected the user-supplied archive, traced UI components, imports, eligibility checks, plugin-installation actions, and conversation handlers, and conducted public-source checks. The archive was not executed or modified, and no feature flags, plugins, account endpoints, purchases, or imported-task runs were tested.
Tested versions:
- Codex desktop client 26.908.40834 (build 8881)
Reproduction
RuntimeWire partially reproduced the finding.

Company response
RuntimeWire requested comment; the company had not responded by publication time.
OpenAI is building a Codex feature that invites developers to rerun work imported from Claude Code and compare the result, turning the migration process into a product trial built around a user's own coding task.
RuntimeWire found the feature, called Codex Replay, in production build 8881 of OpenAI's Codex desktop client, inspected on September 14th. The bundled interface tells eligible users: “重新运行你从另一个代理导入的任务并比较结果。”…
