OpenAI、Codexエージェント間の委任を暗号化 — 開発者は見えないものをデバッグできるのか？
OpenAIのCodexは、エージェント間でやり取りされる指示を暗号化し、委任の詳細を開発者から隠すようになりました。これによりデバッグがブラックボックス化し、ワークフローが複雑になります。
openai has implemented mandatory encryption for instructions exchanged between codex agents, rendering the internal delegation process unreadable to developers. initially affecting gpt-5.5 before a partial rollback, the restriction now applies strictly to larger gpt-5.6 models sol and terra, leaving users unable to verify how tasks are distributed. reports indicate that the encrypted strings occasionally cause decryption errors and task handoff failures. while unconfirmed by openai, the move likely aims to prevent rival models from distilling valuable agent-to-agent training data, trading user transparency for intellectual property protection.
