Anthropic 推出 Claude Code 跨会话通信功能，解决我们常用的跨会话copy问题

Anano · 2026 年8 月 9 日 17:56

人工智能初创公司 Anthropic 今日为其 AI 编程工具 Claude Code 推出了一项重大更新。在最新的 v2.1.224 版本中，运行于 macOS 和 Linux 平台的 Claude Code 正式支持跨会话消息传递功能（Cross-session messaging），允许不同的终端会话之间互相发送信息、共享发现、解答疑问并协调工作。

对于习惯同时运行多个 Claude Code 实例来处理同一项目不同模块的技术人员而言，这一功能大幅简化了多任务协作的复杂程度。

根据官方说明，该功能的典型应用场景包括提交分析结论、协调并行工作树（worktrees）、获取长时间运行任务的最新状态，以及实现跨机器的响应沟通。在操作体验上，用户无需花心思构思具体的消息结构，只需提供核心沟通意图，Claude 即可自动生成完整的文本消息

是的，两个很像，现在越来越趋同演化了

联想到Codex就来气，上个月搞了个实验性功能的paginated thread history,各种困难了…一开始时候resume完全用不来了，各种bug，不知道这个paginated和legacy双轨要到什么时候

Paginated history can reconstruct completed turns as “interrupted” on resume

bug CLI app-server

## Summary After upgrading Codex CLI from `0.146.0` to `0.147.0`, previously co…mpleted conversations no longer replay correctly with `codex resume`. The resumed conversation shows only the beginning of the first turn and then: ```text Conversation interrupted - tell the model what to do differently. Something went wrong? Hit `/feedback` to report the issue. ``` However, the underlying rollout JSONL is complete and contains the full turn, including subsequent assistant/tool activity and an explicit `task_complete`. This appears to be a bug in paginated history reconstruction rather than missing or corrupted rollout data. ## Environment - Codex CLI: `0.147.0` - Previously: `0.146.0` - OS: Linux - Installation: native Codex install script ## Reproduction 1. Have an existing conversation containing one or more normally completed turns. 2. Upgrade to `0.147.0`. 3. Resume the conversation with: ```bash codex resume ``` 4. The TUI displays only the beginning of the conversation and then marks it as interrupted. ## Evidence The underlying rollout JSONL remains intact. For the affected turn, the rollout contains: ```text task_started ... assistant/tool activity ... final assistant output task_complete ``` There are also later completed turns in the same rollout. I queried `codex app-server` directly using `thread/resume` with paginated history. The app-server returned the affected historical turn approximately as: ```text thread status: idle history mode: paginated turn status: interrupted items: 4 ``` This is inconsistent with the canonical rollout, where the same turn continues substantially further and ends with `task_complete`. Using `excludeTurns: false` did not restore the full history; the thread was still returned in paginated mode with the same truncated/interrupted reconstruction. ## Troubleshooting attempted I tried: - downgrading to `0.146.0`; - deleting and rebuilding the Codex SQLite state database; - restarting Codex and resuming the same conversation. The problem remained. The rollout JSONL itself remained complete. ## Suspected failure mode It appears that paginated history reconstruction is materialising only a partial fragment of a completed turn. Because the completion boundary is not included in the reconstructed fragment, the turn is subsequently treated as interrupted even though the rollout contains a valid `task_complete`. Conceptually: ```text complete rollout ↓ paginated history reconstruction ↓ partial historical turn ↓ completion boundary not observed ↓ turn classified as interrupted ↓ TUI displays “Conversation interrupted” ``` The incorrect `interrupted` status is already present in the `thread/resume` app-server response, so the problem does not appear to be limited to TUI rendering. ## Expected behaviour Completed historical turns should be reconstructed as completed and their full conversation history should remain available after resume. ## Actual behaviour A completed historical turn is returned as interrupted with only a small subset of its items, and later history is not displayed. ## Data integrity The underlying rollout data appears to be intact. This looks like a paginated history reconstruction/migration issue rather than conversation data loss.
