"body": "## Summary of Changes\n\nHello @WhiteElephantIsNotARobot, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!\n\n此拉取请求旨在解决 GitHub Actions `workflow_dispatch` 因输入数据（特别是上下文信息）超出 64KB 限制而失败的问题。通过引入智能的数据处理策略，它首先尝试将超大上下文数据存储到一个新的 GitHub Issue 中，从而避免直接在工作流输入中传递所有数据。如果此方法不可行或数据仍然过大，系统将按照预定义的优先级（如丢弃 diff 内容、截断评论历史等）对上下文进行精简，确保工作流能够成功触发，提高了系统的鲁棒性。\n\n### Highlights\n\n* **解决 GitHub Actions 输入限制**: 引入新机制，处理 `workflow_dispatch` 输入数据超过 64KB 限制导致的工作流失败。\n* **大上下文数据 Issue 存储**: 当上下文或任务文本过大时，尝试创建 GitHub Issue 存储数据，并通过 `repository_dispatch` 传递 Issue 编号，绕过 `workflow_dispatch` 大小限制。\n* **分级上下文截断策略**: 若数据仍超限或无法存储到 Issue，系统将按优先级丢弃或截断数据：首先 `diff_content`，然后 `comments_history`（保留最近 5 条），接着 `review_comments_batch`，最后 `reviews_history`。\n* **新增 `create_issue` 函数**: 添加异步函数 `create_issue`，用于创建 GitHub Issue 存储超大上下文数据。\n\n\n\n\n\n\n\n\n\n<details>\n<summary><b>Using Gemini Code Assist</b></summary>\n<br>\n\nThe full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips.\n\n<b>Invoking Gemini</b>\n\nYou can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.

"body": "## Code Review\n\n本次 PR 旨在解决当上下文超过 GitHub Actions 64KB 限制时导致 workflow dispatch 失败的问题。解决方案是当上下文过大时，优先尝试创建一个 issue 来存储数据，如果失败或数据不是特别大但仍超限，则按优先级丢弃部分上下文（如 diff、评论历史等）。这个思路是合理的，但我在实现中发现了一个关键问题和一处可优化的代码结构。\n\n主要问题在于，当使用 issue 存储方案时，触发工作流的 payload 结构不正确，使用了 `client_payload` 而非 `inputs`，这将导致工作流无法接收到参数。此外，上下文截断部分的逻辑存在大量重复代码，可以进行重构以提高可读性和可维护性。请查看具体的审查评论。",
