Pi v0.77.0 - 更新日志

### 新功能 - **Claude Opus 4.8 支持** - 添加了 Anthropic Claude Opus 4.8 的元数据，并更新了 Opus 自适应思考的覆盖范围。 - **选择性禁用工具** - `--exclude-tools` / `-xt` 可禁用特定的内置、扩展或自定义工具，同时保留其余工具可用。详见 [工具选项](https://github.com/earendil-works/pi/blob/v0.77.0/packages/coding-agent/docs/usage.md#tool-options)。 - **无头模式 Codex 订阅登录** - `/login` 支持使用设备码认证进行 ChatGPT Plus/Pro Codex 订阅登录。详见 [订阅](https://github.com/earendil-works/pi/blob/v0.77.0/packages/coding-agent/docs/providers.md#subscriptions) 和 [OpenAI Codex](https://github.com/earendil-works/pi/blob/v0.77.0/packages/coding-agent/docs/providers.md#openai-codex)。 - **流式感知扩展输入** - 扩展程序可通过 `InputEvent.streamingBehavior` 区分空闲提示词、流式处理中的转向指令以及排队中的后续提示。详见 [输入事件](https://github.com/earendil-works/pi/blob/v0.77.0/packages/coding-agent/docs/extensions.md#input-events)。 ### 新增 - 新增 `--exclude-tools` / `-xt` 参数，用于禁用特定的内置、扩展或自定义工具，同时保留其余工具可用（[#5109](https://github.com/earendil-works/pi/issues/5109)）。 - 新增 OpenAI Codex 订阅的设备码登录功能，作为可选的无头模式替代方案，同时默认保留浏览器登录方式（[#4911](https://github.com/earendil-works/pi/pull/4911) by [@vegarsti](https://github.com/vegarsti)）。 - 在扩展输入事件中新增 `streamingBehavior`，使扩展程序能够区分空闲提示词、流式处理中的转向指令以及排队中的后续提示（[#5107](https://github.com/earendil-works/pi/pull/5107) by [@DanielThomas](https://github.com/DanielThomas)）。 - 为 Anthropic 新增 Claude Opus 4.8 模型元数据，并更新 Opus 自适应思考覆盖范围以使用它。 ### 修复 - 修复启动时间输出，使 `readPipedStdin` 不再包含 `createAgentSessionRuntime` 的工作耗时（[#4829](https://github.com/earendil-works/pi/issues/4829)）。 - 修复 OpenRouter DeepSeek V4 `xhigh` 推理元数据，以保留 OpenRouter 的原生努力级别，而非发送 DeepSeek 的 `max` 级别（[#4801](https://github.com/earendil-works/pi/issues/4801)）。 - 修复自定义会话目录问题，使当前文件夹的恢复/继续查找保持在活动 cwd 范围内，而所有会话列表则覆盖自定义目录。 - 修复 SIGTERM/SIGHUP 退出时的扩展 `session_shutdown` 清理及终端恢复：信号触发的关机现在会在任何终端写入前触发 `session_shutdown`，且 SIGHUP 不再硬退出，因此即使终端已消失，扩展资源（如 socket）也能被正确释放（[#5080](https://github.com/earendil-works/pi/issues/5080)）。 - 修复键盘协议协商，忽略不匹配或延迟的终端响应，避免误判为 Kitty 键盘协议（[#5091](https://github.com/earendil-works/pi/pull/5091) by [@mitsuhiko](https://github.com/mitsuhiko)）。 - 通过更新原生剪贴板插件至 napi-rs 3.x，修复 MSYS2 ucrt64 Node.js 环境下的 Windows 启动崩溃问题（[#5028](https://github.com/earendil-works/pi/issues/5028)）。 - 修复 API 密钥和 Header 配置解析，将纯字符串视为字面量，支持 `$ENV_VAR` / `${ENV_VAR}` 插值及 `$!` 感叹号转义，并要求配置文件使用显式环境变量语法，避免 Windows 不区分大小写的环境变量匹配破坏字面量密钥（[#5095](https://github.com/earendil-works/pi/issues/5095)）。 - 修复会话销毁逻辑，中止正在进行的代理、压缩、分支摘要、重试和 bash 任务（[#5029](https://github.com/earendil-works/pi/pull/5029) by [@TerminallyChilI](https://github.com/TerminallyChilI)）。 - 修复 `pi.getAllTools()`，暴露每个工具的 `promptGuidelines`，以满足需要按工具归属指南的扩展程序需求（[#4879](https://github.com/earendil-works/pi/issues/4879)）。 - 修复从 Anthropic 扩展思考会话切换后 OpenAI Codex Responses 的重播问题，通过为转换后的思考/文本块生成唯一的回退消息项 ID（[#5148](https://github.com/earendil-works/pi/issues/5148)）。 - 修复 Anthropic 兼容的重播功能，针对返回空思考签名的提供商，新增可选的 `allowEmptySignature` 兼容标志（[#4464](https://github.com/earendil-works/pi/issues/4464)）。 - 修复 OpenAI 和 OpenRouter GPT-5.5 Pro 思考级别元数据，仅暴露支持的 medium、high 和 xhigh 级别。 - 修复 OpenCode Go Kimi K2.6 关闭思考的请求，使其正确发送 `thinking: "none"`（[#5078](https://github.com/earendil-works/pi/issues/5078)）。 - 修复 Xiaomi Token Plan 模型元数据，省略不支持的 `mimo-v2-flash` 变体（[#5075](https://github.com/earendil-works/pi/issues/5075)）。 - 修复由 `agent_end` 扩展处理器排队的后续提示消息，使其在代理变为空闲前排空（[#5115](https://github.com/earendil-works/pi/pull/5115) by [@DanielThomas](https://github.com/DanielThomas)）。 - 修复扩展输入事件，仅对实际在流式处理期间排队的提示词报告 `streamingBehavior`（[#5107](https://github.com/earendil-works/pi/pull/5107) by [@DanielThomas](https://github.com/DanielThomas)）。 - 修复系统提示词中的工具选择引导，避免优先推荐不可用的文件探索工具（[#5132](https://github.com/earendil-works/pi/issues/5132)）。 - 修复 fenced `diff` 代码块及其他 highlight.js 作用域，在替换为 `cli-highlight` 后保持主题感知的语法高亮颜色（[#5092](https://github.com/earendil-works/pi/issues/5092)）。

### New Features - **Claude Opus 4.8 support** - Adds Anthropic Claude Opus 4.8 metadata and updates Opus adaptive-thinking coverage. - **Selective tool disablement** - `--exclude-tools` / `-xt` disables specific built-in, extension, or custom tools while leaving the rest available. See [Tool Options](https://github.com/earendil-works/pi/blob/v0.77.0/packages/coding-agent/docs/usage.md#tool-options). - **Headless Codex subscription login** - `/login` can use device-code auth for ChatGPT Plus/Pro Codex subscriptions. See [Subscriptions](https://github.com/earendil-works/pi/blob/v0.77.0/packages/coding-agent/docs/providers.md#subscriptions) and [OpenAI Codex](https://github.com/earendil-works/pi/blob/v0.77.0/packages/coding-agent/docs/providers.md#openai-codex). - **Streaming-aware extension input** - extensions can distinguish idle prompts, mid-stream steers, and queued follow-ups with `InputEvent.streamingBehavior`. See [Input Events](https://github.com/earendil-works/pi/blob/v0.77.0/packages/coding-agent/docs/extensions.md#input-events). ### Added - Added `--exclude-tools` / `-xt` to disable specific built-in, extension, or custom tools while leaving the rest available ([#5109](https://github.com/earendil-works/pi/issues/5109)). - Added OpenAI Codex subscription device-code login as a selectable headless alternative while keeping browser login as the default ([#4911](https://github.com/earendil-works/pi/pull/4911) by [@vegarsti](https://github.com/vegarsti)). - Added `streamingBehavior` to extension input events so extensions can distinguish idle prompts from mid-stream steers and queued follow-ups ([#5107](https://github.com/earendil-works/pi/pull/5107) by [@DanielThomas](https://github.com/DanielThomas)). - Added Claude Opus 4.8 model metadata for Anthropic and updated Opus adaptive-thinking coverage to use it. ### Fixed - Fixed startup timing output so `readPipedStdin` no longer includes `createAgentSessionRuntime` work ([#4829](https://github.com/earendil-works/pi/issues/4829)). - Fixed OpenRouter DeepSeek V4 `xhigh` reasoning metadata to preserve OpenRouter's native effort instead of sending DeepSeek's `max` effort ([#4801](https://github.com/earendil-works/pi/issues/4801)). - Fixed custom session directories so current-folder resume/continue lookups stay scoped to the active cwd while all-session listings cover the custom directory. - Fixed SIGTERM/SIGHUP exits to run extension `session_shutdown` cleanup and restore the terminal: signal-triggered shutdown now emits `session_shutdown` before any terminal writes, and SIGHUP no longer hard-exits, so extension resources (e.g. sockets) are released even when the terminal is gone ([#5080](https://github.com/earendil-works/pi/issues/5080)). - Fixed keyboard protocol negotiation to ignore mismatched or delayed terminal responses, avoiding false Kitty keyboard protocol detection ([#5091](https://github.com/earendil-works/pi/pull/5091) by [@mitsuhiko](https://github.com/mitsuhiko)). - Fixed Windows startup crashes under MSYS2 ucrt64 Node.js by updating the native clipboard addon to napi-rs 3.x ([#5028](https://github.com/earendil-works/pi/issues/5028)). - Fixed API key and header config resolution to treat plain strings as literals, support `$ENV_VAR` / `${ENV_VAR}` interpolation and `$!` bang escaping, and require explicit env syntax for config files, avoiding Windows case-insensitive env matches corrupting literal keys ([#5095](https://github.com/earendil-works/pi/issues/5095)). - Fixed session disposal to abort in-flight agent, compaction, branch summary, retry, and bash work ([#5029](https://github.com/earendil-works/pi/pull/5029) by [@TerminallyChilI](https://github.com/TerminallyChilI)). - Fixed `pi.getAllTools()` to expose each tool's `promptGuidelines` for extensions that need per-tool guideline attribution ([#4879](https://github.com/earendil-works/pi/issues/4879)). - Fixed OpenAI Codex Responses replay after switching from Anthropic extended-thinking sessions by generating unique fallback message item IDs for converted thinking/text blocks ([#5148](https://github.com/earendil-works/pi/issues/5148)). - Fixed Anthropic-compatible replay for providers that return empty thinking signatures by adding an opt-in `allowEmptySignature` compatibility flag ([#4464](https://github.com/earendil-works/pi/issues/4464)). - Fixed OpenAI and OpenRouter GPT-5.5 Pro thinking level metadata to expose only supported medium, high, and xhigh efforts. - Fixed OpenCode Go Kimi K2.6 thinking-off requests to send `thinking: "none"` ([#5078](https://github.com/earendil-works/pi/issues/5078)). - Fixed Xiaomi Token Plan model metadata to omit unsupported `mimo-v2-flash` variants ([#5075](https://github.com/earendil-works/pi/issues/5075)). - Fixed follow-up messages queued by `agent_end` extension handlers to drain before the agent becomes idle ([#5115](https://github.com/earendil-works/pi/pull/5115) by [@DanielThomas](https://github.com/DanielThomas)). - Fixed extension input events to report `streamingBehavior` only for prompts actually queued during streaming ([#5107](https://github.com/earendil-works/pi/pull/5107) by [@DanielThomas](https://github.com/DanielThomas)). - Fixed system prompt tool-selection guidance to avoid preferring unavailable file exploration tools ([#5132](https://github.com/earendil-works/pi/issues/5132)). - Fixed fenced `diff` code blocks and other highlight.js scopes to keep theme-aware syntax colors after the `cli-highlight` replacement ([#5092](https://github.com/earendil-works/pi/issues/5092)).
