Conversation
A Turn's result usage sums every request of the native Conversation: on a resumed Conversation its input_tokens was 31,422 while the latest request's prompt was 8,499. hostUsage fell back to input_tokens for context, so each Turn ended by reporting the Conversation's cumulative input as its context, growing with every Turn until the next step replaced it. Estimate context only from a step's usage, which describes one request, and count that request's whole prompt. agy reports the cached part separately as cache_read_tokens (a follow-up request's cache_read_tokens is about the previous request's prompt), so input_tokens alone undercounted context whenever the prompt cache was hit. Result usage still publishes its totals, but carries context only when agy names it explicitly. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

codexhost v0.15.0 ## What's New Import native Sessions from a selected Host, answer multi-select questions, and use Grok's native questions. This release also adds Antigravity usage statistics and improves conversation reliability across Claude Code, Pi, Windows, and Codex Desktop. 支持从所选 Host 导入原生 Session、回答多选问题，并接入 Grok 原生提问。本版还新增 Antigravity 用量统计，改进 Claude Code、Pi、Windows 和 Codex Desktop 的会话可靠性。 ### Features - Select a local or remote Host for Session import, keeping import and opening on the selected machine; support macOS Broker-backed imports for Claude Code, Cursor CLI, CodeBuddy, and WorkBuddy (BytePioneer-AI#207) - Answer external Harness multi-select questions in a shared card, with accompanying single-choice and text fields and drafts retained while switching chats (BytePioneer-AI#625) - Answer Grok's native single-choice, multi-select, and text questions, with cancellation and native withdrawal support (BytePioneer-AI#625) - Read Antigravity's native historical request and Token usage, including Sessions created outside codexhost; model and cost information remain unavailable when absent from native records (BytePioneer-AI#588) ### Fixes - Steer Claude Code continuations within the same Turn without stopping background Subagents, and keep accepted instructions attached to that Turn (BytePioneer-AI#617) - Release Claude Code Turns after refused Subagent messages, and allow Fork and message-edit recovery after entering a native worktree (BytePioneer-AI#626, BytePioneer-AI#629) - Improve Pi's large-history RPC performance and ignore late replies to expired read-only queries without faulting the Session (BytePioneer-AI#607) - Recover stale Windows Mapping Store locks when a PID has been reused by another process (BytePioneer-AI#627) - Keep Antigravity questions working across Turns, preserve the project working directory, and bound process cleanup waits (BytePioneer-AI#586) - Keep Antigravity Conversation totals separate from current context usage (BytePioneer-AI#587) - Disable background self-update by default for Host-started Antigravity processes on Windows and macOS, while retaining explicit updates (BytePioneer-AI#585) - Explain unavailable ZCode plans or quotas without asking an already signed-in account to log in again (BytePioneer-AI#621) - Compact Composer controls in narrow layouts and keep native question and approval inputs separate from chat controls (BytePioneer-AI#624, BytePioneer-AI#625) - Support Codex Desktop 26.1023 native language settings (BytePioneer-AI#636) - Fix availability checks routed through the Harness Broker ### 新功能 - 会话导入支持选择本地或远程 Host，导入和打开始终使用所选机器；macOS 上通过 Broker 托管的 Claude Code、Cursor CLI、CodeBuddy 和 WorkBuddy 支持导入 (BytePioneer-AI#207) - 外部 Harness 多选问题使用公共卡片，可与单选、文本字段一起回答，切换聊天时保留未提交草稿 (BytePioneer-AI#625) - 接入 Grok 原生单选、多选和文本提问，支持取消及原生问题撤回 (BytePioneer-AI#625) - 从 Antigravity 原生历史记录统计请求和 Token，包括未经 codexhost 创建的 Session；原生记录缺少模型信息时显示为未知模型且不计价 (BytePioneer-AI#588) ### 修复 - Claude Code 后台 Subagent 运行期间支持同一 Turn 内继续插入指令，不必停止后台任务；已接受的指令保持归属当前 Turn (BytePioneer-AI#617) - Claude Code 子 Agent 消息被拒绝后正确释放 Turn；进入原生 worktree 后仍可 Fork 和进行消息编辑恢复 (BytePioneer-AI#626, BytePioneer-AI#629) - 改善 Pi 大历史 RPC 处理性能；只读查询超时后的迟到回复不再导致 Session 故障 (BytePioneer-AI#607) - Windows 上 PID 被其他进程复用时，可以回收残留的 Mapping Store 锁 (BytePioneer-AI#627) - 修复 Antigravity 多轮提问失效，明确项目工作目录，并限制进程清理等待时间 (BytePioneer-AI#586) - 避免把 Antigravity 整段 Conversation 的累计用量误当作当前上下文占用 (BytePioneer-AI#587) - Windows 和 macOS 上由 Host 启动的 Antigravity 进程默认关闭后台自更新，保留显式更新操作 (BytePioneer-AI#585) - ZCode 已登录但套餐或额度不可用时显示正确原因，不再要求重复登录 (BytePioneer-AI#621) - 窄布局下压缩 Composer 控件，并避免聊天控件干扰原生提问与审批输入 (BytePioneer-AI#624, BytePioneer-AI#625) - 适配 Codex Desktop 26.1023 的原生语言设置 (BytePioneer-AI#636) - 修复通过 Harness Broker 路由的可用性检查 ### Breaking Changes - Language overrides require Codex Desktop's native settings service. Desktops exposing only the legacy locale RPC are no longer supported for language overrides; reading can fall back to the browser language, but changing the override requires the native service (BytePioneer-AI#636) ### 破坏性变更 - 语言覆盖设置需要 Codex Desktop 原生 settings 服务。仅提供旧 locale RPC 的 Desktop 不再支持语言覆盖；读取时可以降级使用浏览器语言，但修改覆盖值需要原生服务 (BytePioneer-AI#636) ## Installation ### npm ```bash npm install -g @codexhost/cli codexhost ``` For remote Session import and multi-select questions, update the Desktop installation and the relevant remote Hosts and Brokers together. ### Installer Download the installer matching your OS and CPU architecture from this release's assets. ### macOS Gatekeeper After installing on macOS, if codexhost shows "Apple cannot verify this app" when you open it for the first time, run the following command in Terminal and reopen codexhost: ```bash xattr -dr com.apple.quarantine /Applications/codexhost.app ``` ## Contributors Thanks to everyone who contributed to this release: - @BeiLuoqu (BytePioneer-AI#585, BytePioneer-AI#586, BytePioneer-AI#587, BytePioneer-AI#588) - @bwndlct (BytePioneer-AI#617) - @BytePioneer-AI (BytePioneer-AI#207, BytePioneer-AI#625, BytePioneer-AI#626, BytePioneer-AI#627, BytePioneer-AI#629, BytePioneer-AI#636) - @cy2s (BytePioneer-AI#624) - @karlorz (BytePioneer-AI#625) - @kunkun9527 (BytePioneer-AI#607) - @SuperGoodGame (BytePioneer-AI#207) - @ump45nose (BytePioneer-AI#621) # Conflicts: # Cargo.lock # Cargo.toml # package-lock.json # package.json # packages/renderer-extension/src/renderer-binding-probe.ts

Summary
Antigravity 的上下文读数存在两个偏差：每个 Turn 结束时会变成整个会话的累计输入，并且随 Turn 增加越来越大；Turn 进行中如果命中提示词缓存，读数又会明显偏低。
原因有两个：
result事件里的 usage 是这个原生会话所有请求的合计，而hostUsage在没有显式上下文字段时会回退使用input_tokens。实测一个恢复的会话，4 次请求的input_tokens依次为 7,259 / 7,725 / 7,939 / 8,499，第 4 个 Turn 的result.usage.input_tokens是 31,422，正好是四者之和。于是上下文显示为 31,422，而最近一次请求的提示词只有 8,499。input_tokens不包含缓存读取，缓存部分单独记在cache_read_tokens。用本机 Antigravity CLI 1.4.6 的原生转录核对：下一次请求的cache_read_tokens约等于上一次请求的完整提示词（例如 7,284 + 0 之后紧接着是 2,717 + 7,285）。所以只看input_tokens时，命中缓存会让上下文被严重低估（例如显示 2,751，实际约 83,183）。改动只涉及 Adapter：
input_tokens + cache_read_tokens估算；显式的context_used_tokens/estimated_tokens_used仍然优先。GetCascadeTrajectoryGeneratorMetadata）时，仍用它覆盖估算值。本机 agy 1.4.6 上这个请求返回401 unauthenticated: missing CSRF token，所以实际显示的是步骤估算值。未包含：在状态栏标注“上下文（估算）”。现有的
HostUsage/ThreadUsageSnapshot合约没有表示上下文来源的字段，而按边界规则，Renderer 不应按 Harness ID 做分支。如果维护者认为需要这个标注，可以另开 PR 在合约里加一个可选字段。Related issues
N/A（#177 讨论过各 Adapter 的用量口径，已关闭）。
这是同一批 4 个 Antigravity 修复之一（#585、#586、#587、#588），各 PR 相互独立，可以单独合并；本地已验证 4 个分支一起合并没有冲突，测试通过。
