BREAKING: SpaceXAI has released a new and improved update for Grok Build. v1.0.12 — 2026-08-27 Performance: • Worktree creation is faster by skipping stale reflog copies. Bug Fixes: • Copying wrapped table cells no longer inserts unwanted spaces at line breaks. • MCP server connections that fail transiently now retry instead of staying unavailable. • Waiting on subagents after an interjection no longer blocks on unrelated background work. • Prompt blocks now show friendly hook descriptions instead of internal IDs. • Truncation error message no longer suggests asking for a shorter answer. • Context estimates for conversations with reasoning are now more accurate. • Token usage after rewinding or switching modes now matches the actual server-reported count instead of overestimating. • Context bar now updates immediately when auto-compaction begins instead of waiting until it finishes. • File system monitoring for .NET projects no longer creates excessive watchers on Linux. • Auto recap no longer appears while a background task or monitor wake turn is streaming.

Claude Code 会话价值最大化指南 -- 适用于你的 Coding Agents：从缓存、上下文到 Subagent 的成本优化 先看两个问题： 1. 单个 token 的价格由什么决定 2. 一个会话会发出多少 token # Token 单价的三个决定因素 1. 模型 更大的模型对输入、输出都做更多计算。难题/模糊任务用大模型，常规任务用小模型——其余所有优化都会被模型单价放大。 2. 输入 vs 输出 · Prefill：系统提示、CLAUDE.md、你的消息、以及会话中累积的所有内容（读过的文件、命令输出）。 · Decode：思考、工具调用、回复文本。逐 token 串行生成，GPU 占用时间更长，因此输出价格约为输入的 5 倍。 · 输出中很大比例是 thinking token，其数量由 /effort 控制。已知是体力活的会话，可用 MAX_THINKING_TOKENS=0 直接关闭思考。 3. 提示词缓存 · 机制：请求前缀与上次完全相同，则前缀部分直接读取缓存状态，只对新增部分全价 prefill。 · 价格：缓存读取 0.1×，缓存写入最高 2×（写入只发生一次，之后每轮都是 0.1× 读取）。 · Claude Code 自动管理缓存，但以下行为会击穿缓存，导致整个会话重新全价 prefill： · /model 切换模型（含 opusplan 进出 plan 模式） · /effort 切换思考档位 · 开启 Fast mode（且按 fast 价格重新 prefill） · /compact 压缩会话（系统提示部分保留） · 时间过期：订阅 1 小时、API key 5 分钟（ENABLE_PROMPT_CACHING_1H=1 可延长到 1 小时）；恢复旧会话基本必然 miss 结论：不是不能切换，是要选便宜的时机——会话开始时或 /clear 之后，而不是长对话中途。 # 会话 Token 量的成本模型 关键事实：进入上下文的任何内容（读过的文件、命令输出），会在之后的每一轮被重新发送，直到会话结束。虽然有缓存折扣，但便宜不等于免费，还占用模型每轮要"绕着思考"的上下文空间。 1. 什么进入了上下文 · 启动即加载：工具定义、系统提示、CLAUDE.md、MCP 工具定义。用 /context 审计；CLAUDE.md 只留通用指令，流程性内容移到 skills；用不到的 MCP 用 /mcp 关掉。 · 探索成本：说"测试挂了"，Claude 要先 grep、开一堆文件去定位，这些中间结果会留在上下文里。直接说"修 utils.test.ts 里挂掉的测试"省掉搜索；用 @ 提及文件连 Read 调用都省了（文件随第一条消息直接附上，且一次会话只需提及一次）。 · 命令输出：超过 3 万字符会自动落盘只留摘要（BASH_MAX_OUTPUT_LENGTH 可调），真正的杀手是阈值以下的中等输出——比如 400 行逐行打印的通过测试。对策：给命令加 quiet flag、用 subagent、或用 hook 改写嘈杂命令；把高频命令连同静默参数写进 CLAUDE.md。 2. 在上下文里停留多少轮 · 一个长会话比拆成几个短会话贵，且贵得超乎直觉——第 40 轮要重读前 39 轮。 · 任务切换用 /clear，同一任务前半段完成用 /compact；/clear 前可先 /rename 以便找回；/compact 时告诉它保留什么。 · 一个反直觉的省钱技巧：如果最近几轮走偏了，用 /rewind 回滚而不是 /compact——rewind 只砍掉尾部，前缀缓存仍在，成本为零。 · 注意"你不在打字时发生的轮次"：/loop 每次都携带整个会话触发完整一轮，超 1 小时还叠加缓存失效——应在新终端的干净会话里跑。 3. Subagents：隔离上下文的另一手段 · 子 agent 有独立上下文（含系统提示、工具、CLAUDE.md），但不带你的对话；只有最终结论返回主会话，其余全部丢弃。 · 代价是可能要重读主会话已读过的内容，小任务不划算；适合"产出大量你不需要保留的输出"的任务（如翻日志）。 · 固定外包的嘈杂任务，给它定义一个用 haiku/sonnet 的专属 subagent，否则它默认跑在主会话的模型上。 # 可执行清单（按性价比排序） 1. 任务之间 /clear —— 阻断无关上下文持续计费 2. 开工前定好 /model 和 /effort —— 中途切换击穿缓存 3. @ 提及文件代替写路径 —— 省掉 Read 调用和搜索 4. 嘈杂命令加静默 flag 或丢给 subagent —— 命令输出会驻留整个会话 5. 新会话先跑 /context —— 审计启动加载项，砍掉不需要的 6. 离开键盘前 /compact —— 缓存 1 小时过期，趁热压缩便宜得多

Tomorrow is the total solar eclipse 🌑☀️ Whether you’re in the path of totality across Greenland, Iceland, and Spain, or watching the partial phases online, we’ve got you covered. The interactive 3D visualizer built in @GoogleAIStudio lets you follow the Moon's shadow across the globe in real-time, simulate local sky views from stations like Reykjavík or Valencia, and fast-forward or rewind to catch key eclipse milestones:

🚨 NEW GROK BUILD UPDATE 🚨 v1.0.1 — 2026-08-10 Updates: • /rewind now only truncates conversation history instead of files as well and asks for confirmation by default. • Managed MCP servers are now only available through the gateway catalog. Features: • Subagent spawning is now bounded; wide fan-outs queue instead of exhausting file descriptors. • New grok du command shows disk usage of ~/.grok including worktrees and sessions. • Tools now report whether they only read data, enabling safer restricted agents and subagents. • Sandbox workspace sessions can now limit which bundled skills are advertised via caller config. • Renaming a session from the dashboard now starts with the current title prefilled for easy editing. • /usage, /session-info, and /context now open in a tabbed modal instead of adding text to the conversation. • grok trace exports now bundle memory trace files for easier debugging. • Session rename now enforces a 100-character limit, ghost-prefills the current title, and preserves manual titles across machines. • New /rename --auto command unpins a manual session title so automatic titling resumes. • Video generation from references now supports preset voices, single-image input, 1–15 s durations, and 4:3 / 3:4 aspect ratios. Bug Fixes: • Sandbox config entries ending in /** now correctly grant the parent directory instead of creating a literal ** subdirectory. • Failed alpha/enterprise updates now suggest the matching GROK_CHANNEL reinstall command. • On Apple Silicon, grok now installs the native arm64 build even from a Rosetta shell or x86_64 updater. • Skills that share names with built-in commands now appear alongside them in the slash menu with qualified names. • Notebook permission rules imported from Claude configs are now ignored with a warning instead of applying broadly. • Goal evaluation at round end no longer fails due to timeouts. • Tool timeouts no longer cause the agent to hang when child processes are stuck in D-state or hold pipes open. • Home and End keys now move to the start or end of the current logical line even when the prompt is wrapped. • Worktree sessions now correctly show their branch in the status bar. • Worktree sessions now keep their status correctly when switching directories or resuming. • Worktree status is no longer lost when opening the dashboard. • Recaps are now written in the same language as your conversation. • Plugin suggestions no longer flash incorrectly while typing. • Send Now now works during active goals without cancelling the goal. • Headless sessions now correctly wait for MCP servers when using delivery tools. • Non-interactive sessions (grok -p) no longer fail when the agent asks for user input or plan approval. • read_file errors for missing skills now suggest the correct registered path instead of a generic hint. • Session load and creation can no longer freeze forever when .envrc evaluation blocks. • Upgraded installs no longer silently run outdated platform skill instructions. • Deleting a session now properly stops and waits for any running subagents before wiping history. • Permission and plan-approval notification hooks no longer fire on auto-allowed tools. • Mid-turn steering sent with double-Enter or Ctrl+Enter now correctly tells the model it arrived while work was in progress. • Scrollback drag selection no longer gets stuck after the mouse button is released outside VS Code or Cursor terminals. • Video generation tools now show a clear error explaining ZDR storage requirements instead of silently disappearing. • Esc on the cancel-turn panel now closes the panel and keeps the current turn running as the shortcuts bar indicates.

好，总结起来，6个每天必用的命令，1个提升43%的自定义命令，再加2个彩蛋。 大家发现没有，它们干的其实是同一件事，就是开头说的那句：把Claude当成一个真同事来带。 专注，交给clear 不打扰，交给btw 状态，看statusline 方案，先过plan 后悔了，有rewind和resume 验收，有goal 那需求沟通，就交给你自己造的那个命令。 内置命令还有二三十个，大家也可以自己去翻一翻，找到顺手的，或者更进一步，直接造你自己的。
