时代变了，过去那么多的规则、约束、文档，感觉现在只会让模型的推理效率和效果变得越来越垃圾，Anthropic说的确实对。 今天决定直接大幅重构所有的文档和规则，清空重写。。。 从此思路不再是用规则约束模型指望它一次写对，而是在前期交给模型更多的思考空间更多的注意力，把更多的限制，加在测试侧，用测试来限制一切。 文档和规则，真的要退环境了。

We removed ~80% of the Claude Code system prompt for our newest models, this is what we've learned about writing system prompts, skills and Claude.MDs for them. http://x.com/i/article/2080703729385512960

Grok Build new update brings a guided /tutorial tour, smarter search tool overrides, live workflow progress with one-click failed-run resume, and a wide reliability pass across workflows, voice, and tools Release Notes: v0.2.112 Breaking Changes: • CLI version policy now has separate soft update floors/ceilings and hard startup requirements Features: • New /tutorial slash command opens an opt-in nine-topic onboarding tour of Grok. • New tool_overrides option lets you set date cutoffs and domain allowlists for the agent's built-in search tools. • New toolOverrides option lets you set date cutoffs and domain allowlists for the agent's built-in search tools. • New config options let you add query parameters or environment-backed headers to custom model providers and control which variables reach shell tools. • Terminal and environment fixes are now consolidated under the /doctor command with clearer guidance. • Marketplace add now rejects non-git URLs at add time instead of failing later. • Slash commands can now show optional bracket tags (e.g. [new]) via config or remote settings. • Queued prompts now offer an [edit] mouse button alongside Send now and cancel. • Voice shortcut toggle in settings can disable the Ctrl+Space/F8 keybind without disabling voice entirely. • Image edit can now use a remotely configured model slug instead of the hardcoded default. • `grok doctor fix` can now repair common tmux clipboard and passthrough problems. • Per-provider auth helpers now work on Windows and can run from a configurable working directory. • /resume now shows only native Grok sessions by default and shows a hint when external sessions are hidden. • `grok --resume` can now resume a session by its title as well as by ID. • Workflows overlay now shows live per-agent progress and automatically follows the active phase. • Workflow runs that failed can now be resumed; scratch file limits were also increased. • Hooks can now be defined in config.toml in addition to JSON files. • Clicking the "still running" status now opens the tasks pane. Bug Fixes: • File attachments now appear correctly when resuming or replaying conversations. • Terminal output from remote clients is now recorded so read-file hints and monitors function correctly. • Background shell commands now correctly report their real exit codes instead of always showing -1. • Marketplace source refreshes no longer hang the TUI or trap you in the extensions modal. • Background task tray now correctly clears killed tasks and keeps task descriptions after reconnect. • Dashboard overlay now correctly returns after forking a dashboard-attached session. • Linux voice dictation now works on PipeWire versions before 1.6. • Fork from a rewound session now copies the correct live-branch history. • Account pane now shows name and email even after the access token expires. • Voice mode now lets you edit already-dictated text without closing the microphone. • Fixed startup hangs on Linux after concurrent launches or rapid restarts. • MCP tools now appear without restart after enrolling or updating a managed service. • Plugin subagents now see the same MCP tools as the parent session. • Copy confirmations now show shorter messages when the clipboard succeeds. • Repeated identical tool calls now end the turn silently instead of showing a stop banner. • Web search now defaults to grok-4.5. • Voice dictation text is no longer dropped when pressing Enter to send. • Bash mode (`!`) now shows yellow prefix and action label in minimal mode. • Parked turns no longer spam duplicate "Worked for" markers in the transcript.

Anthropic launched Claude Opus 5 at half the price of its most powerful model Fable 5, while at the same time beating Feble 5 in almost all benchmarks. Costs the same as Opus 4.8, $5/$25 per mn input/ output tokens, but exactly half as much as Fable 5. Frankly I am trying to figure out at this price of Opus 5 and with this great benchmark result why would I ever need to use Fable 5. Opus 5 also has less restrictive cyber classifiers than Fable, automatic fallback options, mid-conversation tool changes and no special data-retention requirement for general access. The cheaper model is winning specifically on economically valuable activities—coding, operating computers, research and completing business processes—not merely trivia or academic question answering. Anthropic repeatedly describes Opus 5 as more willing to verify, recover and continue until a task is actually complete. Examples include: - Creating its own computer-vision pipeline to reconstruct a 3D machine component from raw pixels - Finding the root cause of an open-source bug and fixing an edge case missed by the existing community patch - Building a market-data integration and then creating its own test harness when no live validation feed was available - Completing Zapier’s full churn-prevention workflow when previous models failed These are signs of adaptive problem-solving: the model notices that a required capability or validation mechanism is missing and constructs one instead of stopping. Anthropic also describes Opus 5 as more thorough about validating its work and recovering when necessary. The launch gives examples in which it constructed its own vision pipeline, identified the underlying cause of a software bug and built a test harness when no live data feed existed. That is potentially more commercially meaningful than a modest benchmark gain. An agent that finishes 70% of jobs without intervention can be dramatically more valuable than one that produces slightly better individual responses but frequently stalls.
