Grok Build’s /goal Mode Is xAI’s Agent Handoff Primitive — and Its Next Safety Test

Grok Build’s /goal Mode Is xAI’s Agent Handoff Primitive — and Its Next Safety Test

xAI’s new /goal mode for Grok Build looks small if you squint: one more slash command in a terminal coding agent. That is the wrong read. The interesting part is not the syntax. It is the contract change. Grok Build is no longer only asking developers to supervise a

Claude Code 2.1.185 Turns a Retry Message Into a Production-Signal Problem

Claude Code 2.1.185 Turns a Retry Message Into a Production-Signal Problem

Sometimes the smallest changelog item is the one that tells you where the product is hurting. Claude Code 2.1.185 shipped with one public note: the stream-stall message now says “Waiting for API response · will retry in …” instead of “No response from API · Retrying in …”, and the hint appears

OpenClaw’s Hub-Delegated ACP Workers Make Multi-Agent Orchestration Less Thread-Shaped

OpenClaw’s ACP delegation work is easy to describe badly: “persistent external harness sessions without threads.” Accurate, but too small. The more interesting point is that PR #91093 admits something most multi-agent products still pretend is not true: the thread is a UI affordance, not an orchestration primitive. Discord and

Qwen Code 0.18.1 Preview Fixes the Fork/Subagent Trap and Makes Token Waste Visible

Qwen Code 0.18.1 Preview Fixes the Fork/Subagent Trap and Makes Token Waste Visible

Qwen Code shipped a preview release this week, and if you only read the version number you would assume it is a minor patch. The 0.18.1-preview.0 changelog is anything but minor. It is a course correction to one of the most muddled concepts in agent orchestration: what

SpaceX Buying Cursor Is the Clearest Sign Yet That Grok Build Is Not Just a Side Quest

SpaceX Buying Cursor Is the Clearest Sign Yet That Grok Build Is Not Just a Side Quest

SpaceX buying Cursor for an implied $60 billion is easy to misread as another entry in the Elon Musk mega-deal ledger. The more useful read is narrower and more important for developers: xAI is buying the workflow layer Grok Build does not yet own. The June 16 SEC filing says

OpenClaw’s Kiro ACP Retry Fix Shows Why Multi-Agent Platforms Need Error Taxonomy, Not Hope

OpenClaw’s Kiro ACP Retry Fix Shows Why Multi-Agent Platforms Need Error Taxonomy, Not Hope

OpenClaw PR #93642 is a one-line regex-sized fix with a platform-sized lesson: multi-agent systems do not become reliable just because everyone agrees to speak the same protocol. Eventually a backend says “Internal error,” the thread keeps looking alive, and the orchestrator has to know whether that means “retry safely” or

Qwen Code 0.18.1 Preview Fixes the Fork/Subagent Trap and Makes Token Waste Visible

Qwen Code’s latest preview is a reminder that “parallel agents” is not an architecture. It is a marketing phrase until the runtime can answer the boring questions: does the child return a result, does it inherit context, does it share the prompt cache, does it isolate filesystem work, and
