Story

Cline's CLI shipped a fix disclosing checkpoints were never recorded at all due to a run-boundary regression, so /undo failed once the agent used tools. Run a throwaway task, let the agent modify files, then attempt a restore. If your safety net is untested, it's a belief rather than a control.

Cline's Open-Source SDK Outscores Claude Code on the Same Model. The Agent Lock-In Myth Is Over.
Cline released @cline/sdk on May 13, an open-source TypeScript agent runtime that powers their CLI, VS Code, and JetBrains extensions. Running claude-opus-4.7, Cline CLI scores 74.2% on Terminal-Bench 2.0. Claude Code on the same model: 69.4%. Same model. Different harness. Al...
Open Design turns 25+ agent CLIs into a design engine with one MCP install command.
v0.10.0 (~84.8k stars, Apache-2.0) ships no agent of its own and drives whichever CLI you already have, Claude Code, Codex, Cursor, Copilot, OpenClaw, Gemini, Kimi, Qwen, Cline, plus BYOK OpenAI-compatible endpoints, via od mcp install <agent>. It produces single-page HTML pro...
Cursor 3 Ditches VS Code for Agent Orchestration. Claude Code Holds 54% Market Share at $1.2B ARR.
The IDE market is fragmenting, and this week drew the sharpest lines yet. Cursor 3 launched as a rebuilt agent-orchestration platform in Rust and TypeScript, replacing the VS Code fork with an Agents Window for dispatching and monitoring multiple AI coding agents. Anysphere hi...
Y Combinator open-sources QM, the harness running its company
QM went up under MIT license. Created July 29. As of the GitHub API check: 8,420 stars, 887 forks. Five days. YC uses it internally across accounting, legal, events, and engineering, including to build QM itself. Every employee and every Slack room gets its own scoped memory,...
Three independent projects now ship multi-harness agent control surfaces: AionUi at 31,747 stars, t3code at 17,477, agent-of-empires at 3,022.
A category has formed around one job, watching and steering many concurrent coding agents from a single pane. AionUi (TypeScript) markets a 24/7 "Cowork" app spanning OpenClaw, Hermes, Claude Code, Codex, OpenCode and 20+ more CLI agents; agent-of-empires (Rust) offers TUI and...
The config file is the new attack surface, across every IDE.
The Amazon Q bug is one instance of a 2026 pattern: MCP configuration carried in repositories is now an RCE supply-chain vector, not just untrusted tool output. Cursor, VS Code, Windsurf, Claude Code, and Gemini-CLI are all vulnerable to MCP-based auto-launch attacks (Windsurf...
