   OpenClaw Can Do WHAT NOW

   OpenClaw, a self-hosted open-source AI assistant that reached 350K GitHub stars in under 3 months, has spawned several community forks: ZeroClaw (built in Rust, 3.4MB, boots in 10ms), NanoClaw (under 4,000 lines, minimal dependencies, security-focused), and Maltis (enterprise-grade with audit trails). OpenClaw also introduced a 'dreaming' feature that consolidates memory in three phases mimicking human sleep — light sleep scans chats, REM identifies patterns, and deep sleep permanently stores only high-scoring memories recalled across multiple contexts. A community plugin extends this further by generating surreal narratives about your day.

   I use Claude Pro every day, and it has nothing to do with coding

   A tech journalist and designer shares how Claude Pro benefits non-developers. Key advantages include extended usage limits beyond the free tier's 5-hour reset, access to multiple models (notably Opus for research and reasoning), unlimited Projects with enhanced RAG-based knowledge management, and official Figma integration. The author uses Claude primarily for design iteration via Artifacts and research workflows, not coding, arguing that Claude Pro's value extends well beyond developer use cases.

   Baton: Orchestrate your AI coding agents

   Baton is a desktop app for orchestrating multiple AI coding agents in parallel. Each agent runs in its own git-isolated workspace, with smart notification badges to flag which agents need attention. It supports Claude Code, Codex, OpenCode, and any terminal-based agent. Features include diff review, file browsing, codebase search, and a built-in MCP server that lets agents spawn new agents. Built by a developer who needed a single unified interface to manage multiple agents without constant window-switching.

   CMUX: Too Much Hype?

   A hands-on critical review of CMUX (Simax), a new Mac-only terminal multiplexer built on top of Ghostty, aimed at AI agent workflows. The reviewer explores its workspace management, embedded browser tabs, notification system, CLI API, and SSH features, comparing them extensively to tmux with plugins like Sesh and Session X. While acknowledging CMUX has unique features (embedded browser, agent notifications, scriptable API), the reviewer finds it too rough around the edges, Mac-only, and not compelling for experienced tmux or Ghostty power users. The conclusion is that CMUX may appeal to newer developers forced into the terminal by AI agents, but doesn't justify the hype for seasoned terminal users.

    Agent React DevTools: Debug React Apps with AI Agents

    Callstack has released Agent React DevTools, a CLI that gives AI agents direct access to React DevTools internals — including the component tree, state, profiling data, renders, and performance hotspots. Unlike UI tree inspection alone, this enables AI agents to understand why an app behaves a certain way, not just what it looks like. It integrates as a skill for AI agents and supports React and React Native apps. Integration with third-party plugins via Rozenite is also available, with plans to unify both into a single CLI.

    I think every company should open source their code.

    A strong argument for why companies should open source their software, framed around the emerging 'building block economy.' The core thesis is that AI agents prefer open, modular, well-documented components over closed commercial software, and that the future of competitive advantage lies in letting customers fork and customize your product rather than building every feature yourself. Uses T3 Code's 1,500 forks and Mitchell Hashimoto's Ghosty/libghosty growth data as evidence. Also introduces the concept of a 'patch.md' file — a plain-English description of user customizations that enables AI-assisted merge conflict resolution when upstream updates break forks — as a path toward self-forking, self-healing software.

    GitHub Changelog·4w

    Copilot CLI activity now included in usage metrics totals and feature breakdowns

    GitHub Copilot's CLI activity is now integrated into the top-level usage metrics totals and dimensional breakdowns in the Copilot usage metrics API. Previously, CLI metrics were reported separately in a standalone `totals_by_cli` section, leaving top-level totals reflecting IDE activity only. Now fields like `code_generation_activity_count`, `code_acceptance_activity_count`, and `loc_added_sum` combine IDE and CLI data. CLI also appears as `feature=copilot_cli` in feature, model, and language breakdowns. Admins should note that top-level totals have changed meaning and may see higher numbers if their dashboards assumed IDE-only values.

    How much of your code is written by agents? - Buildermark (Open Source)

    Buildermark is an open source tool that measures how much of your codebase is written by AI coding agents. It works by matching agent diffs with git commits to calculate the percentage of AI-generated code. It also archives all conversations from agents like Claude Code, Codex, Gemini, and Cursor. A live demo shows 364 agent conversations that produced 94% of Buildermark's own code.

    Speeding up interactive rebase in JetBrains IDEs

    JetBrains engineers implemented an in-memory interactive rebase optimization for JetBrains IDEs, reducing execution time from tens of seconds to a few seconds on large repositories like the IntelliJ monorepo. Instead of checking out commits sequentially and updating the working tree and index, the IDE now uses Git plumbing commands (git cat-file, git commit-tree, git merge-tree, git update-ref) to rebuild commit chains entirely in memory. If a merge conflict is detected, it falls back to the standard Git rebase. The optimization covers reword, drop, squash, and extract-to-separate-commit operations. EAP telemetry confirmed consistent improvements across macOS, Windows, and Linux, with ~12% of rebases encountering conflicts that trigger the fallback. The feature ships by default in the 2026.1 release.

    HIPPO is a storeless password manager that derives site passwords on the fly using cryptography

    HIPPO is a research-stage browser extension that eliminates password storage entirely by deriving site-specific passwords on the fly. It uses an Oblivious Pseudorandom Function (OPRF) protocol: the extension blinds your master passphrase and sends it to a server, which processes it with its own secret key — neither side sees the other's raw secret. The result is a deterministic, high-entropy password per site that gets auto-filled. A 25-person user study found HIPPO scored higher on perceived security and trust compared to manual password entry. Key tradeoffs include server dependency as a single point of failure, no 2FA support, and unresolved master password change and account lockout scenarios. HIPPO remains a research concept with no live deployment yet.
