A deep dive into kbd-1.0 Codex Micro, OpenAI's first branded hardware (July 15, 2026): a $230, 13-key macro pad built with Work Louder featuring agent-status RGB, a joystick for Codex skills, and a reasoning-level dial — plus the skepticism about adding buttons to a natural-language workflow.

**[Mosaic (mosaic.inc)](https://mosaic.inc/) is a desktop tool that runs multiple AI coding agents ([Claude Code](https://claude.com/product/claude-code) / Codex / OpenCode) in parallel from a single UI**, and on top of that offers **"SHARED CONTROL" — a rare feature in 2026 that lets multiple people live-edit a single Claude Code session together**. **The core of SHARED CONTROL**: spin up a session, a teammate joins the same terminal, and **you both see each others cursors, prompts, and output in real time** — genuinely shared control, not screen-share theater. The experience of Google Docs or VS Code Live Share, applied to a Claude Code session. Use cases (see the standing [request in Anthropic issue #60082](https://github.com/anthropics/claude-code/issues/60082)): pair programming, team debugging, onboarding, live review, and division of labor (Ali refactors the auth middleware while Shubham adds the rate-limit test — same session). **Parallel-ops layer**: each agent gets a **Git-worktree-isolated workspace**, and 5-10 agents can develop different branches / features concurrently with zero file collisions or state interference. **Position**: in the rapidly maturing late-2026 parallel-Claude-Code market, Mosaic competes with **[Conductor](https://www.ycombinator.com/companies/conductor) (YC, Mac-native)**, **[Superset](https://superset.sh/) (three ex-YC CTOs, 10+ concurrent)**, **[Herdr](../columns/herdr-terminal-agent-multiplexer-2026-07) (terminal-native, Rust)**, and Product-Hunt entries like [Claudy](https://www.producthunt.com/products/claudy) / [Multi-Claude](https://www.producthunt.com/products/multi-claude) — its distinctive differentiation is **real-time SHARED CONTROL**. Target users: solo developers, startup CTOs, staff engineers, plus **teams that want pair programming and live review with AI agents in the loop**. Combined with [Command Code taste-1 learning](../columns/commandcode-taste-1-personalized-coding-agent-2026-07), [the grill-me skill](../columns/grill-me-agent-skill-2026-07), and [Crit.md HITL review](../columns/crit-md-local-first-agent-review-2026-07), it forms a **"parallel × personalized × thoroughly reviewed × real-time collaborative" late-2026 AI dev stack**.

**[Herdr](https://herdr.dev/) is a terminal-based AI agent multiplexer** — run multiple AI coding agents ([Claude Code](https://claude.com/product/claude-code) / OpenCode / Codex, etc.) in parallel from **a single terminal**, with sessions **persisted server-side** (like tmux) so you can reattach from any device. **Key features**: (1) **multi-agent orchestration** — run multiple agents in independent panes, (2) **persistent sessions** — agents keep running after terminal detach, reattach from anywhere, (3) **SSH-friendly remote access** — like tmux but agent-aware, (4) **real terminal panes** — clickable layouts and mouse support, (5) **at-a-glance agent state** (blocked / working / done / idle), (6) a **Control API** (CLI + JSON socket) for programmatic session management, (7) a **mobile-friendly UI** for terminal access from phones and tablets. Ships as a **Rust binary** (not Electron) with no external dependencies. Target audience: **engineers at JetBrains / Docker / Vercel / Google / NVIDIA / AWS**. Position: paired with [Crit.md's HITL review substrate](../columns/crit-md-local-first-agent-review-2026-07), Herdr is the **"agent-operations infrastructure"** side of the coin — solving the execution environment rather than the review loop. Part of the broader "day-to-day AI-agent tooling" trend alongside our [Cloudflare-only stack](../columns/cloudflare-only-stack-viral-2026-07) and [Claude Cowork web/mobile](../columns/claude-cowork-web-mobile-launch-2026-07) coverage.

cmux by Manaflow (YC S24) is a macOS-native terminal built specifically for running multiple AI agents in parallel. Powered by Ghostty's libghostty in Swift/AppKit, it offers vertical tabs, notification rings, an embedded browser, and a socket API. This column covers its features, install, use cases, competitive landscape, and considerations for enterprise adoption in Japan.

On June 2, 2026, OpenAI added a 'Sites' feature to Codex. Users can generate web apps, dashboards, and games inside Codex and instantly share an OpenAI-hosted URL within their workspace. The supported runtime is limited to Cloudflare Worker-compatible ES Modules, and the feature is currently available as a preview for Business and Enterprise plans only. There is no staging environment, and no official statement on public (anonymous) access. While ideal for internal PoC and departmental dashboards, it is too early to adopt as a foundation for customer-facing production services. The unusual structure of Vercel, Replit, and Lovable being both competitors and partners is drawing attention.

On May 29, 2026, OpenAI's Codex desktop app v26.527 brought **Computer Use (Codex driving any app by seeing, clicking, and typing on the screen) to Windows** for the first time — previously macOS-only. This column reads the official Changelog and Codex Computer Use docs as primary sources to cover the Windows-specific foreground-only execution constraint (unlike macOS's parallel background mode), the OS-level PowerShell sandbox, install via Microsoft Store and `winget`, the regional rollout excluding the EEA / UK / Switzerland at launch (**Japan is included**), pricing, comparisons with Anthropic Claude Computer Use, Claude Code, Cursor, and UiPath, and what this means for Japanese enterprises where Windows 11 dominates office endpoints.

OpenAI's Symphony, released in 2026 as an open-source spec, defines a "ticket-driven AI development" pattern: each Linear issue gets its own Codex agent in its own workspace and runs until the issue reaches a terminal state. This article walks through the spec's core ideas, the Elixir reference implementation, the polling / supervisor / workspace-isolation architecture, and the realistic operational considerations for adopting it — based on publicly available information.

Summary of OpenAI's GPT-5.5 released on April 23, 2026: improvements in coding, computer use, online research, and document/spreadsheet creation; rollout to ChatGPT Plus/Pro/Business/Enterprise and Codex; API availability; and safety updates — all based on official information.
