Claude Code Channels untether code review

Code review used to mean one tired engineer opening a pull request at 6:40 p.m. and scanning 400 changed lines with coffee-cold attention. Anthropic is pushing a different model: Claude Code can now run in the terminal, inside code editors, on desktop, in Slack, and even from the web, so review no longer has to live on one laptop screen. (anthropic.com) (claude.com) Claude Code itself is Anthropic’s coding agent, first announced on February 24, 2025 as a command-line tool that could read a codebase, make edits, run tests, and handle git workflows from natural-language prompts. Think of it less like autocomplete and more like handing a junior developer a ticket plus shell access. (anthropic.com 1) (anthropic.com 2) The recent shift is that Anthropic has been moving Claude Code onto more surfaces instead of keeping it trapped in a terminal window. On September 29, 2025, Anthropic added a native Visual Studio Code extension with inline diffs, and its current product page says the same extension works in Visual Studio Code forks like Cursor and Windsurf. (anthropic.com) (claude.com) That sounds cosmetic until you look at what review actually needs. A reviewer has to compare versions, inspect changed lines, keep a server running, and jump between comments, and Anthropic now describes Claude Code desktop as a place to manage parallel tasks, review visual diffs, preview servers, and monitor pull request status in one interface. (claude.com) Anthropic’s own language has also changed from “assistant” to “orchestrator.” Its September 2025 release introduced subagents, hooks, and background tasks, which means one Claude process can hand off a backend task to a specialist worker, trigger tests after edits, and keep long-running jobs alive while other work continues. (anthropic.com) That is the piece behind “channels,” even when Anthropic does not use that exact word on every page. Once coding work lives in a persistent shared space with task history, diffs, and automated checks, review starts to look less like a one-time approval and more like an ongoing thread where agents leave receipts. (anthropic.com) (claude.com) Anthropic is already shipping a concrete version of that idea in its Code Review plugin. The plugin says it runs five independent reviewers in parallel on a pull request, checking for bugs, project-rule compliance, git history context, earlier pull request comments, and whether code comments still match the code. (claude.com) It does not post everything it notices. Anthropic says each finding gets a confidence score from 0 to 100, and only high-confidence issues above the default threshold of 80 are posted, which is an attempt to cut the usual flood of noisy automated comments. (claude.com) Anthropic is also wiring this into the place teams already review code: GitHub. Its official Claude Code Action for GitHub pull requests and issues can answer questions, implement changes, and trigger on workflow context like an @claude mention or an issue assignment, which turns review from a static page into an event-driven system. (github.com) The company’s own webinar on “advanced patterns” makes the destination even clearer. Anthropic says teams are using subagents, hooks, and Model Context Protocol connections for automated pull request review, test generation, and catching regressions in continuous integration pipelines before a human reviewer sees them. (anthropic.com) There is also an enterprise reason this is moving off the desktop. Anthropic’s August 20, 2025 business-plan update added Claude Code seats for Team and Enterprise customers plus a Compliance Application Programming Interface for usage data, customer content access, auditing, and governance, which is what companies ask for when software work stops being a solo tool and becomes shared infrastructure. (anthropic.com) So the real story is not that Claude Code can open inside Cursor or Windsurf. It is that Anthropic is building the pieces for code review to happen in persistent, inspectable, multi-agent workflows where the human reviewer arrives later, sees the diffs, sees the test trail, sees the confidence-filtered comments, and decides with a lot more context than a single pass through a pull request.
