According to @bcherny, custom agents now support running subagents in dedicated Git worktrees by adding “isolation: worktree” in the agent frontmatter, enabling cleaner concurrent experiments and safer code generation workflows (as reported by the original tweet on X). For AI engineering teams, this supports sandboxed agent tasks, parallel feature development, and lower merge conflicts in agent-driven repos, according to the post by Boris Cherny. As reported by the tweet, the configuration targets multi-agent setups where LLM-powered subagents handle discrete branches, improving reproducibility, CI isolation, and rollback hygiene for AI-assisted coding pipelines.

According to Claude (@claudeai) on X, Claude Code on desktop now previews running apps, reviews code, and handles CI failures and PRs in the background; Boris Cherny (@bcherny) amplified the announcement with a demo link to the same post. As reported by Claude's official post, these capabilities target end-to-end developer workflows, from local app preview to continuous integration monitoring and pull request maintenance, reducing context switching and improving shipping velocity for AI-assisted software development. According to the same source, the background CI and PR handling suggests tighter integration with developer tools and repositories, opening opportunities for enterprises to standardize AI pair programming across teams and shorten review cycles.

According to @claudeai on Twitter, Claude now monitors pull requests by tracking CI in the background, attempting automatic fixes on failures and auto-merging once checks pass. As reported by the official Claude account, this enables hands-off CI remediation and just-in-time merging, reducing cycle time and context switching for engineering teams. According to the tweet, developers can move to their next task while Claude oversees the previous one, suggesting measurable gains in lead time for changes and deployment frequency for teams that integrate Claude with GitHub or GitLab CI pipelines.

According to Claude on X (Twitter), Anthropic’s Claude Code for desktop now supports live preview of running apps, automated code review, and background handling of CI failures and pull requests, as shown in the announced video post on February 20, 2026. According to Anthropic’s announcement on X, the live app preview lets developers inspect UI state while coding, which can shorten debug cycles and speed feature iteration for web and desktop apps. As reported by Claude’s official account, automated code review surfaces diffs with suggested fixes, enabling teams to standardize reviews and reduce manual toil in large repos. According to the same source, background CI failure triage and PR handling allow the agent to read logs, propose patches, and open or update PRs, which can cut mean time to repair in continuous integration pipelines and improve release velocity for startups and enterprise teams. For businesses, according to Claude’s post, these capabilities create opportunities to reduce review backlog, enforce coding conventions, and scale developer productivity across monorepos and microservices without expanding headcount.
