/ultrareview research preview
Now in public research preview. Ultrareview runs a fleet of bug-hunting agents in the cloud against your branch or a PR, and findings land back in the CLI or Desktop automatically. Run it before merging critical changes such as auth or data migrations.
Review the branch you're on:
> /ultrareview
Or point it at a PR:
> /ultrareview 1234
Session recap CLI
Switch focus away from a session and come back to a one-line recap of what happened while you were gone. Helpful for staying in flow while running several Claude sessions at once.
Generate a recap on demand, or turn the automatic one off from /config:
> /recap
Interactive mode: session recap
Custom themes v2.1.118
Build and switch between named color themes from /theme, or hand-edit JSON files in ~/.claude/themes/. Each theme picks a base preset and overrides only the tokens you care about. Plugins can ship themes too.
Open the theme picker and create a new one:
> /theme
Terminal config: create a custom theme
Claude Code on the web web
A new look for claude.ai/code that matches the redesigned desktop app: sessions sidebar, drag-and-drop layout, and a refreshed routines view. Key parts were rebuilt for quicker responses and a more reliable experience.
Other wins
Vim visual mode: press v for character selection or V for line selection in the prompt input, with operators and visual feedbackHooks can now call MCP tools directly via type: "mcp_tool", so a hook can hit an already-connected server without spawning a process/cost and /stats are merged into /usage; the old names still work as typing shortcuts that open the relevant tab/config changes (theme, editor mode, verbose, and similar) now persist to ~/.claude/settings.json and follow the same project/local/policy precedence as other settingsForked subagents can be enabled on external builds with CLAUDE_CODE_FORK_SUBAGENT=1: a fork inherits your full conversation context instead of starting freshDefault effort level for Pro and Max subscribers on Opus 4.6 and Sonnet 4.6 is now high (was medium)Native macOS and Linux builds replace the Glob and Grep tools with embedded bfs and ugrep available through Bash, for faster searches without a separate tool round-trip--from-pr now accepts GitLab merge request, Bitbucket pull request, and GitHub Enterprise PR URLs in addition to github.comAuto mode: include "$defaults" in autoMode.allow, soft_deny, or environment to add custom rules alongside the built-in list instead of replacing itNew claude plugin tag command creates release git tags for plugins with version validationOpus 4.7 sessions now compute against the model's native 1M context window, fixing inflated /context percentages and premature autocompaction/resume on large sessions is up to 67% faster and now offers to summarize stale, large sessions before re-reading them
