この更新の概要
新機能「Ultraplan」のプレビュー版が公開され、ターミナルからクラウド上で計画を策定しブラウザでレビュー可能になりました。背景タスクを監視してイベントを会話に流し込む「Monitor」ツールや、チーム向けセットアップガイドを生成する「/team-onboarding」コマンドなどが追加されています。Bashツールの実行権限ルールが強化され、コマンドセパレータやプロセスラッパーの扱いがより詳細に定義されました。Windows環境でのインストールトラブルや32bit非対応に関するトラブルシューティング情報も拡充されています。

The permission dialog writes the `:*` form when you select "Yes, don't ask again" for a command prefix. This form is only recognized at the end of a pattern. In a pattern like `Bash(git:* push)`, the colon is treated as a literal character and won't match git commands.
## Tool-specific permission rules
@@ -114,14 +116,26 @@ Bash permission rules support wildcard matching with `*`. Wildcards can appear a
- `Bash(npm run test *)` matches Bash commands starting with `npm run test`
- `Bash(npm *)` matches any command starting with `npm `
- `Bash(* install)` matches any command ending with ` install`
- `Bash(git * main)` matches commands like `git checkout main`, `git merge main`
- `Bash(git * main)` matches commands like `git checkout main` and `git log --oneline main`
A single `*` matches any sequence of characters including spaces, so one wildcard can span multiple arguments. `Bash(git:*)` matches `git log --oneline --all`, and `Bash(git * main)` matches `git push origin main` as well as `git merge main`.
When `*` appears at the end with a space before it (like `Bash(ls *)`), it enforces a word boundary, requiring the prefix to be followed by a space or end-of-string. For example, `Bash(ls *)` matches `ls -la` but not `lsof`. In contrast, `Bash(ls*)` without a space matches both `ls -la` and `lsof` because there's no word boundary constraint.
Claude Code is aware of shell operators (like `&&`) so a prefix match rule like `Bash(safe-cmd *)` won't give it permission to run the command `safe-cmd && other-cmd`.
#### Compound commands
Claude Code is aware of shell operators, so a rule like `Bash(safe-cmd *)` won't give it permission to run the command `safe-cmd && other-cmd`. The recognized command separators are `&&`, `||`, `;`, `|`, `|&`, `&`, and newlines. A rule must match each subcommand independently.
When you approve a compound command with "Yes, don't ask again", Claude Code saves a separate rule for each subcommand that requires approval, rather than a single rule for the full compound string. For example, approving `git status && npm test` saves a rule for `npm test`, so future `npm test` invocations are recognized regardless of what precedes the `&&`. Subcommands like `cd` into a subdirectory generate their own Read rule for that path. Up to 5 rules may be saved for a single compound command.
#### Process wrappers
Before matching Bash rules, Claude Code strips a fixed set of process wrappers so a rule like `Bash(npm test *)` also matches `timeout 30 npm test`. The recognized wrappers are `timeout`, `time`, `nice`, `nohup`, and `stdbuf`.
Bare `xargs` is also stripped, so `Bash(grep *)` matches `xargs grep pattern`. Stripping applies only when `xargs` has no flags: an invocation like `xargs -n1 grep pattern` is matched as an `xargs` command, so rules written for the inner command do not cover it.
This wrapper list is built in and is not configurable. Development environment runners such as `direnv exec`, `devbox run`, `mise exec`, `npx`, and `docker exec` are not in the list. Because these tools execute their arguments as a command, a rule like `Bash(devbox run *)` matches whatever comes after `run`, including `devbox run rm -rf .`. To approve work inside an environment runner, write a specific rule that includes both the runner and the inner command, such as `Bash(devbox run npm test)`. Add one rule per inner command you want to allow.
Bash permission patterns that try to constrain command arguments are fragile. For example, `Bash(curl http://github.com/ *)` intends to restrict curl to GitHub URLs, but won't match variations like:
- Options before URL: `curl -X GET http://github.com/...`

# Week 15 · April 6–10, 2026
> Ultraplan cloud planning, the Monitor tool with self-pacing /loop, /team-onboarding for packaging your setup, and /autofix-pr from your terminal.
Releases v2.1.92 → v2.1.101
4 features · April 6–10
Ultraplan
research preview
Kick off plan mode in the cloud from your terminal, then review the result in your browser. Claude drafts the plan in a Claude Code on the web session while your terminal stays free; when it's ready you comment on individual sections, ask for revisions, and choose to execute remotely or send it back to your CLI. As of v2.1.101 the first run auto-creates a default cloud environment, so there's no web setup step before you can try it.
Run the command, or just include the keyword in any prompt:
```text Claude Code theme={null}
> /ultraplan migrate the auth service from sessions to JWTs
```
Ultraplan guide
Monitor tool
v2.1.98
A new built-in tool that spawns a background watcher and streams its events into the conversation: each event lands as a new transcript message that Claude reacts to immediately. Tail a training run, babysit a PR's CI, or auto-fix a dev server crash the moment it happens, all without a Bash sleep loop holding the turn open.
Ask Claude to watch something while you keep working:
```text Claude Code theme={null}
> Tail server.log in the background and tell me the moment a 5xx shows up
```
This pairs with /loop, which now self-paces: omit the interval and Claude schedules the next tick based on the task, or reaches for the Monitor tool to skip polling altogether.
```text Claude Code theme={null}
> /loop check CI on my PR
```

/autofix-pr
CLI
PR auto-fix landed on the web in Week 13. Now you can turn it on without leaving your terminal: /autofix-pr infers the open PR for your current branch and enables auto-fix for it on Claude Code on the web in one step. Push your branch, run the command, walk away; Claude watches CI and review comments and pushes fixes until it's green.
Run it from the PR's branch:
```text Claude Code theme={null}
> /autofix-pr
```
Auto-fix pull requests
/team-onboarding
v2.1.101
Generates a teammate ramp-up guide from your local Claude Code usage. Run it in a project you know well and hand the output to a new teammate so they can replay your setup instead of starting from defaults.
Run it from a project you've spent real time in:
```text Claude Code theme={null}
