Claude Code ships Ultraplan cloud mode, Monitor tool, and terminal-side PR auto-fix
TL;DR
Claude Code's April 6 to 10 release cycle shipped four significant features: Ultraplan cloud plan mode (draft in browser, execute anywhere), a Monitor tool for background watchers, terminal-side PR auto-fix via /autofix-pr, and /team-onboarding to generate teammate ramp-up guides.
What changed
What shipped
Claude Code released v2.1.92 through v2.1.101 between April 6 and April 10. Four major features plus a long list of quality-of-life improvements.
Ultraplan research preview
Run /ultraplan or include the keyword in any prompt. Claude drafts a plan in a Claude Code on the web session while your terminal stays free. Comment on individual sections in the browser, ask for revisions, then choose to execute remotely or send the finalised plan back to your CLI. As of v2.1.101 the first run auto-creates a default cloud environment, so there is no web setup step.
Example: "> /ultraplan migrate the auth service from sessions to JWTs"
Monitor tool
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 Claude reacts to immediately. Tail a training run, babysit a PR's CI, auto-fix a dev server crash the moment it happens, with no Bash sleep loop holding the turn open.
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.
/autofix-pr in the terminal
PR auto-fix shipped on the web in Week 13. Now /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 is green.
/team-onboarding
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.
Other wins
- •Focus view. Press Ctrl+O in flicker-free mode to collapse the view to your last prompt, a one-line tool summary, and Claude's final response.
- •Bedrock and Vertex AI setup wizards. Pick "3rd-party platform" on the login screen for guided auth, region, and model pinning.
- •/agents tabbed layout. Running tab shows live subagents with a count; Library tab has Run agent and View running instance actions.
- •Default effort "high". For API-key, Bedrock, Vertex, Foundry, Team, and Enterprise users. Override with /effort.
- •/cost per-model breakdown. Subscription users get cache-hit breakdowns.
- •/release-notes interactive version picker. Browse versions without leaving the terminal.
- •Perforce mode. CLAUDE_CODE_PERFORCE_MODE makes Edit and Write fail on read-only files with a p4 edit hint, instead of silently overwriting.
- •OS CA cert store trusted by default. Enterprise TLS proxies now work without extra setup.
- •Amazon Bedrock powered by Mantle. Set CLAUDE_CODE_USE_MANTLE=1.
- •UserPromptSubmit hook session titles. Hooks can set the session title via hookSpecificOutput.sessionTitle.
Who this matters for
- Vibe Builder: /ultraplan lets you draft a migration plan in the browser, review it with comments, then run it back in your terminal. No more 'did I miss a step' moments before kicking off a big change.
- Basic User: /team-onboarding generates a ramp-up guide for new teammates from your own usage patterns. Useful if you are handing off a project you have been working on solo.
- Developer: Monitor tool replaces every sleep-poll loop you have ever written. Perforce mode prevents silent overwrites on read-only files. Default effort high on API tier means less manual /effort tweaking.
What to watch next
Week 15 is a heavier-than-average release cycle and the Monitor tool is the feature most people will underestimate. Background watchers streaming events into the same conversation changes what is possible for long-running tasks. No more "sleep 60 then check" loops burning through context. Tail a CI run, auto-fix a dev server crash mid-conversation, have Claude reach for the watcher instead of polling. For anyone running agents on real infrastructure, this is a durability unlock.
Ultraplan is the feature most visible to vibe builders. Kick off a plan from the terminal, review the plan in a browser session where you can comment and ask for revisions, then execute on your CLI or remotely. It is the first time Claude Code has split the planning surface from the execution surface cleanly. Expect this to become the default flow for any non-trivial change within a few weeks.
/autofix-pr graduating to the terminal matters because it means you no longer have to be signed into Claude Code on the web to use it. Push a branch, type /autofix-pr, walk away. This is the kind of quiet feature that makes Claude Code feel less like a chat tool and more like a coworker you can delegate to.
For developers already deep in Claude Code, the Perforce mode, default effort, and Bedrock/Vertex setup wizards are unambiguous quality-of-life wins. If you are on Enterprise, turn on the new defaults and stop overriding effort every session.
