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.

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.

/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.

/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:

Other wins

Focus view: press Ctrl+O in flicker-free mode to collapse the view to your last prompt, a one-line tool summary with diffstats, and Claude's final response
Guided Bedrock and Vertex AI setup wizards on the login screen: pick "3rd-party platform" for step-by-step auth, region, credential check, and model pinning
/agents gets a tabbed layout: a Running tab shows live subagents with a ● N running count, plus Run agent and View running instance actions in the Library tab
Default effort level is now high for API-key, Bedrock, Vertex, Foundry, Team, and Enterprise users (control with /effort)
/cost shows a per-model and cache-hit breakdown for subscription users

CLAUDE\_CODE\_PERFORCE\_MODE: Edit/Write fail on read-only files with a p4 edit hint instead of silently overwriting
OS CA certificate store is now trusted by default, so enterprise TLS proxies work without extra setup (CLAUDE\_CODE\_CERT\_STORE=bundled to opt out)
Amazon Bedrock powered by Mantle: set CLAUDE\_CODE\_USE\_MANTLE=1
Hardened Bash tool permissions: backslash-escaped flags, env-var prefixes, /dev/tcp redirects, and compound commands now prompt correctly
UserPromptSubmit hooks can set the session title via hookSpecificOutput.sessionTitle
