# Week 13 · March 23–27, 2026
> Auto mode for hands-off permissions, computer use built in, PR auto-fix in the cloud, transcript search, and a PowerShell tool for Windows.
Releases v2.1.83 → v2.1.85
6 features · March 23–27
Auto mode
research preview
Auto mode hands your permission prompts to a classifier. Safe edits and commands run without interrupting you; anything destructive or suspicious gets blocked and surfaced. It's the middle ground between approving every file write and running with --dangerously-skip-permissions.
Cycle to auto with Shift+Tab, or set it as your default:
```json .claude/settings.json {3} theme={null}
{
"permissions": {
"defaultMode": "auto"
}
}
```
Permission modes guide
Computer use
Desktop
Claude can now control your actual desktop from the Claude Code Desktop app: open native apps, click through the iOS simulator, drive hardware control panels, and verify changes on screen. It's off by default and asks before each action. Best for the things nothing else can reach: apps without an API, proprietary tools, anything that only exists as a GUI.
Enable it in Settings, grant the OS permissions, then ask Claude to verify a change end to end:
```text Claude Code theme={null}
> Open the iOS simulator, tap through the onboarding flow, and screenshot each step
```
Computer use guide
PR auto-fix
Web
Flip a switch when you open a PR and walk away. Claude watches CI, fixes the failures, handles the nits, and pushes until it's green. No more babysitting a PR through six rounds of lint errors.
After creating a PR on Claude Code web, toggle Auto fix in the CI panel.
Auto-fix pull requests
Transcript search
v2.1.83
Press / in transcript mode to search your conversation. n and N step through matches. Finally a way to find that one Bash command Claude ran 400 messages ago.
Open transcript mode and search:
```text Claude Code theme={null}
Ctrl+O # open transcript
/migrate # search for "migrate"
n # next match
N # previous match
```
Fullscreen guide
PowerShell tool
preview
v2.1.84
Windows gets a native PowerShell tool alongside Bash. Claude can run cmdlets, pipe objects, and work with Windows-native paths without translating everything through Git Bash.
Opt in from settings:
```json .claude/settings.json {3} theme={null}
{
"env": {
"CLAUDE_CODE_USE_POWERSHELL_TOOL": "1"
}
}
```
PowerShell tool docs
Conditional hooks
v2.1.85
Hooks can now declare an if field using permission rule syntax. Your pre-commit check only spawns for Bash(git commit \*) instead of every bash call, cutting the process overhead on busy sessions.
Scope a hook to git commits only:
```json .claude/settings.json {5} theme={null}
{
"hooks": {
"PreToolUse": [{
"hooks": [{
"if": "Bash(git commit *)",
"type": "command",
"command": ".claude/hooks/lint-staged.sh"
}]
}]
}
}
```

# Week 14 · March 30 – April 3, 2026
> Computer use in the CLI, interactive in-product lessons, flicker-free rendering, per-tool MCP result-size overrides, and plugin executables on PATH.
Releases v2.1.86 → v2.1.91
5 features · March 30 – April 3
Computer use in the CLI
research preview
Last week computer use landed in the Desktop app. This week it's in the CLI: Claude can open native apps, click through UI, test its own changes, and fix what breaks, all from your terminal. Web apps already had verification loops; native iOS, macOS, and other GUI-only apps didn't. Now they do. Best for closing the loop on apps and tools where there's no API to call. Still early; expect rough edges.
Run /mcp, find computer-use, and toggle it on. Then ask Claude to verify a change end to end:
```text Claude Code theme={null}
> Open the iOS simulator, tap through onboarding, and screenshot each step
```
Computer use guide
/powerup
v2.1.90
Interactive lessons that teach Claude Code features through animated demos, right inside your terminal. Claude Code releases frequently, and features that would have changed how you work last month can slip by. Run /powerup once and you'll know what's there.
Run it:
```text Claude Code theme={null}
> /powerup
```
Commands reference
Flicker-free rendering
v2.1.89
Opt into a new alt-screen renderer with virtualized scrollback. The prompt input stays pinned to the bottom, mouse selection works across long conversations, and the flicker on redraw is gone. Unset CLAUDE\_CODE\_NO\_FLICKER to roll back.
Set the env var and restart Claude Code:
```bash theme={null}
export CLAUDE_CODE_NO_FLICKER=1
claude
```
Fullscreen rendering
MCP result-size override
v2.1.91
MCP server authors can now raise the truncation cap on a specific tool by setting anthropic/maxResultSizeChars in the tool's tools/list entry, up to a hard ceiling of 500K characters. The cap used to be global, so tools that occasionally returned inherently large payloads like database schemas or full file trees hit the default limit and got persisted to disk with a file reference. Per-tool overrides keep those results inline when the tool really needs them.
Annotate the tool in your server's tools/list response:
```json highlight={5} theme={null}
{
"name": "get_schema",
"description": "Returns the full database schema",
"_meta": {
"anthropic/maxResultSizeChars": 500000
}
}
```
MCP reference
Plugin executables on PATH
v2.1.91
Place an executable in a bin/ directory at your plugin root and Claude Code adds that directory to the Bash tool's PATH while the plugin is enabled. Claude can then invoke the binary as a bare command from any Bash tool call, with no absolute path or wrapper script needed. Handy for packaging CLI helpers next to the commands, agents, and hooks that call them.
Add a bin/ directory at the plugin root:
```text highlight={4, 5} theme={null}
my-plugin/
├── .claude-plugin/
│ └── plugin.json
└── bin/
└── my-tool
```
Plugins reference
Other wins
Auto mode follow-ups: new PermissionDenied hook fires on classifier denials (return retry: true to let Claude try a different approach), and /permissions → Recent lets you retry manually with r
New defer value for permissionDecision in PreToolUse hooks: -p sessions pause at a tool call and exit with a deferred\_tool\_use payload so an SDK app or custom UI can surface it, then resume with --resume
/buddy: hatch a small creature that watches you code (April 1st)
disableSkillShellExecution setting blocks inline shell from skills, slash commands, and plugin commands
Edit tool now works on files viewed via cat or sed -n without a separate Read
Hook output over 50K saved to disk with a path + preview instead of injected into context
Thinking summaries off by default in interactive sessions (showThinkingSummaries: true to restore)
Voice mode: push-to-talk modifier combos, Windows WebSocket, macOS Apple Silicon mic permission
claude-cli:// deep links accept multi-line prompts (encoded %0A)

# What's new
> A weekly digest of notable Claude Code features, with code snippets, demos, and context on why they matter.
The weekly dev digest highlights the features most likely to change how you work. Each entry includes runnable code, a short demo, and a link to the full docs. For every bug fix and minor improvement, see the [changelog](/en/changelog).
**Computer use** comes to the CLI in research preview: Claude can open native apps, click through UI, and verify changes from your terminal. Best for closing the loop on things only a GUI can verify.
Also this week: `/powerup` interactive lessons, flicker-free alt-screen rendering, a per-tool MCP result-size override up to 500K, and plugin executables on the Bash tool's `PATH`.
[Read the Week 14 digest →](/en/whats-new/2026-w14)
**Auto mode** lands in research preview: a classifier handles your permission prompts so safe actions run without interruption and risky ones get blocked. The middle ground between approving everything and `--dangerously-skip-permissions`.
Also this week: computer use in the Desktop app, PR auto-fix on Web, transcript search with `/`, a native PowerShell tool for Windows, and conditional `if` hooks.
