This release introduces powerful file @-mentioning capabilities in the WUI editor, enhanced error handling, and several important UI fixes for a more stable and polished experience.

Installation

brew install --cask --no-quarantine humanlayer/humanlayer/codelayer-nightly
# kill any existing hld process and open CodeLayer with current shell PATH so it can find your `claude` CLI
pkill hld; open /Applications/CodeLayer-Nightly.app

• if your claude cli is not in a very-default location like /usr/local/bin, you will need to launch with open /Applications/CodeLayer-Nightly.app rather than launching from Spotlight/Finder/Raycast/etc
• if you see a swift error about xattr, that is usually safe to ignore

Features

• File @-mentioning with fuzzy search, drag-and-drop support, and clickable tooltips - @balanceiskey (#524)
• Global OS hotkey (Cmd+Shift+H) for quick session creation with keyboard-driven interface - @samdickson22 (#516)

Fixes

• Added error boundary protection for TipTap editor to prevent crashes - @balanceiskey (#522)
• Fixed timestamp layout shifts when relative times update - @samdickson22 (#520)
• Fixed Cancel/Deny buttons incorrectly opening tool inspect modal - @samdickson22 (#519)

Changes

• Reverted additional directories feature due to stability issues - @samdickson22 (#529)

Troubleshooting / Known Issues

• If install fails, ensure you've cleaned up all previous artifacts. brew reinstall is worth a shot as well.
• Logs can be found at ~/Library/Logs/dev.humanlayer.wui.nightly/CodeLayer-Nightly.log
• If daemon fails due to already running, you can pkill hld and reopen CodeLayer to try again
• If opening from spotlight/alfred/raycast/finder fails, try pkill hld; open /Applications/CodeLayer-Nightly.app to push your PATH into CodeLayer so it can better find your claude CLI
