- [BUG] iOS app silently crashes when tapping a Remote Control session to link (Code tab)
- [Bug] Anthropic API Error: Connection closed mid-response
- [Bug] Unspecified Internal Server Error (HTTP 500)

- Guys opus is just not usable since 2 days totally lobotomized and slow
- [BUG] iOS app 1.260618.0 hard-crashes opening a Remote Control session — main-thread - stack overflow in Swift KeyPath metadata
- [BUG] VS Code extension: searching doesn't navigate to results off-screen
- Auto-compaction: two compounding cost bugs — stale precompute keeps ~200k tokens verbatim, and that prefix is repeatedly cache-created instead of cache-read
- [Bug] Still reproducing on 2.1.186: assistant hallucinates fake user/system turns with stop_reason=null (re-report of #64791, wrongly auto-closed)
- [Bug] Tasks taking 20-25 minutes instead of seconds/couple minutes - severe performance regression
- AskUserQuestion widget renders only header then hangs in VS Code extension (macOS, called from Skill)

- [FEATURE] Programmatic artifact share-with-org + delete from headless/server CLI sessions
- [BUG] Claude steals focus on startup in vscode
- [Feature Request] Pause rate limit reset timer during Anthropic API service outages
- [BUG] No way to seek/jump in long scrollback — native terminal scrollbar lost, in-app scroll painfully slow (macOS Terminal, Konsole over RDP)
- [BUG] Path-scoped Write(...) allow rules never match (silently ignored) — only Edit(...) rules gate the Write tool
- Add a shell-execution mode that never touches the model or context
- [Bug] Anthropic API Error: 500 Internal Server Error
- [Bug] Anthropic API Error: 500 Internal Server Error
- Fullscreen/NO_FLICKER renderer: Option+Delete (Meta+Backspace) word-delete stops working — classic renderer unaffected
