#1 GOLDReleaseReddit r/ClaudeAI (ClaudeOfficial)

Computer use is now in Claude Code

Claude Code can now open your actual apps, click through the UI, and test what it built — all directly from the CLI, without you touching the keyboard
Works on anything you can open on a Mac: a compiled SwiftUI app, a local Electron build, or any GUI tool that doesn't have a CLI — so Claude can visually verify its own output
This is a research preview, available now on Pro and Max plans on macOS. Enable it with /mcp in Claude Code
Docs at code.claude.com/docs/en/computer-use — this is the first time Claude can close the loop from 'write code' to 'run it and see if it looks right'

#2 SILVERReleaseClaude Code Releases (GitHub)

Adds a new PermissionDenied hook that fires when auto mode blocks an action — return {retry: true} to let the model try a different approach instead of just stopping
Fixes a StructuredOutput schema cache bug that was causing ~50% failure rates in workflows with multiple schemas — a likely silent source of mysterious failures in agent pipelines
Fixes prompt cache misses in long sessions caused by tool schema bytes changing mid-session (a known cost multiplier)
Fixes the misleading 'Rate limit reached' error that was actually an entitlement error — now shows the real message with actionable hints

#3 BRONZEGuideReddit r/ClaudeAI

Bug 1: The standalone Claude Code binary (from claude.ai/install.sh or npm install -g) has a native string replacement that can break your prompt cache if your conversation ever discusses Claude Code's own billing internals — workaround: run via npx @anthropic-ai/claude-code instead
Bug 2: Every --resume since v2.1.69 causes a full cache miss on the entire conversation history — only the system prompt stays cached, so a long session resumed once could cost $3-10 extra in wasted input tokens
