Claude Sonnet 4.5: First Impressions (Claude Code 2.0 + Agent SDK)

Claude Sonnet 4.5 + Claude Code 2.0 are here — and Anthropic FINALLY added usage limit visibility that everyone’s been asking for! In this video, I share my first impressions of Sonnet 4.5, walk through the new Claude Code 2.0 features (checkpoints, native VS Code extension, and the Claude Agent SDK), and show how context editing + memory tools extend conversations and preserve project state. After a month of degraded performance and frustrating rate limits, this release addresses many of those pain points. You’ll see the new usage tracking dashboard, context window analysis, plan mode changes, and whether the benchmarks actually matter. What’s new in Claude 4.5 + Code 2.0: • Usage limits dashboard • Context editing & memory tool • Checkpointing in Claude Code • Native VS Code extension • Claude Agent SDK (formerly Code SDK) ⌚ TIMESTAMPS 00:45 - Claude Sonnet 4.5 overview 01:30 - Key features and announcements 02:10 - Context editing explained 04:40 - Claude Agent SDK 05:26 - First look at Claude Desktop 05:37 - Rate limit initial impressions 06:05 - VS Code extension 06:45 - MCP server toggles (missing feature) 07:05 - New Claude Code 2.0 interface 07:15 - Plan mode availability 07:50 - Context window analysis 08:33 - Final thoughts 🔗 RELEVANT LINKS Sonnet 4.5 Announcement → https://www.anthropic.com/news/claude-sonnet-4-5 Claude Agent SDK → https://docs.claude.com/en/api/agent-sdk/overview Claude Code Autonomy Update → https://www.anthropic.com/news/enabling-claude-code-to-work-more-autonomously Context Management → https://www.anthropic.com/news/context-management Book a call with me → https://yedatechs.com/#container06 Sponsorship inquiries → hi@yedatechs.com #ClaudeSonnet45 #ClaudeCode2 #Anthropic #ClaudeAgentSDK #VSCodeExtension #AICoding #UsageLimits #ContextEditing #AIAgents #ClaudeDesktop #DeveloperTools #MachineLearning #CodeGeneration #AIProductivity #ClaudeAPI #MCPServers #PlanMode #Checkpoints #CodingAI
