🎥 WORTH WATCHING

Karpathy @ Sequoia AI Ascent 2026: "From Vibe Coding to Agentic Engineering" (30 min) The talk of the day. A year after coining "vibe coding," Karpathy says he's never felt more behind as a programmer. Covers Software 3.0, LLMs as "ghosts not animals," verifiability gaps, and production AI work. Key quote: "You can outsource your thinking, but you can never outsource your understanding." 🔗 https://www.youtube.com/watch?v=96jN2OCOfLs 🔗 X: https://x.com/stephzhan/status/2049518659513852109

💡 TECHNIQUES & IDEAS

Agentic Harness Engineering (AHE) New paper from Fudan & Peking University — a framework where coding agents automatically improve their own harnesses. Agents optimizing their own tooling. 🔗 X: https://x.com/carlosvillu/status/2049584017880551450

Claude Multi-Agent V2 Protocol Anthropic's experimental V2 shifts from opaque agent IDs to named tasks in an agent tree. New primitives: send_message, followup_task, list_agents. More ergonomic for large delegation. 🔗 X: https://x.com/marmaduke091/status/2049513823892045828

🔮 EMERGING TRENDS

Agentic Engineering > Vibe Coding Karpathy's talk crystallized what's been brewing: "vibe coding raised the floor, agentic engineering raises the ceiling." The shift from prompting AI to orchestrating agent systems — subagents, skills, commands, workflows. Solo devs shipping like teams of 10.

Agent Memory Wars Three separate memory-for-agents repos trending in one day (MemOS, automem, mind). Persistent memory is the missing piece everyone's trying to solve. MemOS's OpenClaw plugin is interesting.

MCP Everywhere Google (databases), Autodesk (3D design), Higgsfield (video), and security labs all shipping MCP integrations. The protocol is becoming the USB of AI tooling.

AI Agent RAM Management With devs running 50+ agents in parallel, resource management is becoming a first-class concern. Orca's sleep/resume with zero context loss is early but points to where agent infrastructure is heading.

Firefox's Secret Ad Blocker Mozilla quietly shipped a Rust-based Brave-derived adblock engine in Firefox 149. No announcement, disabled by default, buried in about:config. Testing a full uBlock replacement.
