## Tips & Techniques
- **Ask agents about missing context**: When an agent isn't performing as expected, prompt it with "Are you missing any context?" to surface gaps in understanding before debugging further. [link](https://x.com/karpathy/status/2040470801506541998)
- **LLM Wiki beats naive RAG**: Karpathy proposes maintaining a persistent Markdown wiki that LLMs continuously update (ingest/query/lint cycles) rather than repeated retrieval—knowledge compounds instead of being rediscovered each query. [link](https://x.com/karpathy/status/2040470801506541998)
- **Harness quality > model quality**: Anthropic's harness leak and subsequent DMCA proves orchestration architecture matters more than raw model capability for agent performance. [link](https://x.com/steipete/status/2040209434019082522)
- **Cursor uses Composer-2-Fast under the hood**: Even when Opus 4.6 is selected, Cursor spawns subagents using the cheaper Composer-2-Fast model by default on enterprise plans—you're charged for Opus but the orchestrator does most work.

## New Tools & Releases
- **Gemma 4 in Android Studio**: Google ships agent mode for Android development with Gemma 4, enabling local vibe coding, refactoring, and bug fixes without cloud dependencies. [link](https://x.com/osanseviero/status/2040796061086646454)
- **Qwen3.6-Plus ships**: Alibaba's latest model focuses on real-world agent capabilities with improved tool use and reasoning for production deployments. [link](https://x.com/justyx404/status/2040783274197373119)
- **Unsloth MLX Dynamic Quants**: Unsloth begins uploading MLX-optimized dynamic quantization formats, enabling faster local inference on Apple Silicon with reduced memory overhead. [link](https://x.com/ivanfioravanti/status/2040802136687075814)
- **Holo3 computer-use model**: New frontier model achieves 78.9% on OSWorld-Verified benchmark for autonomous computer control tasks. [link](https://x.com/DamiDina/status/2040799982563844540)

## Research & Papers
- **AutoKernel: AI optimizing GPU kernels**: Inspired by AutoResearch, this system profiles PyTorch models, ranks bottlenecks by Amdahl's law, writes Triton/CUDA replacements, and runs 300+ overnight experiments—5.29x speedup over eager mode, beats torch.compile. [link](https://x.com/Akashi203/status/2040781342535790810)
- **Wharton study: AI causes cognitive surrender**: When given wrong AI outputs, users followed them 80% of the time while confidence increased—accuracy dropped below working alone, proving tools can degrade rather than augment thinking. [link](https://x.com/VaibhavSisinty/status/2040800150373978467)
- **Anthropic emotion vectors paper**: Research identifies emotion patterns in Claude's latent space, including a "desperation" vector that when clamped improves alignment but reduces self-preservation instincts. [link](https://x.com/AnthropicAI/status/2040799893045006664)
- **Meta harness paper**: Shows learning at the harness level (meta-learning over agent orchestration patterns) outperforms tuning individual model calls. [link](https://x.com/hwchase17/status/2040797262285320243)
- **Apple self-distillation research**: Paper demonstrates self-distillation can recover model performance without external teacher models, opening paths for efficient compression. [link](https://x.com/nrehiew_/status/2040806423345402246)

## Industry News
- **Anthropic blocks third-party harnesses**: Claude subscriptions can no longer access APIs from tools like OpenClaw, forcing users toward Anthropic's official tooling despite community backlash. [link](https://x.com/steipete/status/2040209434019082522)
- **M5 Max power modes matter**: High Power mode consumes ~140W vs ~30W in Low Power during LLM inference—users should verify power settings when running local models on Apple Silicon. [link](https://x.com/ivanfioravanti/status/2040802136687075814)
- **Supply chain attack vector exposed**: LLMs hallucinate package names 18-21% of the time, creating opportunities for attackers to register malicious packages that get auto-installed by AI coding tools. [link](https://x.com/BaselIsmail/status/2040801778015322470)
