you already have the world’s smartest assistant. you just need to know how to talk to it. “think step by step” → reasoning mode
“find flaws in your answer” → self-check mode
“explain like i’m 5” → easy mode
“adopt the expert role of [role]” → expert mode

Ecosystem Adopts AGENTS.md Standard for Coding Agent Instructions
By
–
The ecosystem is nascent, and many different file names popped up to provide context and instructions to coding agents. The @OpenAI Codex team chose http://
AGENTS.md, a neutral name, so others could adopt it. -

Improving LLM Performance Through Advanced Prompting Techniques
By
–
This might be the most practical LLM thread I’ve read all year. Most people never get past zero-shot and then wonder why “GPT is mid.” This levels you up fast.

Chain-of-Thought prompting compared to modular code
By
–
The analogy to modular code hit hard. Imagine building an entire app in one function. That’s what we’re doing with CoT.

The importance of context engineering for AI agents
By
–
Context engineering might quietly be the most important concept here. If your agent has bad context, it doesn’t matter how smart the model is.

Technical Configuration Tips for RAG System Optimization
By
–
RAG configuration tips from the paper: • Don’t over-retrieve; more context isn’t always better
• Chunk-level summaries are high ROI
• Tune top-k per task type
• Retrieval granularity (utterance vs session vs chunk) changes everything
• Align your memory format to how the -
Memory design and retrieval strategies in AI models
By
–
Memory design matters more than model size OdysseyBench evaluated multiple retrieval strategies: • Long-context prompting (8K+ tokens)
• RAG with raw session or utterance context
• RAG with summarization: session or chunk Chunk-level summaries outperformed all, with ~75%
