Codex Plugin for Claude Code (Official from OpenAI) OpenAI dropped an official Codex plugin for Claude Code.

Plus a Review Gate that auto-blocks problematic code. 🔗 X: https://x.com/DivyanshT91162/status/2050797118580044088 💻 GitHub: https://github.com/openai/codex-plugin-cc

🎥 WORTH WATCHING

Boris Cherny (Creator of Claude Code) on Token Waste Explains why you're burning 73% of your context window before you even start. Patterns to cut token waste dramatically. Multiple tweets referencing this as must-watch content. 🔗 X: https://x.com/VisualconAI/status/2050920763994087526 🔗 X: https://x.com/RoundtableSpace/status/2050881804077326376

💡 TECHNIQUES & IDEAS

MCP's 5 Primitives Most People Don't Know An Anthropic engineer revealed that most people only use MCP for tool-calling (20% of capability). The other 4 primitives: Prompts (inject templates into context), Resources (raw data exposure for RAG), Sampling (servers request completions from client's model), and Roots (workspace/project context). Plus upcoming: OAuth 2.1, Streamable HTTP, official registry, Ruby SDK from Shopify, Go SDK from Google. 🔗 X: https://x.com/cyrilXBT/status/2050760292611584058

NotebookLM → Claude Skills Pipeline People are using NotebookLM to batch-generate Claude Skills: feed in curated docs, let it understand/organize/distill, output as reusable skill.md files. Turns Claude into a "trained vertical expert" without repeated prompting. 🔗 X: https://x.com/AIExplorerTim/status/2050847421601808854

10 GitHub Repos That Make Claude More Useful Curated list including: repomix (pack entire codebase into one AI-readable file, 20K+ stars), design-ai (DESIGN.md files from Stripe/Linear/Vercel), awesome-claude-code, and the Karpathy-derived CLAUDE.md (100K+ stars). 🔗 X: https://x.com/Yash_Kavaiya_/status/2050991259695927421

🔮 EMERGING TRENDS

"Multiplayer is the New Moat" From a panel with Anthropic, Linear, and Raycast engineering leaders: everyone can vibe-code solo apps now, but collaborative/multiplayer software is still genuinely hard. Linear is becoming the "agent orchestration layer" with separate boards managed entirely by agents. Key quote: "AGI is already here." 🔗 X: https://x.com/cnorth_13/status/2050666328273367372

Adversarial AI Code Review is Going Mainstream The Codex-in-Claude-Code pattern signals a shift: instead of asking "which model is best?", developers are making models compete. Claude writes, Codex challenges. The tension produces better code. Expect more multi-model adversarial workflows.

Agent Memory is Getting Serious ReMe, file-based memory systems, and context management frameworks are proliferating. The community is moving past "chatbot with tools" toward agents with real persistent memory and cross-session continuity.

Claude Skills Ecosystem Exploding Multiple viral threads on building, sharing, and automating Claude Skills. Community skill libraries hitting tens of thousands of installs. The plugin/skill marketplace is becoming Claude's app store moment.
