Hidden Gems
xbtlin/ai-berkshire (3k stars) — Most agent skill repos are generic. This one encodes specific investment philosophies from four legendary investors into structured multi-agent research workflows. The claimed returns are eyebrow-raising but the methodology (multi-agent adversarial analysis, decimal precision, red-line rejection) is genuinely sophisticated. Worth watching whether it holds up under scrutiny. https://github.com/xbtlin/ai-berkshire
aws/agent-toolkit-for-aws (1.3k stars) — Only 2 months old but already the official AWS entry point for coding agents. The devsecops plugin alone (incident investigation, vuln scanning, pen testing via agents) is worth exploring. Will likely become default infrastructure. https://github.com/aws/agent-toolkit-for-aws
gglucass/headroom-desktop (250 stars) — Rust desktop app claiming to "unlock 2x more Claude Code and Codex usage." Tiny but trending in the Rust list. If it actually works, every power user will want it. https://github.com/gglucass/headroom-desktop
Notable Trends
Knowledge graphs are the new RAG: Three independent repos in today's top trending (codebase-memory-mcp, graphify, cognee) all convert unstructured data into queryable graph structures. The industry is moving past "chunk and embed" toward structured knowledge representation. This is the most important architectural shift in agent tooling right now.
"Agent-native" is becoming a real product category: no-mistakes (git validation for agents), design.md (brand specs for agents), page-agent (DOM control for agents), voicebox (voice I/O for agents) — tools are no longer just "AI-powered," they're built specifically as agent infrastructure. The platform layer beneath coding agents is crystallizing fast.
