I'm in team matching for @Google's Summer 2027 Research Intern position! I build reliable & safe multi-agent LLM systems and work on automated research agents. Open to related topics as well as new directions!
Potential hosts, let's connect! DMs/emails welcome; reposts very much appreciated 🙏

💡 Millions of shared skills. Why should agents keep starting from scratch?
Excited to share RASO! 🚀
Retrieve shared skill knowledge, adapt it to the target harness, and use it for rollout-free initialization and feedback-driven updates.

5/5 🛰️ → 📊 From satellite imagery to spreadsheets
A retrieved imagery skill handles empty groups before aggregation. Adapting this procedure helps a spreadsheet agent leave missing results blank and avoid shifting values into the wrong rows.
Useful knowledge can cross domains
4/5 📈 Performance
Across 4 benchmarks × 2 LLMs, RASO outperforms TextGrad, GEPA, SkillOpt, and WikiSkill, averaged over 3 seeds.
Gains over the strongest competing baseline reach +6.31 pp on SpreadsheetBench and +11.30 pp on WebShop.
3/5 🔧 Cross-Harness Adaptation
Relevant knowledge may come from skills written for entirely different tools and environments.
We extract the transferable procedure and re-express it using the target harness’s tools, objects, and constraints.
2/5 🔄 RASU: Retrieval-Augmented Skill Update
Observing a failure doesn’t always tell you how to fix it.
RASU uses failed trajectories to guide retrieval, bringing external knowledge into iterative skill refinement alongside execution feedback.
1/5 🚀 RASI: Retrieval-Augmented Skill Initialization
Why wait for expensive rollouts to build a useful skill?
RASI retrieves procedural knowledge using only task and harness descriptions, then adapts and combines it into an initial skill—with zero agent rollouts.
🎉 Thrilled to announce that AgentGrad is accepted to #NeurIPS2026!
🎯 Intervention-guided prompt optimization for multi-agent systems
