I am interested in LLM agents for automated research.

Research Interest

Long-term research interests and current focus.

I am interested in LLM agents for automated research, particularly how they maintain and update state and make sequential decisions over long-horizon tasks. My current research focuses on agentic retrieval and dynamic retriever routing.

Research Loop

GitHub

Auditable autonomous experimentation plugin

  • Developed a Codex/Claude Code plugin and deterministic Python runner that extends open-source agent-skill scaffolding into approved execution and evaluation contracts.
  • Enforced Git-worktree isolation, plan-hash approval, metric validation, experiment budgets, and append-only research ledgers.

Margin

GitHub

Local-first research paper companion

  • Built an Electron desktop app for PDF ingestion, figure/table review, evidence-linked Markdown notes, and local SQLite persistence.
  • Integrated Codex App Server for language-preserving note organization while keeping papers and confirmed notes local.

Agent Skill Hub

GitHub

Local skill inventory and diagnostics app

  • Built a local web app that discovers and deduplicates skills across 59 AI coding-agent platform definitions and project roots.
  • Implemented snapshot diffs, H001-H015 health checks, conservative path boundaries, safe prompt generation, and a 157-test verification suite.

YouTube Skill

GitHub

Open-source video publication skill

  • Built Codex/Claude adapters and a shared Python engine for OAuth, resumable uploads, manifest validation, and publication safeguards.
