What I build

I work where AI prototypes become dependable systems: agent architecture, evaluation, orchestration, and the engineering controls that make autonomous work observable and verifiable.

我专注于企业级 AI 应用与智能体工程,让原型真正具备可评估、可追踪、可交付的生产能力。

Selected work

Project What it explores
octopus-skill 🐙 Graph engineering for long-horizon agents: clean-context roles, durable state, and verified completion across Claude Code, Grok, Cursor, and Codex.
obsidian-llm-wiki A maintainable knowledge system inspired by the LLM Wiki model, with namespace architecture, layered indexes, and reusable agent skills.
sherlock-claude AI-assisted code analysis that turns repositories and runtime logs into focused diagnoses and actionable fix recommendations.

Current focus

  • Agent systems — specialized roles, durable coordination, and bounded autonomy
  • Evaluation & reliability — evidence-based acceptance, regression gates, and failure analysis
  • Developer experience — tools that make advanced AI workflows easier to operate and inspect
  • Knowledge engineering — structured context that stays useful as teams and codebases evolve

Engineering principles

Make the state inspectable. Make “done” verifiable. Keep the system smaller than the problem it solves.
