About me
I am Guanqi. I work on local-first AI developer tools and agent runtimes. I am less interested in another chat interface than in the infrastructure agents need to work inside real engineering environments: search, indexing, state, tool calls, long tasks, and desktop integration.
My current product work is centered on BitFun. The questions I care about are practical: how an agent searches a real workspace, restores context, traces tool execution, resumes long tasks, and uses a desktop runtime as its working surface.
The other thread is flashgrep, a local regex prefilter index system for large Git worktrees. It first recalls candidate files through a character-level inverted index, then performs exact regex verification. That project reflects how I think about agent tooling infrastructure: speed, correctness, incremental state, and external protocols have to hold together.
Current threads
- BitFun: a desktop-grade agent runtime and agent-app work surface.
- flashgrep: local search and indexing infrastructure for agents and large repositories.
Interests
- Agent runtime: sessions, tools, memory, state, debugging, and long-task execution.
- Workspace search: regex prefiltering, base snapshots, published overlays, and daemon protocols.
- Local work surfaces: filesystem, terminal, browser, and computer use as one controllable workspace.
