Personal Work
- My open-source personal assistant. The app has its own custom agent-harness with in-house workflow engine, automation planning, history, approvals, with Replicache for instant updates. Supporting cross-integration (
linear,github,sentry) RAG and reply drafting in user's tone here. This is the core behind the boss-worker harness I built specifically for this and how it powers every workflow in the app. - Production code review agent with Merkle-backed incremental indexing, multi-agent AI harness, OSV vuln triage, issue memory, eval suite, and false-positive tracking.
