Projects

Open tools and products I build outside my day job, plus a short bibliography of earlier talks and open-source work.

Current

Tubeless, Managed Agentic Workflows, framed by a looping road and colored stripes.
Tubeless

Pipelines and agents, built from TypeScript functions. Define a pipeline and get retries, concurrency, cached step outputs, checkpointing, and progress tracking for free. Tubeless runs locally or remotely, includes dry runs, a CLI, and a web UI, and also runs agents that choose and change their next steps as they work.

Agent Smith

Evidence-based tuning for coding agents. A plugin for Claude Code, Codex, Gemini CLI, OpenCode, Pi, and Grok that watches real sessions, records what happens, and turns it into concrete recommendations for prompts, settings, and workflow.

Script Bible gold bookmark and wordmark on rich brown leather.
Script Bible

Bible study with semantic search. Find passages by wording or meaning, explore more than 430,000 cross-references, and study Hebrew and Greek words in context. Reading plans and offline reading are included. Free and ad-free, with public Scripture tools available to agents through a remote MCP server.
