Favors terminal-style coding agents with strong tool loops, code review, and deliberate model experimentation.
“If you were trying and failing to use an LLM for code 6 months ago, you're not doing what most serious LLM-assisted coders are doing.” fly.io

Used by Claude in the Markdown-viewer experiment.
Unix tools, Git, tests, linters, and MCP
His account of serious coding agents emphasizes arbitrary Unix tools, Git, compile/test loops, and MCP integrations.
Workflow
- 1Let agents inspect code, author files, run tools, compile, test, and iterate.fly.io, 2025-06
- 2Read the resulting code and spend a few minutes correcting style and direction.fly.io, 2025-06
- 3Run asynchronous agents on multiple tasks, then curate their pull requests.fly.io, 2025-06
- 4Treat context, tools, and sub-agents as programmable parts of an agent.fly.io
Config
Public project-level AGENTS.md; it records a lower-power model for subagents and a build/test workflow, but is not proof of his personal global config.
