What is an Agent Chassis?

Jeff Malnick’s post is confident. It’s also detached from how developers actually ship code today and made me furious.“Agent chassis” boils down to: the script that runs your agent. Fine. But the security layer argument collapses when the tooling underneath is fragmented.Right now you pick between CLI, shell plugins, service accounts, connectors, environments — each with different auth models, rate limits, edge cases, and silent failures. None cleanly support a headless agent workflow. I’ve built workarounds for my workarounds.Agentic coding made this obvious. Agents need real credentials at runtime. Not desktop popups. Not biometric prompts in a terminal.The community built unofficial MCP servers. Anthropic shipped 50+ connectors. 1Password isn’t there.The spec is public. It’s buildable. So—who’s shipping it?
