Simon Willison pointed Claude Code at a single prompt and walked away. Twelve hours later, he had a full SPARQL 1.1 implementation in Rust that runs inside SQLite, complete with multiple crates, READMEs, and a tutorial. He also had a problem: the code works, but he cannot feasibly review it, and he's not sure what to do with it.

This is the sharp edge of agent orchestration at scale. When dynamic workflows spawn subagents that partition work across modules, the human who commissioned the project loses the ability to audit, understand, or maintain the output. The code runs. The tests pass. The documentation exists. But the human is no longer in the loop.

How Ultracode Orchestration Works

Claude Code's Ultracode mode uses dynamic workflows to coordinate subagents.…
