It’s painfully obvious that you can just open your coding harness and… tell it you’d like to make an agent. They’re simple to write.

The agent isn't the hard part - it's the orchestration, skills, research systems, adversarial reviews, dreaming/compounding, context management and all the rest. Plus all the annoying hygiene tools to "poke the agent that got a clear prompt and decided to just sit there and wait for no good reason" and "delete the remote branches that the prompt told all the agents to delete but some of them forgot to":)

This is where it's nice to have some guardrails -- coding agents work etremely well with limitations.
