> What's a second generation agent?

i meant that i initially developed an agent harness as a set of skills integrated with opencode and now i am in the process of using that to write a new agent from scratch to replace opencode.

yes. i think tests and setting up feedback loops for diagnosing errors (logs, debugging, etc) are the most important things. in my experience deepseek-v4-flash tends to ignore instructions to use these tools and default to churning through code and guessing the cause of errors, which is often wrong, so it requires occasionally stepping in when it has been grinding fruitlessly for a while and reminding it, probably due to context length and sparse attention forgetting instructions that are put in context at the beginning of a session.
