I tailored an opencode agent with terse, minimum instruction, going as far as using ascii symbols and definitions. Works fine. My conclusion is treat it like a starting point and not a holy bible of everything the model needs to know. I pair this with making sure task files are commented with headers like build scripts so context+instruction is consistent. The happy path then is the LLM pulling in context where it needs it.
