> example I have rules when using Pi to ask main agent to dispatch implementer agents in parallel using git worktrees. Some time it uses git worktrees, sometimes no

I've taken the approach that whenever this happens, it's my fault. The instructions were not clear enough, not direct enough, or more often, there's just too many of them.

I'm now at the point where my pi system prompt + agents + skills + tools starts out at just 7k context. It's all very clear and concise. I almost never have ambiguous responses like this, at least not bear the start of a session.

Combined with instructions to keep the main session as a coordinator and use subagents for all non trivial work, I can get a lot of work done before hitting 100k context and basically never go over 150k.

It's a stark contrast with Claude code where I was starting at about 35k context even after trimming my stuff down. It's hardly surprising if an agent doesn't know what to do if you dump 30k+ of context with all kinds of rules and workflows, most of them unrelated to the current tasks, before you even do anything.
