I've seen a couple of power users already switching to Pi [1], and I'm considering that too. The premise is very appealing:

- Minimal, configurable context - including system prompts [2]

- Minimal and extensible tools; for example, todo tasks extension [3]

- No built-in MCP support; extensions exist [4]. I'd rather use mcporter [5]

Full control over context is a high-leverage capability. If you're aware of the many limitations of context on performance (in-context retrieval limits [6], context rot [7], contextual drift [8], etc.), you'd truly appreciate Pi lets you fine-tune the WHOLE context for optimal performance.

It's clearly not for everyone, but I can see how powerful it can be.
