After being a Claude-hater for the last few months, frustrated with weird verbosity and slow churning response, not to mention dealing with a full-organisations worth of shared skills and giant CLAUDE.md docs slowing everything down - super-light Pi is a delight.
Even still, I normally delete every package, skill and agent.md and start configuring again when a new class of model (Astra/Fable/5.5) comes out - I get amazing results with Kimi K3 in Pi. I really really love pi lol.
Other than quite liking Codex desktop now... I also recommend everyone tries building a harness of some sort. Vercel Eve is really fun to play with if you have a Vercel account and consider that a type of harness, or at the very least build a control-plane/UI for a harness on top of the Pi RPC SDK which is incredible.
I personally have a custom web ui powered by diffs.com and drag and drop "pipelines", where I can orchestrate steps instead of skills (although they're basically skills) + custom compaction and summary relay between the steps with a small fast model.
I also have iOS/Android apps that look like Trello boards, which communicate over Cloudflared/Tailscale to a thin Pi server that provides github integration and some custom tooling to render "ask user" prompts and co-ordinates worktrees and PR creation.
https://fx.sh is also cool.
All in all - use your spare tokens to build and try harnesses, build alternate harness UIs, and build alternate workflow co-ordinators away from just "/invoke-skill" or a TUI-based chat.
It's a great combo for software dev and priced lower than the Anthropic and OpenAI models.
