Superpowers 6.4 is out! It adds support for Muse Code, Open Code 2.0 and Qwen Code. This release introduces a new 'native' execution mode for frontier models & adds a new 'diagnosing-superpowers' skill that can help you understand what needs fixing if Superpowers doesn't work like you'd expect.

How many coding agents do you think are out there? We got curious, so we set our agents loose to build a new public catalog of agents, agent sdks and multiplexers. It's live at alltheagents.org. If we're missing your favorites, please submit them.

I got to join Tom Preston-Warner and Sam Odio as the first guest on their new podcast, AI Worth Using. We talked about Superpowers and how it came to be. Then Tom installed Superpowers live and asked it to rebuild GitHub from scratch. If you want to see how it went, the episode is out now.

I'm pleased to announce Superpowers 6.3. New harnesses: Hermes, Devin CLI & Grok Build Performance with Claude Code with Opus 5 and Codex with GPT 5.6-Sol should be *better* - Claude is now less likely to spawn off duplicate reviewers and Codex is now smarter about how it waits for subagents.

I plopped down $20 for Claude Code and installed the Superpowers plugin from my old friend @s.ly. I fed it the PDF with the MIDI spec and told it what I wanted. Superpowers asked me a few questions about implementation and it wrote a product spec.
