I'm pleased to announce the release of Superpowers 6.4.
This release adds new support for three coding agents: Meta's Muse, OpenCode 2.0 and Qwen Code.
Every new model behaves just a bit differently than the ones before it. As the frontier models get more capable, they also develop new quirks. A lot of the work in this release is meant to help the latest models use Superpowers effectively.
We've done some work on brainstorming and writing-plans to help steer your agents away from skipping steps or doing significant unrequested work.
Superpowers offers two plan execution styles. One is "Subagent-Driven Development", which uses the primary agent session as an orchestrator, dispatching all implementation and test tasks to right-sized subagents with limited context and limited mandates. The other is "Native (inline) Execution", which dates to the earliest days of Superpowers. It was originally intended for a human-in-the-loop flow where you acted as a go-between for two agentic sessions.
As the frontier models have improved, they've gotten better at executing work inline without getting distracted or losing the plot. Superpowers 6.4 reinvents Native Execution (the executing-plans skill) for today's more capable models.
We've been running extensive evals comparing Subagent-Driven Development, Native Execution and "bare metal" implementations with Claude Code. With a frontier model, Native Execution is about twice as fast and half as expensive as Subagent-Driven Development. Building without Superpowers gets you results faster and cheaper, but in our testing, even with Astra and Fable, builds without Superpowers implementation skills are significantly buggier than builds using Superpowers. We are, of course, working hard to make Superpowers faster and cheaper to use. We're currently testing out some fairly big changes to the planning skills that we hope to debut soon.
6.4 also introduces a new diagnosing-superpowers skill, which you can use when a session has done something you didn't expect. It knows how to dig into your coding agent's history to understand what Superpowers was doing and can help you put together a good bug report.
We've done a little bit of work to tune the code reviewer prompts to apply a bit more "what would a reasonable person think?" judgment. This should help overzealous models calm down and converge rather than work themselves into aggressive review loops.

If you install Superpowers from the Superpowers Marketplace (https://github.com/obra/superpowers-marketplace) or from OpenAI Codex, 6.4 is available in your coding agent today. Anthropic and other providers update their plugin marketplaces on their own schedules.
