Superpowers 6: builds up to 50% faster and 60% cheaper

Superpowers 6

Jesse Vincent shipped Superpowers 6, an orchestration tool for AI coding agents. An overnight auto-research loop driven by Anthropic's Fable merged code review and spec-compliance review into one step and optimized how reviewers receive diffs, cutting wall-clock time by 50% and token spend by 60% on Anthropic evals. The gains did not transfer to OpenAI Codex—the post says Codex reviewers ignored the task brief. Fable also found that capping the coordinator's thinking budget backfires and that implementation bodies in plans are marginal.

Why it matters: Superpowers 6 ships hard numbers — 50% faster builds, 60% cheaper tokens — and the merged review step is a concrete optimization worth knowing. But it's a personal tool blog, not a product launch or industry event, so audience fit is narrow. Lands right at the featured threshold.
