Measured comparison: Superpowers vs Compound Engineering plugins
AlexKim · x · 2026-08-29
A deep dive comparing two Claude plugins: Superpowers and Compound Engineering.
Key Difference:
- Superpowers uses a SessionStart hook to inject skills into every session, making it expensive to install but constantly active.
- Compound Engineering is invoked on demand, writes knowledge back to disk, and lacks global hooks, relying on 298 reference files loaded as needed.
Metrics:
- Superpowers: 143 skills, 1,482 words per skill, 25 reference files.
- Compound Engineering: 33 skills, 34,098 total instruction words, 298 reference files.
They overlap on six skills and are not mutually exclusive; most repos should run both.
