| Attribute | Impeccable | Superpowers |
|---|---|---|
| Purpose | Design guidance for coding agents: one skill, 24 commands, and design detector rules. | A software development method for coding agents, built from composable skills. |
| Documented capabilities | 24 design commands such as polish, audit and critique, 59 deterministic design detector rules, Live browser iteration, PRODUCT.md project context | Spec-first brainstorming before code, Written implementation plans, Subagent-driven development with task review, Skills that trigger automatically |
| Best-fit workflow | Teams that want agent-built interfaces reviewed against explicit design rules. | Teams that want coding agents to plan and review before they write code. |
| Check before choosing | The deterministic rules run without a model; critique commands use your agent's model. | It changes how your agent works on every task. Try it on a side project first, and install it separately for each agent you use. |
