Hands-on with Superpowers, the Claude Code plugin nearing 190,000 GitHub stars

Superpowers, created to solve the chronic problem of AI coding tools going on "planning-less rampages," is a plugin for Claude Code. Going beyond simple coding assistance, this tool acts as a framework that structurally enforces spec-driven development on the AI.

Its main features are as follows.

• Plan-first verification system: It goes through a systematic sequence of writing a plan document → establishing an implementation plan → writing code → verification by a reviewer agent.
• Spec-preserving documentation: The derived spec is saved as a file, so even when sessions change, the AI remembers the agreed-upon requirements and shares them with sub-agents.
• Brainstorming skill: Through Socratic questioning, it draws out the user's requirements in detail and automatically organizes the plan.
• Visual Companion: It visually shows mockups or layouts, relieving the frustration of text-based collaboration.
• Subagent-driven execution: It creates a sub-agent for each task to isolate context, repeating the TDD process in 2-5 minute increments.

Through this, it prevents the AI from writing code without the user's agreement, and makes it possible to trace which requirement in the stated spec every implementation detail came from.
