Best AI Agent Frameworks for Codex CLI

Superpowers is an agentic software development framework that provides coding agents with a complete methodology for building software more carefully and consistently. The framework is built around composable skills that automatically guide agents through the right workflow at each stage of development. Instead of immediately generating code, an agent using Superpowers first clarifies the user’s goal, develops a specification, and presents the design in readable sections for approval. Once the design is approved, the agent creates a detailed implementation plan with small tasks, exact file paths, verification steps, and testing expectations. Superpowers strongly emphasizes true test-driven development, including writing failing tests first, making them pass, refactoring, and committing only after verification. The framework can use subagents to complete tasks, inspect work, review implementation quality, and continue progressing through a structured plan. It includes skills for brainstorming, writing plans, executing plans, systematic debugging, code review, git worktrees, and finishing development branches. Superpowers supports multiple coding environments, including Claude Code, Codex, Gemini CLI, OpenCode, Cursor, Factory Droid, and GitHub Copilot CLI. Superpowers helps software teams reduce agentic mistakes, improve code quality, and make AI-assisted development more predictable.
