Five GitHub repos provide reusable AI agent skills for software development

Superpowers bundles a methodology that guides agents through brainstorming, implementation planning, test‑driven development, systematic debugging, and verification, and it works with Claude Code, Codex, Cursor, Gemini CLI, OpenCode, and others. Skills for Real Engineers offers small, composable skills like grill‑with‑docs and tdd that can be combined into custom pipelines. ECC adds memory, continuous learning, and a security scanner called AgentShield, while Awesome LLM Apps curates 100+ agents and skills across models such as GPT, Claude, Gemini, DeepSeek, Llama, and Qwen. Agent Skills focuses on production‑grade stages from definition to shipping, with quality‑gate controls.

The author suggests picking the workflow that matches one’s own process rather than installing everything, and customizing the SKILL.md files over time to teach the agent how the user wants software built.
