Developer Releases Open-Source AI Agent Skills Library for Consistent Coding Tasks

A developer has published a free, open-source GitHub repository called ai-agent-skills, containing drop-in markdown files designed to give AI coding agents consistent, specialised behaviour. Each skill is a single SKILL.md file combining YAML frontmatter — which tells the agent when to activate — and plain markdown instructions defining what rules to apply. The library currently includes nine skills covering areas such as git commit quality, Dockerfile best practices, REST API design, TypeScript strict mode, and production launch readiness. Because the skill files live inside a project's .agents/skills/ folder and are committed to the repository, the same standards are automatically shared across an entire development team. The project is compatible with Antigravity IDE and any AI agent capable of reading markdown instructions, requiring no plugins or code changes to set up.
