Most AI coding agents and automation tools support some form of skill or instruction file — a structured document that tells the agent how to perform a specific task. The problem is every platform uses a slightly different format: SKILL.md for Claude Code, AGENTS.md for Codex, .cursorrules for Cursor, agents.yaml + tasks.yaml for CrewAI, and so on.
SkillStarter eliminates the guesswork. You describe what you need, select your target platform, and it generates a correctly formatted skill file using AI — complete with the right frontmatter, structure, and conventions for that specific tool.
