claude-command-converter

To convert Claude Code commands into portable skills, apply the converter to .claude/commands/*.md files to generate skills/<skill-name>/SKILL.md. The process preserves workflow logic while removing runtime-specific constructs for cross-runtime use.

A portable, runtime-agnostic agent skill is a self-contained SKILL.md definition that works across Claude Code, Codex CLI, Copilot, and other runtimes. It uses standard frontmatter with name and description instead of runtime-specific constructs.

Yes, converting Claude commands to skills preserves the original workflow. The transformation retains core processing logic and metadata while stripping runtime-specific references to ensure cross-runtime portability.

Yes, converted skills work across Claude Code, Codex CLI, Copilot, and other runtimes. The conversion removes runtime-specific constructs and generates a standardized SKILL.md format for cross-runtime compatibility.

A generated SKILL.md file requires frontmatter containing name and description fields. This standardized metadata replaces runtime-specific constructs while preserving the original command workflow.

You need to migrate .claude/commands files to the skills format when standardizing command definitions for use across multiple runtimes like Codex CLI or Copilot, rather than remaining restricted to Claude Code alone.
