Developer compares Jinja2, Claude, and SkillSpec Converter for multi-format skill generation

A developer compared three methods for converting a skill definition into multiple formats: a custom Jinja2 script, direct prompts to Claude, and a self-built SkillSpec Converter. The Jinja2 script was fast for a single, controlled format but required significant effort to adapt for other targets. Claude was quick for a one-off conversion but inconsistently included required fields and had minor syntax errors in its output. The SkillSpec Converter, designed to handle multiple output formats like OpenClaw, Claude, Codex, and MCP, proved most effective for generating consistent outputs across all targets, despite requiring an initial development effort.
