Alt3r3dP3rc3ption/chat2goal ? reverse-engineered prompt

Build me a small Python project called chat2goal that turns messy chat transcripts into clean, executable /goal prompts for agentic AI models.

I want it to take a transcript and rewrite it into a strict format with clear sections for the role, context, task, execution gate, and definition of done. The output should be easy to paste into tools like Claude, Cursor, or Codex, and it should feel like a proper goal loop prompt instead of a rambling chat recap.

Please also include the supporting files needed to package and release the skill in different formats, plus a simple build script that can generate downloadable zip files from the source. If there are validation checks for the skill format, include those too.

Keep it lightweight, no extra dependencies if possible, and make it easy for someone to install, build, and use right away.
