Fusion is a CLI that turns a raw product idea into a runnable FastAPI MVP using GitHub Copilot CLI as the engine.

Usage:

python -m fusion.main build "Idea goes here"

Or, after installing:

fusion build "Idea goes here"

Notes:

• Requires gh with the Copilot extension installed and authenticated.
• Copilot prompts are sent via stdin.
• Output directory defaults to a slugified version of the idea.
• Set FUSION_NO_AI=1 to skip Copilot and only create the temp directory.
• Logs are saved under .fusion/logs/run_YYYY_MM_DD_HHMMSS.txt in the generated repo.
