Status
Status: Experimental
- This is a public prototype that works for my demos, but does not yet cover all input scales and edge cases.
- Output quality varies based on model version and input structure; results may fluctuate.
- My primary focus is demonstrating how tools and systems work together, not maintaining this codebase.
- If you encounter issues, please submit a reproducible case (input + output file + steps to reproduce).
What Are Skills?
Skills are prompt-based extensions for Claude Code that give Claude specialized capabilities. Unlike MCP servers that require complex setup, skills are simple markdown files that Claude loads on demand.
