+# Claude Skills Collection
+
+Custom Claude Code skills to replace heavy MCP servers with lightweight CLI wrappers.
+
+## Why This Repo?
+
+Some MCP servers consume massive amounts of context. This repo provides lightweight skill alternatives that:
+- ✅ Only load when invoked (vs. always loaded MCPs)
+- ✅ Use standard CLI tools (tea, gh, etc.)
+- ✅ Save context budget for actual work
+- ✅ Can be shared across projects
+
