Converted MemoryGraph from MCP server to Claude Code skill to reduce token cost. MCP tools were always in context (~45 tools eating tokens every turn). Skill loads on-demand only when triggered.

Implementation:
- Created ~/.claude/skills/memorygraph/ with client.py (620 lines), SKILL.md, SCHEMA.md, feature.json
- Direct SQLite access to ~/.memorygraph/memory.db bypassing MCP protocol
- JSON-based search instead of FTS (existing FTS index wasn't populated)
- CLI interface: store, recall, get, relate, search, update, delete, related, stats, recent

All 11 core operations implemented:
- store_memory, recall_memories, get_memory, create_relationship (high priority)
- search_memories, update_memory, delete_memory, get_related_memories (medium)
- get_memory_statistics, get_recent_activity (low)

Updated ~/.claude/CLAUDE.md Memory Protocol to use CLI commands instead of MCP tools.
