skill-analyzer

Claude Code skill / MCP / prompt analyzer plugin. Combines transcript JSONL analysis (Skill tool invocation rate, MCP server/tool usage rate) with static analysis of SKILL.md / CLAUDE.md / instructions/*.md (character count, token estimation, n-gram duplication detection) to generate prioritized improvement proposals (deletion candidates, consolidation candidates, compression candidates) with estimated token savings. Read-only and side-effect-free; pairs with cost-monitor (Phase 1) for observability and is consumed by cost-optimizer (Phase 3) for automated optimization.
