harness-optimizer

Diagnose and improve Claude Code harness configurations based on Anthropic's harness design principles. Analyzes skills/, agents/, commands/, hooks/, plugin.json, CLAUDE.md, .mcp.json, and settings.json for 8 design principles: evaluator separation, context management, task decomposition, evaluation criteria, structured handoff, harness simplification, sprint contract, and feedback loop. Supports both plugin projects (with plugin.json) and non-plugin projects (CLAUDE.md + .claude/ only). Uses 2-layer diagnostics: Layer 1 signal collection via Grep/Glob, Layer 2 semantic judgment by LLM. Outputs PASS/FAIL/PARTIAL checklist with per-principle scores, health grade, and auto-fix suggestions.
