Install this skill
One command (all agents)
Runs the npx skills CLI which auto-detects every AI coding agent you have installed (Claude Code, Cursor, Codex, OpenCode, Windsurf, Copilot, and 51 more).

Use it
Once installed, ask your agent to "use the dd-llmo-eval-trace-rca skill" or describe what you want (e.g. "Root-cause LLM app failures using eval traces"). Most agents auto-discover the skill from its SKILL.md description — no slash command needed.
