Fine to try.

Diagnose why a scored answer failed and who owns the fix, then cluster the failures by shared root cause. Walk dataset, agent-call, get_context/model, get_context/retrieval, construction, then model-definition. Append issue events to the file ledger, linked by traceId, one per cluster. Use after eval-answer, when triaging a run, or before changing a model. Does not edit the model (eval-improve).

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'eval-diagnose' ] || [ -L ~/.agents/skills/'eval-diagnose' ]; then echo 'A skill folder named eval-diagnose already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/malloydata/publisher' "$d" && git -C "$d" checkout --quiet 'bb8ce0db61c90d45273e4b65c5ccfc6475a9193a' -- 'skills/eval-diagnose' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/eval-diagnose' ~/.agents/skills/'eval-diagnose' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'eval-diagnose' ~/.claude/skills/'eval-diagnose' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
