Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Analyze arbitrary session-exported ATIF (Agent Tool Interaction Format / Agent Trajectory Interchange Format, ATIF-v1.7) trajectories — not Harbor jobs/ and not raw .trace.json — reconstruct intent→tool→observation sequences, and derive evidence-backed improvements for LibrAgent builtin tools, prompts, execution policy, and export/harness contracts. Use for: session ATIF eval loops, exported *_trajectory.json review, tool/harness postmortems from UI export, "ATIF 분석", "AITF 분석", "trace-eval-loo…

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'trace-eval-loop' ] || [ -L ~/.agents/skills/'trace-eval-loop' ]; then echo 'A skill folder named trace-eval-loop already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/fritzprix/libr-agent' "$d" && git -C "$d" checkout --quiet '0679557c88a47a5b14b020b9785e0de95e0a1f94' -- '.agents/skills/trace-eval-loop' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/trace-eval-loop' ~/.agents/skills/'trace-eval-loop' && 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/'trace-eval-loop' ~/.claude/skills/'trace-eval-loop' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
