Fine to try.

Scaffold a first eval suite for an agent: mine real failures into cases, write behavioural checks over traces, and generate the runner. Use when the user wants evals, regression tests for an agent, a golden set, or asks how to know a prompt/model change did not break things. Do NOT use for a single task's done-check (goal-test) or for auditing context (context-audit).

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/'evals-bootstrap' ] || [ -L ~/.agents/skills/'evals-bootstrap' ]; then echo 'A skill folder named evals-bootstrap already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/undefined-ui/second-brain-os' "$d" && git -C "$d" checkout --quiet '53aea8231aff3024352e21839dc08668f7ecc0b9' -- 'plugins/agents-course/skills/evals-bootstrap' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/agents-course/skills/evals-bootstrap' ~/.agents/skills/'evals-bootstrap' && 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/'evals-bootstrap' ~/.claude/skills/'evals-bootstrap' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
