Fine to try.
Build students' capacity to interrogate a historical source before reading — asking who authored it, when, why, and what this means for reliability. Use when students read documents without attending to authorship.
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/'sourcing-skill-builder' ] || [ -L ~/.agents/skills/'sourcing-skill-builder' ]; then echo 'A skill folder named sourcing-skill-builder already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/GarethManning/education-agent-skills' "$d" && git -C "$d" checkout --quiet '135d6275e7db0657d70b147f46d3191c5430677d' -- 'skills/historical-thinking/sourcing-skill-builder' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/historical-thinking/sourcing-skill-builder' ~/.agents/skills/'sourcing-skill-builder' && 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/'sourcing-skill-builder' ~/.claude/skills/'sourcing-skill-builder' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
