Fine to try.
Produce a periodic review of a second-brain vault: what was added, which topics are growing, what contradicts what, which questions are still open, and what is worth reading next. Use this skill whenever the user asks for a weekly or monthly review, asks what changed in their vault, what they have been learning about lately, or what they should look at next, and when a scheduled review task fires.

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/'second-brain-review' ] || [ -L ~/.agents/skills/'second-brain-review' ]; then echo 'A skill folder named second-brain-review 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 "$d" checkout --quiet '53aea8231aff3024352e21839dc08668f7ecc0b9' -- 'skills/second-brain-review' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/second-brain-review' ~/.agents/skills/'second-brain-review' && 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/'second-brain-review' ~/.claude/skills/'second-brain-review' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
