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/'proj-three-point-estimate' ] || [ -L ~/.agents/skills/'proj-three-point-estimate' ]; then echo 'A skill folder named proj-three-point-estimate already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/polar-bear-org/claude-skills' "$d" && git -C "$d" checkout --quiet '95f01806ca43f6ee788d0579743e35853b695930' -- 'packs/ai-for-project-management-pack/skills/proj-three-point-estimate' && mkdir -p ~/.agents/skills && cp -R "$d"/'packs/ai-for-project-management-pack/skills/proj-three-point-estimate' ~/.agents/skills/'proj-three-point-estimate' && 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/'proj-three-point-estimate' ~/.claude/skills/'proj-three-point-estimate' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
