gsd-secure-phase
100 / 100 · Low risk
Fine to try.
Use to re-verify the threat mitigations of a phase that already shipped, or when the user asks to audit SECURITY.md. Audits an existing SECURITY.md, runs from a PLAN.md threat model, or exits if the phase never ran.
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/'gsd-secure-phase' ] || [ -L ~/.agents/skills/'gsd-secure-phase' ]; then echo 'A skill folder named gsd-secure-phase already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/coco-research/coco' "$d" && git -C "$d" checkout --quiet 'cd89f013b617f7eea982a9bbc60e992974fda2aa' -- 'systems/gsd/skills/gsd-secure-phase' && mkdir -p ~/.agents/skills && cp -R "$d"/'systems/gsd/skills/gsd-secure-phase' ~/.agents/skills/'gsd-secure-phase' && 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/'gsd-secure-phase' ~/.claude/skills/'gsd-secure-phase' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
