95 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Configure email authentication so legitimate mail lands and spoofed mail is blocked. Covers SPF, DKIM, DMARC (with the p=none → p=quarantine → p=reject migration path), MTA-STS, TLS-RPT, ARC, and BIMI. Invoke when launching a new sending domain, when domains are being spoofed, or when transactional email is landing in spam.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'email-deliverability-security' ] || [ -L ~/.agents/skills/'email-deliverability-security' ]; then echo 'A skill folder named email-deliverability-security already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/yanacuti1121/Yana-AI' "$d" && git -C "$d" checkout --quiet '54d4aa9fa3241319f4d37212bd23826658bf6bed' -- '.claude/skills/gw360--email-deliverability-security' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/gw360--email-deliverability-security' ~/.agents/skills/'email-deliverability-security' && 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/'email-deliverability-security' ~/.claude/skills/'email-deliverability-security' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
