Install it

View source on GitHub ↗

git clone --depth 1 --filter=blob:none --sparse https://github.com/edupegoretti/fluidz-skills.git /tmp/fluidz-skills
git -C /tmp/fluidz-skills sparse-checkout set "skills/composites/newsletter-monitor"
mkdir -p ~/.claude/skills/newsletter-monitor
cp -R "/tmp/fluidz-skills/skills/composites/newsletter-monitor/." ~/.claude/skills/newsletter-monitor/

Picked up without a restart. A project skill of the same name is shadowed by your personal one. For one repository only, swap ~/.claude/skills for .claude/skills. Claude Code docs ↗

The folder is the same in every client that implements the format — 46 of them — so if yours is not above, only the destination changes.

Before you install: this skill will not complete its job on a bare agent. It needs AGENTMAIL_API_KEY, which you have to obtain separately.

Downstream Skills

When newsletter signals are found, chain to:
