What it is
Corey Haines’s marketing skill pack: 47 skills across SEO and content, conversion optimization, copywriting, paid ads and measurement, growth and retention, sales, and strategy. Installs through the skills CLI or the plugin marketplace.
How it was vetted
Read the repo at commit 6726476 (2026-07-16), ran the injection audit, and read
a sample of skill bodies and the bundled CLI scripts.
- About 8,000 always-on tokens across 47 skills (~175 each), roughly five times the Anthropic pack. The descriptions are keyword-stuffed to trigger well, which adds to the standing cost.
- Clean skill bodies. No injected self-promo: the author’s affiliate links live in the README, not in skill output. No telemetry, no hidden instructions.
- Bundled API wrappers. 64 Node scripts under
tools/clis/read vendor API keys from your environment and call the matching vendor API. They are opt-in, never always-on, each scoped to one vendor’s key, and support--dry-run. A skill has to ask the agent to run one, and you have to have set the key. - The fix is per-skill install.
