Purpose

Write or improve marketing copy for pages, ads, emails, etc. Strong emphasis on value prop, specificity, and audience fit; often paired with cro.

Harness Coverage

Target agents: antigravity, claude-code, codex, crush, cursor, gemini-cli, github-copilot, grok, opencode. All skills in the bundle cross-reference the product-marketing context document first and share related-skills sections.

Trust And Risks

install-now-after-trust-gate / curated-trust-gated (core marketing tier plus residual tier). High-install community bundle from a recognized practitioner (Corey Haines). Content is guidance; actual tactics must be adapted to current platform TOS, privacy law, deliverability rules, and brand. Some skills (ads, cold-email, paywalls) touch regulated or reputation-sensitive surfaces.

Comparable Alternatives

Framework or channel-specific guides (Google Ads docs, Klaviyo/Mailchimp playbooks, traditional CRO resources, competitor tools such as Ahrefs/Semrush skills when available). Local playbooks and analytics-driven experimentation replace generic advice over time.
