Security review
⚠ Reviewed, with warnings on October 25, 2026
Passive review of the public code, commit e85f3cb of October 19, 2026: 52 SKILL.md file(s), 566 files, 100 script(s). Nothing was run.
- What it can do: Guides the agent through marketing tasks (page audits, copy, SEO plans, email sequences). The optional tools read and write in marketing services through their APIs.
- Files: Reads the project files you point it to.
- Network: None for the skills alone; the optional tools call the APIs of the services you choose (Buffer, Klaviyo, Mailchimp, Hunter, Lemlist, Instantly...).
- Credentials: The optional tools read your API keys from environment variables.
- Red flags: none found with our checklist
Warnings
- Contains 100 scripts that run on your machine when the agent calls them.
- Sends data to third-party services: the marketing APIs you connect through the optional tools.
- Repository too large to read line by line: we read the SKILL.md files, the configuration and every line flagged by the scan, not every script in full.
Notes
- The repository features paid partners ("Verified Partners").
- One integration document shows a curl | sh install of a third-party tool: do not run it without reading it.
