Convert a posthog.com blog or newsletter post into a markdown file formatted for posting as an X (Twitter) Article. Strips frontmatter, promotes the title to an H1, remaps headings to X's two heading levels (subheadings + bold), downloads all post images into a numbered folder, and appends a subscribe CTA for newsletters. Use when the user wants to copy a post from contents/blog/ or contents/newsletter/ into X Article format.

Convert a Substack newsletter post into a native posthog.com newsletter file. Fetches the content from a Substack URL, formats it with correct frontmatter and markdown, applies internal links, and writes image placeholders. Omits Substack-specific sections (byline, related texts, job posts). Use when the user provides a newsletter.posthog.com URL and asks to post it natively.

Verify and update competitor product data by scraping competitor websites using WebFetch/WebSearch. Use when the user asks to verify, check, or update competitor information in competitorData files (like amplitude.tsx, mixpanel.tsx), or when they want to ensure competitor feature data is accurate and current. This skill systematically checks product features, pricing, platform details, and generates update recommendations with source URLs for verification.
