📅 Release Calendar Skill

Auto-generate "Everything [Team] shipped in X days" posters from real X posts

A Claude Code skill that pulls tweets, identifies product releases, and renders a brand-matched calendar poster — just like the viral Anthropic / OpenAI shipping velocity images.

What It Does

Given a company name and a date range, this skill:

1. Pulls real X posts from official accounts and founders (up to 200 posts per handle, including replies)
2. Filters to product releases — model launches, features shipped, integrations, milestones
3. Fetches brand assets — logo from lobehub/icons or the company website, team member avatars
4. Renders an HTML calendar — brand-matched colors, team avatar row, click-through tweet links
5. Screenshots to PNG — crisp 2× retina output, ready to share

Usage

Just tell Claude what you want in plain language:

English triggers:

• release calendar for Vercel
• everything Stripe shipped in 60 days
• shipping velocity poster for Linear
• make a calendar of Figma releases

Chinese triggers:

• 帮我做一个 Cursor 的 release calendar
• 做一张 OpenAI shipped in 60 days 的图
• [公司] 发布日历 / 盘点一下 [公司] 发布了什么

Claude will walk you through the setup interactively — browser choice, date range, background style.
