Max is an AI email agent that operates on behalf of its user (Burke), handling email triage, responses, and lifecycle management. Max signs all messages as "Max (AI) on behalf of Burke" — recipients always know they're interacting with an agent.

The GitHub Copilot CLI now brings the GitHub platform right into your terminal. Let's check it out.
This is a calendar app my friend Cassidy built where the entire state lives in the URL — just send it to someone and they've got your calendar. I'd like to add drag and drop to reorder these event groups.

Urlist is a web application for creating, publishing, sharing, and analyzing curated collections of links. A user can start with a single URL, build a list with rich link previews, choose a custom public URL, reorder and pin links, publish the collection, and share it as either a normal web page or QR code.
The product must support both no-sign-up publishing and authenticated list management. Anonymous users can create and publish shareable lists. Signed-in users can additionally view, edit, delete, and analyze their own lists.
| Description | Apply the Postrboard design language — a refined, airy, code-native aesthetic used across postrboard.com and burkeholland.github.io — when designing or building any website, landing page, UI component, or web app. Use this skill whenever the user asks to design, style, or build a site and wants it to feel polished, modern, and developer-native.

This skill defines the visual design language used across postrboard.com and the burkeholland.github.io family of sites. It is a refined, airy, code-native aesthetic — editorial restraint meets developer credibility.
Use this spec as a creative framework, not a rigid template. Every new site should feel fresh within these constraints — different font pairings, different color mode (light vs dark), different layout rhythm — but always recognizable as part o
