A GC AI engineering team ran a day-long hackathon using the typesafeai "Jev" agent framework and produced 38 projects and experiments in 12 hours. The crowd favorite, Jeventus, is a Slack-based group Tamagotchi - a sloth avatar that interprets chat to decide whether users are feeding, playing with, or putting it to bed (one user fed it an avocado sandwich). The event showcased how conversational signals can drive playful, shared interactions inside Slack and demonstrated Jev’s ability to map natural language to discrete agent behaviors quickly.
Beyond the sloth, the demos surfaced practical agent patterns: Skill Match suggests a matching skill while you draft a request, and Make This a Skill detects repeated tasks from chat, extracts steps and corrections, and drafts a reusable skill for approval. The team packaged these recurring patterns into a Jev design skill that coding agents can load when adding features. An interactive explorer collects all 38 projects with write-ups, PRs, and recordings, and the writeup documents lessons and design patterns for anyone who wants to reuse Jev in their codebase.
