Builder Spotlight #7 This is a fun one. Asat Akhmedov built 'Which Happened First' at the @cognition | @DevinAI Hackathon in Budapest, a game where you can challenge your friends to order historical events chronologically with new daily challenges and worldwide player ratings. Be warned, once you open the link you'll probably end up playing for a while. Find the link to the game and Asat's LinkedIn in below 👇

Builder Spotlight #6 EAA Gatekeeper blocks a pull request if it breaks EU accessibility rules. Karim Hussain built it solo at the @cognition Hackathon in Budapest, on his first day using @DevinAI. It's a GitHub Action. On every PR it: 1. Checks only the JSX you changed 2. Comments on each problem line with the WCAG criterion, the EN 301 549 clause, the EAA reference and a suggested fix 3. Blocks the merge until it's fixed The legal citations come from a fixed table, not a model, so they can't be made up. Well done! Link to Karim's LinkedIn / EAA Gatekeeper repo in comments below!

Builder Spotlight #5 What if your coding agent doesn't need that expensive model every time? Amir Abdullah Zakaria built Preflight at the @cognition / @DevinAI Hackathon in Budapest. It scans a repo, creates a short task brief, then lets a cheaper model try first. If it fails, Preflight hands a better brief to a stronger model and trys again. In his test, Preflight helped a cheaper Haiku model solve all 5 seeded bugs while costing 32% less than using Sonnet. Reach Amir via LinkedIn & try out Preflight at the links below in comments 👇
