# What We Built in a Week of Pure Vibe Coding Source: https://www.youtube.com/watch?v=Smaa28CKMsY Recap page: https://rapidrecap.app/video/Smaa28CKMsY Generated: 2026-01-29T19:32:59.329+00:00 --- ## Quick Overview The team built a new version of their 'Tastemaker' app, which they now call 'Swipe File,' in one week of focused 'vibe coding' by implementing an agent-native architecture that allows AI agents to collaborate on writing tasks, demonstrated by an agent rewriting an essay about board games to adhere to a specific style guide, resulting in a more profound and less superficial output. **Key Points:** - The team successfully built a new version of their writing assistant, renamed 'Swipe File' (previously 'Tastemaker'), in one week of intensive 'vibe coding.' - The core technical shift was adopting an agent-native architecture, allowing multiple AI agents (like Jack, Eleanor, and Rhea) to work in parallel on tasks. - A demonstration showed an agent rewriting an essay about board games, applying a complex style guide that emphasized philosophical depth, concrete details, and structural sophistication. - The original essay was critiqued for being too much like a case study, lacking the revelatory excavation called for in their style guide. - The style guide emphasized principles like maintaining intellectual honesty about complexity, expressing moral urgency without preachiness, and using layered sentence structures. - The final revised essay demonstrated the desired style, incorporating deeper analysis and balancing abstract concepts with concrete details. ![Screenshot at 01:42: Jack initiates the demonstration by running a simulation where the agent system, including characters like Kate, Eleanor, and Rhea, is tasked with identifying editorial coverage gaps based on January publication data.](https://ss.rapidrecap.app/screens/Smaa28CKMsY/00-01-42.jpg) **Context:** This video documents a 'vibe coding' week where the creators focused on rapidly developing a new version of their writing assistant tool, formerly known as 'Tastemaker' and now 'Swipe File.' The central concept discussed is moving toward 'agent-native architectures,' which involves structuring the application so multiple specialized AI agents can work collaboratively and concurrently on writing and analysis tasks, rather than relying on a single LLM interaction. ## Detailed Analysis The presentation kicks off with an introduction to the 'Demo Day' and the team's location in Panama, acknowledging potential internet flakiness. The core focus is demonstrating the progress made during a 'vibe coding' week, which centered on building an agent-native architecture for their writing tool, now called 'Swipe File.' Jack explains that this involved using log files from past research requests to trigger virtual agents (Jack, Eleanor, Rhea, Katie) to perform tasks in parallel, such as analyzing traffic data against published content to find coverage gaps, specifically noting under-covered topics like creative AI (Sora, Veo, Kling). The simulation showed agents discussing these gaps, with Eleanor pointing out the under-coverage of high-converting content like 'Thesis' and Jack confirming the data showing a conversion gap. Katie identified topic blind spots in creative AI (video, music, voice) where competitors were active. The demonstration then shifted to Katie showcasing the tool itself, which evolved from a procedural 6-9 month project into a week-long effort due to the agent-native approach. The tool now features a 'Snippets' section for collecting and tagging content, an 'Analyze' section for gaining insights based on these snippets, and a 'Style Guide' editor. Katie demonstrated applying the complex, highly philosophical style guide they developed (which emphasizes deep grounding, structural complexity, and intellectual honesty) to a sample essay about board games. The agent successfully rewrote the essay, transforming it from a straightforward case study into a piece exhibiting the desired philosophical depth and concrete grounding, proving the agent-native system's ability to adhere to complex stylistic instructions. ### Demo Day Introduction - Team located in Panama - Internet connectivity issues acknowledged - Excitement to show work from 'vibe coding' week - Mention of agent picking up Slack messages ### Agent-Native Architecture Simulation - Simulation run using past research data as triggers - Agents (Kate, Eleanor, Rhea) discuss coverage gaps in AI topics (e.g., Sora, Veo, Kling) - Analysis reveals 'Thesis' has high conversion but low publication frequency ### Swipe File Tool Features - New version of 'Tastemaker' called 'Swipe File' - Features include Dashboard (snippets, tags, insights), Snippets tab for managing clipped content, Tags for categorization, and Insights tab for content pattern analysis - Style Guide editor allows detailed, complex instructions ### Style Guide Application & Test - Katie demonstrates applying a complex style guide to an essay about board games - Style guide emphasizes philosophical depth, structural complexity, and intellectual honesty - Agent successfully rewrites the essay to match the complex style, moving beyond simple case study reporting ### Conclusion & Future Work - The agent-native setup allows for complex, multi-agent workflows - The style guide helps articulate complex writing goals - Future work includes an AI writing camp and further refinement of the agent framework. ![Screenshot at 00:00: The host appears via video call from a sunny, outdoor setting, kicking off the Demo Day presentation.](https://ss.rapidrecap.app/screens/Smaa28CKMsY/00-00-00.jpg) ![Screenshot at 01:42: The simulation begins, showing the pixel-art interface where agent characters receive instructions from their manager, Kate, to identify editorial coverage gaps.](https://ss.rapidrecap.app/screens/Smaa28CKMsY/00-01-42.jpg) ![Screenshot at 03:41: Katie introduces herself as the Staff Writer and AI Editorial Lead, preparing to demonstrate the product she helped revive.](https://ss.rapidrecap.app/screens/Smaa28CKMsY/00-03-41.jpg) ![Screenshot at 04:11: The screen switches to the 'Swipe File' application dashboard, showing content snippets and generated insights, illustrating the core functionality of the new tool.](https://ss.rapidrecap.app/screens/Smaa28CKMsY/00-04-11.jpg) ![Screenshot at 07:49: The presentation moves to the 'Style Guide' editor within Swipe File, displaying detailed, high-level writing instructions that the AI agents must follow.](https://ss.rapidrecap.app/screens/Smaa28CKMsY/00-07-49.jpg)
