Is a Non-Developer Who Does Vibe Coding a Developer? (3)

AI coding agents have helped a non-developer move from creating small local HTML tools to building shared dashboards, integrations, automations, and repeatable workflows. The major change was not writing more code, but learning to define data, permissions, inputs, outputs, exceptions, and validation criteria. The author concludes that AI is making more kinds of work executable and structured, expanding questions about “development” beyond professional developers. ## From Local HTML to Shared Tools - Early tools were standalone HTML files used locally in a browser. - Sharing them introduced deployment, URLs, version updates, and maintenance concerns. - Once users needed persistent data and changing states, the problem expanded from UI design to: - Data storage - Access and edit permissions - Change history and rollback - Backups and operational responsibility - Google Sheets became a practical lightweight database because it already provided: - Collaboration and familiar interfaces - Permission management - Revision history - The author progressed from manually pasting Apps Script code to using `clasp` and Apps Script APIs for deployment and execution. - The key shift was learning to evaluate where data should live and which tools already work safely within an organization. ## Security as a Daily Habit - Connecting work tools through webhooks introduced the need to protect tokens and webhook URLs. - The author began using `.env` files and `.gitignore` to prevent secrets from entering source code or Git repositories. - Requests to AI agents increasingly included security requirements: - Read secrets from environment variables - Avoid printing sensitive values in logs - Use placeholders instead of real credentials - Small automations connected to external systems naturally required thinking about secret management, execution environments, and access control. ## Turning Manual Tasks into Workflows - Tasks such as copying files, organizing folders, converting documents, editing videos, and extracting audio or summaries were delegated to AI agents. - Delegating these tasks required explicit definitions of: - Input files - Output names and formats - Whether existing files may be overwritten - Failure conditions - Verification requirements - Informal, intuitive actions became structured work specifications. - The author found that understanding completion criteria and input/output formats was often more important than memorizing individual commands. ## Skills and Feedback Loops - Weekly meeting-note preparation revealed recurring editing patterns and implicit business rules. - These rules were encoded into Codex and Claude skills covering: - Note structure - Action-item extraction - PMO-related signals - Situations where the AI should ask questions instead of making assumptions - Skills functioned as stored decision criteria, not merely collections of prompts. - Comparing AI-generated drafts with the author’s final revisions enabled continuous refinement. - Deleting local data for security reasons accidentally removed useful conversation context, temporarily reducing skill quality and demonstrating the importance of preserving relevant operational knowledge. ## Using Outputs as New Inputs - Google Analytics reporting became more frequent and detailed through MCP-based API access and reusable reporting skills. - MCP provided the data connection, while skills preserved the recurring monthly report structure. - The valuable work remained interpreting changes between periods and deciding whether a change was meaningful. - Combining AI-generated metrics with the author’s contextual knowledge helped surface signals requiring further investigation in near real time. The author recommends focusing less on how much code AI can generate and more on how work can be clearly structured for AI execution. As agents become more capable, everyone—not only developers—will increasingly define inputs, outputs, permissions, security controls, repetition, and validation as part of everyday work.

Key Players in the Agentic AI Ecosystem: MCP Player 10 Wraps Up, and What’s Next!

Kakao’s first MCP Player 10 competition showcased how developers are using Model Context Protocol (MCP) to build practical agentic AI services. More than 150 teams participated, and ten finalists were selected for solutions addressing childcare, startup support, culture, gaming, legal research, and safety. Kakao plans to expand this ecosystem through the upcoming Agentic Player 10 competition and deeper integration with Kakao Tools. ## The MCP Player 10 Competition - The competition ran from December 19, 2025, to January 18, 2026, on Kakao’s PlayMCP open platform. - It emphasized: - Creativity - Everyday usefulness - Technical stability - The goal was to encourage developers to create MCP servers that solve real-world problems with AI. - Ten teams were selected after internal evaluation and received a share of 21 million won in support funding, along with opportunities to collaborate with Kakao. ## Award-Winning MCP Services ### 어린이ZIP: AI Assistant for Childcare Teachers - Automates administrative work for daycare and kindergarten teachers. - Analyzes uploaded activity photos to generate drafts of parent notices and childcare journals. - Remembers child-specific details such as allergies and pickup arrangements. - Produces personalized responses in a warm, professional tone. ### SeedUp: Startup Support-Program Research - Collects and analyzes fragmented government startup-support announcements. - Summarizes eligibility requirements and relevant opportunities. - Helps founders develop application strategies. - Supports natural-language requests such as finding weekly deadlines or analyzing an uploaded announcement. ### Other Selected Services - **공유 비밀의 방:** An anonymous platform for sharing and empathizing with personal stories and AI conversations. - **바우만 16 안티에이징솔루션:** Recommends skincare routines using the Baumann 16 skin-type classification, cosmetic ingredient data, and skin pH analysis. - **아라드도우미:** A Dungeon & Fighter assistant using RAG and Vision AI to analyze patch notes, item trends, and optimized character builds. - **키즈허브:** Aggregates public data such as emergency-room availability, childcare waiting lists, and child-development information. - **택배추적기:** Combines package tracking with AI-based detection of smishing URLs in delivery-related messages. - **ArtBridge:** Recommends performances and exhibitions from approximately 200,000 records across nine cultural categories, using location, budget, and preferences. - **KidSafe:** Detects harmful language and emotional-crisis signals in children’s chatbot conversations, escalating serious cases to guardians or professional resources. - **LexiLink_ko:** Searches and organizes statutes, court precedents, and administrative interpretations through natural-language queries. All ten MCP servers are now officially available through the PlayMCP platform. ## PlayMCP’s Future Direction - PlayMCP will remain a developer-focused environment for building and distributing MCP servers. - Kakao Tools, available through ChatGPT for Kakao, will focus on helping general users experience MCP-based services. - Kakao plans to connect the two platforms more closely. - Kakao is considering managed infrastructure, including: - Kakao Cloud-based server support - Automated deployment - Greater operational responsibility for MCP service stability - PlayMCP may also support richer in-app interfaces through JSON-based widgets, similar to those already available in ChatGPT for Kakao. ## The Next Competition: Agentic Player 10 Kakao announced a second competition, Agentic Player 10, designed to connect developer-created agents with Kakao Tools and expose them to a broader audience. The program is positioned as an opportunity for startups and aspiring founders to test their services with real users and potentially bring their agents into KakaoTalk. Developers interested in building practical AI agents are encouraged to use PlayMCP and participate in Agentic Player 10 as the next step in Kakao’s expanding agentic AI ecosystem.
