Developer Converts VS Code Prompt Files into Portable AI Agent Skills

A developer who previously used AI agents and MCP to automate website content updates identified key limitations in their original setup, including duplicated instructions across multiple prompt files and no automated verification or pull-request creation. The original prompts, stored as markdown files in a GitHub directory, were tightly coupled to VS Code's Copilot agent mode and could not be used with other AI tools like Claude Code or Goose. To address these issues, the developer began converting the prompts into portable 'agent skills' stored in a standardized format under a dedicated directory. The new skills use a standalone browser automation CLI instead of a Playwright MCP server, making them accessible to any AI agent with shell access. The migration aimed to eliminate duplicated logic, capture operational edge-case knowledge, and fully automate the branch, commit, and pull-request workflow.
