During January 2026, Vaayne developed a project-specific rules extension for the coding agent in the badlogic/pi-mono repository. This extension enabled the agent to dynamically load and apply contextual rules by scanning a designated directory for markdown files, ensuring adherence to project guidelines during automated workflows. Vaayne implemented the solution using TypeScript and Node.js, leveraging file system operations to discover, parse, and enforce per-project rules. The work included an example extension for Claude rules, demonstrating reproducible rule application across projects. The feature addressed the need for flexible, context-aware automation, reflecting a focused and well-scoped engineering effort within extension development.
