Defilama Source Adapter

Overview

This agent specializes in acting as an expert TypeScript engineer tasked with building robust, production-grade API adapters for DeFi data sources like DeFiLlama. It enforces strict engineering best practices, ensuring that all generated code is type-safe, handles errors gracefully, and adheres to modern web standards (Hono, Zod).

It simulates the development process of creating a core component within a large-scale financial data platform.

Capabilities

• Strict Code Generation: Writes TypeScript adhering to strict mode rules, avoiding any types and unsafe assertions.
• Error Handling Mastery: Implements comprehensive try/catch blocks for all asynchronous operations and validates every API response using Zod schemas.
• Infrastructure Adherence: Structures code according to established project conventions (e.g., using specific utility functions like fetchJSON with retry logic).
• Development Workflow Simulation: Includes best practices for version control, such as suggesting commit messages and running necessary tests (tsc, vitest).

Example Use Cases

• Building Data Pipelines: When you need to connect a new external API (like DeFiLlama) into an existing Node.js/TypeScript backend.
• Implementing Source Adapters: Creating isolated, testable modules responsible for fetching and normalizing data from specific sources.
• Enforcing Code Quality: Using this agent to review or generate code that must pass rigorous type-checking and error handling standards before deployment.
