I Don't Write Code: How a Truck Parts Wholesaler Runs on 80 AI Skills and 5 Agents

See how 80 AI skills and 5 agents run a B2B truck parts wholesaler, including code generation, competitor scraping, and a verification gate.

Claude Code (Opus) BigCommerce GraphQL Playwright React Native GitHub Actions

Overview

I built the agentic system that runs a B2B heavy-duty truck parts wholesaler — a dealer mobile app on a BigCommerce backend, a competitor price-intelligence scraper, dealer analytics, and 80 purpose-built Claude Code skills plus 5 specialized subagents gluing it together. I’m not a software engineer. Agents write every line of code; my job is directing and verifying it, which is why verification ended up being the architecture instead of an afterthought.

Live on screen, three systems:

The arsenal — how 80 skills and 5 subagents are structured, how one gets invoked, and the counterargument agent whose only job is attacking my conclusions before I act on them.
The business pipelines — scraping a login-gated competitor B2B portal to diff catalog and pricing against ours, and pulling live BigCommerce data to answer questions like which dealers went quiet this month.
The verification gate — a Stop hook that runs typecheck and the test suite on every code change and blocks the agent from ending its turn on a failure. I’ll break something on purpose and let it catch me.

Real store, real dealers, real orders. Code, logs, and architecture on screen. No slides.

Claude Code (Opus)

Claude Code Opus is a terminal-based agentic tool that pairs Anthropic’s most intelligent model with direct filesystem access to automate complex engineering tasks.

Claude Code Opus transforms software development from manual tinkering into an industrial-scale process by combining the Claude Opus 4.6 model with a command-line interface. Unlike standard chat assistants, this agentic duo reads and writes files directly, executes terminal commands, and manages multi-step refactoring across massive codebases using a 1-million-token context window. It eliminates manual context-pasting by maintaining a local CLAUDE.md memory file and offers an effort parameter (low, medium, high) to balance deep reasoning with token efficiency. Engineers use it to find zero-day vulnerabilities, debug production environments in a loop, and delegate high-stakes planning that previously required constant human oversight.

BigCommerce GraphQL

BigCommerce GraphQL provides a powerful, flexible API for storefront data access.

BigCommerce GraphQL offers a robust API (Application Programming Interface) for developers to interact with storefront data. It enables precise data fetching, reducing over-fetching and under-fetching common with traditional REST APIs. This allows for highly customized and performant storefront experiences, giving developers the tools to build innovative solutions on the BigCommerce platform.

Playwright

Playwright is the Microsoft-developed, cross-browser automation framework: it drives Chromium, Firefox, and WebKit with one unified API for fast, reliable end-to-end testing.

Playwright delivers robust, cross-platform end-to-end testing, supporting all major rendering engines: Chromium, Firefox, and WebKit. Launched by Microsoft in January 2020, its core strength is a single API for multiple languages (TypeScript, Python, Java, .NET). The framework eliminates flaky tests through automatic waiting and provides full test isolation by creating a new browser context (a brand-new browser profile) for each test. Key tooling includes Codegen for recording actions and the Trace Viewer for deep post-mortem analysis of test failures (screencasts, live DOM snapshots). This architecture ensures reliable, high-speed execution across Windows, Linux, and macOS.

React Native

React Native is an open-source framework for building native mobile applications (iOS, Android) using JavaScript and React.

React Native is a powerful JavaScript framework, originally developed by Meta (Facebook), enabling developers to build truly native mobile applications for both iOS and Android from a single codebase. It utilizes the React declarative programming model and bridges JavaScript code to the native UI components of each platform, ensuring high performance and a genuine native look and feel. This approach allows teams to share up to 90% of code, drastically reducing development time and cost. Major companies like Facebook, Microsoft, and Shopify leverage React Native for their production apps, validating its scalability and efficiency for cross-platform development.

GitHub Actions

GitHub Actions automates your software workflows (CI/CD, testing, deployment) directly within your repository.

GitHub Actions is your native, event-driven automation platform: it executes custom workflows right inside your GitHub repository. Define multi-step jobs using YAML files, which must be stored in the `.github/workflows` directory. These workflows trigger on specific events, like a `push` to a branch or a `pull_request` opening. The platform supports world-class Continuous Integration and Continuous Deployment (CI/CD), letting you build, test, and deploy code across any language (e.g., Python, Node.js, Java). Runners—Linux, Windows, or macOS virtual machines—execute the jobs. For security, confidential data is managed via GitHub `secrets`, ensuring credentials stay out of your code.
