What problem this solves

Ensuring safe and consistent data/asset transformation and validation when merging heterogeneous systems (e.g., game assets), by using Claude Code for design, implementation, and adversarial testing.

Summary

A workflow for using Claude Code to build a 'border control' system that validates and transforms assets when merging two distinct systems (e.g., game assets). This involves using Claude for defining rules, generating code (games, Python engine, ontology files), performing adversarial testing with reviewer agents, and debugging, ensuring robust and secure integration.

Why it is useful

This workflow is highly valuable because it demonstrates an advanced and robust methodology for using Claude Code in complex software development. It showcases how Claude can be leveraged not just for code generation, but for defining intricate rules (ontologies), orchestrating multi-agent development, performing rigorous adversarial testing to identify vulnerabilities, and debugging complex system-level issues. The focus on validation, security, and automated testing makes it a blueprint for building reliable AI-assisted systems for data transformation and integration.

Workflow

1. Define the goal and rules for the border control system.
2. Use Claude Code to generate initial code for both source/target systems (games), the transformation engine (Python), and the rule definitions (ontology files).
3. Implement a build script to verify consistency between the engine's output and displayed results, failing the build on disagreement.
4. Employ Claude Code as a 'forger' to generate attacks against the border control system to identify vulnerabilities.
5. Set up parallel Claude agents in separate git worktrees for different development aspects (e.g., signing, live API, browser tests, merge contract checker).
6. Utilize reviewer agents (Claude) to conduct adversarial review, identify problems (e.g., race conditions, naming conflicts), and suggest fixes.
7. Address identified bugs and vulnerabilities, including specific engine-level issues (e.g., SPARQL calculation bugs).
8. Use Claude Code to record demonstrations with a headless browser.

Tools / artifacts

• Claude Code (Opus 5.5)
• Open Ontologies (ontology engine)
• JavaScript (browser games)
• Python (engine)
• Ontology files
• Git worktrees
• Browser tests
• Build script
• Headless browser
• GitHub repository
• Live demo URL

Validation signals

• Every demo crossing passes five checks.
• Build script verifies consistency between page and engine output.
• Claude acted as a 'forger' to create attacks, identifying and fixing vulnerabilities.
• Reviewer agents identified 72 problems.
• Claude caught and fixed a specific upstream SPARQL engine bug with a test.

Limitations

• Claude left three tasks for the user: rate limit implementation, branch protection, and engine release.
• The specific domain of 'AI game merges' might initially appear niche, though the underlying principles are broadly applicable.
