SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill enables the use of external AI CLI tools like Codex and Gemini to perform coding tasks, reducing costs and leveraging cross-model adversarial review to improve code quality.

Core Features & Use Cases

  • Cost Optimization: Utilize cheaper external models for implementation and review.
  • Adversarial Review: Employ different AI models to review each other's work, catching blind spots.
  • Flexible Tooling: Adapts to available tools (Codex, Gemini, Claude) with a defined escalation model.
  • Use Case: When implementing a complex feature, delegate the initial coding to Codex, have Gemini review it, and then have Claude perform a final review, ensuring robustness and cost-effectiveness.

Quick Start

Use the external-tools skill to delegate the implementation of the new user authentication module to Codex.

FAQPage Schema
How do I use Codex and Gemini for code review to reduce Claude API costs?

To reduce Claude API costs for code review, you can delegate coding tasks to cheaper external CLI tools like Codex and Gemini. This approach uses a configurable escalation model to manage budget constraints and sandboxed execution.

What is cross-model adversarial review and how does it improve code quality?

Cross-model adversarial review employs different AI models to review each other's work, catching blind spots. By orchestrating interactions between Codex, Gemini, and Claude, it ensures robustness and improves overall code quality.

Can I use external AI CLI tools with Claude for feature implementation?

Yes, you can use external AI CLI tools with Claude for feature implementation. The system adapts to available tools with a defined escalation model, allowing you to delegate initial coding to Codex and have Gemini perform the review.

How do I handle tool availability and errors when delegating tasks to external AI models?

When delegating tasks to external AI models, the system manages tool availability and error handling through a configurable escalation model. This ensures execution falls back gracefully across Codex, Gemini, and Claude.

What is the best way to orchestrate interactions between Codex, Gemini, and Claude?

The best way to orchestrate interactions between Codex, Gemini, and Claude is through a defined escalation model that manages budget constraints and sandboxed execution, allowing you to leverage cheaper models for implementation and review.

Are there limitations to using external CLI tools for cost optimization in software engineering?

Limitations when using external CLI tools for cost optimization include managing tool availability and potential error handling issues. The system mitigates these with a configurable escalation model and sandboxed execution to maintain code quality.
