codex-claude-cursor-loop_skill

Overview

This skill orchestrates a triple-AI engineering loop where Claude handles planning and final architectural review, Codex validates plans and reviews code, and Cursor implements and executes changes. It enforces sequential validation, continuous feedback, and session-managed implementation to maximize code quality and reduce defects. The loop repeats until all validations pass.

How this skill works

The workflow begins with Claude producing a structured implementation plan and assumptions. Codex evaluates that plan for logic, security, edge cases, and architecture flaws; feedback triggers plan refinement if needed. Once validated, Cursor implements the plan in a tracked session; Codex then performs a code review and Claude performs a final architectural check. If issues are found, Claude produces fix plans and Cursor applies fixes in the same session, repeating reviews until approval.

When to use it

• Building new features that require rigorous design and safety checks
• Refactoring critical code or systems where regressions must be minimized
• Implementing security-sensitive components (auth, crypto, data handling)
• Onboarding multi-AI workflows where traceability and session history matter
• Iterative development where repeated validation and fixes are expected

Best practices

• Always validate implementation plans with Codex before starting implementation
• Keep the same Codex and Cursor models for consistency across iterations
• Store and reuse the Cursor session ID for all follow-up fixes to preserve context
• Document assumptions, handoffs, and who produced each artifact at each phase
• Never skip Codex code review or Claude's final architectural review

Example use cases

• Design and implement a new microservice: Claude drafts the architecture, Codex validates, Cursor implements, then reviews and finalizes
• Add security hardening: Claude outlines threat model and fixes, Codex validates edge cases, Cursor applies patches in-session
• Large refactor: Claude breaks down steps, Codex checks for regression risks, Cursor executes changes while preserving session history
• Rapid prototype to production: iterate plan→validate→implement cycles until performance and security checks pass
