Cross-check coding agent answers with a second agent
The poster built a tool that automatically sends Claude Code responses to Codex for a second opinion, replacing manual copy-pasting. Task: Suggested implementation: Build a tool like Sage to automate cross-checking. It runs in a separate terminal, monitors the primary coding agent (e.g., Claude Code) in real time, and sends responses to a secondary model (e.g., Codex) for review while maintaining a persistent thread. Human role: Monitor the secondary agent's feedback and approve final code changes.; tools: Claude Code, Codex. Human role: The original post does not say how a person stayed involved.; limitations: Prerequisites: Access to both primary and secondary coding agents. Constraints: Authentication via ChatGPT Pro Codex subscription or API key is required. Note: Using '/clear' resets the conversation log, necessitating a rerun of the setup. Source reliability is low as the original URL returned a 403 error..

Overview
The poster built a tool that automatically sends Claude Code responses to Codex for a second opinion, replacing manual copy-pasting.
Workflow
Suggested implementation: Build a tool like Sage to automate cross-checking. It runs in a separate terminal, monitors the primary coding agent (e.g., Claude Code) in real time, and sends responses to a secondary model (e.g., Codex) for review while maintaining a persistent thread. Human role: Monitor the secondary agent's feedback and approve final code changes.
Reported result
Outcome unknown. The source claims fewer bugs and early detection of bad plans but provides no hard metrics. User comments suggest useful catches, but specific impact data is missing. Proposed acceptance check: Measure the reduction in post-deployment bugs compared to a baseline period without cross-checking.
Human role
The original post does not say how a person stayed involved.
Limitations
Prerequisites: Access to both primary and secondary coding agents. Constraints: Authentication via ChatGPT Pro Codex subscription or API key is required. Note: Using '/clear' resets the conversation log, necessitating a rerun of the setup. Source reliability is low as the original URL returned a 403 error.
Try it
I want to set up a cross-checking workflow for my coding tasks. Please help me configure a secondary agent to review outputs from my primary coding agent. Inputs: - Primary Agent: [replaceable: e.g., Claude Code] - Secondary Agent: [replaceable: e.g., Codex] - Project Context: [replaceable: brief description of current codebase] Steps: 1. Guide me through authenticating the secondary agent using [replaceable: API key or subscription]. 2. Explain how to run the secondary agent in a separate terminal to monitor the primary agent's output. 3. Provide a script or configuration to send each response from the primary agent to the secondary agent for review. 4. Ensure the secondary agent maintains a persistent thread for context. Deliverables: - A step-by-step setup guide. - A sample configuration file. Quality Check: - Verify that the secondary agent successfully receives and processes a test response. - Confirm that '/clear' behavior is documented. Safeguards: - Do not execute any code that modifies my files without my explicit confirmation. - Ask clarifying questions if authentication methods are unclear. - Start with a dry run on a non-critical file before applying to the main project.
