Overview

Codex found the user's Claude login, installed Claude Code in a sandbox, and used it as a QA agent without being told how, leaving credentials untouched.

Workflow

Suggested implementation: Codex identifies an existing authenticated Claude OAuth session on the local machine. It installs Claude Code in a temporary folder, resolves Node runtime dependencies, and launches Claude as a non-interactive auditor. Codex disables Claude's editing capabilities and session persistence to ensure read-only access while withholding its own findings to maintain independence.

Reported result

Outcome unknown due to source unavailability. Proposed acceptance check: Verify that the secondary agent identifies unique defects missed by the primary agent without modifying source files. Measure success by the count of validated, non-duplicate defects found by the independent reviewer.

Human role

The original post does not say how a person stayed involved.

Limitations

Prerequisite: An active, authenticated OAuth session for the secondary tool must exist on the host machine. Constraint: The workflow relies on reusing existing credentials, which may violate security policies if not explicitly authorized. Integration uncertainty: Node runtime compatibility issues may require manual intervention. Human approval is required before granting any agent access to local authentication tokens.

Try it

Act as a DevOps engineer setting up an independent QA review pipeline. I have a local codebase at [replaceable path] and a list of suspected defects at [replaceable file]. My machine has an authenticated session for [replaceable tool, e.g., Claude Code]. 1. Check for existing authentication tokens for [replaceable tool] in standard config directories. 2. If found, install [replaceable tool] into a temporary directory [replaceable temp path]. 3. Resolve any runtime dependencies (e.g., Node.js) required for execution. 4. Launch [replaceable tool] in non-interactive, read-only mode to audit the codebase against the defect list. 5. Ensure the tool cannot edit files or persist session data. 6. Output a JSON report of unique defects found by the secondary agent that were not in the initial list. Before executing, perform a dry run on a sample file to verify permissions. Ask me for confirmation before accessing any credential files. If authentication is missing, stop and report the error.
